Astronauts on the International Space Station generate their share of garbage, filling up cargo ships that then deorbit and burn up in the atmosphere. Now Sierra Space has won a contract to build a trash compactor for the space station. The device will compact space trash by 75% in volume and allow water and other gases to be extracted for reclamation. The resulting garbage blocks are easily stored and could even be used as radiation shielding on long missions.

Called the Trash Compaction and Processing System (TCPS), plans are to test it aboard the International Space Station in late 2026.

Sierra Space said this technology could be critical for the success of future space exploration — such as long-duration crewed missions to the Moon and Mars — to handle waste management, stowage, and water reclamation.

“Long-term space travel requires the efficient use of every ounce of material and every piece of equipment. Every decision made on a spacecraft can have far-reaching consequences, and waste management becomes a matter of survival and mission integrity in the vacuum of space,” said Sierra Space CEO, Tom Vice, in a press release. “We’re addressing this challenge through technological innovation and commitment to sustainability in every facet of space operations. Efficient, sustainable, and innovative waste disposal is essential for the success of crewed space exploration.”

NASA said that currently aboard the International Space Station (ISS), common trash such as food packaging, clothing, and wipes are separated into wet and dry trash bags; these bags are stored temporarily before being packed into a spent resupply vehicle, such as the Russian Progress ship or Northrup Grumman’s Cygnus vehicle. When full, these ships undock and burn up during atmospheric re-entry, taking all the trash with it.

However, for missions further out into space trash will have to be managed and disposed of by other methods, such as jettisoning the trash into space – which doesn’t sound like a very eco-friendly idea. Additionally, wet trash contains components that may not be storable for long periods between jettisoning events without endangering the crew. 

Plus, there’s currently no way for any water to be reclaimed from the “wet” waste. The TCPS should be able to recover nearly all the water from the trash for future use.

TCPS is a stand-alone system and only requires access to power, data, and air-cooling interfaces. It is being designed as simple to use.

Sierra Space said the device includes an innovative Catalytic Oxidizer (CatOx) “that processes volatile organic compounds (VOCs) and other gaseous byproducts to maintain a safe and sterile environment in space habitats.” Heat and pressure compacts astronaut trash into solid square tiles that compress to less than one-eighth of the original trash volume. The tiles are easy to store, safe to handle, and have the added — and potentially very important — benefit of providing additional radiation protection.

Sierra Space was originally awarded a contract in 2023, and in January 2024 they completed the initial design and review phase, which was presented to NASA for review. Sierra Space is now finalizing the fabrication, integration, and checkout of the TCPS Ground Unit, which will be used for ground testing in ongoing system evaluations. Based on the success of their design, Sierra Space was now awarded a new contract to build a Flight Unit that will be launched and tested in orbit aboard the space station.

NASA said that once tested on the ISS, the TCPS can be used for exploration missions wherever common spacecraft trash is generated and needs to be managed.

The most amazing thing about light is that it takes time to travel through space. Because of that one simple fact, when we look up at the Universe we see not a snapshot but a history. The photons we capture with our telescopes tell us about their journey. This is particularly true when gravity comes into play, since gravity bends and distorts the path of light. In a recent study, a team shows us how we might use this fact to better study black holes.

Near a black hole, our intuition about the behavior of light breaks down. For example, if we imagine a flash of light in empty space, we understand that the light from that flash expands outward in all directions, like the ripples on a pond. If we observe that flash from far away, we know the light has traveled in a straight line to reach us. This is not true near a black hole.

The gravity of a black hole is so intense that light never travels in a straight line. If there is a flash near a black hole, some of the light will travel directly to us, but some of the light will travel away from us, only to be gravitationally swept around the backside of the black hole to head in our direction. Some light will make a full loop around the black hole before reaching is. Or two loops, or three. With each path, the light travels a different distance to reach us, and therefore reaches us at a different time. Rather than observing a single flash, we wound see echoes of the flash for each journey.

In principle, since each echo is from a different path, the timing of these echoes would allow us to map the region around a black hole more clearly. The echoes would tell us not just the black hole’s mass and rotation; they would also allow us to test the limits of general relativity. The only problem is that with current observations, the echoes wash together in the data. We can’t distinguish different echoes.

