NEEMO, which stands for NASA Extreme Environment Mission Operations, is one facet of NASA's Analog and Field Testing Missions. As NASA plans to expand human spaceflight and robotic exploration beyond low Earth orbit, astronauts are being trained to meet these challenges. Future destinations may include the moon, near Earth asteroids and Mars and its moons.
To prepare for the challenge of exploring these destinations in space, NASA conducts missions here on Earth, in remote locations that have physical similarities to extreme space environments.
