Saturn 1B Booster for Apollo-Soyuz Test Project Poster

The Saturn 1B booster for the United States mission of the Apollo Soyuz Test Project is shown on its mobile launcher in a Vehicle Assembly Building high bay with a boilerplate Apollo spacecraft installed atop the instrument unit. The encapsulated Apollo spacecraft, docking module and docking adapter that will be launched atop the Chrysler- built booster will replace the boiler plate spacecraft prior to rollout of the space vehicle to Complex 39's Pad B. Primary Apollo-Soyuz Test Project mission objectives were to evaluate the docking and undocking of an Apollo spacecraft with a Soyuz, and determine the adequacy of the onboard orientation lights and docking target; evaluate the ability of astronauts and cosmonauts to make inter-vehicular crew transfers and the ability of spacecraft systems to support the transfers: evaluate the Apollo's capability of maintaining attitude-hold control of the docked vehicles and performing attitude maneuvers; measure quantitatively the effect of weightlessness on the crews' height and lower limb volume, according to length of exposure to zero-g; and obtain relay and direct synchronous-satellite navigation tracking data to determine their accuracy for application to Space Shuttle navigation-system design. The objectives were successfully completed, and the mission was adjudged successful on August 15, 1975.
