These objectives were satisfactorily accomplished..The spacecraft subsystems operated satisfactorily in all respects. Performance of the guidance and control subsystems was equal to or better than predictions. All sequencing and computat

Apollo 4: The first test of the Saturn V 9 November 1967,ional operations performed by the guidance computer were correct. The environmental control subsystem maintained the cabin pressure and temperature within required limits. The thermal protection subsystem survived the lunar entry environment satisfactorily. The erosion of the heat shield was between 2.5 and 7.6 mm.

Book 2006ew the planned lunar landing of a three-man spaceship named Apollo in the mid-1970s. In 1962, it was decided that a specialized vehicle would accompany the main spacecraft, to make the lunar landing while the mothership remained in lunar orbit. To send these vehicles to the Moon would require the de

AS-201: The first flight of the Saturn IB: a CSM on a ballistic arc 26 February 1966,ome of the flight measurements were corrupted by an electrical short circuit. In order to provide the time to diagnose and rectify the fault in the SPS engine, AS-202 was rescheduled after AS-203, which was to be an S-IVB development flight that would not carry a spacecraft.

AS-203: The second flight of the Saturn IB: evaluating the S-IVB 5 July 1966,g coasting flight provided sufficient ullage to maintain the hydrogen settled in its tank, as would be required on a Saturn V dispatching a lunar mission. The simulated restart verified the chilldown and recirculation systems of the J-2 engine. AS-203 was therefore a successful test of the S-IVB sta
