Space Rocket History #339 – Apollo 15 – The Launch

The last face they saw was Guenter’s, smiling and waving an enormous crescent wrench. Then the heavy hatch closed with a deep thunk.

Space Rocket History #338 – Apollo 15 – CDR Dave Scott Part 2 & The Postal Covers Incident

As Command Module Pilot for Apollo 9, Scott’s responsibilities were heavy. The Lunar Module was to separate from the Command and Service Module during the mission; if it failed to return, Scott would have to run the entire spacecraft for reentry, normally a three-man job.

Space Rocket History #304 – Apollo 14 – Commander Alan B. Shepard Jr. – Part 4

Even with all the problems, Shepard piloted the Lunar Module Antares to the most accurate landing of the entire Apollo program. Shepard became the fifth and, at the age of 47, the oldest man to walk on the Moon, and the only one of the Mercury Seven astronauts to do so.

Space Rocket History #197 – Apollo 10 – Ascent Stage Rendezvous, Docking & Jettisoning

As the lunar module approached, Young saw it through his sextant at a distance of 259 kilometers. Stafford and Cernan got a radar lock on the command module shortly after the insertion burn and watched with interest as the instrument measured the dwindling gap between the vehicles and demonstrated the theories of orbital mechanics in actual practice. Cernan especially liked the steady communications that kept both crews aware of what was happening.

Space Rocket History #196 – Apollo 10 – Lunar Module Out of Control

The abort system had two basic control modes, “attitude hold” and “automatic.” In automatic, the computer would take over the guidance and start looking for the command module, which was certainly not what the crew intended to do at that moment. While correcting for a minor yaw-rate-gyro disturbance, the astronauts  accidentally switched the spacecraft to the automatic mode, resulting in frantic gyrations.
