Scientists believe this kind of ice could be an excellent place to look for microbial life on Mars today.

Researchers think meltwater beneath Martian ice could support microbial life.

While actual evidence for life on Mars has never been found, a new NASA study proposes microbes could find a potential home beneath frozen water on the planet’s surface.

Through computer modeling, the study’s authors have shown that the amount of sunlight that can shine through water ice would be enough for photosynthesis to occur in shallow pools of meltwater below the surface of that ice. Similar pools of water that form within ice on Earth have been found to teem with life, including algae, fungi, and microscopic cyanobacteria, all of which derive energy from photosynthesis.

“If we’re trying to find life anywhere in the universe today, Martian ice exposures are probably one of the most accessible places we should be looking,” said the paper’s lead author, Aditya Khuller of NASA’s Jet Propulsion Laboratory in Southern California.

Mars has two kinds of ice: frozen water and frozen carbon dioxide. For their paper, published in Nature Communications Earth & Environment, Khuller and colleagues looked at water ice, large amounts of which formed from snow mixed with dust that fell on the surface during a series of Martian ice ages in the past million years. That ancient snow has since solidified into ice, still peppered with specks of dust.  

Although dust particles may obscure light in deeper layers of the ice, they are key to explaining how subsurface pools of water could form within ice when exposed to the Sun: Dark dust absorbs more sunlight than the surrounding ice, potentially causing the ice to warm up and melt up to a few feet below the surface.

Mars scientists are divided about whether ice can actually melt when exposed to the Martian surface. That’s due to the planet’s thin, dry atmosphere, where water ice is believed to sublimate — turn directly into gas — the way dry ice does on Earth. But the atmospheric effects that make melting difficult on the Martian surface wouldn’t apply below the surface of a dusty snowpack or glacier.

Thriving Microcosms

On Earth, dust within ice can create what are called cryoconite holes — small cavities that form in ice when particles of windblown dust (called cryoconite) land there, absorb sunlight, and melt farther into the ice each summer. Eventually, as these dust particles travel farther from the Sun’s rays, they stop sinking, but they still generate enough warmth to create a pocket of meltwater around them. The pockets can nourish a thriving ecosystem for simple lifeforms..

“This is a common phenomenon on Earth,” said co-author Phil Christensen of Arizona State University in Tempe, referring to ice melting from within. “Dense snow and ice can melt from the inside out, letting in sunlight that warms it like a greenhouse, rather than melting from the top down.”

Christensen has studied ice on Mars for decades. He leads operations for a heat-sensitive camera called THEMIS (Thermal Emission Imaging System) aboard NASA’s 2001 Mars Odyssey orbiter. In past research, Christensen and Gary Clow of the University of Colorado Boulder used modeling to demonstrate how liquid water could form within dusty snowpack on the Red Planet. That work, in turn, provided a foundation for the new paper focused on whether photosynthesis could be possible on Mars.

In 2021, Christensen and Khuller co-authored a paper on the discovery of dusty water ice exposed within gullies on Mars, proposing that many Martian gullies form by erosion caused by the ice melting to form liquid water.

This new paper suggests that dusty ice lets in enough light for photosynthesis to occur as deep as 9 feet (3 meters) below the surface. In this scenario, the upper layers of ice prevent the shallow subsurface pools of water from evaporating while also providing protection from harmful radiation. That’s important, because unlike Earth, Mars lacks a protective magnetic field to shield it from both the Sun and radioactive cosmic ray particles zipping around space.

The study authors say the water ice that would be most likely to form subsurface pools would exist in Mars’ tropics, between 30 degrees and 60 degrees latitude, in both the northern and southern hemispheres.

Khuller next hopes to re-create some of Mars’ dusty ice in a lab to study it up close. Meanwhile, he and other scientists are beginning to map out the most likely spots on Mars to look for shallow meltwater — locations that could be scientific targets for possible human and robotic missions in the future.

Jacquelyn Shuman, FireSense Project Scientist at NASA Ames Research Center, originally wanted to be a veterinarian. By the time she got to college, Shuman had switched interests to biology, which became a job teaching middle and high school science. Teaching pivoted to finance for a year, before Shuman returned to the science world to pursue a PhD.

It was in a forest ecology class taught by her future PhD advisor, Herman “Hank” Shugart, that she first discovered a passion for ecosystems and dynamic vegetation that led her into the world of fire science, and eventually to NASA Ames.

While Shuman’s path into the world of fire science was not a direct one, she views her diverse experiences as the key to finding a fulfilling career. “Do a lot of different things and try a lot of different things, and if one thing isn’t connecting with you, then do something different,” Shuman said.

Diving into the World of Fire

Shuman’s PhD program focused on boreal forest dynamics across Russia, examining how the forest changes in response to climate change and wildfire. During her research, she worked mainly with scientists from Russia, Canada, and the US through the Northern Eurasia Earth Science Partnership Initiative (NEESPI), where Shugart served as the NEESPI Chief Scientist. “The experience of having a highly supportive mentor, being a part of the NEESPI community, and working alongside other inspiring female scientists from across the globe helped me to stay motivated within my own research,” Shuman said.

After completing her PhD, Shuman wanted to become involved in collaborative science with a global impact, which led her to the National Center for Atmospheric Research (NCAR). There, she spent seven years working as a project scientist on the Next Generation Ecosystem Experiment NGEE-Tropics) on a dynamic vegetation model project called FATES (Functionally Assembled Terrestrial Ecosystem Simulator). As part of the FATES team, Shuman used computer modeling to test vegetation structure and function in tropical and boreal forests after wildfires, and was the lead developer for updating the fire portion of the model.

This figure shows fire characteristics from an Earth system model that uses vegetation structure and interactive fire. The FATES model captures the fire intensity associated with burned land and grass growth in the Southern Hemisphere. Shuman et al. 2024 GMD

Fire has also played a powerful role in Shuman’s personal life. In 2021, the Marshall Fire destroyed neighborhoods near her hometown of Boulder, Colorado, causing over $513 million of damage and securing its place as the state’s most destructive wildfire. Despite this, Shuman is determined to not live in fear. “Fire is part of our lives, it’s a part of the Earth system, and it’s something we can plan for. We can live more sustainably with fires.” The way to live safely in a fire-inclusive ecosystem, according to Shuman, is to develop ways to accurately track and forecast wildfires and smoke, and to respond to them efficiently: efforts the fire community is continuously working on improving.

The Fire Science Community

Collaboration is a critical element of wildland fire management. Fire science is a field that involves practitioners such as firefighters and land managers, but also researchers such as modelers and forecasters; the most effective efforts, according to Shuman, come when this community works together. “People in fire science might be out in the field and carrying a drip torch and marching along in the hilltops and the grasslands or be behind a computer and analyzing remote sensing data,” Shuman said. “We need both pieces.”

Protecting communities from wildfire impacts is one of the most fulfilling aspects of Shuman’s career, and a goal that unites this community. “Fire research poses tough questions, but the people who are thinking about this are the people who are acting on it,” Shuman said. “They are saying, ‘What can we do? How can we think about this? What information do we need? What are the questions?’ It’s a special community to be a part of.”

Looking to the Future of Fire

Currently at NASA Ames Research Center, Shuman is the Project Scientist for FireSense: a project focused on delivering NASA science and technology to practitioners and operational agencies. Shuman acts as the lead for the project office, identifying and implementing tools and strategies. Shuman still does ecosystem modeling work, including implementing vegetation models that forecast the impact of fire, but also spends time traveling to active fires across the country so she can help partners implement NASA tools and strategies in real time.

“Right now, many different communities are all recognizing that we can partner to identify the best path forward,” Shuman said. “We have an opportunity to use everyone’s strengths and unique perspectives. It can be a devastating thing for a community and an ecosystem when a fire happens. Everyone is interested in using all this collective knowledge to do more, together.”

Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA pilots Nils Larson and Wayne Ringelberg head for a mission debrief after flying a NASA F/A-18 at Mach 1.38 to create sonic booms as part of the Sonic Booms in Atmospheric Turbulence flight series at NASA’s Armstrong Flight Research Center in California, to study sonic boom signatures with and without the element of atmospheric turbulence.NASA/Lauren Hughes

NASA research pilots are experts on how to achieve the right flight-test conditions for experiments and the tools needed for successful missions. It is that expertise that enables pilots to help researchers learn how an aircraft can fly their technology innovations and save time and money, while increasing the innovation’s readiness for use.

