   Nov 28, 2023 · Astrobiology is the study of the origin, evolution, and distribution of life in the Universe, and searching for life on Mars is a major goal of the Mars 2020 mission. While humans have long wondered whether there are others like us, it’s only been a few decades since we’ve developed the technologies to search for life beyond Earth in earnest.

   Does Mars have a climate like 3 billion years ago?

   • “Discerning the climate of Mars approximately three billion years ago is challenging because the Martian surface features do not seem to fully support either a warm and wet or cold and dry climate during that time,” said Michael Way, co-lead author of the paper at NASA’s Goddard Institute for Space Studies, New York.

   He’s been working at the National Air and Space Museum’s Center for Earth and Planetary Studies for 23 years, and he’s been hunting for ancient life on Mars even longer than that. Probes in orbit around the planet and rovers on the surface take images of the Martian landscape, and John searches the areas in and around ancient waterbeds for signs of places that once may have been habitable.
