Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people

NASA to Launch Three Rockets from Alaska in Single Aurora Experiment

NASA to Launch Three Rockets from Alaska in Single Aurora Experiment

Three NASA-funded rockets are set to launch from Poker Flat Research Range in Fairbanks, Alaska, in an experiment that seeks to reveal how auroral substorms affect the behavior and composition of Earth’s far upper atmosphere. 

The experiment’s outcome could upend a long-held theory about the aurora’s interaction with the thermosphere. It may also improve space weather forecasting, critical as the world becomes increasingly reliant on satellite-based devices such as GPS units in everyday life.

The University of Alaska Fairbanks (UAF) Geophysical Institute owns Poker Flat, located 20 miles north of Fairbanks, and operates it under a contract with NASA’s Wallops Flight Facility in Virginia, which is part of NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The experiment, titled Auroral Waves Excited by Substorm Onset Magnetic Events, or AWESOME, features one four-stage rocket and two two-stage rockets all launching in an approximately three-hour period.

Colorful vapor tracers from the largest of the three rockets should be visible across much of northern Alaska. The launch window is March 24 through April 6.

The mission, led by Mark Conde, a space physics professor at UAF, involves about a dozen UAF graduate student researchers at several ground monitoring sites in Alaska at Utqiagvik, Kaktovik, Toolik Lake, Eagle, and Venetie, as well as Poker Flat.  NASA delivers, assembles, tests, and launches the rockets.

“Our experiment asks the question, when the aurora goes berserk and dumps a bunch of heat in the atmosphere, how much of that heat is spent transporting the air upward in a continuous convective plume and how much of that heat results in not only vertical but also horizontal oscillations in the atmosphere?” Conde said.

Confirming which process is dominant will reveal the breadth of the mixing and the related changes in the thin air’s characteristics.

“Change in composition of the atmosphere has consequences,” Conde said. “And we need to know the extent of those consequences.”

Most of the thermosphere, which reaches from about 50 to 350 miles above the surface, is what scientists call “convectively stable.” That means minimal vertical motion of air, because the warmer air is already at the top, due to absorption of solar radiation.

When auroral substorms inject energy and momentum into the middle and lower thermosphere (roughly 60 to 125 miles up), it upsets that stability. That leads to one prevailing theory — that the substorms’ heat is what causes the vertical-motion churn of the thermosphere.

Conde believes instead that acoustic-buoyancy waves are the dominant mixing force and that vertical convection has a much lesser role. Because acoustic-buoyancy waves travel vertically and horizontally from where the aurora hits, the aurora-caused atmospheric changes could be occurring over a much broader area than currently believed.

Better prediction of impacts from those changes is the AWESOME mission’s practical goal.

“I believe our experiment will lead to a simpler and more accurate method of space weather prediction,” Conde said.

Two two-stage, 42-foot Terrier-Improved Malemute rockets are planned to respectively launch about 15 minutes and an hour after an auroral substorm begins. A four-stage, 70-foot Black Brant XII rocket is planned to launch about five minutes after the second rocket. 

The first two rockets will release tracers at altitudes of 50 and 110 miles to detect wind movement and wave oscillations. The third rocket will release tracers at five altitudes from 68 to 155 miles.
Pink, blue, and white vapor traces should be visible from the third rocket for 10 to 20 minutes. Launches must occur in the dawn hours, with sunlight hitting the upper altitudes to activate the vapor tracers from the first rocket but darkness at the surface so ground cameras can photograph the tracers’ response to air movement.

NASA Reveals Semifinalists of Power to Explore Challenge A word cloud showing “superpowers” of the 45 semifinalists.NASA/David Lam

NASA selected 45 student essays as semifinalists of its 2024-2025 Power to Explore Challenge, a national competition for K-12 students featuring the enabling power of radioisotopes. Contestants were challenged to explore how NASA has powered some of its most famous science missions and to dream up how their personal “superpower” would energize their success on their own radioisotope-powered science mission to explore one of the nearly 300 moons of our solar system.

