This illustration depicts the configuration of the Spacelab-2 in the cargo bay of the orbiter. Spacelab was a versatile laboratory carried in the Space Shuttle's cargo bay for scientific research flights. Each Spacelab mission had a unique design appropriate to the mission's goals. A number of Spacelab configurations could be assembled from pressurized habitation modules and exposed platforms called pallets. Spacelab-2 was the first pallet-only mission. One of the goals of the mission was to verify that the pallets' configuration was satisfactory for observations and research. Except for two biological experiments and an experiment that used ground-based instruments, the Spacelab-2 scientific instruments needed direct exposure to space. On the first pallet, three solar instruments and one atmospheric instrument were mounted on the Instrument Pointing System, which was being tested on its first flight. The second Spacelab pallet held a large double x-ray telescope and three plasma physics detectors. The last pallet supported an infrared telescope, a superfluid helium technology experiment, and a small plasma diagnostics satellite. The Spacelab-2 mission was designed to capitalize on the Shuttle-Spacelab capabilities, to launch and retrieve satellites, and to point several instruments independently with accuracy and stability. Spacelab-2 (STS-51F, 19th Shuttle mission) was launched aboard Space Shuttle Orbiter Challenger on July 29, 1985. The Marshall Space Flight Center had overall management responsibilities of the Spacelab missions.

This photograph shows the Instrument Pointing System (IPS) for Spacelab-2 being deployed in the cargo bay of the Space Shuttle Orbiter Challenger. The European Space Agency (ESA) developed this irnovative pointing system for the Spacelab program. Previously, instruments were pointed toward particular celestial objects or areas by maneuvering the Shuttle to an appropriate attitude. The IPS could aim instruments more accurately than the Shuttle and kept them fixed on a target as the Shuttle moved. On the first pallet, three solar instruments and one atmospheric instrument were mounted on the IPS. Spacelab-2 was the first pallet-only mission. One of the goals of the mission was to verify that the pallets' configuration was satisfactory for observations and research. Except for two biological experiments and an experiment that used ground-based instruments, the Spacelab-2 scientific instruments needed direct exposure to space. The Spacelab-2 mission was designed to capitalize on the Shuttle-Spacelab capabilities to carry very large instruments, launch and retrieve satellites, and point several instruments independently with accuracy and stability. Spacelab-2 (STS-51F, 19th Shuttle mission) was launched on July 29, 1985 aboard the Space Shuttle Orbiter Challenger. The Marshall Space Flight Center had overall management responsibilities of the Spacelab missions.

STS-65 Mission Specialist Carl E. Walz floats above center aisle equipment in the International Microgravity Laboratory 2 (IML-2) spacelab science module. Walz has just entered the IML-2 module via the spacelab tunnel (note hatch opening behind him). The tunnel connects the IML-2 module with Columbia's, Orbiter Vehicle (OV) 102's, crew compartment. Walz along with five other NASA astronauts and a Japanese payload specialist spent more than two weeks in Earth orbit conducting IML-2 experiments. This photo was among the first released by NASA following IML-2.

While instruments on the pallets in the payload bay observed the universe, biological experiments were performed in the middeck of the Shuttle Orbiter Challenger. Studying life processes in a microgravity environment can shed new light on the functioning of biological systems on Earth. These investigations can also help us understand how living organisms react to prolonged weightlessness. One such experiment was the vitamin D metabolites and bone demineralization experiment. This investigation measured the vitamin d metabolite levels of crew members to gain information on the cause of bone demineralization and mineral imbalance that occur during prolonged spaceflight as well as on Earth. Research into the biochemical nature of vitamin D has shown that the D-metabolites play a major role in regulating the body's calcium and phosphorus levels. One major function of the most biologically active vitamin D metabolite is to regulate the amount of calcium absorbed from the diet and taken out of bones. This investigation had two phases. The first was the developmental phase, which included extensive testing before flight, and the second, or final phase, involved the postflight analysis of the crew's blood samples. This photograph shows a blood draw test kit and centrifuge used for the experiment aboard the Spacelab-2. Marshall Space Flight Center had management responsibilities of all Spacelab missions.

This STS-51F mission onboard Photograph shows some of the Spacelab-2 instruments in the cargo bay of the Orbiter Challenger. The Plasma Diagnostics Package (PDP). shown at the end of the Remote Manipulator System (RMS), used instruments on a subsatellite to study natural plasma processes, orbiter-induced plasma processes, and beam plasma physics. Fourteen instruments were mounted on the PDP for measurements of various plasma characteristics. The X-ray Telescope (XRT), is at the front. The goal of this investigation was to image and examine the X-ray emissions from clusters of galaxies in order to study the mechanisms that cause high-temperature emissions and to determine the weight of galactic clusters. The Small Helium-Cooled Infrared Telescope (IRT) is at the right behind the XRT. The objective of this investigation was to measure and map diffused and discrete infrared astronomical sources while evaluating the Space Shuttle as a platform for infrared astronomy. At the same time, a new large superfluid helium dewar system for cooling the telescope was evaluated. The egg-shaped Cosmic Ray Nuclei experiment (CRNE) is shown at the rear. This investigation was to study the composition of high-energy cosmic rays by using a large instrument exposed to space for a considerable period of time. Spacelab-2 (STS-51F, 19th Shuttle mission) was launched aboard the Space Shuttle Orbiter Challenger on July 29, 1985.

