Hints: Antarctic Mars NASA authorisation

We have some data, but we are not sure 100%. But probably we have now isolated bacteria from Antarctic permafrost. It's between eight and 15 million years old.

If life can survive in Antarctica for 15 million years, then something could be waiting to be revived on Mars. These discoveries put new urgency in the quest to find water on Mars. There was now a real possibility that they might find something alive. So authorisation came from the very top: send more missions to Mars. NASA launched several probes with the express purpose of mapping the composition of the Martian surface.
