Astronaut Norman E. Thagard, mission specialist for the "silver" team, rests on the middeck while the "gold" team is on duty in the science module. Don L. Lind, left, "gold" team member, meanwhile participates in autogenic feedback training (AFT), designed to help flight crewmembers overcome the effects of zero-gravity adaptation.

51D-06-015 (12-19 April 1985) --- Astronaut Jeffrey A. Hoffman and Rhea Seddon mission specialists, demonstrate the effect of weightlessness on a slinky toy in the mid-deck of the Space Shuttle Discovery.

STS60-29-009 (10 Feb 1994) --- On the Space Shuttle Discovery's aft flight deck, Russian cosmonaut Sergei K. Krikalev prepares for one chore while performing another. Using the Shuttle Amateur Radio Experiment (SAREX) gear, the mission specialist was talking with students in Maine. He holds a camcorder, which was later called into action to record inflight activities. Krikalev joined five NASA astronauts for eight days in space aboard Discovery.

STS031-04-002 (24-29 April 1990) --- Astronauts Kathryn D. Sullivan and Bruce McCandless II, mission specialists, work together to perform one of the mission's medical experiments. The experiment is Detailed Supplementary Objective (DSO) 462, Non invasive Estimation of Central Venous Pressure During Spaceflight. Sullivan applies a gel substance to a transducer which will be placed on McCandless' jugular vein to collect the sought data. The cable links to a data recorder.

STS042-203-024 (22-30 Jan. 1992) --- Astronaut David C. Hilmers (right), STS-42 mission specialist, assists European Space Agency (ESA) payload specialist Ulf Merbold with the visual stimulator experiment on the Space Shuttle Discovery's middeck. This particular test is part of an ongoing study of the Space Adaptation Syndrome (SAS). Seated in a stationary mini-sled, Merbold (or any other subject for this test) stares at an umbrella-shaped rotating dome with a pattern of colored dots on its interior. While observing the rotating dome, the subject turns a knob to indicate his perception of body rotation. The strength of circular vection is calculated by comparing the signals from the dome and the knob. The greater the false sense of circular vection, the more the subject is relying on visual information instead of otolith information.

STS047-02-003 (12 - 20 Sept 1992) --- Astronaut N. Jan Davis, mission specialist, works at the Continuous Heating Furnace (CHF) in the Spacelab-J Science Module. This furnace provided temperatures up to 1,300 degrees Celsius and rapid cooling to two sets of samples concurrently. The furnace accommodated in-space experiments in the Fabrication of Si-As-Te:Ni Ternary Amorphous Semiconductor and the Crystal Growth of Compound Semiconductors. These were two of the many experiments designed and monitored by Japan's National Space Development Agency (NASDA).

STS057-39-001 (27 June 1993) --- This high angle shot inside the SPACEHAB module, onboard the Space Shuttle Endeavour, typifies the pace of activity conducted there during the ten-day STS-57 mission. Astronaut Janice E. Voss (foreground), mission specialist, works with biomaterials products, while astronauts Brian Duffy, pilot, and Nancy J. Sherlock, mission specialist, participate in other tasks.

STS-31 Mission Specialist (MS) Kathryn D. Sullivan monitors and advises ground controllers of the activity inside the Student Experiment (SE) 82-16, Ion arc - studies of the effects of microgravity and a magnetic field on an electric arc, mounted in front of the middeck lockers aboard Discovery, Orbiter Vehicle (OV) 103. Pilot Charles F. Bolden uses a video camera and an ARRIFLEX motion picture camera to record the activity inside the special chamber. A sign in front of the experiment reads "SSIP 82-16 Greg's Experiment Happy Graduation from STS-31." SSIP stands for Shuttle Student Involvement Program. Gregory S. Peterson who developed the experiment (Greg's Experiment) is a student at Utah State University and monitored the experiment's operation from JSC's Mission Control Center (MCC) during the flight. Decals displayed in the background on the orbiter galley represent the Hubble Space Telescope (HST), the United States (U.S.) Naval Reserve, Navy Oceanographers, U.S. Navy, and University of Kansas.

