Vanguard SLV-1

Vanguard SLV-1

Vanguard SLV-1, also called Vanguard Satellite Launch Vehicle 1 hoped to be the second successful flight of the American Vanguard rocket following successful Vanguard 1 satellite on rocket Vanguard TV-4. Vanguard SLV-1 launched on May 27, 1958 03:46 GMT. It was launched from Launch Complex 18A at the Cape Canaveral Air Force Station. The rocket was unsuccessful in its attempt to place an unnamed satellite into earth orbit. There was improper third stage trajectory, thus the satellite failed to achieve orbit. The underlying cause of the error is unknown. This was set back in the space race between the USA and Soviet Union.[1] [2] [3][4] [5]

Vanguard SLV-1 hoped to put in to orbit the Vanguard 2B satellite, a Lyman Alpha satellite, with a magnetosphere measurement device. The satellite payload was 10 kg (22 lb). The rocket reached an apogee (the highest point of the rocket's flight) of 3,500 km (2,200 mi). [6]
