NASA collaborators recently admitted that aren't sure what's wrong with the InSight lander's instrument that was supposed to get into the surface of Mars and measure the heat flow of the planet's interior. "At about 30 centimeters depth we encountered something," said Germany space agency researcher Tilman Spohn at a recent conference, according to Space News . “We don't know yet if it's a harder layer of regolith or rock.”
InSight started digging in late February, and the team admitted it had trouble in early March. Now, researchers are reportedly gathering data and deciding whether to keep drilling or consider pulling out to try again.
"Spohn said, according to Space News . "Before that, we want to make sure we're doing the right things."