NASA pilots detailed how they help researchers find the right fit for experiments that might not advance without proving that they work in flight as they do in modeling, simulation, and ground tests at the Ideas to Flight Workshop on Sept. 18 at NASA’s Armstrong Flight Research Center in Edwards, California. “Start the conversation early and make sure you have the right people in the conversation,” said Tim Krall, a NASA Armstrong flight operations engineer. “What we are doing better is making sure pilots are included earlier in a flight project to capitalize on their experience and knowledge.”

Flight research is often used to prove or refine computer models, try out new systems, or increase a technology’s readiness. Sometimes, pilots guide a research project involving experimental aircraft. For example, pilots play a pivotal role on the X-59 aircraft, which will fly faster than the speed of sound while generating a quiet thump, rather than a loud boom. In the future, NASA’s pilots with fly the X-59 over select U.S. communities to gather data about how people on the ground perceive sonic thumps. NASA will provide this information to regulators to potentially change regulations that currently prohibit commercial supersonic flight over land.

“We have been involved with X-59 aircraft requirements and design process from before it was an X-plane,” said Nils Larson, NASA chief X-59 aircraft pilot and senior advisor on flight research. “I was part of pre-formulation and formulation teams. I was also on the research studies and brought in NASA pilot Jim Less in for a second opinion. Because we had flown missions in the F-15 and F-18, we knew the kinds of systems, like autopilots, that we need to get the repeatability and accuracy for the data.”

NASA pilots’ experience can provide guidance to enable a wide range of flight experiments. A lot of times researchers have an idea of how to get the required flight data, but sometimes, Larson explains, while there are limits to what an aircraft can do – like flying the DC-8 upside down, there are maneuvers that given the right mitigations, training, and approval could simulate those conditions.

Less says he’s developed an approach to help focus researchers: “What do you guys really need? A lot of what we do is mundane, but anytime you go out and fly, there is some risk. We don’t want to take a risk if we are going after data that nobody needs, or it is not going to serve a purpose, or the quality won’t work.”

Sometimes, a remotely piloted aircraft can provide an advantage to achieve NASA’s research priorities, said Justin Hall, NASA Armstrong’s subscale aircraft laboratory chief pilot. “We can do things quicker, at a lower cost, and the subscale lab offers unique opportunities. Sometimes an engineer comes in with an idea and we can help design and integrate experiments, or we can even build an aircraft and pilot it.” 

Most research flights are straight and level like driving a car on the highway. But there are exceptions. “The more interesting flights require a maneuver to get the data the researcher is looking for,” Less said. “We mounted a pod to an F/A-18 with the landing radar that was going to Mars and they wanted to simulate Martian reentry using the airplane. We went up high and dove straight at the ground.”

Another F/A-18 experiment tested the flight control software for the Space Launch System rocket for the Artemis missions. “A rocket takes off vertically and it has to pitch over 90 degrees,” Less explained. “We can’t quite do that in an F-18, but we could start at about a 45-degree angle and then push 45 degrees nose low to simulate the whole turn. That’s one of the fun parts of the job, trying to figure out how to get the data you want with the tools we have.”

A salute is widely recognized as a display of respect, but did you know it also means ‘hello’ in American Sign Language?

It is one of the signs that Jesse Bazley, International Space Station/Commercial Low Earth Orbit Development Program integration team lead, subtly incorporates into his daily interactions with colleagues at NASA’s Johnson Space Center in Houston.

Bazley is hard of hearing, which has at times presented challenges in his daily work – particularly during his stint as an Environmental and Thermal Operating Systems flight controller for the space station. “Working on console [in the Mission Control Center], you must listen to dozens of voice loops at a time, sometimes in different languages,” he said, adding that the standard-issue headset for flight controllers was not compatible with his hearing aids. Bazley adapted by obtaining a headset that fit over his hearing aids, learning how to adjust the audio system’s volume, and limiting over-the-air discussions when possible.

Bazley has been part of the NASA team for 17 years, filling a variety of roles that support the International Space Station. One of his proudest achievements occurred early in his tenure. Bazley was an intern at Marshall Space Flight Center in Huntsville, Alabama, in 2006 when the space station’s Water Recovery System was being tested. The system converts the station’s wastewater into drinkable water for the crew. When he arrived at Johnson one year later, his first assignment was to assist with the system’s procedure and display development for its incorporation into the space station’s core operations. “Now, 16 years later, it is commonplace for the space station to ‘turn yesterday’s coffee into tomorrow’s coffee’,” he said.

His favorite project so far has been integrating the station’s Thermal Amine Scrubber – which removes carbon dioxide from the air – into station operations. “I worked it from the beginning of NASA’s involvement, helping the provider with software testing and the integration of a brand-new Mission Control Center communications architecture,” he said.

Today, Bazley works to integrate subject matter experts from Johnson’s Flight Operations Directorate (FOD) into the processes of the International Space Station and Commercial Low Earth Orbit Development Programs. “I help pull together FOD positions on topics and coordinate reviews of provider materials to ensure that the operations perspective is maintained as development moves forward,” he explained.

While Bazley no longer supports a console, he must continue adapting to difficult hearing environments. He uses the captioning tools available through videoconferencing software during frequent team meetings, for example. “It’s important to understand that people have visible and invisible disabilities,” he said. “Sometimes their request for a remote option is not because they want to avoid an in-person meeting. It may be that they work best using the features available in that virtual environment.”

Bazley also chairs the No Boundaries Employee Resource Group, which promotes the development, inclusion, and innovation of Johnson’s workforce with a focus on employees with disabilities and employees who are caregivers of family members with disabilities.

From these diverse roles and experiences, Bazley has learned to listen to his gut instincts. “In flight operations, you must work with short timelines when things happen in-orbit, so you have to trust your training,” he said. “Understanding when you have enough information to proceed is critical to getting things done.”

Bazley looks forward to the further commercialization of low Earth orbit so NASA can focus resources on journeying to the Moon and Mars. “Aviation started out as government-funded and now is commonplace for the public. I look forward to seeing how that evolution progresses in low Earth orbit.”

His advice to the Artemis Generation is to consider the long-term impact of their actions and decisions. “What looks great on paper may not be a great solution when you have to send 10 commands just to do one task, or when the crew has to put their hand deep into the spacecraft to actuate a manual override,” he said. “The decisions you make today will be felt by operations in the future.”

Preparations for Next Moonwalk Simulations Underway (and Underwater) Farms in California’s Sacramento-San Joaquin River Delta face strict reporting requirements for water usage because the delta supplies most of the state’s freshwater. This Landsat image uses infrared wavelengths to depict vegetation.Credit: U.S. Geological Survey

The 30-acre pear orchard in the Sacramento-San Joaquin River Delta has been in Brett Baker’s family since the end of the Gold Rush. After six generations, though, California’s most precious resource is no longer gold – it’s water. And most of the state’s freshwater is in the delta. 

Landowners there are required to report their water use, but methods for monitoring were expensive and inaccurate. Recently, however, a platform called OpenET, created by NASA, the U.S. Geological Survey (USGS), and other partners, has introduced the ability to calculate the total amount of water transferred from the surface to the atmosphere through evapotranspiration. This is a key measure of the water that’s actually being removed from a local water system. It’s calculated based on imagery from Landsat and other satellites. 

 “It’s good public policy to start with a measure everyone can agree upon,” Baker said. 

OpenET is only one of the latest uses researchers and businesses continue finding for Landsat over 50 years after the program started collecting continuous imagery of Earth’s surface. NASA has built and launched all nine of the satellites before handing them over to USGS, which manages the program. 

Some of the most pressing questions people ask about Earth are about the food it’s producing. Agriculture and adjacent industries are among the heaviest users of Earth-imaging data, which can help assess crop health and predict yields. 

The latest Landsat satellite, Landsat 9, went into orbit in fall of 2021. NASA and the USGS are already developing options for the next iteration of Landsat, currently known as Landsat Next.Credit: NASA

Even in this well-established niche, though, new capabilities continue to emerge. One up-and-coming company is using Landsat to validate sustainable farming practices by measuring carbon stored in the ground, which can be detected in the reflectance rate in certain wavelengths. This is how Perennial Inc. is enabling emerging markets for carbon credits, through which farmers get paid for maximizing their land’s storage of carbon. 

