Spacelab
Encyclopedia
Spacelab was a reusable laboratory used on certain spaceflight
Spaceflight
Spaceflight is the act of travelling into or through outer space. Spaceflight can occur with spacecraft which may, or may not, have humans on board. Examples of human spaceflight include the Russian Soyuz program, the U.S. Space shuttle program, as well as the ongoing International Space Station...

. The laboratory consisted of multiple components, including a pressurized module, an unpressurized carrier and other related hardware housed in the Shuttle's cargo bay. The components were arranged in various configurations to meet the needs of each spaceflight.

Spacelab components flew on 22 Shuttle missions between November 1983 and April 1998. Spacelab allowed scientists to perform experiments in microgravity in Earth orbit.

In addition to the laboratory module, the complete set also included five external pallets for experiments in vacuum, built by British Aerospace

Eight flight configurations were qualified though more could be assembled.

Habitable module

The Spacelab Module consists of a cylindrical main laboratory configurable as Short or Long Module flown in the rear of the Space Shuttle cargo bay, connected to the crew compartment by a tunnel. The laboratory had an outer diameter of 4.12 m, and each segment a length of 2.7 m. Most of the time two segments were used in forming the Long Module configuration.

Two habitable modules were built, named LM1 and LM2. LM2 is now on display in the Bremenhalle exhibition in the Bremen Airport

Pallet

The Spacelab Pallet is a U-shaped platform for mounting instrumentation, large instruments, experiments requiring exposure to space, and instruments requiring a large field of view, such as telescopes. The pallet has several hard points for mounting heavy equipment. The pallet can be used in single configuration or stacked end to end in double or triple configurations. Up to five pallets can be configured in the Space Shuttle cargo bay by using a double plus triple pallet.

A Spacelab Pallet was transferred to the Swiss Museum of Transport for permanent display on 5 March 2010. The Pallet, nicknamed Elvis, was used during the eight-day STS-46 mission, 31 July - 8 August 1992, when ESA astronaut Claude Nicollier was on board Shuttle Atlantis to deploy ESA's European Retrievable Carrier (Eureca) scientific mission and the joint NASA/Italian Space Agency

 Tethered Satellite System (TSS-1). The Pallet carried TSS-1 in the Shuttle's cargo bay.

Igloo

On spaceflight where a habitable module was not flown, but pallets were flown, a pressurized cylinder known as the igloo carried the subsystems needed to operate the Spacelab equipment. The igloo was 10 feet tall, had a diameter of 5 feet, and weighed 2500 lbs. Two igloo units were manufactured, both by Belgium company SABCA

, and both were used on spaceflight. An igloo component was flown on Spacelab 2, Astro-1, ATLAS-1, ATLAS-2, ATLAS-3, and Astro-2.

Other components

Other Spacelab elements include the tunnel, and the Instrument Pointing System (IPS) tailored to the pallet interfaces for precise pointing to space or earth targets.

Spacelab missions

The Spacelab components were used on 25 shuttle flights, but the components were decommissioned in 1998 except the pallets. Science work was to be moved to the International Space Station
