In their own words A change of plans in charge of planning and monitoring the maneuvers to remove the command module from lunar orbit and head it back toward Earth. He recalled an unplanned schedule change after the lunar module (LM) lifted off from the Moon and rejoined the command module in lunar orbit. On Apollo 11, once you get all the rocks and stuff out and close out the LM, you really don’t want to hang around it. They had another rev to go before they were going to close the hatch. Well, they come around the corner [from the back side of the Moon] and the hatch was already closed. We go, hey, we don’t really want to stay on this thing, because it’s got the engine with things armed, and it’s ready to do stuff. So we had to separate one rev early. We would deorbit that thing out of lunar orbit, and then we’d check the seismometers from the ground on the Moon’s surface. This is an excerpt from the book, “Space Pioneers: In Their Own Words” which was authored by Loretta Hall and released last month. The book is available for purchase at www.amazon.com.
