Vanguard SLV-5, also called Vanguard Satellite Launch Vehicle Five hoped to be the third successful flight of the American Vanguard rocket following the successful Vanguard 2 satellite on rocket Vanguard SLV-4. Vanguard SLV-5 launched on April 14, 1959 02:49 GMT, from Launch Complex 18A at the Cape Canaveral Air Force Station. A momentary delay in first stage separation caused the second stage engine to ignite while still attached to the first stage. Pressure from the engine exhaust pushed the thrust chamber to the limit of the gimbal stops, breaking them and causing loss of attitude control in flight. The second stage tumbled and the resultant forces caused premature separation of the third stage and payload. Data was received from them until impact in the Atlantic Ocean eight minutes after liftoff.[1] [2] [3][4]Vanguard SLV-5 hoped to put into orbit two satellites: the Vanguard 3A satellite, a magnetometer, and a {{convert|30|in|abbr=on}} round inflatable sphere with an air density measurement device. Vanguard SLV-5 only reached an altitude of {{convert|100|km|abbr=on}}; the goal was {{convert|3840 |km|abbr=on}} to orbit.[5] [6] See also{{Portal|Spaceflight}}- Vanguard rocket
