Life on Mars: time to start

All the data we have gathered after a lot of NASA missions are consistent with life. The reader remembers the Labeled Release (LR) experiment on NASA’s Viking missions, 1976: it satisfied the pre-mission criteria for the detection of microbial life on Mars [1]. Soon after, the claim that extant life was found was disputed by several alternative hypotheses. This resistance focused primarily on the (supposed) absence of liquid water on the surface of Mars (being the Martian atmospheric below the triple point pressure of water, 610 Pa, water can exists there only as a solid or vapor), and on the failure of the Viking chromatograph-mass spectrometer (GC-MS) to find any organic matter. To this day, the picture has been changed.
