Mars Science Laboratory Curiosity has been testing Martian dirt. There’s more to this than you’d think.
All the pictures are from NASA/JPL.
The first picture is a diagram of Curiosity. At the bottom left, the camera that is used to look at the ground is MAHLI (Molly).
Here are pictures of the dirt and surroundings of the samples.
This is the area on Mars called Rocknest.
This is the diagram showing the results of the soil tests. There is carbon, but they aren’t sure if it is from Earth or Mars. That will take time to figure out. It is carbon chlorine and it not organic. In other words, they have not found life on Mars. This is the last picture.
