Finding Neemo: Nasa goes from the bottom of the ocean to outer space | Andrea Boyd
Nasa astronauts-aquanauts have made a temporary underwater home to prepare for future missions. An Aussie space engineer is part of the team
On Sunday a group of six astronauts, engineers and scientists submerged 19 metres to the bottom of an Atlantic Ocean reef to live underwater for Nasa’s extreme environment mission operations (Neemo) expedition.