The company is also discovering interest among food companies that want to reduce their environmental impact by choosing eco-conscious suppliers, as well as companies in the fertilizer, farm equipment, and agricultural lending businesses. 

Landsat also enables countless map-based apps, studies of changes in Earth’s surface cover over half a century, and so much more.

New Team to Assess NASA’s Mars Sample Return Architecture Proposals

NASA announced Wednesday a new strategy review team will assess potential architecture adjustments for the agency’s Mars Sample Return Program, which aims to bring back scientifically selected samples from Mars, and is a key step in NASA’s quest to better understand our solar system and help answer whether we are alone in the universe.

Earlier this year, the agency commissioned design studies from the NASA community and eight selected industry teams on how to return Martian samples to Earth in the 2030s while lowering the cost, risk, and mission complexity. The new strategy review team will assess 11 studies conducted by industry, a team across NASA centers, the agency’s Jet Propulsion Laboratory in Southern California, and the Johns Hopkins Applied Physics Laboratory. The team will recommend to NASA a primary architecture for the campaign, including associated cost and schedule estimates.

“Mars Sample Return will require a diversity of opinions and ideas to do something we’ve never done before: launch a rocket off another planet and safely return samples to Earth from more than 33 million miles away,” said NASA Administrator Bill Nelson. “It is critical that Mars Sample Return is done in a cost-effective and efficient way, and we look forward to learning the recommendations from the strategy review team to achieve our goals for the benefit of humanity.”

Returning samples from Mars has been a major long-term goal of international planetary exploration for more than three decades, and the Mars Sample Return Program is jointly planned with ESA (European Space Agency). NASA’s Perseverance rover is collecting compelling science samples that will help scientists understand the geological history of Mars, the evolution of its climate, and potential hazards for future human explorers. Retrieval of the samples also will help NASA’s search for signs of ancient life.

The team’s report is anticipated by the end of 2024 and will examine options for a complete mission design, which may be a composite of multiple studied design elements. The team will not recommend specific acquisition strategies or partners. The strategy review team has been chartered under a task to the Cornell Technical Services contract. The team may request input from a NASA analysis team that consists of government employees and expert consultants. The analysis team also will provide programmatic input such as a cost and schedule assessment of the architecture recommended by the strategy review team.

The Mars Sample Return Strategy Review Team is led by Jim Bridenstine, former NASA administrator, and includes the following members:

• Greg Robinson, former program director, James Webb Space Telescope
• Lisa Pratt, former planetary protection officer, NASA
• Steve Battel, president, Battel Engineering; Professor of Practice, University of Michigan, Ann Arbor
• Phil Christensen, regents professor, School of Earth and Space Exploration, Arizona State University, Tempe
• Eric Evans, director emeritus and fellow, MIT Lincoln Lab
• Jack Mustard, professor of Earth, Environmental, and Planetary Science, Brown University
• Maria Zuber, E. A. Griswold professor of Geophysics and presidential advisor for science and technology policy, MIT

The NASA Analysis Team is led by David Mitchell, chief program management officer at NASA Headquarters, and includes the following members:

• John Aitchison, program business manager (acting), Mars Sample Return
• Brian Corb, program control/schedule analyst, NASA Headquarters
• Steve Creech, assistant deputy associate administrator for Technical, Moon to Mars Program Office, NASA Headquarters

Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA operations engineer Daniel Velasquez, left, is reviewing the Mobile Vertipad Sensor Package system as part of the Air Mobility Pathways test project at NASA’s Armstrong Flight Research Center in Edwards, California, on Oct. 17, 2023.NASA/Steve Freeman

Lee esta historia en Español aquí.

Born and raised in Peru, Daniel Velasquez moved to the United States when he was 10 years old. While that decision was a big transition for his family, it also created many opportunities for him. Now Velasquez is an operations engineer for NASA’s Air Mobility Pathfinders project at NASA’s Armstrong Flight Research Center in Edwards, California.

Velasquez develops flight test plans for electric vertical take-off and landing (eVTOL) aircraft, specifically testing how they perform during various phases of flight, such as taxi, takeoff, cruise, approach, and landing. He was drawn to NASA Armstrong because of the legacy in advancing flight research and the connection to the Space Shuttle program.

“Being part of a center with such a rich history in supporting space missions and cutting-edge aeronautics was a major motivation for me,” Velasquez said. “One of the biggest highlights of my career has been the opportunity to meet (virtually) and collaborate with an astronaut on a possible future NASA project.”

Velasquez is incredibly proud of his Latino background because of its rich culture, strong sense of community and connection to his parents. “My parents are my biggest inspiration. They sacrificed so much to ensure my siblings and I could succeed, leaving behind the comfort of their home and family in Peru to give us better opportunities,” Velasquez said. “Their hard work and dedication motivate me every day. Everything I do is to honor their sacrifices and show them that their efforts weren’t wasted. I owe all my success to them.”

Velasquez began his career at NASA in 2021 as an intern through the Pathways Internship Program while he was studying aerospace engineering at Rutgers University in New Brunswick, New Jersey. Through that program, he learned about eVTOL modeling software called NASA Design and Analysis of Rotorcraft to create a help guide for other NASA engineers to reference when they worked with the software.

At the same time, he is also a staff sergeant in the U.S Army Reserves and responsible for overseeing the training and development of junior soldiers during monthly assemblies. He plans, creates, and presents classes for soldiers to stay up-to-date and refine their skills while supervising practical exercises, after action reviews, and gathering lessons learned during trainings.

“This job is different than what I do day-to-day at NASA, but it has helped me become a more outspoken individual,” he said. “Being able to converse with a variety of people and be able to do it well is a skill that I acquired and refined while serving my country.”

Velasquez said he never imagined working for NASA as it was something he had only seen in movies and on television, but he is so proud to be working for the agency after all the hard work and sacrifices he made that lead him to this point. “I am incredibly proud to work every day with some of the most motivated and dedicated individuals in the industry.”

Read this story in English here.

Nacido y criado en Perú, Daniel Velásquez se estableció en los Estados Unidos cuando tenía 10 años. Aunque esa decisión fue una gran transición para su familia, también le creó muchas oportunidades. Ahora Velásquez es ingeniero de operaciones del proyecto Pathfinders de Movilidad Aérea de la NASA en el Centro de Investigación de Vuelo Armstrong de la NASA en Edwards, California.

Velásquez desarrolla ensayos de vuelo para aeronaves eléctricas de despegue y aterrizaje vertical (eVTOL, por sus siglas en inglés), poniendo a prueba específicamente su rendimiento durante varias fases del vuelo, como el rodaje, el despegue, el crucero, la aproximación y el aterrizaje. Se interesó en el centro Armstrong de la NASA debido a su legado en el avance de la investigación de vuelo y a su contribución al programa del Transbordador Espacial.

“Formar parte de un centro con una historia tan rica en el apoyo a las misiones espaciales y la aeronáutica avanzada fue una motivación importante para mí,” dice Velásquez. “Uno de los mayores hitos de mi carrera ha sido la oportunidad de conocer (virtualmente) y colaborar con un astronauta en un posible proyecto de la NASA.”

Velásquez está increíblemente orgulloso de su origen latino por su rica cultura, su fuerte sentido de comunidad y la conexión a sus padres. “Mis padres son mi mayor inspiración. Sacrificaron mucho para asegurarse de que mis hermanos y yo pudiéramos tener éxito, dejando atrás la comodidad de su hogar y su familia en Perú para darnos mejores oportunidades,” dice Velásquez. “Su esfuerzo y dedicación me motivan cada día. Todo lo que hago es para honrar sus sacrificios y demostrarles que sus esfuerzos no fueron un vano. Todo mi éxito se lo debo a ellos.”

Velásquez comenzó su carrera en la NASA en 2021 como un pasante en el Programa de Pasantías Pathways mientras estudiaba ingeniería aeroespacial en la Universidad Rutgers en New Brunswick, New Jersey. A través de ese programa, el aprendió sobre un software de modelado eVTOL que se llama Diseño y Análisis de Aeronaves de Alas Giratorias de la NASA y creó una guía de ayuda que otros ingenieros de la NASA pudieran consultar cuando trabajaban con el software.