The competition asked students to learn about radioisotope power systems (RPS), a type of “nuclear battery” that NASA uses to explore the harshest, darkest, and dustiest parts of our solar system. RPS have enabled many spacecraft to explore a variety of these moons, some with active volcanoes, methane lakes, and intricate weather patterns similar to Earth. Many of these moons remain a mystery to us.

This year’s submissions to NASA’s Power to Explore Challenge were immensely enthralling, and we’re thrilled that the number of entries reached a record high.

Carl Sandifer II

Program Manager, NASA Radioisotope Power Systems Program

In 275 words or less, students wrote about a mission of their own that would use these space power systems to explore any moon in our solar system and described their own power to achieve their mission goals.

The Power to Explore Challenge offered students the opportunity to learn more about these reliable power systems, celebrate their own strengths, and interact with NASA’s diverse workforce. This year’s contest set a record, receiving 2,051 submitted entries from all 50 states, Guam, U.S. Virgin Islands, American Samoa, Northern Mariana Islands, Puerto Rico, and the Department of Defense Education Activity (DoDEA) Overseas.

“This year’s submissions to NASA’s Power to Explore Challenge were immensely enthralling, and we’re thrilled that the number of entries reached a record high,” said Carl Sandifer II, program manager of the Radioisotope Power Systems Program at NASA’s Glenn Research Center in Cleveland. “It was particularly interesting to see which moons the students selected for their individual essays, and the mysteries they hope to unravel. Their RPS-powered mission concepts always prove to be innovative, and it’s a joy to learn about their ‘superpowers’ that exemplify their path forward as the next generation of explorers.” 

Entries were split into three categories: grades K-4, 5-8, and 9-12. Every student who submitted an entry received a digital certificate, and over 4,859 participants who signed up received an invitation to the Power Up with NASA virtual event. Students learned about what powers the NASA workforce utilizes to dream big and work together to explore. Speakers included Carl Sandifer II, Dr. Wanda Peters, NASA’s deputy associate administrator for programs in the Science Mission Directorate and Dr. Zibi Turtle, principal investigator for NASA’s Dragonfly mission from the John Hopkins Applied Physics Laboratory.

A dolphin swims through the water in the Launch Complex 39 Area turn basin at NASA’s Kennedy Space Center in Florida on Nov. 6, 2007. The turn basin was carved out of the Banana River when NASA Kennedy was built. Dolphins are a frequent sight in the rivers around Kennedy, which shares a boundary with the Merritt Island Wildlife Nature Refuge.

The refuge was established in 1963 for the protection of migratory birds. Consisting of 140,000 acres, the refuge provides a wide variety of habitats: coastal dunes, saltwater marshes, managed impoundments, scrub, pine flatwoods, and hardwood hammocks. These habitats provide a home for more than 1,500 species of plants and animals and 15 federally listed species.

NASA’s Artemis II Orion Service Module Buttoned Up for Launch

NASA News - Fri, 03/21/2025 - 11:55am

Technicians with NASA and Lockheed Martin fitted three spacecraft adapter jettison fairing panels onto the service module of the agency’s Orion’s spacecraft. The operation completed on Wednesday, March 19, 2025, inside the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida.

The European-built service module is the powerhouse that will propel the spacecraft to the Moon. Its four solar array wings which were installed to its exterior in early March. The latest addition of fairing panels on Orion’s service module will protect the solar array wings, shielding them from the heat, wind, and acoustics of launch and ascent, and also help redistribute the load between Orion and the massive thrust of the SLS (Space Launch System) rocket during liftoff and ascent. Once the spacecraft is above the atmosphere, the three fairing panels will separate from the service module, allowing the wings to unfurl.

In addition to power, the service module will provide propulsion and life support including thermal control, air, and water for the Artemis II test flight, NASA’s first mission with crew under the Artemis campaign that will send NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon.  

Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

After delivering more than 8,200 pounds of supplies, scientific investigations, commercial products, hardware, and other cargo to the orbiting laboratory for NASA and its international partners, Northrop Grumman’s uncrewed Cygnus spacecraft is scheduled to depart the International Space Station on Friday, March 28.

