This overall view shows STS-31 Mission Specialist (MS) Bruce McCandless II (left) and MS Kathryn D. Sullivan making a practice space walk in JSC's Weightless Environment Training Facility (WETF) Bldg 29 pool. McCandless works with a mockup of the remote manipulator system (RMS) end effector which is attached to a grapple fixture on the Hubble Space Telescope (HST) mockup. Sullivan manipulates HST hardware on the Support System Module (SSM) forward shell. SCUBA-equipped divers monitor the extravehicular mobility unit (EMU) suited crewmembers during this simulated extravehicular activity (EVA). No EVA is planned for the Hubble Space Telescope (HST) deployment, but the duo has trained for contingencies which might arise during the STS-31 mission aboard Discovery, Orbiter Vehicle (OV) 103.

STS-31 Mission Specialist (MS) Bruce McCandless II (left), wearing an extravehicular mobility unit (EMU), maneuvers his way around a mockup of the remote manipulator system (RMS) end effector during an underwater simulation in JSC's Weightless Environment Training Facility (WETF) Bldg 29 pool. The end effector is attached to a grapple fixture on the Hubble Space Telescope (HST) mockup. 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).

CAPE CANAVERAL, Fla. -- STS-124 Commander Mark Kelly sits in the cockpit of NASA's Shuttle Training Aircraft, or STA, preparing to practice space shuttle landings. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Because the orbiter is unpowered during re-entry and landing, its high-speed glide must be perfectly executed the first time. The crew for space shuttle Discovery's STS-124 mission is at Kennedy for a full launch dress rehearsal, known as the terminal countdown demonstration test, or TCDT. Providing astronauts and ground crews with an opportunity to participate in various simulated countdown activities, TCDT includes equipment familiarization and emergency training.

She and the rest of the crew are at KSC to take part in the Terminal Countdown Demonstration Test (TCDT) over the next three days. The TCDT is held at KSC prior to each Space Shuttle flight. It provides the crew of each mission an opportunity to participate in simulated countdown activities. The test ends with a mock launch countdown culminating in a simulated main engine cutoff. The crew also spends time undergoing emergency egress training exercises at the launch pad. This is Collins’ fourth space flight and second as commander.

KENNEDY SPACE CENTER, FLA. - STS-114 Pilot James Kelly suits up for practice flights on a Shuttle Training Aircraft (STA) used by Shuttle flight crews to practice landing the orbiter. The STA is a modified Grumman American Aviation-built Gulfstream II executive jet that was modified to simulate an orbiter’s cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter’s atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. The orbiter differs in at least one major aspect from conventional aircraft; it is unpowered during re-entry and landing so its high-speed glide must be perfectly executed the first time. There is no go-around capability. The orbiter touchdown speed is 213 to 226 miles per hour. There are two STAs, based in Houston. STS-114 is the first Return to Flight mission, scheduled to launch July 13 in a window that extends through July 31.
