Ian Tonglet, 13, (left) and Seth Malley, 13, both of Picayune, Miss., and both participants in the 2010 Astro Stars session at Stennis Space Center, work with an underwater robot during a camp activity June 29. NASA joined with the U.S. Navy for the underwater robotics exercise involving Sea Perch robots, which are simple, remotely operated underwater vehicles made from PVC pipe and other inexpensive, easily available materials. During the Stennis exercise, students used robots constructed earlier in the day to maneuver underwater and collect plastic rings, as seen to the left of Tonglet. Astro STARS (Spaceflight, Technology, Astronomy & Robotics @ Stennis) is a science and technology camp for 13-15 year olds.

Two EcoMapper AUVs (autonomous underwater vehicles) are seen onboard the the Woods Hole Oceanographic Institution research vessel Knorr on Tuesday, Sept. 4, 2012, in Woods Hole, Mass. The EcoMappers will be deployed in the Atlantic Ocean as part of the Salinity Processes in the Upper Ocean Regional Study (SPURS) which is set to sail on Sept. 6. The NASA-sponsored expedition will sail to the North Atlantic's saltiest spot to get a detailed, 3-D picture of how salt content fluctuates in the ocean's upper layers and how these variations are related to shifts in rainfall patterns around the planet.

As McCandless performs contingency extravehicular activity (EVA) procedures, fellow crewmember MS Kathryn D. Sullivan, in EMU, works on the opposite side of the HST mockup, and SCUBA-equipped divers monitor the activity. Though no EVA is planned for STS-31, the two crewmembers train for contingencies that would necessitate leaving the shirt sleeve environment of Discovery's, Orbiter Vehicle (OV) 103's, crew cabin and performing chores with the HST payload or related hardware in the payload bay (PLB).

KENNEDY SPACE CENTER, FLA. - A view from inside the pilot house of the Liberty Star overlooks the stern where a team secures lines to underwater research equipment being used on an expedition to characterize the condition of the deep-sea coral reefs and reef fish populations in the Oculina Banks. The banks are a marine protected area, 20 miles offshore of the east coast of Florida. The equipment includes an underwater robot, a seafloor sampler, and the Passive Acoustic Monitoring System (PAMS), originally developed by NASA to monitor the impact of rocket launches on wildlife refuge lagoons at KSC.

A team of scientists will deploy an underwater robot, a seafloor sampler, and the Passive Acoustic Monitoring System (PAMS), originally developed by NASA to monitor the impact of rocket launches on wildlife refuge lagoons at KSC. The research is sponsored by NOAA Fisheries. The ship departed from Port Canaveral April 29 and will return May 9.
KENNEDY SPACE CENTER, FLA. - Underwater research equipment is prepared for immersion from the Liberty Star, the NASA Space Shuttle support ship operated by United Space Alliance. It is being used on an undersea expedition to characterize the condition of the deep-sea coral reefs and reef fish populations in the Oculina Banks, a marine protected area, 20 miles offshore of the east coast of Florida. The equipment includes an underwater robot, a seafloor sampler, and the Passive Acoustic Monitoring System (PAMS), originally developed by NASA to monitor the impact of rocket launches on wildlife refuge lagoons at KSC.

KENNEDY SPACE CENTER, FLA. - Underwater research equipment slowly sinks into the water. An undersea expedition is underway to characterize the condition of the deep-sea coral reefs and reef fish populations in the Oculina Banks, a marine protected area, 20 miles offshore of the east coast of Florida. The equipment includes an underwater robot, a seafloor sampler, and the Passive Acoustic Monitoring System (PAMS), originally developed by NASA to monitor the impact of rocket launches on wildlife refuge lagoons at KSC. The research is sponsored by NOAA Fisheries and will take place onboard the Liberty Star. The ship departed from Port Canaveral April 29 and will return May 9.
