The Space Task Group was a working group of NASA engineers created in 1958, tasked with superintending America's manned spaceflight programs. It was headed by Robert Gilruth and based at the Langley Research Center in Hampton, Virginia. After President John F. Kennedy set the goal of the Apollo Program to land men on the Moon in 1961, NASA decided a much larger organization and a new facility was required to perform the Task Group's function, and it was transformed into the Manned Spacecraft Center (now the Lyndon B. Johnson Space Center), located in Houston, Texas.
Created on November 5, 1958, the Space Task Group was headed by Robert Gilruth. Originally it consisted of 45 people, including eight secretaries and "computers" (the term for women who ran calculations on mechanical adding machines). Of its 37 engineers, 27 were from Langley Research Center and ten had been assigned from Lewis Research Center in Cleveland, Ohio. Original members of the group included Charles Donlan, Gilruth's deputy; Max Faget, head of engineering; Chuck Mathews, head of flight operations; Chris Kraft, also in flight operations; and Glynn Lunney, who at 21 was the youngest member of the group. The head of the public affairs office was John "Shorty" Powers.
In 1959, the group was expanded by the addition of 32 engineers from Canada, who had been left without jobs when the Avro Arrow project was cancelled. These new additions, Canadians and some British, included Jim Chamberlin, George Harris, John Hodge, Owen Maynard, Bryan Erb, Rodney Rose and Tecwyn Roberts.
After President John F. Kennedy set the national goal on May 25, 1961 of landing men on the Moon by the end of the 1960s, it became clear to NASA administrator James E. Webb that Gilruth would need a much larger organization and facilities, in fact a new dedicated NASA center, to administrate US manned space programs. Webb got the approval of Kennedy and the Congress, and in August 1961 appointed a team to select a site for the new center. On September 19, Webb announced the new Manned Spacecraft Center (MSC) would be built on a Houston, Texas site donated by Rice University. Gilruth immediately began the transition of his Task Group into the new MSC, planning his increased staff organization and its move to Houston, using temporary leased office and test facility space on 12 sites while the new facility was being built. By September 1962, his organization was moved to Houston and construction had begun, effectively marking the end of the Task Group. The MSC facility was completed in September 1963.
