The European Space Agency (ESA) has powered down its Gaia spacecraft after more than a decade spent gathering data that are now being used to unravel the secrets of our home galaxy.
On 27 March 2025, Gaia’s control team at ESA’s European Space Operations Centre carefully switched off the spacecraft’s subsystems and sent it into a ‘retirement orbit’ around the Sun.
Though the spacecraft’s operations are now over, the scientific exploitation of Gaia’s data has just begun.

The innovative team of engineers and scientists from NASA, the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and more than 40 other partner organizations across the country that created the Parker Solar Probe mission has been awarded the 2024 Robert J. Collier Trophy by the National Aeronautic Association (NAA). This annual award recognizes the most exceptional achievement in aeronautics and astronautics in America with respect to improving the performance, efficiency, and safety of air or space vehicles in the previous year.
“Congratulations to the entire Parker Solar Probe team for this well-earned recognition,” said NASA acting Administrator Janet Petro. “This mission’s trailblazing research is rewriting the textbooks on solar science by going to a place no human-made object has ever been and advancing NASA’s efforts to better understand our solar system and the Sun’s influence, with lasting benefits for us all. As the first to touch the Sun and fastest human-made object ever built, Parker Solar Probe is a testament to human ingenuity and discovery.”
An artist’s concept of NASA’s Parker Solar Probe. NASA On Dec. 24, 2024, Parker Solar Probe made its closest approach to the Sun, passing deep within the Sun’s corona, just 3.8 million miles above the Sun’s surface and at a top speed of close to 430,000 mph, ushering in a new era of scientific discovery and space exploration.
“This award is a recognition of the unrelenting dedication and hard work of the Parker Solar Probe team. I am so proud of this team and honored to have been a part of it,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “By studying the Sun closer than ever before, we continue to advance our understanding of not only our closest star, but also stars across our universe. Parker Solar Probe’s historic close approaches to the Sun are a testament to the incredible engineering that made this record-breaking journey possible.”
Three novel aerospace technology advancements were critical to enabling this record performance: The first is the Thermal Protection System, or heat shield, that protects the spacecraft and is built to withstand brutal temperatures as high as 2,500 degrees Fahrenheit. The Thermal Protection System allows Parker’s electronics and instruments to operate close to room temperature.
Additional Parker innovations included first-of-their-kind actively cooled solar arrays that protect themselves from overexposure to intense solar energy while powering the spacecraft, and a fully autonomous spacecraft system that can manage its own flight behavior, orientation, and configuration for months at a time. Parker has relied upon all of these vital technologies every day since its launch almost seven years ago, in August 2018.
“I am thrilled for the Parker Solar Probe team on receiving this well-deserved award,” said Joe Westlake, director of the Heliophysics Division at NASA Headquarters. “The new information about the Sun made available through this mission will improve our ability to prepare for space weather events across the solar system, as well as better understand the very star that makes life possible for us on Earth.”
Parker’s close-up observations of solar events, such as coronal mass ejections and solar particle events, are critical to advancing our understanding of the science of our Sun and the phenomena that drive high-energy space weather events that pose risks to satellites, air travel, astronauts, and even power grids on Earth. Understanding the fundamental physics behind events which drive space weather will enable more reliable predictions and lower astronaut exposure to hazardous radiation during future deep space missions to the Moon and Mars.
“This amazing team brought to life an incredibly difficult space science mission that had been studied, and determined to be impossible, for more than 60 years. They did so by solving numerous long-standing technology challenges and dramatically advancing our nation’s spaceflight capabilities,” said APL Director Ralph Semmel. “The Collier Trophy is well-earned recognition for this phenomenal group of innovators from NASA, APL, and our industry and research partners from across the nation.”
First awarded in 1911, the Robert J. Collier Trophy winner is selected by a group of aviation leaders chosen by the NAA. The Collier Trophy is housed in the Smithsonian’s National Air and Space Museum in Washington.
“Traveling three times closer to the Sun and seven times faster than any spacecraft before, Parker’s technology innovations enabled humanity to reach inside the Sun’s atmosphere for the first time,” said Bobby Braun, head of APL’s Space Exploration Sector. “We are all immensely proud that the Parker Solar Probe team will join a long legacy of prestigious aerospace endeavors that redefined technology and changed history.”
“The Parker Solar Probe team’s achievement in earning the 2024 Collier is a shining example of determination, genius, and teamwork,” said NAA President and CEO Amy Spowart. “It’s a distinct honor for the NAA to acknowledge and celebrate the remarkable team that turned the impossible into reality.”