Watch NASA’s live coverage of undocking and departure at 6:30 a.m. EDT on NASA+. Learn how to watch NASA content through a variety of platforms, including social media.

This mission was the company’s 21st commercial resupply mission to the space station for NASA.

Flight controllers on the ground will send commands for the space station’s Canadarm2 robotic arm to detach Cygnus from the Unity module’s Earth-facing port, then maneuver the spacecraft into position for release at 6:55 a.m. NASA astronaut Nichole Ayers will monitor Cygnus’ systems upon its departure from the space station.

Cygnus – filled with trash packed by the station crew – will be commanded to deorbit on Sunday, March 30, setting up a re-entry where the spacecraft will safely burn up in Earth’s atmosphere.

The Northrop Grumman spacecraft arrived at the space station Aug. 6, 2024, following launch on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

Get breaking news, images, and features from the space station on the station blog, Instagram, Facebook, and X.

3D Printing: Saving Weight and Space at Launch

NASA - Breaking News - Fri, 03/21/2025 - 10:00am

Additive manufacturing, also known as 3D printing, is regularly used on the ground to quickly produce a variety of devices. Adapting this process for space could let crew members create tools and parts for maintenance and repair of equipment on the spot, rather than trying to bring along every item that might be needed.

The ability to manufacture things in space is especially important in planning for missions to the Moon and Mars because additional supplies cannot quickly be sent from Earth and cargo capacity is limited.

Research on the International Space Station is helping to develop the capability to address multiple needs using 3D printing.

Metal 3D Printer, a current investigation from ESA (European Space Agency), tests 3D printing of small metal parts in microgravity. Results could improve understanding of the function, performance, and operations of 3D printing in space with metal, as well as the quality, strength, and characteristics of printed parts. This work also could benefit applications on Earth that use metal, such as the automotive, aeronautical, and maritime industries.

Printing with plastic NASA Astronaut Butch Wilmore holds a ratchet wrench created with the 3D Printing in Zero-G printer.NASA

3D Printing in Zero-G sent the first 3D printer, developed by NASA’s Marshall Space Flight Center and Redwire (formerly Made in Space), to the space station in 2014. The printer used a process that feeds a continuous thread of plastic through a heated extruder and onto a tray layer by layer to create an object. The investigation produced more than a dozen parts, including a ratchet wrench, showing that researchers could send a design from the ground to the system on the station more than 200 miles above.

Comparing the parts made in space with those made on the ground showed that microgravity had no significant effect on the process.

Redwire then developed the Additive Manufacturing Facility (AMF), sent to the station in 2015. Researchers evaluated its mechanical performance and found improvements in tension strength and flexibility compared to the earlier demonstration, helping to further the technology for this type of manufacturing on Earth and in space.

In 2015 and 2016, Portable On Board 3D Printer tested an automated printer developed by the Italian Space Agency to produce plastic objects in space. The investigation provided insight into how the material behaves in microgravity, which could support development of European additive manufacturing technology for use in space.

Printing with other materials NASA astronaut Anne McClain installs the Refabricator in Feb. 2019.NASA

Another approach is recycling plastic – for example, turning a used 3D-printed wrench into a spoon and creating items from the plastic bags and packing foam needed to send supplies to space. This technology could help reduce the amount of raw material at launch and cut down on the volume of waste that must be disposed of on long journeys. The Refabricator, a machine created by Tethers Unlimited Inc, tested this approach and successfully manufactured its first object. Some issues occurred in the bonding process, likely caused by microgravity, but assessment of the material could help determine whether there are limits to how many times plastic can be re-used. Ultimately, researchers plan to create a database of parts that can be manufactured using the space station’s capabilities.

Redwire Regolith Print (RRP) tested another kind of feedstock for 3D manufacturing in orbit, a simulated version of regolith, the dust present on the surface of the Moon and other planetary bodies. Results could lead to development of technology for using regolith to construct habitats and other structures rather than bringing raw materials from Earth.

