Saturn-Apollo 4 Spacecraft: (no serial number) Launch Vehicle: Saturn I Blk I SA-4 Launched: 28 Mar 1963

⇑ Mission List ⇑ Designation: Apollo S1 P LV1(N)-4 Description: 4th Saturn I Blk I suborbital, 1st stage live only

The S-I Saturn stage reached an altitude of 129 kilometers (80 statute miles) and a peak velocity of 5,906 kilometers (3,660 miles) per hour. This was the last of four successful tests for the first stage of the Saturn I vehicle. After 100 seconds of flight, No. 5 of the booster's eight engines was cut off by a preset timer. That engine's propellants were rerouted to the remaining seven, which continued to burn. This experiment confirmed the "engine-out" capability that MSFC engineers had designed into the Saturn I.