Al mismo tiempo, también es un sargento primero de la Reserva del Ejército de EE. UU. y es responsable de supervisar el entrenamiento y el desarrollo de los soldados subalternos durante las reuniones mensuales. Planifica, crea y presenta clases para que los soldados se mantengan al día y refinen sus habilidades, a la vez que supervisa los ejercicios prácticos, las revisiones posteriores de acción y recopila lecciones aprendidas durante los entrenamientos.

24 Min Read The Marshall Star for October 16, 2024 Liftoff! NASA’s Europa Clipper Sails Toward Ocean Moon of Jupiter

NASA’s Europa Clipper has embarked on its long voyage to Jupiter, where it will investigate Europa, a moon with an enormous subsurface ocean that may have conditions to support life. The spacecraft launched at 11:06 a.m. CDT on Oct. 14 aboard a SpaceX Falcon Heavy rocket from Launch Pad 39A at NASA’s Kennedy Space Center.

A SpaceX Falcon Heavy rocket carrying NASA’s Europa Clipper spacecraft lifts off from Launch Complex 39A at the agency’s Kennedy Space Center at 11:06 a.m. CDT on Oct. 14. After launch, the spacecraft plans to fly by Mars in February 2025, then back by Earth in December 2026, using the gravity of each planet to increase its momentum. With help of these “gravity assists,” Europa Clipper will achieve the velocity needed to reach Jupiter in April 2030.Credit: NASA/Kim Shiflett

The largest spacecraft NASA ever built for a mission headed to another planet, Europa Clipper also is the first NASA mission dedicated to studying an ocean world beyond Earth. The spacecraft will travel 1.8 billion miles on a trajectory that will leverage the power of gravity assists, first to Mars in four months and then back to Earth for another gravity assist flyby in 2026. After it begins orbiting Jupiter in April 2030, the spacecraft will fly past Europa 49 times.

“Congratulations to our Europa Clipper team for beginning the first journey to an ocean world beyond Earth,” said NASA Administrator Bill Nelson. “NASA leads the world in exploration and discovery, and the Europa Clipper mission is no different. By exploring the unknown, Europa Clipper will help us better understand whether there is the potential for life not just within our solar system, but among the billions of moons and planets beyond our Sun.”

Approximately five minutes after liftoff, the rocket’s second stage fired up and the payload fairing, or the rocket’s nose cone, opened to reveal Europa Clipper. About an hour after launch, the spacecraft separated from the rocket. Ground controllers received a signal soon after, and two-way communication was established at 12:13 p.m. with NASA’s Deep Space Network facility in Canberra, Australia. Mission teams celebrated as initial telemetry reports showed Europa Clipper is in good health and operating as expected.

“We could not be more excited for the incredible and unprecedented science NASA’s Europa Clipper mission will deliver in the generations to come,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters. “Everything in NASA science is interconnected, and Europa Clipper’s scientific discoveries will build upon the legacy that our other missions exploring Jupiter – including Juno, Galileo, and Voyager – created in our search for habitable worlds beyond our home planet.”

The main goal of the mission is to determine whether Europa has conditions that could support life. Europa is about the size of our own Moon, but its interior is different. Information from NASA’s Galileo mission in the 1990s showed strong evidence that under Europa’s ice lies an enormous, salty ocean with more water than all of Earth’s oceans combined. Scientists also have found evidence that Europa may host organic compounds and energy sources under its surface.

If the mission determines Europa is habitable, it may mean there are more habitable worlds in our solar system and beyond than imagined.

“We’re ecstatic to send Europa Clipper on its way to explore a potentially habitable ocean world, thanks to our colleagues and partners who’ve worked so hard to get us to this day,” said Laurie Leshin, director, NASA’s Jet Propulsion Laboratory (JPL). “Europa Clipper will undoubtedly deliver mind-blowing science. While always bittersweet to send something we’ve labored over for years off on its long journey, we know this remarkable team and spacecraft will expand our knowledge of our solar system and inspire future exploration.”

In 2031, the spacecraft will begin conducting its science-dedicated flybys of Europa. Coming as close as 16 miles to the surface, Europa Clipper is equipped with nine science instruments and a gravity experiment, including an ice-penetrating radar, cameras, and a thermal instrument to look for areas of warmer ice and any recent eruptions of water. As the most sophisticated suite of science instruments NASA has ever sent to Jupiter, they will work in concert to learn more about the moon’s icy shell, thin atmosphere, and deep interior.

To power those instruments in the faint sunlight that reaches Jupiter, Europa Clipper also carries the largest solar arrays NASA has ever used for an interplanetary mission. With arrays extended, the spacecraft spans 100 feet from end to end. With propellant loaded, it weighs about 13,000 pounds.

In all, more than 4,000 people have contributed to Europa Clipper mission since it was formally approved in 2015.

“As Europa Clipper embarks on its journey, I’ll be thinking about the countless hours of dedication, innovation, and teamwork that made this moment possible,” said Jordan Evans, project manager, JPL. “This launch isn’t just the next chapter in our exploration of the solar system; it’s a leap toward uncovering the mysteries of another ocean world, driven by our shared curiosity and continued search to answer the question, ‘are we alone?’”

Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.

Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center, Marshall Space Flight Center, and Langley Research Center. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission.

NASA’s Launch Services Program, based at NASA Kennedy, managed the launch service for the Europa Clipper spacecraft.

Black Hole Destroys Star, Goes After Another, NASA Missions Find

NASA’s Chandra X-ray Observatory and other telescopes have identified a supermassive black hole that has torn apart one star and is now using that stellar wreckage to pummel another star or smaller black hole, as described in our latest press release. This research helps connect two cosmic mysteries and provides information about the environment around some of the bigger types of black holes.

This artist’s illustration shows a disk of material (red, orange, and yellow) that was created after a supermassive black hole (depicted on the right) tore apart a star through intense tidal forces.X-ray: NASA/CXC/Queen’s Univ. Belfast/M. Nicholl et al.; Optical/IR: PanSTARRS, NSF/Legacy Survey/SDSS; Illustration: Soheb Mandhai / The Astro Phoenix; Image Processing: NASA/CXC/SAO/N. Wolk

This artist’s illustration shows a disk of material (red, orange, and yellow) that was created after a supermassive black hole (depicted on the right) tore apart a star through intense tidal forces. Over the course of a few years, this disk expanded outward until it intersected with another object – either a star or a small black hole – that is also in orbit around the giant black hole. Each time this object crashes into the disk, it sends out a burst of X-rays detected by Chandra. The inset shows Chandra data (purple) and an optical image of the source from Pan-STARRS (red, green, and blue).

In 2019, an optical telescope in California noticed a burst of light that astronomers later categorized as a “tidal disruption event”, or TDE. These are cases where black holes tear stars apart if they get too close through their powerful tidal forces. Astronomers gave this TDE the name of AT2019qiz.

Meanwhile, scientists were also tracking instances of another type of cosmic phenomena occasionally observed across the Universe. These were brief and regular bursts of X-rays that were near supermassive black holes. Astronomers named these events “quasi-periodic eruptions,” or QPEs.

This latest study gives scientists evidence that TDEs and QPEs are likely connected. The researchers think that QPEs arise when an object smashes into the disk left behind after the TDE. While there may be other explanations, the authors of the study propose this is the source of at least some QPEs.

In 2023, astronomers used both Chandra and Hubble to simultaneously study the debris left behind after the tidal disruption had ended. The Chandra data were obtained during three different observations, each separated by about 4 to 5 hours. The total exposure of about 14 hours of Chandra time revealed only a weak signal in the first and last chunk, but a very strong signal in the middle observation.

From there, the researchers used NASA’s Neutron Star Interior Composition Explorer (NICER) to look frequently at AT2019qiz for repeated X-ray bursts. The NICER data showed that AT2019qiz erupts roughly every 48 hours. Observations from NASA’s Neil Gehrels Swift Observatory and India’s AstroSat telescope cemented the finding.

The ultraviolet data from Hubble, obtained at the same time as the Chandra observations, allowed the scientists to determine the size of the disk around the supermassive black hole. They found that the disk had become large enough that if any object was orbiting the black hole and took about a week or less to complete an orbit, it would collide with the disk and cause eruptions.

This result has implications for searching for more quasi-periodic eruptions associated with tidal disruptions. Finding more of these would allow astronomers to measure the prevalence and distances of objects in close orbits around supermassive black holes. Some of these may be excellent targets for the planned future gravitational wave observatories.

