Biosatellite 1, also known as Biosat 1 and as Biosatellite A, was a first artificial satellite unmanned U.S. belonging to Biosatellite program for biological research. It was released on December 14, 1966 by a rocket Delta G from Launch Complex 17A of the Cape Canaveral Air Force Station. Biosatellite 1 was the first series Biosatellite satellites. It was released in an initial orbit of 296 kilometres (184 mi) perigee 309 kilometres (192 mi) apogee and 33.5 degrees of orbital inclination, with period 90.5 minutes.
Biosatellite 1 was carrying several specimens for the study of the effects of the space environment on biological processes. The capsule was returning to land separated from the vehicle properly, but its rocket malfunctioned, leaving it stranded in a slowly decaying orbit. It re-entered and disintegrated on February 15, 1967.
