All Things Space, UFOs, etc.New research shows Mars’ Jezero crater was repeatedly habitable Posted on October 27, 2025 by Administrator Earlier this month, NASA provided an update on the possible discovery of a biosignature by the Perseverance rover in Jezero crater. Now, another team of scientists has said the crater – which used to be a lake billions of years ago – experienced multiple periods of habitability. Water was more abundant during those periods of time. Eleanor Moreland at Rice University in Houston, Texas, led the new study. The researchers said on September 17, 2025, that Perseverance found two dozen types of minerals showing water altered volcanic rocks in the region. The evidence reveals three distinct periods of habitability. They shifted from least (but still potentially) habitable to the most habitable over time.