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.

Typical metal sample that was processed by TEMPUS (Tiegelfreies Elektromagnetisches Prozessieren Unter Schwerelosigkeit), an electromagnetic levitation facility developed by German researchers and flown on the IML-2 and MSL-1 and 1R Spacelab missions. Electromagnetic levitation is used commonly in ground-based experiments to melt and then cool metallic melts below their freezing points without solidification occurring. Sample size is limited in ground-based experiments. Research with TEMPUS aboard Spacelab allowed scientists to study the viscosity, surface tension, and other properties of several metals and alloys while undercooled (i.e., cooled below their normal solidification points). The sample is about 1 cm (2/5 inch) in diameter.

KENNEDY SPACE CENTER, FLA. - The Space Shuttle Columbia climbs a golden tower into a royal blue sky dusted with clouds. The 58th Shuttle flight lifted off from Launch Pad 39B at 10:53:10 a.m. EDT, beginning the longest mission planned in Shuttle program history: two weeks. The Extended Duration Orbiter STS-58 mission will allow the seven-member crew to delve extensively into a number of experiments investigating the adaptation of the human body to space. Spacelab Llife Sciences-2 is the second Spacelab mission dedicated solely to life sciences research.

A steel hemisphere was at the core of the Geophysical Fluid Flow Cell (GFFC) that flew on two Spacelab missions. It was capped by a sapphire dome. Silicone oil between the two played the part of a steller atmosphere. An electrostatic field pulled the oil inward to mimic gravity's effects during the experiments. The GFFC thus produced flow patterns that simulated conditions inside the atmospheres of Jupiter and the Sun and other stars. GFFC flew on Spacelab-3 in 1985 and U.S. Microgravity Laboratory-2 in 1995. The principal investigator was John Hart of the University of Colorado at Boulder. It was managed by NASA's Marshall Space Flight Center. (Credit: NASA/Marshall Space Flight Center)

Positioned on the Spacelab pallet amidst other hardware, the Astro-2 payload is in its operational mode. Visible here are the Instrument Pointing System (IPS), Hopkins Ultraviolet Telescope (HUT), Star Tracker (ST), Ultraviolet Imaging Telescope (UIT), Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE), and Integrated Radiator System (IRS). At this angle, the Optical Sensor Package (OPS) is not seen. The Igloo, which supports the package of experiments, is in center foreground. Two Get-Away Special (GAS) canisters are in lower left foreground. The Extended Duration Orbiter (EDO) pallet, located aft of the cargo bay, is obscured by the Astro-2 payload. The Endeavour was 190 nautical miles above Earth.

STS073-101-018 (20 October-5 November 1995) --- Payload specialist Fred W. Leslie maneuvers his body to a position conducive to research at the Crystal Growth Furnace (CGF) aboard the science module in the cargo bay of the Earth-orbiting Space Shuttle Columbia. Crystallization has been discovered to be more effectively studied in the weightless environment of space than on Earth, because the gravity-induced phenomena that obscure or change the process or change the process are greatly reduced or eliminated. Leslie was joined by a second guest researcher and five NASA astronauts for 16 full days of in-space research in support of the United States Microgravity Laboratory (USML-2) mission.

While instruments on the pallets in the payload bay observed the universe, biological experiments were performed in the middeck of the Shuttle Orbiter Challenger. Studying life processes in a microgravity environment can shed new light on the functioning of biological systems on Earth. These investigations can also help us understand how living organisms react to prolonged weightlessness. One such experiment was the vitamin D metabolites and bone demineralization experiment. This investigation measured the vitamin D metabolite levels of crew members to gain information on the cause of bone demineralization and mineral imbalance that occur during prolonged spaceflight as well as on Earth. Research into the biochemical nature of vitamin D has shown that the D-metabolites play a major role in regulating the body's calcium and phosphorus levels. One major function of the most biologically active vitamin D metabolite is to regulate the amount of calcium absorbed from the diet and taken out of bones. This investigation had two phases. The first was the developmental phase, which included extensive testing before flight, and the second, or final phase, involved the postflight analysis of the crew's blood samples. This photograph shows astronaut Story Musgrave in the middeck of the Shuttle Orbiter Challenger, attending to the blood samples he collected from crew members for the experiment.
