From outside their underwater laboratory in Florida, NASA Astronaut and NEEMO 16 Commander Dottie Metcalf-Lindenburger and European Space Agency astronaut Timothy Peake took a call from NASA Administrator Charlie Bolden on June 18. Bolden was speaking from the NASA TV studio at the agency's headquarters in Washington, D.C.
An international crew of four headed by Lindenburger has been performing spacewalks on the ocean floor to test concepts for future asteroid exploration as part of the 16th NASA Extreme Environments Mission Operations (NEEMO) mission. While living underwater in the National Oceanic and Atmospheric Administration's Aquarius Underwater Laboratory off the coast of Key Largo, Fla., for 12 days, they're scheduled to perform a total of 16 underwater spacewalks. The mission is investigating communication delays, restraint and translation techniques and optimum crew size for an asteroid mission.
