Mars

NASA astrobiologist Heather Graham answers pressing questions about life on Mars.

An astrophotographer has captured a highly detailed image of the Red Planet reappearing from behind the moon after a lunar occultation.

'My team's not worried' about dust or wind disturbing the lightsaber-shaped cache tubes, NASA's Perseverance mission wrote on Twitter.

NASA celebrated the new year on Mars, which happens on Dec. 26 — days before the Gregorian calendar changes over to 2023 on Earth.

NASA's Mars Insight lander died a slow death by dust. Could anything have been done to save it?

We know very little about Mars rock glaciers, but scientists do suspect that they may hold significant amounts of water.

NASA is making the case for a "winter wonderland" on Mars in a new video from the Jet Propulsion Laboratory in California.

A newly released image of Mars shows an icy scene, with ribbons of red and white dancing across a frosty landscape near the planet's south pole.

NASA's Artemis 1 Orion spacecraft made an epic flight to the moon, Russia invaded Ukraine and SpaceX set a few records.

NASA's Perseverance rover successfully dropped its second rock sample tube on the Martian surface, its longest sample yet.

The design of the sample return tubes carried by NASA's Perseverance rover looks suspiciously like a 'Star Wars' lightsaber, inspiring one NASA director to joke about using the Force on Mars.

There may have been no oxygen in the atmosphere of ancient Mars after all, a new study has found, but don't despair, there still could have been living creatures crawling on the planet.

Even though winds on Mars are weak, they could be sufficient to provide power for future exploration and colonization of the Red Planet, a new study finds.

NASA's Perseverance rover collected this tube's sample from a Mars region rich in organics. Scientists soon will scrutinize tubes like this for signatures of life.

NASA's Ingenuity Mars helicopter flew for the 37th time on Saturday (Dec. 17), acing a hop designed in part to test the capabilities of its new software.

The Red Planet's harsh dust has claimed another spacecraft.

NASA lost contact with its Mars InSight lander on Monday (Dec. 18) after the spacecraft failed to respond to communications from its control team.

This photo from NASA's InSight lander on Mars just may be its last as the power-starved lander approaches the end of its life on the Red Planet.

A Marsquake detected by NASA's InSight lander in May this year was at least five times larger than the next largest seismic event recorded on the planet.

NASA's Perseverance rover is set to cache its first Mars sample in the next few days, kicking off a roughly month-long process that will see the robot drop 10 tubes of Red Planet material.
