Biosatellite 1, also known as Biosat 1 and Biosatellite A, was the first mission in NASA's Biosatellite program. It was launched on December 14, 1966, by a Delta G rocket from Launch Complex 17A of the Cape Canaveral Air Force Station[3] into an orbit with a 296-kilometre (184 mi) perigee, 309-kilometre (192 mi) apogee, and 33.5 degrees of orbital inclination, with a period of 90.5 minutes.[4]
Biosatellite 1 was carrying several specimens for studying the effects of the space environment on biological processes. Prior to reentry, the entry capsule separated from the satellite bus properly, but the deorbit motor failed to ignite, leaving it stranded in a slowly decaying orbit. It re-entered and disintegrated on February 15, 1967.
