The tentative discovery hints at an habitat where life could potentially thrive.

A big rover makes a big find on Mars. Little rovers have their place in exploration, too.

A single 3.5 billion-year-old rock shows signs of all the conditions life needs to thrive.

If passed, it would be the first standalone NASA authorization since 2017.

From the dangers of radiation to the complications of landing a crewed spacecraft, there are myriad technical challenges facing human exploration of Mars.

NASA and ESA have signed a partnership agreement to get the ExoMars Rosalind Franklin rover down to the surface of Mars, getting the mission back on track after geopolitical factors delayed it.

This week brings updates on the next missions to rove — and maybe even fly — over the surface of Mars.

Twenty years ago, a Planetary Society program sent students to NASA's Jet Propulsion Laboratory to work on the Mars Exploration Rovers program.

The project has the potential to transform our understanding of the Solar System and provide evidence of life beyond Earth.

Though promising conceptually, Starship presents more questions than answers for NASA's Mars Sample Return needs.

At 12:05 p.m. EDT, the unpiloted SpaceX Dragon spacecraft undocked from the zenith, or space-facing, port of the International Space Station’s Harmony module following a command from ground controllers at SpaceX.

NASA’s live coverage of undocking and departure of the agency’s SpaceX 32nd commercial resupply services mission is underway on NASA+. Learn how to watch NASA content through a variety of platforms.

NASA and SpaceX now are targeting 12:05 p.m. EDT Friday, May 23, for the undocking of company’s 32nd commercial resupply services mission from the International Space Station. Live coverage of Dragon spacecraft undocking and departure begins at 11:45 a.m. on NASA+. Mission teams will continue to review weather conditions off the coast of California ahead of Dragon's departure from the orbital complex.

The SpaceX Dragon cargo spacecraft will wait one more day before departing the International Space Station as mission managers monitor weather conditions at its splashdown site off the coast of California. Meanwhile, the Expedition 73 crew eased its cargo loading activities and focused on ongoing microgravity research to improve health on and off the Earth.

NASA and SpaceX are standing down from Thursday’s undocking opportunity of Dragon, filled with science, from the International Space Station. Mission teams will continue to review weather conditions off the coast of California, which currently are not favorable for splashdown operations, and set a new target opportunity for the return of SpaceX’s 32nd commercial resupply services mission for NASA.
