NASA will hold a press conference Tuesday to announce "significant findings" about water on Mars based on evidence from its Opportunity Mars rover.
"It's going to be the most significant science results that we've had from the rovers, and it's bearing on their primary mission," NASA spokesperson Don Savage told SPACE.com . That mission is to find signs of water that might support life.
Will the announcement change how we think about Mars?
"Anything of a significant nature has that possibility," Savage said. "Sure."
If there is liquid water presently at the surface of Mars, as several lines of rover evidence have hinted, then most scientists agree there is the possibility that life could exist. Water does not mean life, but it is the key ingredient that makes life possible.
