An anonymous reader shares a report: A blue-ribbon panel of researchers chaired by the University of Toronto’s Barbara Sherwood Lollar assembled the report at the behest of the US Congress, which asked in a 2017 law that a “strategy for astrobiology” be developed to prioritize “the search for life’s origin, evolution, distribution, and future in the universe.” The 196-page report does not offer easy access to ET, but the steady drumbeat of scientific advancement it documents suggests an increasingly sophisticated understanding of what we know — and don’t know — about biology on our planet and beyond. Indeed, the recently gained knowledge it highlights is the front end of a wave: Only the Viking mission in the 1970s hunted rigorously for signs of life on other planets, and now the first new NASA mission to do so, the Europa lander, is being designed. In the past four years alone, scientists using data gathered by space probes on Mars discovered evidence of past surface water, the presence of nutrients and organic molecules, and methane gas in the atmosphere that varies by season. This doesn’t mean life exists now on Mars, but it is helping contribute to an understanding of astrobiology as a discipline that looks at physical and chemical processes over time to determine if the conditions for life once existed or may do so in the future.