This is where this new study comes in. The team propose observing a black hole with two telescopes, one on Earth and one in space. Each telescope would have a slightly different view of the black hole. Through long baseline interferometry the two sets of data could be correlated to distinguish the echoes. In their work the team ran tens of thousands of simulations of light echoes from a supermassive black hole similar to the one in the M87 galaxy. They demonstrated that interferometry could be used to find correlated light echoes.

It would be a challenge to build such an interferometer, but it would be well within our engineering capabilities. Perhaps in the future, we will be able to observe echoes of light to explore black holes and some of the deepest mysteries of gravity.

Placing a mass driver on the Moon has long been a dream of space exploration enthusiasts. It would open up so many possibilities for the exploration of our solar system and the possibility of actually living in space. Gerard O’Neill, in his work on the gigantic cylinders that now bear his name, mentioned using a lunar mass driver as the source of the material to build them. So far, we have yet to see such an engineering wonder in the real world, but as more research is done on the topic, more and more feasible paths seem to be opening up to its potential implementation. 

One recent contribution to that effort is a study by Pekka Janhunen of the Finnish Meteorological Institute and Aurora Propulsion Technologies, a maker of space-based propulsion systems. He details how we can use quirks of lunar gravity to use a mass driver to send passive loads to lunar orbit, where they can then be picked up with active, high-efficiency systems and sent elsewhere in the solar system for processing.

Anomalies in the Moon’s gravitational field have been known for some time. Typically, mission planners view them as a nuisance to be avoided, as they can cause satellite orbits to degrade more quickly than expected by nice, simple models. However, according to Dr. Janhunen, they could also be a help rather than a hindrance.

Mass drivers have been popular in science fiction for some time.

Typical models of using lunar mass drivers focus on active or passive payloads sent into lunar orbit. Active payloads require some onboard propulsion system to get them to where they are going. Therefore, these payloads require more active technology and some form of propellant, which diminishes the total amount available for use elsewhere in the solar system.

On the other hand, passive payloads will typically end up in one of two scenarios. Either they make one lunar orbit in about one day and then deorbit back to the lunar surface, or they end up in a highly randomized orbit and essentially end up as lunar space junk. Neither of those solutions would be sustainable for significant mass movement off the lunar surface.

Dr. Janhunen may have found a solution, though. He studied the known lunar gravitational anomalies found by GRAIL. This satellite mapped the Moon’s gravity in great detail and found several places on the lunar surface where a mass driver could potentially launch a passive payload into an orbit that would last up to nine days. These places are along the sides of mountains, and three of them are on the side of the lunar surface facing Earth. Importantly, all of them have their gravitational quirks.

The Artemis missions might be our best chance in the coming decades to build a mass driver on the Moon – Fraser discusses their details here.

More time in orbit would mean more time for an active tug to grab hold of the passive lunar payload and take it to a processing station, such as a space station at the L5 point between Earth and the Moon. This active tug could be reusable, have a highly efficient electrical propulsion system developed and built on Earth, and only need to be launched once.

All that would be required for the system to work would be a mass driver that could accelerate a payload up to a lunar orbital velocity of about 1.7 km/s. That is well within our capabilities to build with existing technologies, but it would require a massive engineering effort far beyond anything we have built-in space so far. However, every study that shows a potential increased benefit or lowered cost to eventually exploiting the resources of our nearest neighbor to expand our reach into the solar system takes us one step closer to making that a reality.

Sols 4357–4358: Turning West NASA’s Mars rover Curiosity acquired this image of its middle and right-rear wheels, using its Left Navigation Camera (Navcam). The difference in elevation between these two wheels at this location caused the drive planned on Monday, Nov. 4, 2024, to end early. Curiosity captured the image on Nov. 5, 2024, on sol 4355 — Martian day 4,355 of the Mars Science Laboratory mission — at 23:35:56 UTC. NASA/JPL-Caltech

Sols 4357–4358: Turning West

If you’ve ever driven down a road that’s in need of repaving, you’ll know that it can be an uncomfortable experience. The same is true on Mars: even at our carefully slow driving speed, the rough, rocky terrain that we’ve found ourselves in since entering Gediz Vallis many months ago continues to present challenges for our intrepid rover. 