The paper describing these results appears in the Oct. 9 issue of the journal Nature. The first author of the paper is Matt Nicholl of Queen’s University Belfast in Ireland.

Revealing the Hidden Universe with Full-shell X-ray Optics at Marshall

The study of X-ray emission from astronomical objects reveals secrets about the universe at the largest and smallest spatial scales. Celestial X-rays are produced by black holes consuming nearby stars, emitted by the million-degree gas that traces the structure between galaxies, and can be used to predict whether stars may be able to host planets hospitable to life. X-ray observations have shown that most of the visible matter in the universe exists as hot gas between galaxies and have conclusively demonstrated that the presence of “dark matter” is needed to explain galaxy cluster dynamics, that dark matter dominates the mass of galaxy clusters, and that it governs the expansion of the cosmos.

The X-ray image from the Chandra X-ray Observatory (blue and white), reveals exquisite details in the central ring structures and gas flowing out of the polar jets. Optical light from the Hubble Space Telescope (purple) shows foreground and background stars as pinpoints of light. Infrared light from the Spitzer Space Telescope (pink) traces cooler gas in the nebula. Finally, magnetic field direction derived from X-ray polarization observed by the Imaging X-ray Polarimetry Explorer is shown as orange lines.Magnetic field lines: NASA/Bucciantini et al; X-ray: NASA/CXC/SAO; Optical: NASA/STScI; Infrared: NASA-JPL-Caltech

X-ray observations also enable us to probe mysteries of the universe on the smallest scales. X-ray observations of compact objects such as white dwarfs, neutron stars, and black holes allow us to use the universe as a physics laboratory to study conditions that are orders of magnitude more extreme in terms of density, pressure, temperature, and magnetic field strength than anything that can be produced on Earth. In this astrophysical laboratory, researchers expect to reveal new physics at the subatomic scale by conducting investigations such as probing the neutron star equation of state and testing quantum electrodynamics with observations of neutron star atmospheres.

At NASA’s Marshall Space Flight Center, a team of scientists and engineers is building, testing, and flying innovative optics that bring the universe’s X-ray mysteries into sharper focus.

Unlike optical telescopes that create images by reflecting or refracting light at near-90-degree angles (normal incidence), focusing X-ray optics must be designed to reflect light at very small angles (grazing incidence). At normal incidence, X-rays are either absorbed by the surface of a mirror or penetrate it entirely. However, at grazing angles of incidence, X-rays reflect very efficiently due to an effect called total external reflection. In grazing incidence, X-rays reflect off the surface of a mirror like rocks skipping on the surface of a pond.

A classic design for astronomical grazing incidence optics is the Wolter-I prescription, which consists of two reflecting surfaces, a parabola and hyperbola (see figure below). This optical prescription is revolved around the optical axis to produce a full-shell mirror (i.e., the mirror spans the full circumference) that resembles a gently tapered cone. To increase the light collecting area, multiple mirror shells with incrementally larger diameters and a common focus are fabricated and nested concentrically to comprise a mirror module assembly (MMA).

Focusing optics are critical to studying the X-ray universe because, in contrast to other optical systems like collimators or coded masks, they produce high signal-to-noise images with low background noise. Two key metrics that characterize the performance of X-ray optics are angular resolution, which is the ability of an optical system to discriminate between closely spaced objects, and effective area, which is the light collecting area of the telescope, typically quoted in units of cm2. Angular resolution is typically measured as the half-power diameter (HPD) of a focused spot in units of arcseconds. The HPD encircles half of the incident photons in a focused spot and measures the sharpness of the final image; a smaller number is better.

Parallel rays of light enter from the left, reflect twice off the reflective inside surface of the shell (first off the parabolic segment and then off the hyperbolic segment), and converge at the focal plane.NASA

Marshall has been building and flying lightweight, full-shell, focusing X-ray optics for over three decades, always meeting or exceeding angular resolution and effective area requirements. Marshall utilizes an electroformed nickel replication technique to make these thin full-shell X-ray optics from nickel alloy.

X-ray optics development at Marshall began in the early 1990s with the fabrication of optics to support NASA’s Advanced X-ray Astrophysics Facility (AXAF-S) and then continued via the Constellation-X technology development programs. In 2001, Marshall launched a balloon payload that included two modules each with three mirrors, which produced the first focused hard X-ray images of an astrophysical source by imaging Cygnus X-1, GRS 1915, and the Crab Nebula. This initial effort resulted in several follow-up missions over the next 12 years and became known as the High Energy Replicated Optics (HERO) balloon program.

In 2012, the first of four sounding rocket flights of the Focusing Optics X-ray Solar Imager (FOXSI) flew with Marshall optics onboard, producing the first focused images of the Sun at energies greater than 5 keV. In 2019 the Astronomical Roentgen Telescope X-ray Concentrator (ART-XC) instrument on the Spectr-Roentgen-Gamma Mission launched with seven Marshall-fabricated X-ray MMAs, each containing 28 mirror shells. ART-XC is currently mapping the sky in the 4-30 keV hard X-ray energy range, studying exotic objects like neutron stars in our own galaxy as well as active galactic nuclei, which are spread across the visible universe. In 2021, the Imaging X-ray Polarimetry Explorer (IXPE), flew and is now performing extraordinary science with a Marshall-led team using three, 24-shell MMAs that were fabricated and calibrated in-house.

Most recently, in 2024, the fourth FOXSI sounding rocket campaign launched with a high-resolution Marshall MMA. The optics achieved 9.5 arcsecond HPD angular resolution during pre-flight test with an expected 7 arcsecond HPD in gravity-free flight, making this the highest angular resolution flight observation made with a nickel-replicated X-ray optic. Currently Marshall is fabricating an MMA for the Rocket Experiment Demonstration of a Soft X-ray (REDSoX) polarimeter, a sounding rocket mission that will fly a novel soft X-ray polarimeter instrument to observe active galactic nuclei. The REDSoX MMA optic will be 444 mm in diameter, which will make it the largest MMA ever produced by MSFC and the second largest replicated nickel X-ray optic in the world.

The ultimate performance of an X-ray optic is determined by errors in the shape, position, and roughness of the optical surface. To push the performance of X-ray optics toward even higher angular resolution and achieve more ambitious science goals, Marshall is currently engaged in a fundamental research and development effort to improve all aspects of full-shell optics fabrication.

Scientists Wayne Baumgartner, left, crouched, and Nick Thomas, left, standing, calibrate an IXPE MMA in the Marshall 100 m Beamline. Scientist Stephen Bongiorno, right, applies epoxy to an IXPE shell during MMA assembly.NASA

Given that these optics are made with the electroformed nickel replication technique, the fabrication process begins with creation of a replication master, called the mandrel, which is a negative of the desired optical surface. First, the mandrel is figured and polished to specification, then a thin layer of nickel alloy is electroformed onto the mandrel surface. Next, the nickel alloy layer is removed to produce a replicated optical shell, and finally the thin shell is attached to a stiff holding structure for use.

Each step in this process imparts some degree of error into the final replicated shell. Research and development efforts at Marshall are currently concentrating on reducing distortion induced during the electroforming metal deposition and release steps. Electroforming-induced distortion is caused by material stress built into the electroformed material as it deposits onto the mandrel. Decreasing release-induced distortion is a matter of reducing adhesion strength between the shell and mandrel, increasing strength of the shell material to prevent yielding, and reducing point defects in the release layer.

Additionally, verifying the performance of these advanced optics requires world-class test facilities. The basic premise of testing an optic designed for X-ray astrophysics is to place a small, bright X-ray source far away from the optic. If the angular size of the source, as viewed from the optic, is smaller than the angular resolution of the optic, the source is effectively simulating X-ray starlight. Due to the absorption of X-rays by air, the entire test facility light path must be placed inside a vacuum chamber.

At the center, a group of scientists and engineers operate the Marshall 100-meter X-ray beamline, a world-class end-to-end test facility for flight and laboratory X-ray optics, instruments, and telescopes. As per the name, it consists of a 100-meter-long vacuum tube with an 8-meter-long, 3-meter-diameter instrument chamber and a variety of X-ray sources ranging from 0.25 – 114 keV. Across the street sits the X-Ray and Cryogenic Facility (XRCF), a 527-meter-long beamline with an 18-meter-long, 6-meter-diameter instrument chamber. These facilities are available for the scientific community to use and highlight the comprehensive optics development and test capability that Marshall is known for.

