This near-infrared image released on May 6, 2026, shows a section of one of the spiral arms of Messier 51 (M51). M51 is one of four nearby galaxies observed by NASA’s James Webb Space Telescope in a study of nearly 9,000 star clusters.
Data from the study shows that more massive star clusters emerge more quickly from the clouds they are born in. Learning about star formation helps us understand galactic evolution, the dynamics within a galaxy, as well as how and where planets form.

From high‑speed research flights to high‑altitude science campaigns, NASA depends on aircraft that perform at their best and the ground crews who keep them mission ready.
At NASA’s Armstrong Flight Research Center in Edwards, California, specially trained maintenance crews are essential to keeping the agency’s aircraft flying safely and reliably.
This year, NASA added two F-15s and a Pilatus PC-12 to its fleet at Armstrong. These aircraft – alongside platforms such as the high-altitude ER-2s and NASA’s newest X-plane, the X-59 – reflect a wide range of capabilities. The maintenance staff is responsible for keeping each one mission ready.

“That’s the beauty of our Armstrong maintenance teams. They adapt to any type of change,” said Jose “Manny” Rodriguez, NASA Armstrong Gulfstream G-IV crew chief. “One day you could have an instrument being loaded, and the next day it may be aircraft reconfiguration, all while other aircraft systems may need fixing. They adapt and they overcome any situation.”
Each aircraft supports a specific mission, whether it’s conducting science research, serving as a support or chase aircraft, or assisting NASA rocket launches. The aircraft fly at different speeds, carry specialized hardware, and require maintenance crews to stay agile with fast-paced changes.
To ensure NASA can make aeronautics and science advancements safely, the crews work continuously, checking on the ejection seats, filling the tanks with fuel, and changing out brakes, wheels, wiring, and hardware constantly, all of which can degrade with each flight.
On any given day, an aircraft may be flight-ready for a mission, undergoing scheduled maintenance or modifications, or down for longer-term care.
There are typically multiple NASA Armstrong aircraft in the air in one day. Currently, the center’s C-20A is flying in Peru and Panama, the X-59 is often flying twice per day with a chase plane, and the center’s ER-2 is flying in Colorado, supporting the Geological Earth Mapping Experiment (GEMx). All this work is happening at the same time, and Armstrong’s skilled maintenance staff is prepping and fixing aircraft as needed along the way.
The team includes mechanics with both military and civilian backgrounds, and the job involves a lot of on-the-job training.
Maintenance crews are composed of:
After the maintenance crew ensures the aircraft is in the best condition possible, the team tows it out to the flightline, and it becomes ready for operations. The NASA pilot assigned to the mission will walk around the aircraft with the assigned crew chief for a final safety check before flight.
“There is a crew chief assigned to every aircraft,” Rodriguez said. “The crew chief is responsible for the integrity of that aircraft, and at the end of the day, his signature and the pilot’s together are what constitutes that the aircraft is safe for flight.”
Maintenance crews track each flight to help ensure it completes the mission without returning early. If an aircraft does return to base early, the maintenance team stands ready. When it lands, the crew is right there again, helping the research team complete the mission and fixing whatever is needed to stay nimble and ready for the next flight.
“It’s difficult at times to work with different airplanes from both the civilian and military sides, but it’s very rewarding to see that we have the capability and the expertise to keep these aircraft flying,” Rodriguez said.

NASA announced plans Friday to compete the next contract for managing and operating the agency’s federally funded research and development center (FFRDC) in Southern California at the Jet Propulsion Laboratory (JPL), to ensure continued accountability and strong value for U.S. taxpayers.
The California Institute of Technology (Caltech) has managed the laboratory since its inception in the 1930s, and previous NASA contracts for its management and operations have been awarded sole source to the university since the facility was transferred from the U.S. Army to NASA in 1958.
The rapid growth of the U.S. space economy indicates there may now be a viable competitive market for programmatic and institutional elements of the FFRDC operations.
Conducting a competition for this contract enables NASA to assess the potential benefits of alternative management approaches to the FFRDC, including opportunities to enhance mission performance, innovation, and overall cost and operational efficiency, consistent with federal competition requirements.
This decision is part of a broader governmentwide and agency effort to find efficiencies, strengthen performance, and drive mission outcomes faster and more affordably.
“The Jet Propulsion Laboratory has delivered some of the most extraordinary scientific and engineering achievements in NASA’s history,” said NASA Administrator Jared Isaacman. “As America’s space economy evolves, we have a responsibility to the American people and the scientific community to evaluate how we can execute faster, operate more efficiently, and continue to deliver world-class science and engineering at the highest level. The decision to compete this contract reflects NASA’s commitment to strong stewardship of taxpayer resources and positions Jet Propulsion Laboratory to continue driving world-changing scientific discovery and technological innovation for decades to come.”
The work conducted at JPL remains critically important to the agency, and NASA is committed to maintaining continuity for active and future missions throughout the procurement process. NASA also is committed to maintaining the FFRDC’s existing physical location.
This approach is consistent with broader government practices, including at the Department of Energy, which has held full and open competitions for five of its 16 FFRDC management and operations contracts over the past 10 years.
The current contract with Caltech began Oct. 1, 2018, and runs through Sept. 30, 2028, with a potential maximum value of $30 billion, if all options are exercised. NASA has initiated the procurement process to compete the contract. Beginning this process now allows the agency sufficient time to conduct a comprehensive competition and award cycle while maintaining continuity for ongoing missions and laboratory operations.

