NASAs Curiosity Rover has discovered yellow and pure sulfur crystals on Mars.
There are many rocks containing sulfate a type of salt made from chemicals but this is the first time someone has come across yellow colored pure sulfur crystals.
NASA’s Curiosity Rover has been exploring the foothills of Mount Sharp on Mars for nearly a decade. Recently, the rover discovered a field of rocks made of pure sulfur, a first for the mission. A rock Curiosity drove over cracked open to reveal yellow sulfur crystals. The rover has been exploring a region of Mars rich in sulphates, a type of sulfur-based salt formed by water evaporation.
Curiosity's mission is to study whether Mars' terrain may have supported microbial life in the past. Scientists are particularly interested in the Gediz Vallis channel, as it provides insights into the planet's history. The rover's ascent up Mount Sharp has provided clues about ancient floodwaters and landslides, which have contributed to the landscape.
A significant discovery was a large sulfur rock called 'Mammoth Lakes'. Scientists identified a safe spot on the sloping surface of the rock to proceed with drilling.
