STS042-78-061 (22-30 Jan. 1992) --- The seven STS-42 crewmembers pose for a traditional in-space portrait in the shirt-sleeve environment of the International Microgravity Laboratory (IML-1) science module in the shuttle's cargo bay. (Hold picture with index numbers at top.) David C. Hilmers, mission specialist, is at top center of the 70mm image. Others pictured are (clockwise) Ronald J. Grabe, mission commander; William F. Readdy; mission specialist; Ulf Merbold, European Space Agency (ESA) payload specialist; Norman E. Thagard, payload commander; Stephen S. Oswald, pilot; and Roberta L. Bondar, Canadian payload specialist. The rotating chair, used often in biomedical tests on the eight-day flight, is (partially obscured) in center frame.

STS047-46-027 (12-20 Sept. 1992) --- Astronauts N. Jan Davis (left) and Mae C. Jemison, STS-47 mission specialists, prepare to deploy the Lower Body Negative Pressure (LBNP) apparatus in this 35mm frame photographed in the Science Module aboard the Earth-orbiting Space Shuttle Endeavour. Making their first flight in space, the two were joined by four other NASA astronauts and a Japanese payload specialist for eight days of research. The Spacelab-J mission is a joint effort between Japan and the United States of America.

STS055-233-019 (26 April-6 May 1993) --- Terence T. (Tom) Henricks, STS-55 pilot, wears a special collar for a space adaptation experiment in the science module onboard the Earth-orbiting Space Shuttle Columbia. The Baroreflex (BA) experiment is designed to investigate the theory that light-headedness and a reduction in blood pressures upon standing after landing may arise because the normal reflex system regulating blood pressure behaves differently after having adapted to a microgravity environment. These space-based measurements of the baroreflex will be compared to ground measurements to determine if microgravity affects the reflex.

STS047-230-030 (12 - 20 Sept 1992) --- Astronauts Mae C. Jemison (left) and N. Jan Davis, mission specialists, are pictured in the Spacelab-J science module preparing to conduct a session with the Lower Body Negative Pressure (LBNP) experiment. The two joined four other NASA astronauts and a payload specialist representing Japan's National Space Development Agency (NASDA) aboard the Earth-orbiting Space Shuttle Endeavour for eight days of Spacelab-J research.

STS040-30-008 (5-14 June 1991) --- Astronaut Tamara E. Jernigan, after applying a blood pressure cuff to an experiment, watches it in operation. The experiment is the intravenous infusion pump. The device is being considered for use on Space Station Freedom's Health Maintenance Facility. Dr. Jernigan is one of seven crew members supporting the nine-day Spacelab Life Sciences (SLS-1) mission aboard the Earth-orbiting Space Shuttle Columbia.

S85-26582 (Feb 1985) --- Training on the rebreathing assembly, astronaut James P. Bagian, STS-40 mission specialist, inhales a predetermined gas composition. A gas analyzer mass spectrometer determines the composition of the gases he exhales. The rebreathing assembly and gas analyzer system are part of an investigation that explores how lung function is altered. Dr. Bagian will be joined by two other mission specialists, the mission commander, the pilot and two payload specialists for the scheduled 10-day Spacelab Life Sciences-1 (SLS-1) mission. The flight is totally dedicated to biological and medical experimentation.

S85-26553 (Feb 1985) --- STS-40/SLS-1 payload specialist Millie Hughes-Fulford sits strapped in the special device scientists have developed for determining mass on orbit. As the chair swings back and forth, a timer records how much the crewmember's mass retards the chair's movement. Dr. Hughes-Fulford will be joined by three mission specialists, the mission commander, the pilot and a second payload specialist for the scheduled 10-day Spacelab Life Sciences-1 (SLS-1) mission. The flight is totally dedicated to biological and medical experimentation.

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.

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".

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.

S85-26571 (Feb 1985) --- Wearing a special collar, Millie Hughes-Fulford, payload specialist, practices medical test operations scheduled for the Spacelab Life Sciences (SLS-1) mission. Robert Ward Phillips, backup payload specialist, looks on. The collar, called the baroflex neck pressure chamber, is designed to stimulate the bioceptors in the carotid artery, one of the two main arteries that supply blood to the head.
