Explorer 2 (EXPLR2) was to be a repeat of the Explorer 1 mission. However, due to a failure in the rocket during launch, the spacecraft did not reach orbit.
Explorer 2 was launched from Cape Canaveral Air Force Station LC-26A in Florida on March 5, 1958 at 18:28 UTC, by a Jupiter-C launch vehicle. The Jupiter-C had its origins in the United States Army's Project Orbiter in 1954. The project was canceled in 1955, when the decision was made to proceed with Project Vanguard.
Following the launch of the Soviet Sputnik 1 on October 4, 1957, the Army Ballistic Missile Agency (ABMA) was directed to proceed with the launching of a satellite using the Jupiter-C, which had already been flight-tested in nose-cone re-entry tests for the Jupiter IRBM (intermediate-range ballistic missile). Working closely together, ABMA and Jet Propulsion Laboratory (JPL) completed the job of modifying the Jupiter-C and building Explorer 1 in 84 days.

Famous quotes containing the word explorer:
“Treading the soil of the moon, palpating its pebbles, tasting the panic and splendor of the event, feeling in the pit of one’s stomach the separation from terra ... these form the most romantic sensation an explorer has ever known ... this is the only thing I can say about the matter. The utilitarian results do not interest me.”
—Vladimir Nabokov (1899–1977)
