Part 4/6:
The speaker elaborated on a statement made during the live stream that suggested Mars is no longer capable of supporting liquid water or life on its surface. This assertion stands in stark contrast to information on NASA's official site, which claims there have been observations of liquid water on Mars in the past. The presenter criticized the mixed messages coming from NASA, citing their own publications, notably their book dedicated to exploring water on Mars, suggesting that there may be ongoing misinformation or a lack of awareness among NASA's representatives.