Within the X-ray astrophysics community there exist a variety of angular resolution and effective area needs for focusing optics. Given its storied history in X-ray optics, Marshall is uniquely poised to fulfill requirements for large or small, medium- or high-angular-resolution X-ray optics. To help guide technology development, the astrophysics community convenes once per decade to produce a decadal survey. The need for high-angular-resolution and high-throughput X-ray optics is strongly endorsed by the National Academies of Sciences, Engineering, and Medicine report, Pathways to Discovery in Astronomy and Astrophysics for the 2020s.In pursuit of this goal, Marshall is continuing to advance the state of the art in full-shell optics. This work will enable the extraordinary mysteries of the X-ray universe to be revealed.

Hubble, New Horizons Team Up for a Simultaneous Look at Uranus

NASA’s Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study like types of planets around other stars.

Astronomers used Uranus as a proxy for similar planets beyond our solar system, known as exoplanets, comparing high-resolution images from Hubble to the more-distant view from New Horizons. This combined perspective will help scientists learn more about what to expect while imaging planets around other stars with future telescopes.

“While we expected Uranus to appear differently in each filter of the observations, we found that Uranus was actually dimmer than predicted in the New Horizons data taken from a different viewpoint,” said lead author Samantha Hasler of the Massachusetts Institute of Technology in Cambridge and New Horizons science team collaborator.

Direct imaging of exoplanets is a key technique for learning about their potential habitability, and offers new clues to the origin and formation of our own solar system. Astronomers use both direct imaging and spectroscopy to collect light from the observed planet and compare its brightness at different wavelengths. However, imaging exoplanets is a notoriously difficult process because they’re so far away. Their images are mere pinpoints and so are not as detailed as the close-up views that we have of worlds orbiting our Sun. Researchers can also only directly image exoplanets at “partial phases,” when only a portion of the planet is illuminated by their star as seen from Earth.

Uranus was an ideal target as a test for understanding future distant observations of exoplanets by other telescopes for a few reasons. First, many known exoplanets are also gas giants similar in nature. Also, at the time of the observations, New Horizons was on the far side of Uranus, 6.5 billion miles away, allowing its twilight crescent to be studied – something that cannot be done from Earth. At that distance, the New Horizons view of the planet was just several pixels in its color camera, called the Multispectral Visible Imaging Camera.

On the other hand, Hubble, with its high resolution, and in its low-Earth orbit 1.7 billion miles away from Uranus, was able to see atmospheric features such as clouds and storms on the day side of the gaseous world.

“Uranus appears as just a small dot on the New Horizons observations, similar to the dots seen of directly imaged exoplanets from observatories like Webb or ground-based observatories,” Hasler said. “Hubble provides context for what the atmosphere is doing when it was observed with New Horizons.”

The gas giant planets in our solar system have dynamic and variable atmospheres with changing cloud cover. How common is this among exoplanets? By knowing the details of what the clouds on Uranus looked like from Hubble, researchers can verify what is interpreted from the New Horizons data. In the case of Uranus, both Hubble and New Horizons saw that the brightness did not vary as the planet rotated, which indicates that the cloud features were not changing with the planet’s rotation.

In this image, two three-dimensional shapes, top, of Uranus are compared to the actual views of the planet from NASA’s Hubble Space Telescope, bottom left, and NASA’s New Horizon’s spacecraft, bottom right. Comparing high-resolution images from Hubble to the smaller view from New Horizons offers a combined perspective that will help researchers learn more about what to expect while imaging planets around other stars with future observatories. NASA, ESA, STScI, Samantha Hasler (MIT), Amy Simon (NASA-GSFC), New Horizons Planetary Science Theme Team; Image Processing: Joseph DePasquale (STScI), Joseph Olmsted (STScI)

However, the importance of the detection by New Horizons has to do with how the planet reflects light at a different phase than what Hubble, or other observatories on or near Earth, can see. New Horizons showed that exoplanets may be dimmer than predicted at partial and high phase angles, and that the atmosphere reflects light differently at partial phase.

NASA has two major upcoming observatories in the works to advance studies of exoplanet atmospheres and potential habitability.

“These landmark New Horizons studies of Uranus from a vantage point unobservable by any other means add to the mission’s treasure trove of new scientific knowledge, and have, like many other datasets obtained in the mission, yielded surprising new insights into the worlds of our solar system,” added New Horizons principal investigator Alan Stern of the Southwest Research Institute.

NASA’s upcoming Nancy Grace Roman Space Telescope, set to launch by 2027, will use a coronagraph to block out a star’s light to directly see gas giant exoplanets. NASA’s Habitable Worlds Observatory, in an early planning phase, will be the first telescope designed specifically to search for atmospheric biosignatures on Earth-sized, rocky planets orbiting other stars.

“Studying how known benchmarks like Uranus appear in distant imaging can help us have more robust expectations when preparing for these future missions,” concluded Hasler. “And that will be critical to our success.”

Launched in January 2006, New Horizons made the historic flyby of Pluto and its moons in July 2015, before giving humankind its first close-up look at one of these planetary building block and Kuiper Belt object, Arrokoth, in January 2019. New Horizons is now in its second extended mission, studying distant Kuiper Belt objects, characterizing the outer heliosphere of the Sun, and making important astrophysical observations from its unmatched vantage point in distant regions of the solar system.

The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

The Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, built and operates the New Horizons spacecraft and manages the mission for NASA’s Science Mission Directorate. Southwest Research Institute, based in San Antonio and Boulder, Colorado, directs the mission via Principal Investigator Alan Stern and leads the science team, payload operations and encounter science planning. New Horizons is part of NASA’s New Frontiers program, managed by NASA’s Marshall Space Flight Center.

NASA is announcing the relaunch of the NASA Acquisition Innovation Launchpad (NAIL), a framework to drive innovation and modernize acquisition processes across the agency, after piloting the program for a year.

NASA spends approximately $21 billion or 85% of its budget on acquiring goods and services. Managed by NASA’s Office of Procurement, the NAIL was established to identify ways to manage risk-taking and encourage innovation through the submission, review, and approval of ideas from anyone who engages in the acquisition process. 

Since launching last year, the goal of the NAIL has been to build an innovation-focused culture that can produce ideas from team members in the Office of Procurement or across the agency, as well as from industry.

“The success of the NAIL inaugural year has laid a strong foundation for the future,” said Karla Smith Jackson, deputy chief acquisition officer and assistant administrator for the Office of Procurement.

Over the past year, the NAIL has achieved numerous milestones, allowing NASA to approach various procurement challenges and implement diverse solutions. Key accomplishments include improving procurement processes and technological automations and developing an industry feedback forum. The program update will leverage industry’s feedback to continue fostering innovative solutions and optimize the agency’s procurement efforts.

As NASA’s Office of Procurement embarks on fiscal year 2025, the NAIL relaunch will use information from the program’s pilot year to focus on the following priorities:

• Providing additional engagement opportunities for the agency’s network of innovators
• Enhancing the framework to improve internal outcomes for the agency
• Promoting procurement success stories 
• Investing in talent and technology

“We are incredibly proud of the program’s achievements and are even more excited about the opportunities ahead with the relaunch,” said Kameke Mitchell, NAIL chair and director for the Procurement Strategic Operations Division. “We encourage everyone to get involved and make fiscal year 2025 a standout year for innovation.”

In addition to programmatic updates, NAIL’s program manager, Brittney Chappell, will lead new engagements and framework enhancements moving forward.

“I am thrilled to step into this role and lead the program, using everything our team has learned from the last year,” said Chappell. “Together with internal and external stakeholders, we will turn bold ideas into impactful solutions that drive real change.”

4 Min Read NASA to Embrace Commercial Sector, Fly Out Legacy Relay Fleet  An artist's concept of commercial and NASA space relays. Credits: NASA/Morgan Johnson

NASA is one step closer on its transition to using commercially owned and operated satellite communications services to provide future near-Earth space missions with increased service coverage, availability, and accelerated science and data delivery.     

As of Friday, Nov. 8, the agency’s legacy TDRS (Tracking and Data Relay Satellite) system, as part of the Near Space Network, will support only existing missions while new missions will be supported by future commercial services.    

