Aquanauts on an Asteroid Mission
Topic: Meteorites, Comets and Asteroids
07/21/12
A team of aquanauts were recently joined by ESA astronaut Tim Peake to test communication strategies for a future mission to an asteroid. The explorers spent 12 days underwater on the Neemo mission simulating a trip to an asteroid 15 million kilometers from Earth.

Design for a Deep Space Habitat
Topic: Meteorites, Comets and Asteroids
