Mars crater hints at recent water activity on Mars
European researchers report in Nature Communications that the Istok crater shows signs of water laden debris flows within the last million years. HiRISE data and Earth analogs suggest debris with 20 to 60 percent water carved gullies, implying a much wetter mid latitude Martian past aided by orbital tilt shifts increasing the planet's water cycle and potential for microbial life.