“There have been tremendous advancements in commercial innovation since NASA launched its first TDRS satellite more than 40 years ago,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN (Space Communications and Navigation) program. “TDRS will continue to provide critical support for at least the next decade, but now is the time to embrace commercial services that could enhance science objectives, expand experimentation, and ultimately provide greater opportunities for discovery.”    

TDRS will continue to provide critical support for at least the next decade, but now is the time to embrace commercial services."

Deputy Associate Administrator for NASA’s SCaN

Just as NASA has adopted commercial crew, commercial landers, and commercial transport services, the Near Space Network, managed by NASA’s SCaN, will leverage private industry’s vast investment in the Earth-based satellite communications market, which includes communications on airplanes, ships, satellite dish television, and more. Now, industry is developing a new space-based market for these services, where NASA plans to become one of many customers, bolstering the domestic space industry.    

NASA’s Communications Services Project is working with industry through funded Space Act Agreements to develop and demonstrate commercial satellite communications services that meet the agency’s mission needs, and the needs of other potential users.   

In 2022, NASA provided $278.5 million in funding to six domestic partners so they could develop and demonstrate space relay communication capabilities.  

• Inmarsat Government Inc.  
• Kuiper Government Solutions (KGS) LLC   
• SES Government Solutions  
• Space Exploration Technologies (SpaceX)  
• Telesat U.S. Services LLC  
• Viasat Incorporated

A successful space-based commercial service demonstration would encompass end-to-end testing with a user spacecraft for one or more of the following use cases: launch support, launch and early operations phase, low and high data rate routine missions, terrestrial support, and contingency services. Once a demonstration has been completed, it is expected that the commercial company would be able to offer their services to government and commercial users.    

NASA also is formulating non-reimbursable Space Act Agreements with members of industry to exchange capability information as a means of growing the domestic satellite communications market. The Communications Services Project currently is partnered with Kepler Communications US Inc. through a non-reimbursable Space Act Agreement.    

As the agency and the aerospace community expand their exploration efforts and increase mission complexity, the ability to communicate science, tracking, and telemetry data to and from space quickly and securely will become more critical than ever before. The goal is to validate and deliver space-based commercial communications services to the Near Space Network by 2031, to support future NASA missions.   

NASA’s Tracking and Data Relay System  

While TDRS will not be accepting new missions, it won’t be retiring immediately. Current TDRS users, like the International Space Station, Hubble Space Telescope, and many other Earth- and universe-observing missions, will still rely on TDRS until the mid-2030s. Each TDRS spacecraft’s retirement will be driven by individual health factors, as the seven active TDRS satellites are expected to decline at variable rates.

The TDRS fleet began in 1983 and consists of three generations of satellites, launching over the course of 40 years. Each successive generation of TDRS improved upon the previous model, with additional radio frequency band support and increased automation.    

The first TDRS was designed for a mission life of 10 years, but lasted 26 years before it was decommissioned in 2009. The last in the third generation – TDRS-13 –was launched Aug. 18, 2017.   

The TDRS constellation has been a workhorse for the agency, enabling significant data transfer and discoveries.”   

DAve Israel

Near Space Network Chief Architect

“Each astronaut conversation from the International Space Station, every picture you’ve seen from Hubble Space Telescope, Nobel Prize-winning science data from the COBE satellite, and much more has flowed through TDRS,” said Dave Israel, Near Space Network chief architect. “The TDRS constellation has been a workhorse for the agency, enabling significant data transfer and discoveries.”

The Near Space Network and the Communications Services Project are funded by NASA’s SCaN (Space Communications and Navigation) program office at NASA Headquarters in Washington. The network is operated out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the Communications Services Project is managed out of NASA’s Glenn Research Center in Cleveland.

Sols 4334-4335: Planning with Popsicles — A Clipper Celebration! This image was taken by Left Navigation Camera aboard NASA’s Mars rover Curiosity on Sol 4329 — Martian day 4,329 of the Mars Science Laboratory mission — on Oct. 10, 2024, at 05:35:08 UTC. NASA/JPL-Caltech

Earth planning date: Monday, Oct. 14, 2024

Today was an unusually exciting day during tactical planning on the Curiosity mission because it intersected with a momentous event in space exploration: the launch of Europa Clipper from Kennedy Space Center. Even though the launch window occurred right in the middle of our morning planning meetings, at 9:06 a.m. PDT to be specific, today’s Tactical Uplink Lead and Science Operations Working Group Chair agreed it would be OK for the entire tactical team to take a 15-minute pause to turn on NASA TV and watch the launch together. Down the hall the Perseverance rover tactical team had decided the same, and for a few moments, the two teams paused their planning and watched together in anticipation as the countdown ticked down to T-0. Many of my close friends and co-workers had worked for years — some for decades — to make this mission a reality, and it was amazing to watch the enormous rocket carrying the Clipper spacecraft leap off the pad knowing how hard it was to get to this point. I cannot wait for the mission’s discoveries once it reaches Jupiter’s watery moon Europa!

In true JPL tradition, we of course had to commemorate the event with some sweet frozen treats on-lab. Back when Curiosity landed, we had a full fridge of ice cream that was kept stocked for the first 90 sols of the mission. (Eating ice cream cones at 2 in the morning is a core memory of mine from those early days in our mission.) Today, in a clever nod to Europa’s icy surface, we celebrated with some even icier sweets: fruit and coffee popsicles to anyone on-lab. I chose coffee of course; the caffeine was great to help me get through a busy day of planning for Curiosity!

On Mars, things with our rover are going well. We completed our mega ~50-meter drive (about 164 feet) over the weekend, which took Curiosity further north along the western side of Gediz Vallis channel. Our plan today is a “touch and go,” which means we’ll do contact science with APXS and MAHLI on a block in front of us named “Dollar Lake,” some remote sensing, including ChemCam LIBS of a target named “Cape Horn” and a couple Mastcam mosaics, followed by a drive to the north. We’ll continue to follow the western side of Gediz Vallis channel as we descend slightly down Mount Sharp, until we reach a location where we are able to head west towards a more easily traversable valley, and then restart our ascent.

What a fun day of planning today. Congratulations to everyone involved helping Europa Clipper reach this incredible milestone, and go Clipper go!

Coral reefs cover only 1% of the ocean floor, but support an estimated 25% of all marine life in the ocean, earning them the moniker ‘rainforest of the sea.’ They also play a critical role for coastal communities; preventing coastal erosion, protecting coastlines from hurricane damage, and generating $36 billion in annual income worldwide.

We asked Juan Torres-Pérez, a research scientist and coral reef expert at NASA Ames Research Center, about the science behind coral reefs, and the role they play in both marine ecosystems and human communities.

What is the difference between a reef, coral, and a coral reef?

Reef

Reefs are ridge-like structures, either natural or artificial. “A reef by definition is a structure that provides some relief above the ocean floor,” Torres-Pérez said. “It could be something man-made: you can pile a bunch of car tires, and then they get colonized by different organisms. Or it could be natural: a small hill on top of the ocean floor in which the primary framework is a rock.”

Corals

Corals are animals from the phylum Cnidaria, typically found along tropical coastlines. They comprise hundreds to thousands of living organisms called polyps, each only a few millimeters in diameter. Each polyp has its own body and a mouth with stinging tentacles to capture food such as plankton and small fish. The polyps grow together until they form a colony, and it is this colony that we recognize as a coral. There are two types of coral: hard corals and soft corals. Hard corals, also known as stony corals or more formally as Scleractinians, secrete calcium carbonate to form a hard skeleton; it is this type of coral that form a coral reefs. Soft corals, also known as Alcyonacea, are fleshy and bendable, often resembling trees or fans.

The colorful appearance of corals comes from the microscopic algae that live inside coral cells, called zooxanthellae. These algae perform photosynthesis, bringing vital food and nutrients to the corals. “The majority of the products from photosynthesis, about 80 to 90%, pass on to the coral, and then the coral uses those for its own metabolism,” said Torres-Pérez. “This is why corals are usually found in shallow waters: because these organisms need the sunlight to photosynthesize.”

