Mission Aquarius: Neemo16
The ocean floor is the best place on earth to train for space. NASA Extreme Environment Mission Operations (NEEMO) and has sent 16 missions to Aquarius since 2001, and led to invaluable astronaut learning and training. Being weightless and saturated changes the mind set. The aquanauts know they can't surface -- they might as well be on the moon. The June 2012 mission shown here focused on exploring asteroids, and may be the last NASA trip to the underwater space base.