STS042-27-037 (22-30 Jan. 1992) --- Astronaut David C. Hilmers, STS-42 mission specialist, wearing a helmet assembly, sits in the Microgravity Vestibular Investigation (MVI) rotating chair. The scene is in the International Microgravity Laboratory (IML-1) science module aboard Discovery. Hilmers, a mission specialist, and six other crewmembers spent more than eight days in Earth-orbit conducting experiments. Hilmer's helmet assembly is outfitted with accelerometers to measure head movements and visors that fit over each eye independently to provide visual stimuli. The chair system has three movement patterns: "sinusoidal" or traveling predictably back and forth over the same distance at a constant speed; "pseudorandom" or moving back and forth over the varying distances; and "stepped" or varying speeds beginning and stopping suddenly.

STS064-45-014 (16 Sept. 1994) --- Backdropped against a massive wall of white clouds 130 nautical miles below, astronaut Mark C. Lee floats freely as he tests the new Simplified Aid for EVA Rescue (SAFER) system. The image was exposed with a 35mm camera from the shirt-sleeve environment of the space shuttle Discovery. Astronauts Lee and Carl J. Meade took turns using the SAFER hardware during their shared Extravehicular Activity (EVA) on Sept. 16, 1994. The test of SAFER is the first phase of a larger SAFER program whose objectives are to establish a common set of requirements for both space shuttle and space station program needs, develop a flight demonstration of SAFER, validate system performance and, finally, develop a production version of SAFER for the shuttle and station programs.

STS055-22-004 (26 April-6 May 1993) --- Four of the seven crew members who spent 10 days aboard the Space Shuttle Columbia are pictured during a brief shift overlap period in the Spacelab D-2 Science Module. Left to right are Jerry L. Ross, Ulrich Walter, Bernard A. Harris, Jr. and Hans Schlegel. Ross, STS-55 payload commander, is changing a sample in a materials processing furnace; Walter, a German payload specialist is in the midst of a baroreflex test and fellow payload specialist Schlegel assists mission specialist and physician Harris with a physiological test at the "Anthrorack".

STS040-211-020 (5-14 June 1991) --- Vestibular experiment activities were captured onboard Columbia's Spacelab Life Sciences (SLS-1) module in this 35mm scene. Astronaut James P. Bagian, STS-40 mission specialist, is in a rotating chair while wearing an accelometer and electrodes to record head motion and horizontal and vertical eye movements during the rotations. Payload specialist Millie Hughes-Fulford, lower left, assists with the test.

Astronauts Frank L. Culbertson Jr., STS-51 mission commander, and Daniel W. Bursch, mission specialist, are seen on Discovery's flight deck. The two were supporting operations free-flying Orbiting and Retrievable Far and Extreme Ultraviolet Spectrometer (ORFEUS) and its Shuttle Pallet Satellite (SPAS), pictured through the left window.

S83-35768 (18-24 June 1983) --- Astronaut Sally K. Ride, mission specialist for STS-7, uses a screw driver in order to clean out an air filtering system in the mid-deck of the Earth-orbiting Space Shuttle Challenger. Dr. Ride's constant wear garment bears some extras -- a cartoon of 35 busy astronauts around a Space Shuttle and the acronym TFNG, below which is written, "We deliver!" TFNG stands for thirty-five new guys, referring to the 1978 class of astronaut candidates (ASCAN) from which Dr. Ride and three of her crew members hail. The tiny two-word declarative in white lettering refers to the successful deployment of two communications satellites. This photograph was made with a 35mm camera.

STS055-106-090 (26 April- 6 May 1993) --- Hans Schlegel, one of two STS-55 payload specialists representing the German Aerospace Research Establishment (DLR) onboard the Space Shuttle Columbia, finds plenty of room to "spread out" while participating in a Tissue experiment. Astronaut Bernard A. Harris, Jr., mission specialist, monitors an experiment in the background.

STS055-45-017 (26 April-6 May 1993) --- Hans Schlegel (foreground) participates in the ongoing investigation of human physiology under microgravity conditions as he works out on the ergometer at the Anthrorack. Monitoring the "run" is astronaut Bernard A. Harris, Jr., STS-55 mission specialist. Schlegel is one of two payload specialists representing the German Aerospace Research Establishment (DLR) on the Spacelab D-2 mission.
