Goddard Space Flight Centre Divers (2008)

In planning for Servicing Mission 4 to Hubble crew members divide their time between NASAs Johnson Space Centre Houston working underwater on a Hubble mockup to simulate the effects of weightlessness and NASAs Goddard Space Flight Centre Greenbelt Maryland where they practice scheduled mission tasks on a Hubble mockup inside a large clean room facility Many Goddard engineers are trained divers These engineers work along side the astronauts while in the Neutral Buoyancy Lab to aid in their training This underwater experience helps HST engineers understand what the astronauts need as they work together to refine tools and procedures to service Hubble