Planning today began with the news that Curiosity only made it about halfway to its intended destination from Monday. The drive terminated early after the rover exceeded one of its “suspension limits.” This refers to our “rocker-bogie” suspension system, which allows the rover to drive over obstacles while minimizing the motion experienced by the rover body. In this case, our right middle wheel is down in a trough while the right rear wheel is perched on a rock, causing the angle of the “bogie” connecting the two wheels to exceed the maximum allowed value (Those maximums are set with a healthy amount of safety margin, so we’re not in any danger!). You can see the state of the bogie in the image above. On top of that, ending the drive early also meant that we didn’t have the images that we usually use to determine if the rover is stable enough to unstow the arm, so some creative work was necessary to determine whether or not we could. Unsurprisingly, the verdict was that we shouldn’t do so while in this awkward-looking position.

As always, the team was quick to pivot to a remote sensing plan. The focus today was on getting any last-minute remote observations of the Gediz Vallis channel. This was because we decided that, rather than continuing to drive north, we would be starting our western turn toward the exit out of Gediz Vallis.

The first sol of today’s plan contains a hefty two hours of science activities. These include LIBS observations of a bedrock target “North Dome” and a pair of ChemCam passive rasters of “Jewelry Lake” and “Merced River,” two smaller rocks near the rover, the latter of which appears to have been broken open as the rover drove over it. Mastcam will then take a documentation image of North Dome, as well as a mosaic of some more bedrock at “Earthquake Dome.” This first sol also includes a set of environmental science observations, including a lengthy 30-minute dust devil movie, just over 10 minutes of Navcam cloud movies, and some Navcam monitoring of dust and sand on the rover deck. We also sneak in a Navcam line-of-sight mosaic of the north crater rim, to measure the amount of dust in the air after our drive.

The second sol is a fairly typical post-drive sol, beginning with a standard ChemCam AEGIS activity to let the rover autonomously select a LIBS target. The rest of the science time this sol is dedicated to environmental monitoring, including a Mastcam tau observation to monitor dust, some more Navcam deck monitoring, another Navcam cloud movie, and a 360-degree Navcam dust devil survey. No arm activities means the second sol also includes a Navcam shunt prevention activity (SPENDI) to burn off some extra power while also looking for clouds and dust devils. As always, REMS, RAD, and DAN will continue their standard activities throughout this plan.

When I joined the mission back in 2020, I would occasionally look at Gediz Vallis on our HiRISE maps and imagine what the view would be like between those tall, steep channel walls. So it seems almost unbelievable that we will soon be leaving Gediz Vallis behind us as we continue our trek up Mount Sharp. It will probably still be a few more weeks before we can say that we’ve officially exited Gediz Vallis, but I don’t think anyone will be saying they were disappointed with what we accomplished during this long-anticipated phase of the mission.

Onwards and upwards!

TIME Recognizes the Advanced Composite Solar Sail System

In October, the Advanced Composite Solar Sail System a project managed at NASA Ames, was recognized by TIME Magazine as a “Top Invention of 2024”! TIME Magazine also recognized two other NASA missions this year: Europa Clipper, and the Deep Space Optical Communications experiment.   

The Advanced Composite Solar Sail System is a demonstration of technologies that enable spacecraft to “sail on sunlight,” using solar radiation for propulsion. Results from this mission could provide an alternative to chemical and electric propulsion systems and guide the design of future larger-scale spacecraft for space weather early warning satellites, near-Earth asteroid reconnaissance missions, or communications relays for crewed exploration missions at the Moon and Mars.  

The Advanced Composite Solar Sail System a project managed at NASA Ames, was recognized by TIME Magazine as a “Top Invention of 2024.”NASA

This twelve-unit (12U) CubeSat features a reflective sail held taut by composite booms made from flexible polymer and carbon fiber materials that are stiffer and lighter than previous designs. The square-shaped solar sail measures approximately 80 square meters, but the new boom technology could support future missions for solar sails up to 500 square meters.   

The mission launched on April 23 via a Rocket Lab Electron rocket and met its primary objective in August by deploying the boom and sail system in space. Next, the team will attempt to demonstrate maneuverability in orbit using the sail.   

