| Full Description |
This photograph shows activities inside the science module during the Spacelab-1 (STS-9) mission. Left to right are Mission Specialist Robert Parker, Payload Specialist Byron Lichtenberg, Mission Specialist Owen Garriott, and Payload Specialist Ulf Merbold. The overall goal of the Spacelab-1 mission, the first mission of the Spacelab facility, were: (1) To verify the Spacelab system capability, (2) to obtain valuable scientific, applications, and technology data from a U.S./European multidisciplinary payload, and (3) to demonstrate the broad capability of Spacelab for scientific research. More than 70 experiments in 5 disciplines from 14 nations were conducted during the mission. The mission marked the the entry of non-astronaut persornel, called Payload Specialists, into space as working members of the crew. They are fellow scientists representing the international group of investigators using the mission. Mission Specialists are NASA astronauts who have broad scientific training. They operate various Orbiter-Spacelab systems, perform any required activity outside the spacecraft, and support investigations as needed. The Space Shuttle Orbiter Columbia that carried Spacelab-1 was operated by two other NASA astronauts serving as commander and pilot. The STS-9 mission, managed by the Marshall Space Flight Center, was launched on November 28, 1983. |

Onboard Space Shuttle Discovery (STS-42) the seven 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. Pictured are (clockwise from top),Commander Ronald J. Grabe, payload commander Norman E. Thagard, payload specialist Roberta L. Bondar, mission specialists William F. Readdy and David C. Hilmers, pilot Stephen S. Oswald and payload specialist Ulf Merbold. The rotating chair, used often in biomedical tests on the eight-day flight, is in center frame. |

| Full Description |
Astronaut Ulf Merbold on the stationary seat of the mini-sled, stares into an umbrella-shaped rotating dome with colored dots. Astronaut Merbold, assisted by astronaut David Hilmer, are conducting the Visual Simulator Experiment, a space physiology experiment. The Visual Stimulator Experiment measures the relative importance of visual and vestibular information in determining body orientation. When a person looks at a rotating visual field, a false sensation of self-rotation, called circularvection, results. In weightlessness, circularvection should increase immediately and may continue to increase as the nervous system comes to rely more on visual than vestibular cues. As Astronaut Merbold stares into the rotating dome with a pattern of colored dots and its interior, he turns a knob to indicate his perception of body rotation. The strength of circularvection is calculated by comparing signals from the dome and the knob. The greater the false sense of circularvection, the more the subject is relying on visual information instead of otolith information. The IML-1 mission was the first in a series of Shuttle flights dedicated to fundamental materials and life sciences research with the international partners. The participating space agencies included: NASA, the 14-nation European Space Agency (ESA), the Canadian Space Agency (CSA), the French National Center of Space Studies (CNES), the German Space Agency and the German Aerospace Research Establishment (DAR/DLR), and the National Space Development Agency of Japan (NASDA). Managed by the Marshall Space Flight Center, IML-1 was launched on January 22, 1992 aboard the Space Shuttle Orbiter Discovery (STS-42 mission). |

| Full Description |
The Space Shuttle was designed to carry large payloads into Earth orbit. One of the most important payloads is Spacelab. The Spacelab serves as a small but well-equipped laboratory in space to perform experiments in zero-gravity and make astronomical observations above the Earth's obscuring atmosphere. In this photograph, Payload Specialist, Ulf Merbold, is working at Gradient Heating Facility on the Materials Science Double Rack (MSDR) inside the science module in the Orbiter Columbia's payload bay during STS-9, Spacelab-1 mission. Spacelab-1, the joint ESA (European Space Agency)/NASA mission, was the first operational flight for the Spacelab, and demonstrated new instruments and methods for conducting experiments that are difficult or impossible in ground-based laboratories. This facility performed, in extremely low gravity, a wide variety of materials processing experiments in crystal growth, fluid physics, and metallurgy. The Marshall Space Flight Center had overall management responsibilities. |