The space station also has hosted studies of a form of 3D printing called biological printing or bioprinting. This process uses living cells, proteins, and nutrients as raw materials to potentially produce human tissues for treating injury and disease, which could benefit future crews and patients on Earth.

Other manufacturing techniques tested on the orbiting lab include producing optical fibers and growing crystals for synthesizing pharmaceuticals and fabricating semiconductors.

Hubble Captures a Neighbor’s Colorful Clouds This NASA/ESA Hubble Space Telescope image features part of the Small Magellanic Cloud. ESA/Hubble & NASA, C. Murray
Download this image

Say hello to one of the Milky Way’s neighbors! This NASA/ESA Hubble Space Telescope image features a scene from one of the closest galaxies to the Milky Way, the Small Magellanic Cloud (SMC). The SMC is a dwarf galaxy located about 200,000 light-years away. Most of the galaxy resides in the constellation Tucana, but a small section crosses over into the neighboring constellation Hydrus.

Thanks to its proximity, the SMC is one of only a few galaxies that are visible from Earth without the help of a telescope or binoculars. For viewers in the southern hemisphere and some latitudes in the northern hemisphere, the SMC resembles a piece of the Milky Way that has broken off, though in reality it’s much farther away than any part of our own galaxy.

With its 2.4-meter mirror and sensitive instruments, Hubble’s view of the SMC is far more detailed and vivid than what humans can see. Researchers used Hubble’s Wide Field Camera 3 to observe this scene through four different filters. Each filter permits different wavelengths of light, creating a multicolored view of dust clouds drifting across a field of stars. Hubble’s view, however, is much more zoomed-in than our eyes, allowing it to observe very distant objects. This image captures a small region of the SMC near the center of NGC 346, a star cluster that is home to dozens of massive young stars.

Sols 4484-4485: Remote Sensing on a Monday

4 min read

Sols 4484-4485: Remote Sensing on a Monday NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on March 17, 2025 — sol 4483, or Martian day 4,483 of the Mars Science Laboratory mission — at 09:38:17 UTC. NASA/JPL-Caltech

Written by Conor Hayes, Graduate Student at York University

Earth planning date: Monday, March 17, 2025

Last week I was in Houston, Texas, at the Lunar and Planetary Science Conference. The mid-March weather in Houston is often more like mid-summer weather here in Toronto, so it has been a bit of a shock coming home to temperatures that are hovering around freezing rather than being in the upper 20s (degrees Celsius, or the low to mid 80s for those of you still using Fahrenheit). Still, Toronto is positively balmy compared to Gale Crater, where temperatures usually range between minus 80°C and minus 20°C (or minus 110°F to minus 5°F) during this part of the year. These cold temperatures and their associated higher demands on the rover’s available power for heating are continuing to motivate many of the decisions that we make during planning.

We received the double good news this morning that the weekend’s drive completed successfully, including the mid-drive imaging of the other side of “Humber Park” that Michelle mentioned in Friday’s blog, and that our estimates of the weekend plan’s power consumption ended up being a little conservative. So we started planning exactly where we wanted to be, and with more power to play around with than we had expected. Yay!

The weekend’s drive left us parked in front of some rocks with excellent layering and interesting ripples that we really wanted to get a closer look at with MAHLI. (See the cover image for a look at these rocks as seen by Navcam.) Sadly, we also ended up parked in such a way that presented a slip hazard if the arm was unstowed. As much as we would have loved to get close-up images of these rocks, we love keeping Curiosity’s arm safe even more, so we had to settle for a remote sensing-only plan instead.

Both the geology and mineralogy (GEO) and the environmental science (ENV) teams took full advantage of the extra power gifted to us today to create a plan packed full of remote sensing observations. Because we’re driving on the first sol of this two-sol plan, any “targeted” observations, i.e. those where we know exactly where we want to point the rover’s cameras, must take place before the drive. The first sol is thus packed full of Mastcam and ChemCam observations, starting with a 14×3 Mastcam mosaic of the area in front of us that’s outside of today’s workspace. Individual targets then get some Mastcam love with mosaics of various ripple and layering features at “Verdugo Peak,” “Silver Moccasin Trail,” and “Jones Peak.” Mastcam and ChemCam also team up on a LIBS target, “Trancas Canyon,” and some more long-distance mosaics of Gould Mesa, a feature about 100 meters away from us (about 328 feet) that we’ll be driving to the south of as we continue to head toward the “boxwork” structures.

