Preparations for Next Moonwalk Simulations Underway (and Underwater)
The G-IV aircraft flies overhead in the Mojave Desert near NASA’s Armstrong Flight Research Center in Edwards, California. Baseline flights like this one occurred in June 2024, and future flights in service of science research will benefit from the installment of the Soxnav navigational system, developed in collaboration with NASA’s Jet Propulsion Laboratory in Southern California and the Bay Area Environmental Research Institute in California’s Silicon Valley. This navigational system provides precise, economical aircraft guidance for a variety of aircraft types moving at high speeds.NASA/Carla Thomas NASA and its partners recently tested an aircraft guidance system that could help planes maintain a precise course even while flying at high speeds up to 500 mph. The instrument is Soxnav, the culmination of more than 30 years of development of aircraft navigation systems.
NASA’s G-IV aircraft flew its first mission to test this navigational system from NASA’s Armstrong Flight Research Center in Edwards, California, in December 2024. The team was composed of engineers from NASA Armstrong, NASA’s Jet Propulsion Laboratory in Southern California, and the Bay Area Environmental Research Institute (BAERI) in California’s Silicon Valley.
“The objective was to demonstrate this new system can keep a high-speed aircraft within just a few feet of its target track, and to keep it there better than 90% of the time,” said John Sonntag, BAERI independent consultant co-developer of Soxnav.
With 3D automated steering guidance, Soxnav provides pilots with a precision approach aid for landing in poor visibility. Previous generations of navigational systems laid the technical baseline for Soxnav’s modern, compact, and automated iteration.
“The G-IV is currently equipped with a standard autopilot system,” said Joe Piotrowski Jr., operations engineer for the G-IV. “But Soxnav will be able to create the exact level flight required for Next Generation Airborne Synthetic Aperture Radar (AirSAR-NG) mission success.”
Jose “Manny” Rodriguez adjusts the Soxnav instrument onboard the G-IV aircraft in December 2024. As part of the team of experts, Rodriguez ensures that the electronic components of this instrument are installed efficiently. His expertise will help bring the innovative navigational guidance of the Soxnav system to the G-IV and the wider airborne science fleet at NASA. Precision guidance provided by the Soxnav enables research aircraft like the G-IV to collect more accurate, more reliable Earth science data to scientists on the ground.NASA/Steve Freeman Guided by Soxnav, the G-IV may be able to deliver better, more abundant, and less expensive scientific information. For instance, the navigation tool optimizes observations by AirSAR-NG, an instrument that uses three radars simultaneously to observe subtle changes in the Earth’s surface. Together with the Soxnav system, these three radars provide enhanced and more accurate data about Earth science.
“With the data that can be collected from science flights equipped with the Soxnav instrument, NASA can provide the general public with better support for natural disasters, tracking of food and water supplies, as well as general Earth data about how the environment is changing,” Piotrowski said.
Ultimately, this economical flight guidance system is intended to be used by a variety of aircraft types and support a variety of present and future airborne sensors. “The Soxnav system is important for all of NASA’s Airborne Science platforms,” said Fran Becker, project manager for the G-IV AirSAR-NG project at NASA Armstrong. “The intent is for the system to be utilized by any airborne science platform and satisfy each mission’s goals for data collection.”
In conjunction with the other instruments outfitting the fleet of airborne science aircraft, Soxnav facilitates the generation of more abundant and higher quality scientific data about planet Earth. With extreme weather events becoming increasingly common, quality Earth science data can improve our understanding of our home planet to address the challenges we face today, and to prepare for future weather events.
“Soxnav enables better data collection for people who can use that information to safeguard and improve the lives of future generations,” Sonntag said.

Credit: NASA The Aerospace Safety Advisory Panel (ASAP), an advisory committee that reports to NASA and Congress, issued its 2024 annual report Thursday examining the agency’s safety performance, accomplishments, and challenges during the past year.
