It has grass and some dirt that were all frozen for the first week but luckily what we did, or not so luckily, is we brought the rain with us. We brought the warm weather with us and we got a lot of mud. We don't expect to see a lot of mud on Mars. |
We wanted to get these drills out of the lab environment and test them in the harsh conditions of the field. |