After a drive, there often aren’t many activities scheduled other than the imaging of our new location that we’ll need for the next planning day. However, in this plan ENV decided to take advantage of the fact that Navcam observations can take place at the same time that the rover is talking to one of the spacecraft that orbit Mars. This is a useful trick when power is tight as it allows us to do more science without adding additional awake time (since the rover needs to be awake anyway to communicate with the orbiters). Today, it’s being used to get some extra cloud observations right before sunset, a time that we don’t often get to observe. These observations include a zenith movie that looks straight up over the rover and a “phase function sky survey,” which takes a series of nine movies that form a dome around the rover to examine the properties of the clouds’ ice crystals. 

The second sol of this plan is much more relaxed, as post-drive sols often are because we don’t know exactly where we’ll be after a drive. Today, we’ve just got our usual ChemCam AEGIS activity, followed by a pair of Navcam cloud and cloud shadow movies to measure the altitude of clouds over Gale. As always, we’ve also got our usual set of REMS, RAD, and DAN activities throughout this plan.

The Earth Observer Editor’s Corner: January–March 2025

NASA’s Earth Observing fleet continues to age gracefully. While several new missions have joined the fleet in the past year, scientists and engineers work to extend the life of existing missions and maximize their science along the way. The crowning example is the first Earth Observing System (EOS) Flagship mission, Terra, which celebrated a quarter-century in orbit on December 18, 2024.

Terra continues to collect daily morning Earth observations using five different instruments: Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Clouds and the Earth’s Radiant Energy System (CERES), Multi-angle Imaging SpectroRadiometer (MISR), Moderate Resolution Imaging Spectroradiometer (MODIS), and Measurement of Pollution in the Troposphere (MOPITT). Collectively, these observations have established a robust satellite record of global scientific processes to track changes in temperature, glaciers, clouds, vegetation, land-use, air quality, and natural hazards such as hurricanes, wildfires, and volcanic eruptions.

Originally designed for a six-year prime mission, Terra continues to deliver data used by emergency managers, researchers, and modelers over a quarter-of-a-century later. On December 18th, 2024, NASA celebrated the 25th anniversary of Terra’s launch with a celebration at the Goddard Space Flight Center (GSFC) Visitor’s Center. NASA Senior management [from Headquarters and GSFC] as well as other key figures from Terra’s long history gave brief remarks and perspectives on Terra’s development and achievements. To read a review of the celebration, see “Celebrating 25 Years of Terra.”

Terra-related sessions (poster and oral) during the Fall American Geophysical Union (AGU) meeting were well-attended. The Terra team took advantage of the meeting to have a celebratory anniversary dinner that included attendees representing each of the five instruments.

Another mission to recently reach a longevity milestone is NASA’s Orbiting Carbon Observatory-2 (OCO-2), which celebrated 10 years in space last summer. OCO-2, which launched on July 2, 2014, from the Vandenburg Air Force (now Space Force) Base in California, was originally designed as a pathfinder mission to measure carbon dioxide (CO2) with the precision and accuracy needed to quantify where, when, and how the Earth inhales and exhales this important greenhouse gas seasonally. OCO-2 was part of the international Afternoon Constellation, or “A-Train,” which also included Aqua, Aura, CloudSat, and CALIPSO, as well as international partner missions.

Since its launch, OCO-2 data have revealed unprecedented insights into how the carbon cycle operates – from observing the impact and recovery of tropical land and ocean ecosystems during El Niño events to revealing the outsized impacts of extreme events (e.g., floods, droughts, and fires) on ecosystem health and functioning. Researchers from around the world use OCO-2 data, opening new opportunities for understanding the response of the carbon cycle to human-driven perturbations, such as the impact of COVID lockdowns on atmospheric CO2 and improved quantification of emissions from large power plants and cities.

