Methane on Mars | NASA Planetary Sciences
Explore whether Mars is alive -- geologically or biologically -- in this video from NASA. Satellite images and the recent discovery of water ice on the surface of Mars suggest liquid water is flowing beneath the surface, which could make it a habitable planet. The controversial discovery of methane plumes, which could be produced from a geological or biological source, could help scientists determine whether life is present. The video looks at the scientific research being conducted to test hypotheses, explores the similarities between Mars and Earth, and introduces how future missions to Mars could help scientists learn more.
