Data from an old NASA spacecraft reveals a volcano erupted on the surface of Venus in 1991, a new study in Science says.
NASA engineer Nagin Cox lives on Earth but works on Mars time, where days are longer and time works differently. Her work with the rovers has entirely changed the way she thinks about time on Earth.
Since touching down in Jezero Crater, NASA's Perseverance rover has already cached 6 samples that could one day be brought back to Earth. Astrobiologists hope they hold signs of past microbial life.
Another six-wheeled rover is about to land on Mars. NASA Perseverance's mission is headed to Jezero Crater, which once may have been a lake. It's carrying two new items: a microphone and a helicopter.
China's space agency, fresh off a successful sample-return mission to the moon, says the ambitious Tianwen-1 rover mission it launched in July had reached the Red Planet.
NASA's admission this week that the agency has lost contact with a Mars rover brings an end to a compelling story of usefulness and resilience.
Space scientists on Earth have improvised a tool on the Mars rover to help them figure out how a giant mountain on the Red Planet came to be. Their surprising conclusion: It's likely windswept sand.
As the dust storm grows and the solar-paneled Opportunity remains asleep, the younger Curiosity rover has been able to power through.