OCO-2 also maps vegetation fluorescence, which shows promise as a reliable early warning indicator of flash drought. During photosynthesis, plants “leak” unused photons, producing a faint glow known as solar-induced fluorescence (SIF). The stronger the fluorescence, the more CO2 a plant is taking from the atmosphere to power its growth. Ancillary SIF measurements from OCO-2 will help scientists better predict flash droughts, and understand how these impact carbon emissions.

Ten years into the mission, OCO-2 has become the gold standard for CO2 measurements from space. The spacecraft and instrument continue to perform nominally, producing data leading to new scientific discoveries.

OCO–3, built from spare parts during the build of OCO-2 and launched to the International Space Station (ISS) in 2019, also celebrated a milestone, marking five years in orbit on May 4, 2024. While the follow-on has the same instrument sensitivity and makes essentially the same measurements as OCO-2, the precessing vantage point on the ISS (as opposed to OCO-2’s polar orbit) and the use of a new pointing mirror assembly (PMA) results in significant day-to-day spatial and temporal sampling differences that allows CO2 tracking for diurnal variability. In addition, the flexible PMA system allows for a much more dynamic observation-mode schedule.

Further out in space, about 1 million mi (~1.1 million km) from Earth, orbiting the “L1” Lagrange point between Earth and Sun, the Deep Space Climate Observatory (DSCOVR) celebrated the 10th anniversary of its launch on February 11, 2025. The two NASA Earth observing instruments on DSCOVR are the Earth Polychromatic Camera (EPIC) and National Institute of Standards and Technology (NIST) Advanced Radiometer [NISTAR].

The 10th DSCOVR EPIC NISTAR Science Team Meeting was held October 16–18, 2024 at Goddard Space Flight Center. Former U.S. Vice President Al Gore opened the meeting with remarks that focused on remote sensing and the future of Earth observations. Following Gore’s remarks, DSCOVR mission leadership and representatives from GSFC and the National Oceanic and Atmospheric Administration (NOAA) gave presentations on DSCOVR operations, EPIC calibration, and NISTAR Status and Science.

The meeting provided an opportunity for participants to learn the status of DSCOVR’s Earth-observing instruments, the status of recently released Level-2 (geophysical) data products, and the resulting science. As more people use DSCOVR data worldwide, the science team hopes to hear from users and team members at its next meeting. The latest updates from the mission can be found on the EPIC website. For more details, see the Summary of the 10th DSCOVR EPIC and NISTAR Science Team Meeting.

Flying in the space between satellites and ground-based observations, NASA’s Airborne Science Program operates a fleet of aircraft, unpiloted aerial vehicles, and even kites to study Earth and space science. Since 1987, a highly modified McDonnell Douglas DC-8 aircraft has been a mainstay of ASP’s fleet ­­– see Photo 1. The aircraft, located at NASA’s Armstrong Flight Research Center (AFRC) in California, flew countless missions as a science laboratory, producing science data for the national and global scientific communities. NASA decided to retire the venerable DC-8 aircraft, which made its last science flight in April 2024. The DC-8 is being replaced with a similarly refurbished Boeing 777 aircraft, which will be even more capable than the DC-8 and is located at the NASA Langley Research Center (LaRC).

The NASA History Office and NASA Earth Science Division cohosted a workshop, titled “Contributions of the DC-8 to Earth System Science at NASA,” on October 24–25, 2024 at the Mary W. Jackson NASA Headquarters (HQ) Building in Washington, DC – for more details on the DC-8 event, see the article The NASA DC-8 Retires: Reflections on its Contributions to Earth System Science.

There are also updates from three recent NASA field campaigns – where ground observations are timed and coordinated with aircraft flights (often at more than one altitude) and with satellite overpasses to gain a comprehensive (i.e., multilayered, multiscale) picture of the atmosphere over a certain area. 

