  • Mars may once have had an ocean--but only for a geological eye blink. This puts a dampener on ideas that there is or was life on the Red Planet. That's according to a theory from Tim Parker of NASA's Jet Propulsion Laboratory in Pasadena CA. Speaking at the Lunar and Planetary Science Conference in The Woodlands, Texas, in March, he argued that a sustained barrage of asteroids hitting the young Mars could have delivered short-lived water to the surface.
