Explorer S-66 (also called BE-A, acronym of Beacon Explorer-A), was a NASA satellite launched on 19 March 1964 by means of a Thor-Delta B launch vehicle, but it could not reach orbit due to a vehicle launcher failure.[1]
Spacecraft
Beacon Explorer-A was a small ionospheric research satellite instrumented with an electrostatic probe, a 20-, 40-, and 41-Hz ionospheric radio beacon, a passive laser tracking reflector, and a navigation experiment. Its primary objective was to obtain worldwide observations of total electron content between the spacecraft and the Earth. The spacecraft was an octagonal right prism Шаблон:Cvt-diameter terminated on top with a truncated octagonal pyramid on which the laser reflectors were mounted. Appended were four hinged paddles carrying solar cells. Each paddle was Шаблон:Cvt.[1]
Launch
During the third stage operation, a malfunction of unidentified origin prevented successful orbit. Satellite and third stage descent were in the south Atlantic Ocean with no useful scientific data obtained.[1]