The report highlights 2024 activities and observations on NASA’s work, including:
strategic vision and agency governance Moon to Mars management future of U.S. presence in low Earth orbit health and medical risks in human space exploration “Over the past year, NASA has continued to make meaningful progress toward meeting the intent of the broad-ranging recommendations the panel has made over the last several years,” said retired U.S. Air Force Lt. Gen. Susan J. Helms, chair of ASAP. “We believe that the agency’s careful attention to vision, strategy, governance, and program management is vital to the safe execution of NASA’s complex and critical national mission.”
This year’s report reflects the panel’s continued focus on NASA’s strategies for risk management and safety culture in an environment of growing space commercialization. Specifically, the panel cites its 2021 recommendations for NASA on preparing for future challenges in a changing landscape, including the need to evaluate NASA’s approach to safety and technical risk and to evolve its role, responsibilities, and relationships with private sector and international partners.
Overall, the panel finds NASA is continuing to make progress with respect to the agency’s strategic vision, approach to governance, and integrated program management. The NASA 2040 new agencywide initiative is working to operationalize the agency’s vision and strategic objectives across headquarters and centers. With the establishment of NASA’s Moon to Mars Program Office in 2023, it finds NASA has implemented safety and risk management as a key focus for NASA’s Artemis campaign.
The 2024 report provides details on the concrete actions the agency should take to fulfill its previous recommendations and spotlights its recommendations for the agency moving ahead. It addresses safety assessments for Moon to Mars and current International Space Station operations, as well as risk-related issues surrounding NASA’s planned transition to commercial low Earth orbit destinations.
It covers relevant areas of human health and medicine in space and the impact of budget constraints and uncertainty on safety.
The annual report is based on the panel’s 2024 fact-finding and quarterly public meetings; direct observations of NASA operations and decision-making; discussions with NASA management, employees, and contractors; and the panel members’ experiences.
Congress established the panel in 1968 to provide advice and make recommendations to the NASA administrator on safety matters after the 1967 Apollo 1 fire claimed the lives of three American astronauts.

NASA CubeSat Finds New Radiation Belts After May 2024 Solar Storm
Key Points
The May 2024 solar storm created two new temporary belts of high-energy particles surrounding Earth. Such belts have been seen before, but the new ones were particularly long lasting, especially the new proton belt. The findings are particularly important for spacecraft launching into geostationary orbits, which can be damaged as they traverse the dangerous belts. The largest solar storm in two decades hit Earth in May 2024. For several days, wave after wave of high-energy charged particles from the Sun rocked the planet. Brilliant auroras engulfed the skies, and some GPS communications were temporarily disrupted.
With the help of a serendipitously resurrected small NASA satellite, scientists have discovered that this storm also created two new temporary belts of energetic particles encircling Earth. The findings are important to understanding how future solar storms could impact our technology.
The new belts formed between two others that permanently surround Earth called the Van Allen Belts. Shaped like concentric rings high above Earth’s equator, these permanent belts are composed of a mix of high-energy electrons and protons that are trapped in place by Earth’s magnetic field. The energetic particles in these belts can damage spacecraft and imperil astronauts who pass through them, so understanding their dynamics is key to safe spaceflight.
The May 2024 solar storm created two extra radiation belts, sandwiched between the two permanent Van Allen Belts. One of the new belts, shown in purple, included a population of protons, giving it a unique composition that hadn’t been seen before. NASA/Goddard Space Flight Center/Kristen Perrin The discovery of the new belts, made possible by NASA’s Colorado Inner Radiation Belt Experiment (CIRBE) satellite and published Feb. 6, 2025, in the Journal of Geophysical Research: Space Physics, is particularly important for protecting spacecraft launching into geostationary orbits, since they travel through the Van Allen Belts several times before reaching their final orbit.
New Belts Amaze Scientists
Temporary belts have been detected in the aftermath of large solar storms before. But while previous belts have been composed mostly of electrons, the innermost of the two new belts also included energetic protons. This unique composition is likely due to the strength and composition of the solar storm.
“When we compared the data from before and after the storm, I said, ‘Wow, this is something really new,’” said the paper’s lead author Xinlin Li, a professor at the Laboratory for Atmospheric and Space Physics (LASP) and Department of Aerospace Engineering Sciences at the University of Colorado Boulder. “This is really stunning.”
