The Apollo Lunar Module (LM / ˈ l ɛ m /), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only ...
According to Jones, "Three weeks after the Apollo 7 crew returned, NASA administrator Thomas Paine green-lighted Apollo 8 to launch in late December and orbit the Moon. Apollo 7 had delivered NASA from its trial by fire—it was the first small step down a path that would lead another crew, nine months later, to the Sea of Tranquility." [28]
Engineers at Arnold Air Base with an Apollo service module engine Apollo Service Module Propulsion System The service propulsion system ( SPS ) engine was originally designed to lift the CSM off the surface of the Moon in the direct ascent mission mode, [ 20 ] The engine selected was the AJ10-137 , [ 21 ] which used Aerozine 50 as fuel and ...
Apollo 7 did not carry a Lunar Module. A structural stiffener is used to provide sufficient stiffness of the SLA. On all flights through Apollo 7, the SLA panels remained hinged to the S-IVB and opened to a 45-degree angle, as originally designed. But as the Apollo 7 crew practiced rendezvous with the S-IVB/SLA containing a dummy docking target ...
Each Moon flight carried two AGCs, one each in the command module and the Apollo Lunar Module, with the exception of Apollo 7 which was an Earth orbit mission and Apollo 8 which did not need a lunar module for its lunar orbit mission. The AGC in the command module was the center of its guidance, navigation and control (GNC) system.
Launch of AS-506 space vehicle on July 16, 1969, at pad 39A for mission Apollo 11 to land the first men on the Moon. The Apollo program was a United States human spaceflight program carried out from 1961 to 1972 by the National Aeronautics and Space Administration (NASA), which landed the first astronauts on the Moon.

The Apollo 17 lunar lander module left behind by US astronauts on the moon’s surface could be causing moonquakes, or small tremors, a new study revealed.
Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.