Coral Reefs

A coral reef is a term used to describe the collective structure of hard corals that help shape a coral reef ecosystem. “A coral reef is a reef whose main structure is made by living organisms, in this case corals,” said Torres-Pérez. “A coral reef will always be a reef, but not all reefs are coral reefs.” The largest coral reef in the world is Australia’s Great Barrier Reef, which is over 1,000 miles long and covers around 133,000 square miles.

Why are coral reefs important?

Healthy coral reefs play a crucial role in providing coastal protection, habitats for marine life, and even key ingredients for potential new medicines.

“Coral reef ecosystems provide habitat for thousands of species, from unicellular organisms like bacteria or some phytoplankton communities, to large organisms like sharks, groupers or snappers, and reptiles like sea turtles,” Torres-Pérez said.

Corals act as a protective barrier during big storm events such as typhoons or hurricanes and have proven to be 97% effective in preventing damage to the natural and built environment. As coral reefs have been damaged in recent decades, coastal flooding and erosion have increased, causing significant damage to coastal communities.

Many communities depend on coral reefs as a resource to sustain their livelihoods. “These are critical ecosystems, not only in terms of the whole biodiversity of the planet but because they also provide sustenance for millions of people, especially in island nations,” Torres-Pérez said. Coral reefs also support fisheries (fish caught for commercial, recreational, or subsistence purposes), recreational activities, and educational purposes.

Scientists have been exploring coral as a new ingredient source for some medicines. They have discovered that a chemical from coral can be extracted to create antibiotics that are effective against bacteria resistant to other types of antibiotics. These ingredients are replicated in a lab, eliminating the need to continuously harvest and harm corals.

What are some current threats to coral reefs?

According to a 2020 report produced by the Global Coral Reef Monitoring Network (GCRMN), 14% of the world’s coral reefs have been lost since 2009. In the wake of the 2023-2024 global coral bleaching event, that number is expected to increase.

Coral bleaching is caused by increasing ocean temperatures. As water temperatures rise, it causes corals to expel their zooxanthellae, leaving behind a bone-white shell and depriving the coral of its main food source. “Eventually what happens is that the coral is too weak to compete with other organisms, like filamentous algae, that can overgrow the coral and eventually kill the whole colony,” said Torres-Pérez.

Other threats to coral reefs come from human activity, such as pollution or physical damage. “Increases in sedimentation from poor land management get deposited into the reefs,” said Torres-Pérez, citing urban stormwater runoff and deforestation as two examples of sedimentation. Coral sedimentation is the deposition and accumulation of sediments, like fine sands or mud, on a reef. This clouds the waters, blocking critical sunlight and reducing the ability of zooxanthellae to photosynthesize.

Another human-caused threat to corals is eutrophication, the unnatural increase of nutrients in the water. “Eutrophication provides grounds for the development of filamentous algae, which grows much faster than corals,” said Torres-Pérez. Some of these excess nutrients in the water come from sewage released into coastal waters or runoff of agricultural fertilizers into the ocean. The algae feed off the excess nutrients and grow into massive blooms, which suppress the growth of corals.

Moreover, Torres-Pérez pointed out that human-caused physical damage to reefs can result from mechanical damage, such as ship anchors being thrown onto corals. Some fishing techniques, like deep water trawling (dragging fishing nets along the sea floor), can also damage reefs by pulling and tearing corals away from their bases. On a more individual scale, coral damage can also result from being stepped on by humans, or accumulated trash left behind by beach-goers.

What is being done to protect coral, at NASA and beyond?

Many coral reefs in the world are still unclassified, unexplored, or yet to be discovered. NASA’s NeMO-Net hopes to change that. Torres-Pérez, who is a Co-Investigator for NeMO-Net, described how the citizen science project functions like an interactive mobile video game, allowing anyone to identify corals. “Users can characterize different components of a coral reef based on 2D [and 3D] images of a coral reef,” said Torres-Pérez. “which goes into a machine learning component.” The information from these classifications is fed into a scientific model and helps NASA both classify and assess the health of coral reefs around the world. To learn more about NeMO-Net and how to get involved, check out their website.

In 2022, Torres-Pérez founded OCEANOS (Ocean Community Engagement and Awareness using NASA Earth Observations and Science for Hispanic/Latino Students), a program aimed at bringing oceanography and STEM opportunities to the next generation of Hispanic/Latino students in Puerto Rico. During the program, students build and test their own low-cost optical sensors, test data in a phytoplankton lab, replant coral reefs, and create storymap presentations of their work. “We want students to feel confident and capable to pursue STEM careers,” Torres-Pérez said, “and we want them to become agents of change in their community to share the importance of preserving the ocean.”

Outside of NASA, Torres-Pérez is an active member of the U.S. Coral Reef Task Force (USCRTF); an interagency body established in 1998 from Executive Order 13089: Coral Reef Protection that aims to preserve, protect, and restore coral reef ecosystems.

Resources to Learn More

To learn more about coral reefs and how they are monitored, Torres-Pérez recommends checking out resources from the National Oceanic and Atmospheric Administration (NOAA), which has a section on their website dedicated to corals. One notable coral reef resource from NOAA is their Coral Reef Watch website, which monitors sea surface temperatures on global and local scales. The website serves government and non-governmental agencies with their data products, which are used to monitor and predict climate impacts on coral reefs worldwide.

What's happening at the center of spiral galaxy M106?

Researchers verified that 3D micro-computed tomography scans can map the orientation of plant roots in space and used the method to demonstrate that carrots grown in actual and simulated microgravity both had random root orientation. These findings suggest that simulated microgravity offers a reliable and more affordable tool for studying plant adaptation to spaceflight.

MULTI-TROP evaluated the role of gravity and other factors on plant growth. Plant roots grow downward in response to gravity on Earth, but in random directions in microgravity, which is a challenge for developing plant growth facilities for space. Results from this investigation could help address this challenge, advancing efforts to grow plants for food and other uses on future space missions as well as improving plant cultivation on Earth.

For climate model simulations, researchers developed four parameters of electrical discharges from thunderclouds that produce visual emissions known as Blue LUminous Events or BLUEs. BLUEs are thought to affect regional atmospheric chemistry and climate. The parameters reported by this study could inform models that help test the global and regional effects of thunderstorm corona discharges, including how their geographic distribution and global occurrence rate will change as the atmosphere warms.

ASIM, an investigation from ESA (European Space Agency), studies high-altitude lightning in thunderstorms and the role it plays in Earth’s atmosphere and climate. Scientists need to understand processes occurring in Earth’s upper atmosphere to determine how lightning is connected to Earth’s climate and weather so they can develop better atmospheric models to guide weather and climate predictions.

A technique to detect sounds generated by the inner ear could be used as a non-invasive tool for monitoring changes in fluid pressure in the head during spaceflight. Increased fluid pressure in the head that occurs in microgravity can cause visual impairment and may also affect the middle and inner ear. Insight into fluid pressure changes could help scientists develop ways to protect astronauts from these effects.

The ESA and ASI investigation Acoustic Diagnostics monitored hearing function in astronauts on long-term missions using otoacoustic emissions (sounds generated by the inner ear in response to specific tones). Researchers compared these measurements before and during flight to indirectly detect changes in fluid pressure in the head. Different body position and fit of the ear probes affected results of the test and the authors note that these issues need to be addressed.

Great Lakes Science Center, home of the visitor center for NASA’s Glenn Research Center in Cleveland, hosted the final phase of NASA’s Watts on the Moon Challenge on Sept. 20. NASA astronaut Stephen Bowen attended to help acknowledge the top winners.  

NASA awarded a total of $1.5 million to two U.S. teams for their novel technology solutions addressing energy distribution, management, and storage as part of the challenge. The innovations from this challenge aim to support NASA’s Artemis missions, which will establish a long-term human presence on the Moon. 

This two-phase competition challenged U.S. innovators to develop breakthrough technologies that could enable long-duration Moon missions to advance the nation’s lunar exploration goals. 

The winning teams are: 

• First Prize ($1 million): Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from University of California, Santa Barbara , won the grand prize for their hardware solution, which featured the lowest mass and highest efficiency of all competitors.  

• Second prize ($500,000): Orbital Mining Corporation, a space technology startup in Golden, Colorado, earned the second prize for its hardware solution that also successfully completed the 48-hour test with high performance. 

Four teams were invited to refine their hardware and deliver full system prototypes in the  final stage of the competition, and three finalist teams completed their technology solutions for demonstration and assessment at NASA Glenn.
