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