“Early Mars was an extremely active planet from a geological point of view,” said Alberto G. Fairén, a visiting astrobiologist at Cornell University. “The planet had the conditions needed to support the presence of liquid water on the surface – and on Earth, where there’s water, there’s life. “So early Mars was a habitable planet,” he said. “Was it inhabited? That’s a question that the next rover Perseverance will help to answer.”
“It’s worthwhile to not just do what was done 60 years ago, but also to keep an eye out for very unusual things,” says SETI Institute astronomer Seth Shostak. “The universe has been around for three times as long as the Earth has been around, so there could be aliens out there that are very, very much more advanced than we are—not just 1,000 years, but millions and billions of years ahead.”

“One can best feel in dealing with living things how primitive physics still is,” said Albert Einstein. “Can life be explained in terms of physics or will it always be a mystery? And if physics can explain life, is existing physics up to the job, or might it require something fundamentally new – new concepts, new laws even?” asks Arizona State University cosmologist, theoretical physicist, and astrobiologist, Paul Davies answering Einstein.
