Scientists have long searched for evidence that there might have once been life on Mars. The recent discovery of mud cracks on the planet has led to interest from the scientific community, as well as speculation that it could be a sign that life once existed on the Red Planet.
NASA’s Curiosity Mars rover recently captured a closer look at a series of slabs of rock that has unexplained markings. Experts believe the markings are likely mud cracks, indicating that bodies of water may once have existed on the planet. The markings could be a sign that the water covering the rocks eventually dried up, leading to cracks in the dirt on their surface.
The cracks are consistent with other evidence NASA has found in an area called Mount Sharp, which is a mountain on the planet. The Rover has been exploring in this area for months. One scientist on the project noted that the Rover is uncovering more evidence that there were multiple lakes that varied in depth and size and over time, they occasionally disappeared.
Additionally, scientists have discovered rocks with evidence of something known as cross bedding. This could indicate areas where water flowed rapidly, like shorelines.
