1969-018B
SA-504 was launched at 1600:00 on 1969 Mar 3. The S-IVB entered earth orbit at 1611:15, and Apollo 9 separated from it at 2018. The S-IVB restarted at 2045:47, entering a 207 x 3087 km x 32.6 deg orbit. A third burn at 2207:19 sent the stage on an escape trajectory to solar orbit. The burn involved an experimental extended preburn fuel supply, and several anomalies were reported; pressurization was lost in the engine system, losing about 2 km/s of velocity. At MECO-3 the velocity was 9.628 km/s at an altitude of 2283 km, and C3 was 824712 m2/s2. The S-IVB reached a 325.8d, 128.561 x 148.678 Mkm x 24.39 deg solar orbit instead of the planned 240d, 76.808 x 149.340 Mkm x 22.27 deg orbit.
