1dNASA was flummoxed last week when the Perseverance rover attempted to collect its first rock core sample only to find the sample tube empty. The missing core was nowhere to be found, so the team had to take a step back and assess the situation on Mars. Now, NASA believes it has worked out what happened , and it’s ready to set course for the next sampling location. The Perseverance rover has a sui
