Mission or Study ID: STS-5
The Shuttle's first operational mission also was the first space flight with four people on board: Commander Vance Brand, Pilot Robert Overmyer and Mission Specialists Joseph Allen and William Lenoir. Two commercial communications satellites, SBS-3 and Anik C-3, were launched into orbit from the cargo bay -- another first -- using the Payload Assist Module (PAM) upper stage designed for the Shuttle. One ''Get Away Special'' and three Shuttle Student Involvement Program (SSIP) experiments conducted. A planned spacewalk was canceled when problems developed with the two on board space suits.
Detailed Supplementary Objectives (DSOs)
Detailed Supplementary Objectives (DSOs) were performed on this mission. ADSO is a NASA-sponsored investigation that is performed by SpaceShuttle crewmembers, who serve as the test subjects. These studies aredesigned to require minimal crew time, power and stowage. Biomedical DSOsfocus on operational concerns, including space motion sickness,cardiovascular deconditioning, muscle loss, changes in coordination andbalance strategies, radiation exposure, pharmacokinetics and changes in thebody's biochemistry.
