S92-49812 (11 Nov 1992) --- Astronauts Gregory J. Harbaugh and Susan J. Helms, mission specialists assigned to fly aboard the Space Shuttle Endeavour for the STS-54 mission, rehearse for the upcoming flight. The two are in the airlock of a trainer at the Johnson Space Center's crew systems laboratory. Harbaugh and Mario Runco Jr., also a mission specialist, have been assigned to perform a four-hour-plus extravehicular activity (EVA). Helms is to assist the pair of spacewalkers during the mission as well as in this training exercise.

S92-40569 (Aug 1992) --- Gregory J. Harbaugh, one of five astronaut crewmembers assigned to fly aboard the Space Shuttle Endeavour for the STS-54 mission, pauses for a break during training and preparations for the six-day mission. Harbaugh will be joined by John H. Casper, mission Donald R. McMonagle, pilot; along with Mario Runco Jr. and Susan J. Helms, mission specialists. Harbaugh is in the weightless environment training facility (WET-F) at the Johnson Space Center (JSC).

1990 Group 13 Astronaut Candidates (ASCANs) Susan J. Helms (foreground) and William G. Gregory, wearing helmets and flight suits, swim in pool at Elgin Air Force Base (AFB) in Pensacola, Florida, during water survival exercises. The training familiarized the candidates with survival techniques necessary in the event of a water landing. ASCANs participated in the exercises from 08-14-90 through 08-17-90.

Runco and Harbaugh discuss the trunnion / payload retention latch assembly (PRLA) configuration.

S92-42753 (31 July 1992) --- Astronaut Susan J. Helms, mission specialist assigned to fly aboard the Space Shuttle Endeavour for the STS-54 mission, gets assistance to complete the donning of her spacesuit. Though not assigned to the scheduled extravehicular activity (EVA), Helms is trained in the weightless environment training facility (WET-F). She will aid astronauts Gregory J. Harbaugh and Mario Runco Jr. in their planned EVA, scheduled for January of next year, and serve a backup role. Wearing this high fidelity training version of the extravehicular mobility unit (EMU), Helms was later lowered into the 25-ft. deep WET-F pool. The pressurized suit is weighted so as to allow Helms to achieve neutral buoyancy and simulate the various chores of the spacewalk.

S92-42754 (31 July 1992) --- Astronaut Susan J. Helms, mission specialist assigned to fly aboard the Space Shuttle Endeavour for the STS-54 mission, gets assistance to complete the donning of her spacesuit. Though not assigned to the scheduled extravehicular activity (EVA), Helms is trained in the weightless environment training facility (WET-F). She will aid astronauts Gregory J. Harbaugh and Mario Runco Jr. in their planned EVA, scheduled for January of next year, and serve a backup role. Wearing this high fidelity training version of the extravehicular mobility unit (EMU), Helms was later lowered into the 25-ft. deep WET-F pool. The pressurized suit is weighted so as to allow Helms to achieve neutral buoyancy and simulate the various chores of the spacewalk.

S92-42755 (31 July 1992) --- Astronaut Susan J. Helms, mission specialist assigned to fly aboard the Space Shuttle Endeavour for the STS-54 mission, completes the donning of her spacesuit before a training exercise. Though not assigned to the scheduled extravehicular activity (EVA), Helms is trained in the weightless environment training facility (WET-F). She will aid astronauts Gregory J. Harbaugh and Mario Runco Jr. in their planned EVA, scheduled for January of next year, and serve a backup role.

The pressurized suit is weighted so as to allow Helms to achieve neutral buoyancy and simulate the various chores of the spacewalk.

S92-45750 (1 Sept 1992) --- Astronaut John H. Casper, mission commander, assigned to fly aboard the Space Shuttle Endeavour for the STS-54 mission, gets in some rehearsal time at JSC's Shuttle mockup and integration facility. Part of a spacesuit is visible at lower right. Two STS-54 crewmembers will spend four-plus hours wearing extravehicular mobility units (EMU) for a planned spacewalk in a continuing evaluation program for EVA techniques and gear for Space Station Freedom.

S92-45751 (1 Sept 1992) --- Astronaut Mario Runco Jr., mission specialist assigned to fly aboard the Space Shuttle Endeavour for the STS-54 mission, gets in some rehearsal time with a camcorder. He is on the middeck of a Shuttle trainer.

Helms, wearing helmet with oxygen mask and inflated life jacket, is assisted by training instructor during water survival exercises at Elgin Air Force Base (AFB) in Pensacola, Florida. Helms looks on as the instructor adjusts her parachute harness. When ready, Helms will be dropped from the harness into the pool (in background) to simulate a water landing after T-38 ejection. ASCANs participated in the exercises from 08-14-90 through 08-17-90.

S93-25030 (15 Dec 1992) --- Two astronauts assigned to fly aboard Endeavour for the STS-54 mission are briefed on the slidewire escape system at the launch pad. Pictured in the slidewire litter are astronauts Gregory J. Harbaugh (left) and Susan J. Helms, mission specialists. They are assisted by Max Kandler of Lockheed, Houston. All five crewmembers are in Florida this week to participate in countdown demonstration tests.
