But whether that water was surface water in a lake or river, or groundwater, remains uncertain, Farley added. Either could constitute an ancient , habitable Martian environment, he said. What's possible is that microbial life could have lived in Jezero during one or more of those wet periods. If true, evidence of leftovers from those little critters might be discovered in lakebed or shoreline sediments. As for the overall health of the Perseverance rover, Farley noted a couple of issues: For one, loss of wind sensors that are part of the Mars Environmental Dynamics Analyzer , built by an international team led by Spain's Centro de Astrobiología.
Earlier in its trekking of Mars, Perseverance dropped 10 sealed sample tubes at a depot location dubbed"Three Forks" in Jezero Crater. The intent is that a Mars Sample Return mission in the future would pick up sample tubes for rocketing those bits and pieces of Mars to Earth.
