r/Mars

The objective of this observation is to determine the nature of a group of mounds, some of which have small pits at their summits. These features may be caused by ground ice melting and possibly turning into steam. They are barely visible in Context Camera image, so our camera’s resolution can help us to determine how they were formed.

Full description for the right image

​An overview looking down on a section of the rock surface has an unsorted sharp-aggregate-in-rough-cement texture. In the centre is a protruding inclusion, no more than a chip of stone, that stands out for its white grey dappled appearance.​

Did Perseverance find evidence of past life on Mars last year? 🦠

The rover discovered very specific minerals on the rim of a Martian crater. On Earth, those minerals are biosignatures, or evidence of life. We can't say for sure it's a Mars biosignature, because non-biological processes can make these minerals too. However, those processes leave other evidence in the rocks that we're not seeing. That means our best explanation right now is past Martian biology.
