Overview

• The Curiosity rover accidentally uncovered sulfur crystals while driving over rocks in the Gediz Vallis channel.
• This is the first time elemental sulfur has been found on Mars, as previously only sulfur-containing minerals were observed.
• The discovery challenges current scientific understanding of the Martian environment and its history.
• Scientists are now investigating how these crystals formed under the planet's conditions.
• The rover's Alpha Particle X-Ray Spectrometer confirmed the composition of the sulfur crystals.