Congratulations to the Advanced Composite Solar Sail System team and the Small Spacecraft Technology program office, based at Ames, for this well-earned recognition. Their contributions continue to push the boundaries of what we can achieve at NASA, and this acknowledgment highlights the capabilities and vision of our center.

NASA and Partners Scaling to New Heights in Air Traffic Management

by Hillary Smith

NASA, in partnership with AeroVironment and Aerostar, recently demonstrated a first-of-its-kind air traffic management concept that could pave the way for aircraft to safely operate at higher altitudes.

This work seeks to open the door for increased internet coverage, improved disaster response, expanded scientific missions, and even supersonic flight. The concept is referred to as an Upper-Class E traffic management, or ETM.  There is currently no traffic management system or set of regulations in place for aircraft operating 60,000 feet and above. There hasn’t been a need for a robust traffic management system in this airspace until recently. That’s because commercial aircraft couldn’t function at such high altitudes due to engine constraints.

However, recent advancements in aircraft design, power, and propulsion systems are making it possible for high- altitude, long-endurance vehicles — such as balloons, airships, and solar aircraft — to coast miles above our heads, providing radio relay for disaster response, collecting atmospheric data, and more.  

But before these aircraft can regularly take to the skies, operators must find a way to manage their operations without overburdening air traffic infrastructure and personnel.  

“We are working to safely expand high-altitude missions far beyond what is currently possible,” said Kenneth Freeman, a subproject manager for this effort at NASA’s Ames Research Center in California’s Silicon Valley. “With routine, remotely piloted high-altitude operations, we have the opportunity to improve our understanding of the planet through more detailed tracking of climate change, provide internet coverage in underserved areas, advance supersonic flight research, and more.” 

Current high-altitude traffic management is processed manually and on a case-by-case basis. Operators must contact air traffic control to gain access to a portion of the Class E airspace. During these operations, no other aircraft can enter this high-altitude airspace. This method will not accommodate the growing demand for high-altitude missions, according to NASA researchers.  

To address this challenge, NASA and its partners have developed an ETM traffic management system that allows aircraft to autonomously share location and flight plans, enabling aircraft to stay safely separated. 

During the recent traffic management simulation in the Airspace Operations Laboratory at Ames, data from multiple air vehicles was displayed across dozens of traffic control monitors and shared with partner computers off site.

This included aircraft location, health, flight plans and more. Researchers studied interactions between a slow fixed-wing vehicle from AeroVironment and a high-altitude balloon from Aerostar operating at stratospheric heights.

Each aircraft, connected to the ETM traffic management system for high altitude, shared location and flight plans with surrounding aircraft.  

This digital information sharing allowed Aerostar and AeroVironment high-altitude vehicle operators to coordinate and deconflict with each other in the same simulated airspace, without having to gain approval from air traffic control.

Because of this, aircraft operators were able to achieve their objectives, including wireless communication relay. 

This simulation represents the first time a traffic management system was able to safely manage a diverse set of high-altitude aircraft operations in the same simulated airspace.

Next, NASA researchers will work with partners to further validate this system through a variety of real flight tests with high-altitude aircraft in a shared airspace.   

The Upper-Class E traffic management concept was developed in coordination with the Federal Aviation Administration and high-altitude platform industry partners, under NASA’s National Airspace System Exploratory Concepts and Technologies subproject led out of Ames.  

Starship Super Heavy Breezes Through Wind Tunnel Testing at NASA Ames

by Lee Mohon

NASA and its industry partners continue to make progress toward Artemis III and beyond, the first crewed lunar landing missions under the agency’s Artemis campaign. SpaceX, the commercial Human Landing System (HLS) provider for Artemis III and Artemis IV, recently tested a 1.2% scale model of the Super Heavy rocket, or booster, in the transonic Unitary Plan Wind Tunnel at NASA Ames. The Super Heavy rocket will launch the Starship human landing system to the Moon as part of Artemis.

