Saturn S-IVB-507

  1969-099B


SA-507 was launched on 1969 Nov 14 at 1622. The TLI burn was at 1909, and Apollo 12 separated at 2035. The propellants were dumped and the stage flew past the Moon at 5724 km on 1969 Nov 18 at 0610. A trajectory error left S-IVB-507 in a 165000 x 850000 km Earth orbit instead of the intended solar orbit.

The closest apporach of 5715 km above the lunar surface was not close enough to accelerate the stage to escape; an inaccurate state vector meant that the commanded ullage burn was too long. The flyby increased the geocentric speed of the stage by 0.548 km/s.