Editor’s Note: This advisory was updated May 22, 2026 to include a retirement.
NASA announced Friday an agencywide realignment to increase mission focus and move out on the National Space Policy. These changes position the agency to better deliver on the nation’s highest‑priority objectives with speed and efficiency.
During the Ignition event in late March, NASA Administrator Jared Isaacman and agency leaders outlined the most pressing objectives to deliver on the next chapter of American leadership in space. President Trump’s Executive Order Ensuring American Space Superiority, otherwise known as the National Space Policy, directed NASA to focus talent and resources on objectives including accelerating the Artemis program, establishing a Moon Base, developing a nuclear space reactor, igniting the orbital economy, and expanding missions of science and discovery.
To support the agency’s ambitious short- and long-term goals, NASA is taking action to increase specialization at centers and integrate mission directorates, elevating delivery of technically excellent work. Some of these actions include:
“This initiative reflects NASA’s extreme focus on executing the mission in direct support of the National Space Policy. We are focusing resources on the most pressing objectives only NASA is capable of undertaking and liberating the workforce from unnecessary bureaucracy and obstacles that impede progress. We aim to rebuild competencies and instill a culture that attracts the best and brightest capable of pursuing the most demanding engineering challenges and moving safely and urgently,” said Isaacman. “There will be no reduction in force, no program cancellations, no closures, but we will achieve cost savings through more efficient execution and taking an active role in delivering the outcomes the world has been waiting for from NASA. This is how we deliver on the mission, meet the moment, and continue to make history on behalf of the American people.”
Mission directorate realignment is as follows:
Additional leadership roles, in alphabetical order, include:
Leadership at unlisted centers remains unchanged.

A material recently discovered and tested at NASA’s Glenn Research Center in Cleveland could help astronauts pack lighter for future missions to the Moon. NASA is researching ways explorers could “live off the land” by harnessing lunar resources, including melting Moon rocks to extract metals for building infrastructure and oxygen for fuel and life support.
As part of a graduate fellowship through the agency’s Space Technology Graduate Research Opportunities, Dr. Kevin Yu, who now works as a technologist at NASA’s Jet Propulsion Laboratory in Southern California, teamed up with Dr. Jamesa Stokes, a materials research engineer at NASA Glenn, to study how a variety of substances interacted with liquefied Moon dust.

About six months into their research, Stokes and Yu realized they’d stumbled across something promising and entirely new. After combining simulated lunar dust with a compound called scandium oxide and heat treating the mixture using a red-hot furnace, they discovered that an unknown material had formed. The researchers checked and double-checked their work, but the material didn’t match any of the more than 1 million substances in their X-ray analysis database.

Nothing about the material had ever been studied before, so the team started from scratch, measuring the substance’s chemical composition. To make small, isolated samples and continue testing how it reacted with molten Moon dust, they used special grinding and mixing equipment in their laboratory to crush up around eight basic oxide components in ethyl alcohol before baking the mixture at more than 2,900 degrees Fahrenheit inside the furnace.
“It’s actually a very cool-looking powder; it goes in pink, almost like strawberry milk,” Yu said. “It has a built-in color indicator, so by the time you’re done with it, it turns to a light beige or tan color, and that’s how you know the reaction has proceeded the way you wanted it to.”

After analyzing their results, the team found that the new substance isn’t corroded too quickly by the molten Moon dirt and can withstand the high temperatures needed to melt it — up to six times hotter than the oven in your kitchen. While it’s made with scandium oxide, which can be expensive, it costs much less than precious metals like platinum that would normally be used in these types of high-temperature processes.
The researchers’ insights could help influence NASA’s designs for a future technology that would extract resources from Moon rocks, and the new material could be used to make the pipes or basins holding molten dust inside this potential technology.
The new material’s characteristics also could prove ideal for making coatings that protect parts inside of jet engines, which can reach similarly scorching temperatures. The researchers found it is lighter, less dense, and better at insulating heat than current state-of-the-art coating materials.
While Yu and Stokes have now completed their initial tests, they hope to fine-tune the material in the future to purify it and make it even more affordable to produce. Materials research will be integral to exploring the harsh environments of the Moon and beyond.

Studying new materials also advances NASA’s work on Earth.
“I think trying to push what’s possible with materials also allows for a lot of breakthroughs on the terrestrial side. Having a better understanding of materials for all sorts of applications is what gets me excited to go to work in the morning,” Yu said. “That’s why I love NASA’s mission; it’s for the benefit of all.”