Parker Solar Probe was developed as part of NASA’s Living With a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living With a Star program is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, for NASA’s Science Mission Directorate in Washington. The Applied Physics Laboratory designed, built, and operates the spacecraft and manages the mission for NASA.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This artist’s concept shows astronauts working on the Moon alongside different technology systems. The Data & Reasoning Fabric technology could help these systems operate in harmony, supporting the astronauts and ground control on Earth.Credit: NASA Imagine your car is in conversation with other traffic and road signals as you travel. Those conversations help your car anticipate actions you can’t see: the sudden slowing of a truck as it begins to turn ahead of you, or an obscured traffic signal turning red. Meanwhile, this system has plotted a course that will drive you toward a station to recharge or refuel, while a conversation with a weather service prepares your windshield wipers and brakes for the rain ahead.
This trip requires a lot of communication among systems from companies, government agencies, and organizations. How might these different entities – each with their own proprietary technology – share data safely in real time to make your trip safe, efficient, and enjoyable?
Technologists at NASA’s Ames Research Center in California’s Silicon Valley created a framework called Data & Reasoning Fabric (DRF), a set of software infrastructure, tools, protocols, governance, and policies that allow safe, secure data sharing and logical prediction-making across different operators and machines. Originally developed with a focus on providing autonomous aviation drones with decision-making capabilities, DRF is now being explored for other applications.
This means that one day, DRF-informed technology could allow your car to receive traffic data safely and securely from nearby stoplights and share data with other vehicles on the road. In this scenario, DRF is the choreographer of a complex dance of moving objects, ensuring each moves seamlessly in relation to one another towards a shared goal. The system is designed to create an integrated environment, combining data from systems that would otherwise be unable to interact with each other.
“DRF is built to be used behind the scenes,” said David Alfano, chief of the Intelligent Systems Division at Ames. “Companies are developing autonomous technology, but their systems aren’t designed to work with technology from competitors. The DRF technology bridges that gap, organizing these systems to work together in harmony.”
Traffic enhancements are just one use case for this innovative system. The technology could enhance how we use autonomy to support human needs on Earth, in the air, and even on the Moon.
Supporting Complex Logistics
To illustrate the technology’s impact, the DRF team worked with the city of Phoenix on an aviation solution to improve transportation of critical medical supplies from urban areas out to rural communities with limited access to these resources. An autonomous system identified where supplies were needed and directed a drone to pick up and transport supplies quickly and safely.
“All the pieces need to come together, which takes a lot of effort. The DRF technology provides a framework where suppliers, medical centers, and drone operators can work together efficiently,” said Moustafa Abdelbaky, senior computer scientist at Ames. “The goal isn’t to remove human involvement, but help humans achieve more.”
The DRF technology is part of a larger effort at Ames to develop concepts that enable autonomous operations while integrating them into the public and commercial sector to create safer, efficient environments.
“At NASA, we’re always learning something. There’s a silver lining when one project ends, you can identify a new lesson learned, a new application, or a new economic opportunity to continue and scale that work,” said Supreet Kaur, lead systems engineer at Ames. “And because we leverage all of the knowledge we’ve gained through these experiments, we are able to make future research more robust.”
Choreographed Autonomy
Industries like modern mining involve a variety of autonomous and advanced vehicles and machinery, but these systems face the challenge of communicating sufficiently to operate in the same area. The DRF technology’s “choreography” might help them work together, improving efficiency. Researchers met with a commercial mining company to learn what issues they struggle with when using autonomous equipment to identify where DRF might provide future solutions.
“If an autonomous drill is developed by one company, but the haul trucks are developed by another, those two machines are dancing to two different sets of music. Right now, they need to be kept apart manually for safety,” said Johnathan Stock, chief scientist for innovation at the Ames Intelligent Systems Division. “The DRF technology can harmonize their autonomous work so these mining companies can use autonomy across the board to create a safer, more effective enterprise.”
Further testing of DRF on equipment like those used in mines could be done at the NASA Ames Roverscape, a surface that includes obstacles such as slopes and rocks, where DRF’s choreography could be put to the test.
Stock also envisions DRF improving operations on the Moon. Autonomous vehicles could transport materials, drill, and excavate, while launch vehicles come and go. These operations will likely include systems from different companies or industries and could be choreographed by DRF.
As autonomous systems and technologies increase across markets, on Earth, in orbit, and on the Moon, DRF researchers are ready to step on the dance floor to make sure everything runs smoothly.
“When everyone’s dancing to the same tune, things run seamlessly, and more is possible.”
