The recent discovery of liquid water on Mars and the flight of a NASA helicopter suggest that the Martian atmosphere is much thicker than the 0.6% NASA officially claims. Mike Adams argues that basic physics would prevent a helicopter from flying or liquid water from existing at such low pressures. He alleges that NASA has buried evidence of microbial life on Mars since the 1976 Viking lander to maintain an "artificial history" of the planet.