The Westcoast & Heartland Hyperspectral Microwave Sensor Intensive Experiment (WHyMSIE) campaign was held from October 17- November 18, 2024. Serving as a future NASA planetary boundary-layer (PBL) mission prototype, WHyMSIE aimed to capture a wide variety of thermodynamic, moisture, and PBL regimes across a variety of surface types. WHyMSIE was an initial step towards an integrated and affordable PBL observing system of systems, with multiple observing nodes – i.e., space, suborbital, and ground – from passive and active sensors to enable a comprehensive and coherent picture of essential PBL variables and hydrometeors that is not possible with any single sensor, observational approach, or scale. As a partnership between NASA and NOAA, this field campaign flew a first-of-its-kind hyperspectral microwave airborne measurements (CoSMIR-H) that was complemented by other passive (thermal emission, solar reflectance) and active (lidar, radar) sensors flying onboard the NASA ER-2 (AFRC) and G-III (LaRC), with coordination over a variety of ground-based sensor facilities.

The GSFC Lidar Observation and Validation Experiment (GLOVE) was conducted in February 2025 at Edwards Air Force Base, California – see Photo 2. GLOVE flew the Cloud Physics Lidar (CPL), Roscoe lidar, enhanced MODIS Airborne Simulator (eMAS) imaging scanner, and Cloud Radar System (CRS) on the ER-2 to validate NASA ICESat-2 atmospheric data products and validate ESA’s recently launched EarthCARE lidar, radar, and spectrometer products.

NASA’s Earth Science Division FireSense project focuses on delivering NASA’s unique Earth science and technological capabilities to operational agencies, striving to address challenges in US wildland fire management. Together with agency, academic, and private partners, FireSense completed an airborne campaign in a wildfire smoke-impacted airshed in Missoula, MT on August 27–29, 2024. During the three-day campaign, a NASA Uninhabited Aerial System (UAS) team conducted eight data-collection flights, partnering these launches with weather balloon launches.

FireSense uses airborne campaigns to evaluate capabilities and technologies to support decision making in wildland fire management and air quality forecasting. Targeted data collection produces better forecasts and more successful technology transfer to wildland fire operations. In the future, the FireSense Program will coordinate two airborne campaigns for spring 2025 at Geneva State Forest, Alabama and Kennedy Space Center located within Merritt Island National Wildlife Refuge, Florida. Both 2025 campaigns will incorporate data collection before, during, and after prescribed fire operations. Beyond NASA, the campaign works in close partnership with the U.S. Forest Service, National Weather Service, U.S. Fish and Wildlife Service, Department of Defense, as well as partners in academia and the private sector. For more information on FireSense’s most recent campaign in Montana see the Editor’s Corner supplemental summary of “The FireSense Project.”

Congratulations to Jack Kaye, Associate Director for research with the Earth Science Division within NASA’s Science Mission Directorate, who has received the William T. Pecora Award for his vision and creative leadership in multidisciplinary Earth science research, as well as spurring advancements in the investigator community, supporting development of sensors, and shaping NASA satellite and aircraft missions and research programs at the highest levels. To read more about this accomplishment, see “Kaye Honored with Pecora Award.

On the outreach front, AGU returned to Washington, DC, for its annual meeting from December 9–14, 2024. NASA continued to uphold its long-standing tradition as an AGU partner and exhibitor, leveraging the meeting as an opportunity to share the agency’s cutting-edge research, data, and technology with the largest collection of Earth and planetary science professionals in the world. Many of the estimated 25,000 students, scientists, and industry personnel who attended the conference visited the NASA Science exhibit, interacting with NASA subject matter experts and listening to Hyperwall presentations throughout the week.

As the final event in a busy calendar of annual scientific conferences, AGU is often an opportunity for NASA scientists to publish findings from the previous year and set goals for the year ahead. The agency’s robust portfolio of missions and programs will continue to set new records, such as NASA’s Parker Solar Probe pass of the Sun, and conduct fundamental research in Earth and space science. To read more about AGU 2024, see the article: AGU 2024: NASA Science on Display in the Nation’s Capital.

Ending on a somber note, we recently posted three notable obituaries. Each of these individuals made significant contributions to EOS history, which are highlighted in the In Memoriam articles linked below.