A 1.2% scale model of the Super Heavy rocket that will launch the Starship human landing system to the Moon for future crewed Artemis missions was recently tested at NASA Ames’ transonic wind tunnel, providing valuable information on vehicle stability when re-entering Earth’s atmosphere.NASA

During the tests, the wind tunnel forced an air stream at the Super Heavy scale model at high speeds, mimicking the air resistance and flow the booster experiences during flight. The wind tunnel subjected the Super Heavy model, affixed with pressure-measuring sensors, to wind speeds ranging from Mach .7, or about 537 miles per hour, to Mach 1.4, or about 1,074 miles per hour. Mach 1 is the speed that sound waves travel, or 761 miles per hour, at sea level.

Engineers then measured how Super Heavy model responded to the simulated flight conditions, observing its stability, aerodynamic performance, and more. Engineers used the data to update flight software for flight 3 of Super Heavy and Starship and to refine the exterior design of future versions of the booster. The testing lasted about two weeks and took place earlier in 2024.

After Super Heavy completes its ascent and separation from Starship HLS on its journey to the Moon, SpaceX plans to have the booster return to the launch site for catch and reuse. The Starship HLS will continue on a trajectory to the Moon.

To get to the Moon for the Artemis missions, astronauts will launch in NASA’s Orion spacecraft aboard the SLS (Space Launch System) rocket from the agency’s Kennedy Space Center in Florida. Once in lunar orbit, Orion will dock with the Starship HLS or with Gateway. Once the spacecraft are docked, the astronauts will move from Orion or Gateway to the Starship HLS, which will bring them to the surface of the Moon. After surface activities are complete, Starship will return the astronauts to Orion or Gateway waiting in lunar orbit. The astronauts will transfer to Orion for the return trip to Earth. 

With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

NASA astronauts, scientists, and researchers, and leadership from the University of California, San Francisco (UCSF) met with cancer patients and gathered in a discussion about potential research opportunities and collaborations as part of President Biden and First Lady Jill Biden’s Cancer Moonshot initiative on Oct. 4.

Roundtable discussions centered conversation around the five hazards of human spaceflight: space radiation, isolation and confinement, distance from Earth, gravity, and closed or hostile environments. Many of these hazards have direct correlations to a cancer patient’s lived experience, like the isolation of a hospital room and long-term effects of radiation.

NASA Begins New Deployable Solar Array Tech Demo on Pathfinder Spacecraft

by Gianine Figliozzi

NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft’s systems including its on-board electronics as well as the payload’s support systems such as the small onboard camera. Shown below is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This camera will continue photographing the technology demonstration during the mission. 

Payload operations are now underway for the primary objective of the PTD-4 mission – the demonstration of a new power and communications technology for future spacecraft. The payload, a deployable solar array with an integrated antenna called the Lightweight Integrated Solar Array and anTenna, or LISA-T, has initiated deployment of its central boom structure. The boom supports four solar power and communication arrays, also called petals. Releasing the central boom pushes the still-stowed petals nearly three feet (one meter) away from the spacecraft bus. The mission team currently is working through an initial challenge to get LISA-T’s central boom to fully extend before unfolding the petals and beginning its power generation and communication operations.

Small spacecraft on deep space missions require more electrical power than what is currently offered by existing technology. The four-petal solar array of LISA-T is a thin-film solar array that offers lower mass, lower stowed volume, and three times more power per mass and volume allocation than current solar arrays. The in-orbit technology demonstration includes deployment, operation, and environmental survivability of the thin-film solar array.  

“The LISA-T experiment is an opportunity for NASA and the small spacecraft community to advance the packaging, deployment, and operation of thin-film, fully flexible solar and antenna arrays in space. The thin-film arrays will vastly improve power generation and communication capabilities throughout many different mission applications,” said Dr. John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.”

The Pathfinder Technology Demonstration series of missions leverages a commercial platform which serves to test innovative technologies to  increase the capability of small spacecraft. Deploying LISA-T’s thin solar array in the harsh environment of space presents inherent challenges such as deploying large highly flexible non-metallic structures with high area to mass ratios. Performing experiments such as LISA-T on a smaller, lower-cost spacecraft allows NASA the opportunity to take manageable risk with high probability of great return. The LISA-T experiment aims to enable future deep space missions with the ability to acquire and communicate data through improved power generation and communication capabilities on the same integrated array.

