InSight began digging at the end of February and the team admitted to having problems early March. Now researchers would collect data and decide whether to continue drilling or consider withdrawing to try again.
"We can probably start trying to re-enter in a few weeks," said Spohn, according to News from the space. "Before that, we want to make sure we do the right things."
