NASA’s Curiosity rover made a groundbreaking discovery by accidentally crushing a rock and revealing pure sulphur in the Gediz Vallis channel on Mars. This channel, shaped by ancient rivers, is rich in sulphates, drawing scientific interest. The finding of pure sulphur crystals is surprising since sulphur typically forms under specific conditions, prompting questions about Mars’ geological history. NASA’s team is now studying how ancient floodwaters and landslides might have contributed to the channel’s formation. Curiosity’s latest drill sample from a nearby rock will further help in analyzing these mysterious sulphur deposits.
