Ross generates electrical power using hand pedals to move crew and equipment translation aid (CETA) cart along a rail during underwater session in JSC's Weightless Environment Training Facility (WETF) Bldg 29. Wearing an extravehicular mobility unit (EMU), Ross operates CETA electrical cart as MS Jerome Apt holds onto the back of the cart. The two crewmembers are practicing a extravehicular activity (EVA) spacewalk they will perform in OV-104's payload bay during STS-37. CETA is a type of railroad hand cart planned as a spacewalker's transportation system along the truss of Space Station Freedom (SSF). SCUBA divers monitor astronauts' underwater activity.

S87-44061 (25 Sept 1987) --- Dr. Claude Nicollier, equipped with a pressurized extravehicular mobility unit (EMU), is in the process of being submerged in the 25-ft. deep pool of JSC's weightless environment training facility (WET-F) for a familiarization session. Dr. Nicollier's suit is weighted to facilitate a neutrally buoyant condition. He is assisted by two SCUBA-equipped divers. Dr. Nicollier, a Swiss scientist assigned to the STS-46 mission as a payload specialist, first came to the Johnson Space Center in July 1980. Along with Dr. Wubbo Ockels, another European Scientist, Dr. Nicollier underwent survival training and other basic astronaut-type training alongside the 1980 class of astronaut candidates. Some photos in this series show Dr. Nicollier in an extravehicular mobility unit (EMU). This is for familiarization purposes only as the scientist is not scheduled for any extravehicular activity.

KENNEDY SPACE CENTER, FLA. -- Technicians lower the unmanned robotic submersible recovery system, known as Max Rover, into the water at the Trident Pier at Port Canaveral during a test of the system. Kennedy Space Center's solid rocket booster (SRB) retrieval team and Advanced Systems Development laboratory staff hope that the new robotic technology will make the process of inserting the Diver Operated Plug (DOP) into the aft nozzle of a spent SRB safer and less strenuous. Currently, scuba divers manually insert the DOP into the aft nozzle of a jettisoned SRB 60 to 70 feet below the surface of the Atlantic Ocean. After the plug is installed, water is pumped out of the booster allowing it to float horizontally. It is then towed back to Hangar AF at Cape Canaveral Air Station. Deep Sea Systems of Falmouth, Mass., built the submersible for NASA

ISS010-E-07210 (16 November 2004) --- Salalah, Sultanate of Oman is featured in this image photographed by an Expedition 10 crewmember on the International Space Station (ISS). The city of Salalah is the capital of the Dhofar region of Oman and is known as the “perfume capital of Arabia”. The city is a popular destination for tourism due to the natural attractions of the al Qara Mountains (Jabal al Qara in Arabic) and abundant stands of frankincense trees lining mountain stream courses. These can be seen as green regions in the Jabal al Qara north of the city (located in the center of this image). The beaches and coastline are also major attractions for scuba diving and bird watching. Modern Oman is also represented by the Port of Salalah, located approximately 15 kilometers to the southwest of the city. The strategic location of this port has made it one of the major entry points to India, the Middle East, and Africa. The rectangular projection into the Arabian Sea visible in this photo is a large shipping container loading/unloading platform.
