Scientists were stunned on May 30 when a rock that NASA's Curiosity Mars rover drove over cracked open to reveal something never seen before on the Red Planet: yellow sulfur crystals.

New satellite images reveal spider-like formations on the dusty soil of Mars. What are these?

A new theory suggests that NASA's Curiosity rover could be "burping" the surface of the Red Planet, releasing methane trapped beneath a salty crust.

NASA's Curiosity rover continues its quest to find signs of microbial life on Mars.

NASA's Curiosity rover has discovered the first evidence that Mars once had a climate which alternated between wet and dry seasons similar to Earth, a study said on Wednesday, suggesting the red planet may have once had the right conditions to support life.

Researchers believe waves on a tiny lake billions of years ago created these patterns.

Yellow crystals of elemental sulfur were revealed after NASA's Curiosity rover happened to drive over a rock and crack it open on May 30, 2024, according to the Curiosity team.

NASA's Curiosity rover, which is currently exploring Mars's Gale Crater, recently marked an impressive milestone: 4,000 days on Mars.

Four thousand Martian days after setting its wheels in Gale Crater on Aug. 5, 2012, NASA's Curiosity rover remains busy conducting exciting science. The rover recently drilled its 39th sample, then dropped the pulverized rock into its belly for detailed analysis.

NASA's Curiosity rover found peculiar polygonal shapes that suggests Mars' ancient environment could have sprouted life's building blocks.

This is some of the best confirmation yet that the NASA robot is exploring a former lakebed.

It's the clearest evidence of waves and water the Curiosity rover has ever found.

NASA's Curiosity rover has found wave-rippled rocks -- evidence of an ancient lake -- in an area of the planet expected to be drier, the US space agency said Wednesday.

Craggy sandstone is stopping the rover's ascent of a Martian mountain.

The rover Curiosity found sulfur crystals in a Martian rock for the first time. Researchers say they shouldn't be there and are seeking an explanation. The post Martian rock crushed by Curiosity hides a surprise! first appeared on EarthSky.

While surveying the site of an ancient channel on Mars, the Curiosity rover ran over a rock and discovered pure sulfur on the red planet for the first time.

Could this mean that there's sign of life in Mars?

"I can't imagine what it would have been like to witness these events."

This spot on Mars has preserved information about ancient landslides and evidence of Red Planet water.