The PTD-4 small spacecraft is hosting the in-orbit technology demonstration called LISA-T. The PTD-4 spacecraft deployed into low Earth orbit from SpaceX’s Transporter-11 rocket which launched from Space Launch Complex 4E at Vandenberg Space Force Base in California on Aug. 16. NASA’s Marshall Space Flight Center in Huntsville, Alabama designed and built the LISA-T technology as well as LISA-T’s supporting avionics system. NASA’s Small Spacecraft Technology program, based at NASA’s Ames Research Center in California’s Silicon Valley and led by the agency’s Space Technology Mission Directorate, funds and manages the PTD-4 mission as well as the overall Pathfinder Technology Demonstration mission series. Terran Orbital Corporation of Irvine, California, developed and built the PTD-4 spacecraft bus, named Triumph.

Faces of NASA – Ames’ Dr. Donald Mendoza, Chief Engineer

“From my earliest childhood, flight had always captivated me. I lived out in the boonies and the farmlands, so I didn’t have neighbors to go and play with. If I wasn’t working, I was left to my own devices, and often, I would just be captivated by the wildlife and in particular, the birds of prey that I would see.

Dr. Donald Menodoza, Chief Engineer, NASA Engineering and Safety Center at Ames.NASA photo by Dominic Hart

“To me, they represented a freedom of some kind or another. These birds and the view they have — they can take in so much. So, from that point on, I knew I wanted to be involved in flight and aviation.

“I [enjoyed] all things flight, all things spaceflight. I couldn’t get enough of it. I became an avid reader, whereas before, I wasn’t much of a reader. I couldn’t get enough material to read about my heroes from flight and space. They became my role models and the path that they took involved, at some point or another, a pretty rigorous education and dedication to doing well academically, physically, or athletically. So, I threw myself into that entire sort of mindset.

“When I was working for the Air Force, I was able to fly and work on aircraft that I would dream about, looking at in the magazines Aviation Week and Space Technology. Here they are, right in front of me.

“… So, my career has been as close as possible to that of a flight test engineer. And then, right on the heels of being captivated by atmospheric flight, working in human spaceflight has put me over the Moon.”

We Are All Made of Cells: Space and the Immune System

by Rachel Hoover

Malcolm O’Malley and his mom sat nervously in the doctor’s office awaiting the results of his bloodwork. This was no ordinary check-up. In fact, this appointment was more urgent and important than the SATs the seventeen-year-old, college hopeful had spent months preparing for and was now missing in order to understand his symptoms. 

But when the doctor shared the results – he had off-the-charts levels of antibodies making him deathly allergic to shellfish – O’Malley realized he had more questions than answers. Like: Why is my immune system doing this? How is it working? Why is it reacting so severely and so suddenly (he’d enjoyed shrimp less than a year ago)? And why does the only treatment – an injection of epinephrine – have nothing to do with the immune system, when allergies appear to be an immune system problem? Years later, O’Malley would look to answer some of these questions while interning in the Space Biosciences Research Branch at NASA’s Ames Research Center in California’s Silicon Valley.

“Anaphylaxis is super deadly and the only treatment for it is epinephrine; and I remember thinking, ‘how is this the best we have?’ because epinephrine does not actually treat the immune system at all – it’s just adrenaline,” said O’Malley, who recently returned to his studies as a Ph.D. student of Biomedical Engineering at the University of Virginia (UVA) in Charlottesville. “And there’s a thousand side effects, like heart attacks and stroke – I remember thinking ‘these are worse than the allergy!’”

O’Malley’s curiosity and desire to better understand the mechanisms and connections between what triggers different immune system reactions combined with his interest in integrating datasets into biological insights inspired him to shift his major from computer science to biomedical engineering as an undergraduate student. With his recent allergy diagnosis and a lifelong connection to his aunt who worked at the UVA Heart and Vascular Center, O’Malley began to build a bridge between the immune system and heart health. By the time he was a senior in college, he had joined the Cardiac Systems Biology Lab, and had chosen to focus his capstone project on better understanding the role of neutrophils, a specific type of immune cell making up 50 to 70% of the immune system, that are involved in cardiac inflammation in high blood pressure and after heart attacks.

