Evidence of melting snow on Mars flowing into gullies hints at prospect of life on planet

Daily Mail  

NASA's Perseverance Mars rover is about to start a search for signs of ancient Martian life, but new research hints at the prospect of current life on the Red Planet. Within those images study authors Aditya Khuller and Philip Christensen found the lowest latitude evidence of dusty water ice on Mars that has formed into gullies. The melting of this dusty water ice could provide places for any surviving life to exist on Mars. Mantles found in the Dao Valles on Mars show a gully incision possibly made by dusty melting water ice exposed to the warmer equatorial summer weather This is due to the fact small amounts of liquid water may be produced within these water ice deposits in the summer - at the equator. 'We believe that these dusty ice deposits are the best candidates to look for small amounts of shallow liquid water, and therefore potentially ideal locations for any surviving life on Mars.'
