Mars continues to surprise us. While digging this weekend the mole backed about halfway out of the ground. Preliminary assessment points to unexpected soil properties as the main reason. Team looking at next steps. #SaveTheMole #Teamworkpic.twitter.com/UURvU8VTwZ

One possibility observed in testing on Earth is that soil could fall in front of the mole’s tip as it rebounds, gradually filling the hole in front of it as the mole backs out. Team continues to look over the data and will have a plan in the next few days

Subsurface soil not containing expected moisture levels? I think of sand when I see substrate filling in gaps like that. Very intriguing, keep learning!

Moisture content is no different than what we expected before we landed: it’s very dry.
