Three STS-114 astronauts give a thumbs-up sign to indicate preparedness during an underwater training session in the Neutral Buoyancy Laboratory in Houston. From left, they are Soichi Noguchi, Stephen K. Robinson and Andrew S.W. Thomas. A number of SCUBA-equipped divers participated in the dive to assist the astronauts. Noguchi and Robinson have been in training for a lengthy period of time, preparing for three scheduled space walks.
