[edit] Actual Times From Apollo by the Numbers (NASA)

  • After inflight systems checks, the 351.04-second translunar injection maneuver (second S-IVB firing) was performed at 003:12:36.60. The
    S-IVB engine shut down at 003:18:27.64 and translunar injection occurred ten seconds later at a velocity of 35,555.3 ft/sec after two Earth orbits lasting 3 hours 6 minutes 44.99 seconds.
  • At 003:42:27.6, the CSM was separated from the S-IVB stage, transposed, and docked at 003:57:10.7. During docking, there were indications of a ring latch malfunction. The LM was pressurized, the hatch removed, and troubleshooting revealed that the handles for latches 7, 9, and 10 were not locked. All were manually set and the docked spacecraft were ejected from the S-IVB at 004:45:02.3. A 79.9-second separation maneuver was performed at 005:03:01.1.
  • The S-IVB tanks were vented at 006:09:59.8, and the auxiliary propulsion system was fired for 98.2 seconds to target the S-IVB for a lunar impact. A second, 102.2-second maneuver was performed at 011:14:59.8. The S-IVB impacted the lunar surface at 086:59:42.3. The impact point was latitude 4.21° south and longitude 12.37° west, 84 n mi from the target point, 183 n mi from the Apollo 12 seismometer, 85 n mi from the Apollo 14 seismometer, 557 n mi from the Apollo 15 seismometer, and 459 n mi from the Apollo 16 seismometer. The impact was recorded by all four instruments. At impact, the S-IVB weighed 30,712 pounds and was traveling 8,366 ft/sec.
  • The 2-hour 40-minute launch delay caused ground controllers to modify Apollo 17’s trajectory so that it would arrive at the Moon at the originally scheduled time. They shortened the translunar coast time by having the crew make a 1.73-second 10.5 ft/sec midcourse correction at 035:29:59.91.
  • The commander and lunar module pilot transferred to the LM at 040:10. At ingress, it was discovered that #4 docking latch was not properly latched. The command module pilot moved the latch handle between 30° and 45°, disengaging the hook from the docking ring. After discussion with ground control, it was decided to curtail further action on the latch until the second LM activation. The remainder of the LM housekeeping was nominal and the LM was closed out at 042:11.
  • The second LM housekeeping session commenced at 059:59 and was completed at 062:16. All LM systems checks were nominal. During the LM housekeeping period, the command module pilot performed troubleshooting on the docking latch #4 problem experienced during the first session. Following instructions from the ground controllers, he stroked the latch handle and succeeded in cocking the latch. The latch was left in the cocked position for the CSM/LM rendezvous.
  • The SM scientific instrument module bay door was jettisoned at 081:32:40.
  • At 086:14:22.60, at an altitude of 76.8 n mi above the Moon, the service propulsion engine was fired for 393.16 seconds to insert the spacecraft into a lunar orbit of 170.0 by 52.6 n mi. The translunar coast had lasted 83 hours 2 minutes 18.11 seconds.
