NASA’s Mars Reconnaissance Orbiter (MRO) officially went into service above the Red Planet in November 2006. The spacecraft has since spent nearly 20 years circling Earth’s closest neighbor, studying its geology and identifying icy evidence of a once watery world.

The one-minute timelapse shows the rover traverse the Martian terrain, and cross its own tracks from earlier in the year.

Lawmakers defended NASA research efforts Wednesday at a hearing on President Donald Trump's choice to lead the space agency.

NASA reported 2025 achievements in lunar, Mars, and Earth science missions, including Artemis II preparations, CLPS landers, Mars ESCAPADE, ISS research, heliophysics, and new astronaut candidates.

By May, that uncertainty turned to dread as the administration released its proposed budget for fiscal year 2026, one that featured steep cuts at NASA and other science agencies. That’s where Casey Dreier of The Planetary Society stepped in.

The United States space agency has pioneered planetary science technologies as the world's leader in climate research for more than 40 years, but that may be about to change. NASA's acting Administrator Sean Duffy says the agency will step back from ...