“The immune system is involved in everything,” O’Malley says. “Anytime there’s an injury – a paper cut, a heart attack, you’re sick – the immune system is going to be the first to respond; and neutrophils are the first responders.”

O’Malley’s work to determine what regulates the immune system’s interrelated responses – like how one cell could affect other cells or immune processes downstream – provided a unique opportunity for him to support multiple interdisciplinary NASA biological and physical sciences research projects during his 10-week internship at NASA Ames over the summer of 2024. O’Malley applied machine learning techniques to the large datasets the researchers were using from experiments and specimens collected over many years to help identify possible causes of inflammation seen in the heart, brain, and blood, as well as changes seen in bones, metabolism, the immune system, and more when humans or other model organisms are exposed to decreased gravity, social isolation, and increased radiation. These areas are of keen interest to NASA due to the risks to human health inherent in space exploration and the agency’s plans to send humans on long-duration missions to the Moon, Mars, and beyond.

“It’s exciting that we just never know what’s going to happen, how the immune system is going to react until it’s already been activated or challenged in some way,” said O’Malley. “I’m particularly interested in the adaptive immune system because it’s always evolving to meet new challenges; whether it’s a pandemic-level virus, bacteria or something on a mission to Mars, our bodies are going to have some kind of adaptive immune response.”

During his NASA internship, O’Malley applied a statistical analysis techniques to plot and make more sense of the massive amounts of life sciences data. From there, researchers could find out which proteins, out of hundreds, or attributes – like differences in sex – are related to which behaviors or outcomes. For example, through O’Malley’s analysis, researchers were able to better pinpoint the proteins involved in inflammation of the brain that may play a protective role in spatial memory and motor control during and after exposure to radiation – and how we might be able to prevent or mitigate those impacts during future space missions and even here on Earth.

“I had this moment where I realized that since my internship supports NASA’s Human Research Program that means the work I’m doing directly applies to Artemis, which is sending the first woman and person of color to the Moon,” reflected O’Malley. “As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen.”

When O’Malley wasn’t exploring the mysteries of the immune system for the benefit of all at NASA Ames, he taught himself how to ride a bike and started to surf in the nearby waters of the Pacific Ocean. O’Malley considers Palmyra, Virginia, his hometown and he enjoys playing sports – especially volleyball, water polo, and tennis – reading science fiction and giving guest lectures to local high school students hoping to spark their curiosity. 

O’Malley’s vision for the future of biomedical engineering reflects his passion for innovation. “I believe that by harnessing the unique immune properties of other species, we can achieve groundbreaking advancements in limb regeneration, revolutionize cancer therapy, and develop potent antimicrobials that are considered science fiction today,” he said.

NASA is not yet providing details about what caused a SpaceX Crew-8 astronaut to be hospitalized late last month, citing medical privacy concerns.

Boom Supersonic's XB-1 aircraft set a new speed record during its latest test flight on Nov. 5, marking a major milestone toward flying at supersonic speeds.

Massive stars about eight times more massive than the Sun explode as supernovae at the end of their lives. The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies for months. However, astronomers appear to have spotted a massive star that skipped the explosion and turned directly into a black hole.

Stars are balancing acts between the outward force of fusion and the inward force of their own gravity. When a massive star enters its last evolutionary stages, it begins to run out of hydrogen, and its fusion weakens. The outward force from its fusion can no longer counteract the star’s powerful gravity, and the star collapses in on itself. The result is a supernova explosion, a calamitous event that destroys the star and leaves behind a black hole or a neutron star.

However, it appears that sometimes these stars fail to explode as supernovae and instead turn directly into black holes.

New research shows how one massive, hydrogen-depleted supergiant star in the Andromeda galaxy (M31) failed to detonate as a supernova. The research is “The disappearance of a massive star marking the birth of a black hole in M31.” The lead author is Kishalay De, a postdoctoral scholar at the Kavli Institute for Astrophysics and Space Research at MIT.

These types of supernovae are called core-collapse supernovae, also known as Type II. They’re relatively rare, with one occurring about every one hundred years in the Milky Way. Scientists are interested in supernovae because they are responsible for creating many of the heavy elements, and their shock waves can trigger star formation. They also create cosmic rays that can reach Earth.

