1. • • NASA scientists hunting for life beyond Earth form a broad coalition: those investigating our solar system, ancient or extreme life forms on Earth, and even our Sun. Signs of life might be found on Mars, Jupiter's moon Europa or Saturn's moon Enceladus, and potential future missions are in the conceptual or planning stages.

   Is Mars habitable?

   • The question is, “Is it habitable and for whom?” Mars is hundreds of degrees colder than Earth; it has a hundred times less atmosphere and that atmosphere has hardly any oxygen. But there may be other forms of life that could have evolved that aren’t very much like us but are very much like the early forms of life that evolved on Earth.

   Nov 28, 2023 · Finding extraterrestrial life is a central aspect of astrobiology, but finding no life on a once-habitably rocky planet like Mars would be equally important, because it would help us look back into our own origins to query what makes Earth biologically unique, and would also help us prepare to search for life elsewhere.
