PASADENA, Calif. (KABC) -- Two years ago, NASA's Curiosity rover touched down on Mars. On Tuesday, space lovers celebrated the milestone together at JPL in Pasadena.
Employees lined up on the steps for a group photo. They chanted "Dare Mighty Things" as the photo was taken.
"'Dare Mighty Things' is actually a motto for the laboratory. We want to be known for doing the things that nobody else can, pushing the edge," Project Manager Jim Erickson said.
They've done just that. In six months, they made what some consider the greatest discovery in mankind.
"If life ever existed on Mars, it could have survived," scientist Joy Crisp said.
"We found that we indeed have all that we need for habitability," Mars Program Manager Fuk Li said.
But so far, no Martians.
Curiosity's mission is still far from over. It continues to inspect ancient habitable environments and major changes in Martian environmental conditions.
Meanwhile back on Earth, the scientists say they're ready to make another historic discovery.
The sky's the limit, or rather there is no limit as they "Dare Mighty Things."
