In this interview, Jeff Moersch describes the DAN instrument on the Mars Curiosity rover. Donated by the Russian Federal Space Agency, this instrument will search for underground water without any need for digging.

Jeff Moersch, at the University of Tennessee-Knoxville, is one of the American scientists working on DAN. Astrobiology Magazine spoke with Moersch at the start of his Mars day, at 2 pm local time, when he was just waking up.
