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.

Researchers utilizing publicly available Synthetic Aperture Radar (SAR) data from Capella Space and Umbra have uncovered significant hidden structures within and beneath the CFR Pyramid on the Giza Plateau. The study reveals five distinct "Zed" structures located above what was previously believed to be the pharaoh’s burial chamber, resembling similar formations found in the Khufu Pyramid. These structures are connected by geometric pathways, with additional secondary formations identified through satellite imaging.

Most notably, eight vertically aligned cylindrical structures, arranged in two parallel rows from north to south, extend 648 meters underground. These formations merge into two massive cubic structures, each approximately 80 meters per side. Tomographical analysis indicates that the cylindrical structures function as hollow wells surrounded by descending spiral pathways.
Further research suggests that these subterranean formations are not limited to the CFR Pyramid but extend beneath the Khufu and Menkaure pyramids as well, reaching depths of approximately two kilometers. The study marks a groundbreaking advancement in the understanding of the Giza Plateau’s underground complexity,
The discoveries surrounding the CFR Pyramid represent just the tip of a vast and complex structure beneath the Giza Plateau.If confirmed, this discovery could challenge mainstream Egyptology’s belief that the pyramids were simply royal tombs.

NASA/Brandon Torres Navarrete Engineers at NASA’s Ames Research Center in California’s Silicon Valley, Bohdan Wesely, right, and Eli Hiss, left, complete a fit check of the two halves of a space capsule that will study the clouds of Venus for signs of life.
Led by Rocket Lab of Long Beach, California, and their partners at the Massachusetts Institute of Technology in Cambridge, Rocket Lab’s Venus mission will be the first private mission to the planet.
NASA’s role is to help the commercial space endeavor succeed by providing expertise in thermal protection of small spacecraft. Invented at Ames, NASA’s Heatshield for Extreme Entry Environment Technology (HEEET) – the brown, textured material covering the bottom of the capsule in this photo – is a woven heat shield designed to protect spacecraft from temperatures up to 4,500 degrees Fahrenheit. The probe will deploy from Rocket Lab’s Photon spacecraft bus, taking measurements as it descends through the planet’s atmosphere.
Teams at Ames work with private companies, like Rocket Lab, to turn NASA materials into solutions such as the heat shield tailor-made for this spacecraft destined for Venus, supporting growth of the new space economy. NASA’s Small Spacecraft Technology program, part of the agency’s Space Technology Mission Directorate, supported development of the heat shield for Rocket Lab’s Venus mission.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid.
NASA’s Lucy spacecraft’s first views of the asteroid Donaldjohanson. The asteroid is circled on the left to guide the eye.NASA/Goddard/SwRI/Johns Hopkins APL Lucy will pass within 596 miles (960 km) of the 2-mile-wide asteroid on April 20. This second asteroid encounter for the Lucy spacecraft will serve as a dress-rehearsal for the spacecraft’s main targets, the never-before-explored Jupiter Trojan asteroids. Lucy already successfully observed the tiny main belt asteroid Dinkinesh and its contact-binary moon, Selam, in November 2023. Lucy will continue to image Donaldjohanson over the next two months as part of its optical navigation program, which uses the asteroid’s apparent position against the star background to ensure an accurate flyby.
Donaldjohanson will remain an unresolved point of light during the spacecraft’s long approach and won’t start to show surface detail until the day of the encounter.
From a distance of 45 million miles (70 million km), Donaldjohanson is still dim, though it stands out clearly in this field of relatively faint stars in the constellation of Sextans. Celestial north is to the right of the frame, and the 0.11-degree field of view would correspond to 85,500 miles (140,000 km) at the distance of the asteroid. In the first of the two images, another dim asteroid can be seen photobombing in the lower right quadrant of the image. However, just as the headlights of an approaching car often appear relatively stationary, Donaldjohanson’s apparent motion between these two images is much smaller than that of this interloper, which has moved out of the field of view in the second image.
These observations were made by Lucy’s high-resolution camera, the L’LORRI instrument — short for Lucy LOng Range Reconnaissance Imager — provided by the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.
Asteroid Donaldjohanson is named for anthropologist Donald Johanson, who discovered the fossilized skeleton — called “Lucy” — of a human ancestor. NASA’s Lucy mission is named for the fossil.
Lucy’s principal investigator, Hal Levison, is based out of the Boulder, Colorado, branch of Southwest Research Institute, headquartered in San Antonio. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and safety and mission assurance. Lockheed Martin Space in Littleton, Colorado, built the spacecraft. Lucy is the 13th mission in NASA’s Discovery Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Discovery Program for the Science Mission Directorate at NASA Headquarters in Washington.
