In the Manned Spacecraft Operations Building, engineers and workers mated the Ascent and Descent Stages of the Apollo 10 Lunar Module (LM-10) Snoopy. This was in preparation for altitude tests in January 1969.

"APOLLO SEPARATION - ART CONCEPTS

A North American Rockwell Corporation artist's concept depicting the Apollo 10 Lunar Module descending to 50,000 feet for a close look at a lunar landing site. The Command and Service Modules remain in lunar orbit. The landing area is Site 2 on the east central part of the moon in southwestern Sea of Tranquility (Mare Tranquillitatis). The site is about 62 miles east of the rim of the crater Sabine and 118 miles west-southwest of the crater Maskelyne. Apollo 11 is scheduled to be the first lunar landing mission."

Date: April 1969

"LUNAR LANDING - ART CONCEPT

Artist's concept depicting the firing of the Apollo 10 Lunar Module descent engine for 42 seconds to propel 'Snoopy' back into a higher lunar orbit for rendezvous and docking with the Command and Service Modules. Earlier, the LM descent engine will be fired for 27 seconds to take astronauts Thomas P. Stafford, Apollo 10 commander; and Eugene A. Cernan, lunar module pilot, to within 10 miles of the moon's surface. Astronauts John W. Young, command module pilot, will remain in the Command Module, 'Charlie Brown,' in lunar orbit. Developed by TRW's Systems Group at Redondo Beach, California, under Grumman subcontract, the throttleable descent engine will be used to soft land the LM on the lunar surface during Apollo 11 and subsequent Apollo missions."

"Apollo 10 rollout from the Vehicle Assembly Building (VAB) to Launch Complex 39B. This mission launched on May 18, 1969. The crew of Tom Stafford, Gene Cernan and John Young flew the 'dress rehearsal' for the first human landing on the Moon."

The Grumman Aerospace Corporation was awarded the contract on November 7, 1962. Originally designated Lunar Excursion Module (LEM), NASA ordered 25 lunar modules (10 test articles and 15 production models) for testing and landing on the moon. This was to go with the 15 Saturn Vs and Apollo CSMs. They were assembled in Grumman's factory in Bethpage, New York.

"There were initially four major subcontractors: Bell Aerosystems (ascent engine), Hamilton Standard (environmental control systems), Marquardt (reaction control system) and Rocketdyne (descent engine).

The Primary Guidance, Navigation and Control System (PGNCS) was developed by the MIT Instrumentation Laboratory; the Apollo Guidance Computer was manufactured by Raytheon (a similar guidance system was used in the command module). A backup navigation tool, the Abort Guidance System (AGS), was developed by TRW."

After the Gemini 3 spacecraft was dubbed Molly Brown by Gus Grissom, NASA forbade naming spacecraft. For Apollo 9, this changed due to mission controllers in Houston needing a way to differentiate between the two spacecraft.

Between 1969 and 1972, Grumman produced a series of insignias for their Lunar Modules which were distributed in limited quantities to their employees in the form of decals and prints.

Apollo 5 (LM-1): none

Apollo 3 (and later 2) (LM-2): Never used, intended for a mission similar to Apollo 5. The success of LM-1 led to the cancellation.

Apollo 9 (LM-3): Spider

Apollo 10 (LM-4): Snoopy. The LM ascent stage in heliocentric orbit and is the only known one to have survived intact

Apollo 11 (LM-5): Eagle (originally named haystack)

Apollo 12 (LM-6): Intrepid

Apollo 13 (LM-7): Aquarius

Humorously, Grumman sent North American (the manufacturer of the Apollo Command and Service Module) a tow bill sometime after the crew returned. North American retorted back saying they've never sent them a tow bill for the previous missions.

Apollo 14 (LM-8): Antares.

Apollo 15 (originally) (LM-9): never used, on display the Kennedy Space Center.

Intended for Apollo 15 and was the last H-type mission. When Apollo 18 was cancelled, it was decided to make Apollo 15 the first J-type mission.

Apollo 15 (LM-10): Falcon, originally intended for Apollo 16. First of the extended stay series.

Apollo 16 (LM-11): Orion, originally intended for Apollo 17

Apollo 17 (LM-12): Challenger, originally intended for Apollo 18.

Note: this name was reused for the second operational Space Shuttle Orbiter. After the Challenger Disaster, NASA officially retired the name.

Apollo 18 (LM-13): never used, originally intended for 19. It was partially completed when Apollo 18 and 19 were cancelled. Later restored by Grumman workers and is on display at the Cradle of Aviation History and Education Center.

Apollo 19 (LM-14): never used, originally intended for Apollo 20. It was partially completed when Apollo 18 and 19 were cancelled. What was completed, was later scrapped.

Apollo 20 (LM-15): never used, partially completed, scrapped. When Apollo 20 was cancelled, it was intended for modification into the Apollo Telescope Mount. Later the Telescope Mount was integrated into Skylab and this dedicated mission was cancelled.
