In a groundbreaking observation, NASA’s Mars Odyssey orbiter captured an extraordinary image of a towering formation breaking through the Martian morning clouds. This formation, believed to be the peak of Arsia Mons,

Learn why scientists are cautiously optimistic about the potential biosignatures found in the Sapphire Canyon rock sample.

NASA scientists say a rock sample collected by the Perseverance rover in Jezero Crater may contain the strongest signs yet of ancient microbial life on Mars, though more analysis is needed before drawing firm conclusions.

NASA announces four CHAPEA volunteers for a year-long Mars simulation; the program will start in October Another chapter on Mars habitation is set to begin with a year-long simulation in Texas. This simulation will have four participants who will survive in a Martian environment,

NASA officials say its Mars-bound ESCAPADE spacecraft is back in Florida and is being prepped for its scheduled launch this fall.

NASA's Artemis II astronauts will embark on the first crewed U.S. mission to the moon in half a century. It could launch early in 2026.

On Monday, the space agency announced the 10 people chosen for its 2025 astronaut candidate class, selected from over 8,000 applicants across the U.S. That’s an acceptance rate of about 0.125%, making the odds far more daunting than Harvard’s 4% admission rate.

Ancient organisms may have left microscopic "biosignatures" on Mars. That's according to NASA scientists, who say a rock sample offers the most concrete proof yet that the red planet once hosted life.

Curiosity is exploring Mars’ boxwork terrain, where ridges and hollows may have formed from cementation and erosion. The rover has been documenting rock textures and chemistry, comparing smoother ridge rocks with nodular hollow-edge rocks.
