Mars

Evidence continues to build that volcanic activity on Mars didn't die out long ago.

The detection of a toxin that makes humans and pigs vomit could solve the lingering 100-year-old mystery surrounding the pristine Martian meteorite nicknamed "Lafayette."

Steve Squyres, the principal investigator of the Opportunity mission, could have switched to Saturn. But learning about water on Mars kept him going on one mission for 30 years.

Experiments have shown how the world's hardiest microbe could endure freezing, dry and irradiated conditions on Mars.

The science goals set for Europe's beleaguered ExoMars rover are still unique, European Space Agency said, as it laid down plans to ask member states to fund a new homegrown descent module.

Perseverance has socked away 14 drilled-out Mars rock cores to date — two apiece from seven target rocks — and it will likely drop half of them in a "depot" in November or December.

After a treacherous journey, NASA's Curiosity Mars rover has reached an area that is thought to have formed billions of years ago when the Red Planet's water disappeared.

Join a crowd of Red Planet researchers at the 2022 International Mars Society Convention, which is broadcasting some of the activities online.

The Mars Express spacecraft has witnessed a rare spectacle, spotting Mars' moon Deimos appearing to pass in front of Jupiter and its moons on Valentine's Day (Feb. 14).

Director Ryan White shares his thoughts on his new documentary, "Good Night Oppy," the real-life fable of a Mars robot that refused to die and the dedicated NASA team that kept it going.

NASA engineers are firing micro-bullets at squares of anti-meteoroid shield material that will protect a Mars sample return orbiter during its journey back to Earth.

Touching safely down on Mars is a true, nail biting event. Landing securely on Mars remains a delicate balance of technical skill, mixed in with hard-earned luck.

During the late evening hours of Friday (Oct. 14), Mars will rendezvous with the moon in the night sky.

NASA's Perseverance rover recently grabbed its 14th Red Planet rock sample but is having trouble sealing it up for eventual shipment to Earth.

Your opportunity has arrived to take a first look at a new film about a groundbreaking journey on Mars. Amblin Entertainment and Amazon Studios have debuted the trailer for "Good Night Oppy."

Ancient microbes triggered a climate change on Mars that made the planet less habitable, which may have ultimately led to their extinction, a new climate modeling study suggests.

Scientists have acknowledged for months that the mission's end was near, and now, a continent-size dust storm is darkening the Martian skies, further impacting power production.

In new research, we used data from InSight to detect and locate four high-speed meteoroid collisions, and then tracked down the resulting craters.

Scientists revisiting a puzzling signal from the south pole of Mars have suggested a new potential explanation, and it doesn't bode well for hopes of finding liquid water on the Red Planet.

Mars may be a freeze-dried planet now, but once, it was supposedly (almost) another Earth, with flowing water that froze into hulking mountains of ice.
