Feb.1969

The Manned Spacecraft Center (MSC) began an in-house study of a straight-wing, two-stage, fully reusable shuttle.

Apr. 1969

NASA and the Department of Defense (DoD) began a three-month joint study of how an earth orbital shuttle would serve the needs of both agencies. In June, the two organizations endorsed the idea of sharing the same design. In February 1970, a joint NASA-USAF committee was established.

Apr. 5, 1969

NASA Hq. established a Space Shuttle Task Group in the Office of Manned Space Flight (OMSF).

Sept. 1, 1969

President Nixon's Space Task Group, which was established to advise the President on space program goals for the next decade, recommended funding for a reusable shuttle craft to be operational by 1975-1977. Funding for a space station, the other half of an ambitious Space Transportation System that NASA wanted to implement during the next 10 years, was not approved.

Feb. 18, 1970

NASA issued a request for proposals (RFP) for phase B Shuttle definition studies, due in March. NR teamed with American Airlines and McDonnell Douglas with TRW to conduct their 11-month studies under phase B funding.

NASA adopted the external tank configuration for the orbiter, with reentry protection to be provided by an ablative thermal protection system.

Aug. 3, 1971

Pratt & Whitney requested an investigation by the General Accounting Office (GAO) of NASA's selection of Rocketdyne as builder of the Shuttle main engine. NASA's definitive contract to Rocketdyne was held pending the investigation; an interim 4-month contract was signed in September, with extensions granted in February and March 1972.

Sept. 1971

Phase B contractors presented their mid-term study results: Boeing&emdash;reusable Saturn V first stage with added tail, wings, and crew compartment with attached Grumman orbiter (44 m long, 27-m wingspan) with external tank; Boeing&emdash;Saturn IC stage expendable booster that supported orbiter with external tank, plus a solid propellant booster.
