German Space Operations Center

Until 1985, the Oberpfaffenhofen site of the then German Aerospace Research and Testing Institute (DFVLR) increasingly concentrated on spaceflight. The human spaceflight received special attention. Indeed, the GSOC then accompanied two crewed missions: During STS-61-A in 1985, GSOC took over the control of the Spacelab, while flight control continued from NASA's Lyndon B. Johnson Space Center was acquired. For the first time, the Payload Operation Control Center (POCC) of a US space mission was directed outside of NASA. This also means that, for the first time, a human spaceflight was (partially) monitored from outside the USA or the Soviet Union.[1] During this mission, then Bavarian Prime Minister Franz Josef Strauss announced on 5 November 1985 an extensive investment program with which the role of Oberpfaffenhofen in European spaceflight should be increased.

But the failure of Ariane 3 in 1985 and the Challenger disaster in 1986 slowed the development of the Oberpfaffenhofen and thus the GSOC. Nevertheless, the investment program also gave the GSOC a new building (Building 140), the construction began on 4 April 1989.

In 1993, GSOC accompanied the entire operation with STS-55 and had full payload control via the Spacelab. This was the first time that there was unfiltered access to all data.
