It details the 80 days preceding the launching of the IGY Satellite 1958 Alpha which was the “free world’s” first Earth satellite. After many design and planning meetings between the US Army, scientists from the Jet Propulsion Laboratory (JPL) at the California Institute of Technology, and the United States Army Ballistic Missile Agency the satellite was officially launched from Cape Canaveral on January 31st. The film’s story is by Irl E. Newland and Norman E. White and produced by Raphael S. Wolf Studios, Inc. Hollywood. The film also features Philip Callahan as executive producer and Jack Taylor as editor. United States of America War Office U.S. Army seal (0:07). Animation of shooting star and title page (0:13).

Explorer was the first satellite of the United States, following the first two satellites the previous year; the Soviet Union’s Sputnik 1 and 2, beginning the Cold War Space Race between the two nations. Explorer 1 was launched on January 31, 1958 at 22:48 Eastern Time atop the first Juno booster from LC-26 at the Cape Canaveral Missile Annex, Florida. It was the first spacecraft to detect the Van Allen radiation belt, returning data until its batteries were exhausted after nearly four months. It remained in orbit until 1970, and has been followed by more than 90 scientific spacecraft in the Explorer series. The Juno I was a four-stage American space launch vehicle, used to launch lightweight payloads into low Earth orbit. The launch vehicle was used between January 1958 to December 1959. The launch vehicle was a member of the Redstone launch vehicle family, and was derived from the Jupiter-C sounding rocket. It is commonly confused with the Juno II launch vehicle, which was derived from the PGM-19 Jupiter medium-range ballistic missile. In 1958, a Juno I launch vehicle was used to launch America’s first satellite, Explorer 1.
