Astronauts train at Maxwell
Peggy Whitson, training lead for astronaut expeditionary skills at the NASA Johnson Space Center in Houston, and Maj. Jeremy Hansen, Royal Canadian air force astronaut, assemble a tent at the vigilant warrior training range near Maxwell Air Force Base, March 4th. The training provided a survival scenario where the group of six astronauts had to build shelter and survive the night while dealing with exercise inputs from the Academy of Military sciences administrators.