The new belts also seem to have lasted much longer than previous belts. Whereas previous temporary belts lasted around four weeks, the new belt composed primary of electrons lasted more than three months. The other belt, that also includes protons, has lasted much longer than the electron belt because it is in a more stable region and is less prone to the physical processes that can knock the particles out of orbit. It is likely still there today.
“These are really high-energy electrons and protons that have found their way into Earth’s inner magnetic environment,” said David Sibeck, former mission scientist for NASA’s Van Allen Probes and research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who was not involved with the new study. “Some might stay in this place for a very long time.”
How long such belts stick around depends on passing solar storms. Large storms can provide the energy to knock particles in these belts out of their orbits and send them spiraling off into space or down to Earth. One such storm at the end of June significantly decreased the size of the new electron belt and another in August nearly erased the remainder of that electron belt, though a small population of high-energy electrons endured.
CubeSat Fortuitously Comes Back to Life to Make the Discovery
The new discovery was made by NASA’s CIRBE satellite, a CubeSat about the size of a shoebox that circled the planet’s magnetic poles in a low Earth orbit from April 2023 to October 2024. CIRBE housed an instrument called the Relativistic Electron Proton Telescope integrated little experiment-2 (REPTile-2) — a miniaturized and upgraded version of an instrument that flew aboard NASA’s Van Allen Probes, which made the first discovery of a temporary electron belt in 2013.
The CIRBE CubeSat in the laboratory before launch. CIRBE was designed and built by LASP at the University of Colorado Boulder. Xinlin Li/LASP/CU Boulder After a year in space, the CubeSat experienced an anomaly and unexpectedly went quiet on April 15, 2024. The scientists were disappointed to miss the solar storm in May but were able to rely on other spacecraft to provide some preliminary data on the electron belt. Luckily, on June 15, the spacecraft sprang back to life and resumed taking measurements. The data provided high-resolution information that couldn’t be gleaned by any other instrument and allowed the scientists to understand the magnitude of the new belts.
“Once we resumed measurements, we were able to see the new electron belt, which wasn’t visible in the data from other spacecraft,” Li said.
Having the CubeSat in orbit to measure the effect of the solar storm has been bittersweet, Li said. While it provided the opportunity to measure the effects of such a large event, the storm also increased atmospheric drag on the CubeSat, which caused its orbit to decrease prematurely. As a result, the CubeSat deorbited in October 2024. However, the spacecraft’s data makes it all worth it.
“We are very proud that our very small CubeSat made such a discovery,” Li said.
CIRBE was designed and built by LASP at the University of Colorado Boulder and was launched through NASA’s CubeSat Launch Initiative (CSLI). The mission is sponsored by NASA’s Heliophysics Flight Opportunities for Research & Technology (H-FORT) program.

The post-government employment ethics statute, 18 U.S.C. § 207, applies to a former NASA employee’s communication with NASA or the Government on behalf of the former employee’s non-federal employer. Former NASA employees should contact a NASA ethics official for advice before communications or otherwise interacting with NASA or the Government on behalf of their new employer because this criminal statute may be implicated. The Procurement Integrity Act also restricts individuals who were in certain contracting roles from accepting compensated work from certain contractors for a limited period.
Contact Information
If you have questions, please ask an ethics official at your respective center.
Headquarters and Center Ethics Officials Special Government Employees
A Special Government Employee (SGE) is an officer or employee “who is retained, designated, appointed, or employed to perform, with or without compensation, for not to exceed one hundred and thirty days during any consecutive period of three hundred and sixty-five consecutive days.” 18 U.S.C. § 202. Congress created the SGE category in 1962 to allow the federal Government to obtain the expertise it needs, while allowing experts to continue their private professional lives. As a result, some of the ethics statutes and regulations apply differently to SGEs than they do to regular executive branch employees, and some provisions do not apply at all.
Financial Disclosure
SGEs are required to file a financial disclosure report each year, usually a confidential financial disclosure report (OGE-450). Financial disclosure reporting helps NASA identify any possible financial conflicts of interest. SGEs are notified in advance of when to file.