This new research shows that we may not understand supernovae as well as we thought.

The star in question is named M31-2014-DS1. Astronomers noticed it brightening in mid-infrared (MIR) in 2014. For one thousand days, its luminosity was constant. Then, for another thousand days between 2016 and 2019, it faded dramatically. It’s a variable star, but that can’t explain these fluctuations. In 2023, it was undetected in deep optical and near-IR (NIR) imaging observations.

The researchers say that the star was born with an initial mass of about 20 stellar masses and reached its terminal nuclear-burning phase with about 6.7 stellar masses. Their observations suggest that the star is surrounded by a recently ejected dust shell, in accordance with a supernova explosion, but there’s no evidence of an optical outburst.

“The dramatic and sustained fading of M31-2014-DS1 is exceptional in the landscape of variability in massive, evolved stars,” the authors write. “The sudden decline of luminosity in M31-2014-DS1 points to the cessation of nuclear burning together with a subsequent shock that fails to overcome the infalling material.” A supernova explosion is so powerful that it completely overcomes infalling material.

“Lacking any evidence for a luminous outburst at such proximity, the observations of M31-2014-DS1 bespeak signatures of a ‘failed’ SN that leads to the collapse of the stellar core,” the authors explain.

What could make a star fail to explode as a supernova, even if it’s the right mass to explode?

Supernovae are complex events. The density inside a collapsing core is so extreme that electrons are forced to combine with protons, creating both neutrons and neutrinos. This process is called neutronization, and it creates a powerful burst of neutrinos that carries about 10% of the star’s rest mass energy. The outburst is called a neutrino shock.

Neutrinos get their name from the fact that they’re electrically neutral and seldom interact with regular matter. Every second, about 400 billion neutrinos from our Sun pass right through every person on Earth. But in a dense stellar core, the neutrino density is so extreme that some of them deposit their energy into the surrounding stellar material. This heats the material, which generates a shock wave.

The neutrino shock always stalls, but sometimes it revives. When it revives, it drives an explosion and expels the outer layer of the supernova. If it’s not revived, the shock wave fails, and the star collapses and forms a black hole.

This image illustrates how the neutrino shock wave can stall, leading to a black hole without a supernova explosion. A shows the initial shock wave with cyan lines representing neutrinos being emitted and the red circle representing the shock wave propagating outward. B shows the neutrino shock stalling, with white arrows representing infalling matter. The outer layers fall inward, and the neutrino heating isn’t powerful enough to revive the shock. C shows the failed shock dissipating as a dotted red line and the stronger white arrows represent the collapse accelerating. The outer layers are falling in rapidly, and the core is becoming more compact. D shows the black hole forming, with the blue circle representing the event horizon and the remaining material forming an accretion disk. (Credit: Original illustration created for this article.)

In M31-2014-DS1, the neutrino shock was not revived. The researchers were able to constrain the amount of material ejected by the star, and it was far below what a supernovae would eject. “These constraints imply that the majority of stellar material (?5 solar masses) collapsed into the core, exceeding the maximum mass of a neutron star (NS) and forming a BH,” they conclude. About 98% of the star’s mass collapsed and created a black hole with about 6.5 solar masses.

M31-2014-DS1 isn’t the only failed supernova, or candidate failed supernova, that astronomers have found. They’re difficult to spot because they’re characterized by what doesn’t happen rather than what does. A supernova is hard to miss because it’s so bright and appears in the sky suddenly. Ancient astronomers recorded several of them.

In 2009, astronomers discovered the only other confirmed failed supernova. It was a supergiant red star in NGC 6946, the “Fireworks Galaxy.” It’s named N6946-BH1 and has about 25 solar masses. After disappearing from view, it left only a faint infrared glow. In 2009, its luminosity increased to a million solar luminosities, but by 2015, it had disappeared in optical light.

A survey with the Large Binocular Telescope monitored 27 nearby galaxies, looking for disappearing massive stars. The results suggest that between 20% and 30% of massive stars can end their lives as failed supernovae. However, M31-2014-DS1 and N6946-BH1 are the only confirmed observations.
