Great question! Science. The Lander, also known as the Lunar Module (LM), was a two-stage craft built to separate from the Apollo Command and Service Module, and then travel to and from the moon’s surface. Credit: NASA. The Apollo lunar module landing-gear flight-performance results and three prin­ cipal gear development problems are discussed in this report. By Amy Shira Teitel. If not deployed, the landing gear would be in the path of the descent engine plume and would be damaged. The Apollo Lunar Module (LM), built by the Grumman Corporation in Bethpage, NY, was the vehicle that would take two astronauts down to the lunar surface and return them to the waiting Command Module in lunar … The upper ascent stage consisted of a pressurized crew compartment, equipment areas, and an ascent rocket engine.

Inside the "Spider" were astronauts James A. McDivitt, Apollo 9 commander, and Russell L. Schweickart, lunar module pilot. Seeing Inside The Apollo Lunar Module. According to LMA790-3-LM Apollo Operations Handbook: Lunar Module LM 10 and Subsequent Volume I, section 2.3.6:.

Once the contact probes touched the lunar surface, the descent propulsion system engine would be shut off, and the LM would drop the remaining distance to the ground.

December 16, 2013. Landing gear extending … Astronaut Buzz Aldrin stands next to the landing gear of the lunar module built in Montreal. $\endgroup$ – Organic Marble Mar 17 at 13:01 $\begingroup$ To be clear, do they have the AGS but not the primary, or are both computers down? Latest. $\endgroup$ – Uwe Mar 17 at 12:53 $\begingroup$ @Uwe great comment, thanks, will add. The landing gear on the "Spider" has been deployed. The first manned lunar landing occurred on July 20, 1969 with the Apollo 11 LM Eagle.Four days later, the Apollo 11 crew in the Command Module "Columbia" splashed down in the Pacific Ocean, completing President John F. Kennedy's goal of "landing a man on the Moon and returning him safely to the Earth." The landing gear were folded for launch and deployed later in the mission. The four landing gear system "legs" (or "struts") on the Apollo Lunar Module descent stages were indeed built by a Canadian company called Heroux-Devtek, based in Quebec. It first landed on the moon on 20 July 1969. The Apollo Lunar Module (LM) was a two-stage vehicle designed by Grumman to ferry two astronauts from lunar orbit to the lunar surface and back. These landing legs were constructed of a light-weight aluminum and compressible honeycomb design to aid in shock absorption. The model of the Apollo Lunar Module consists of the Descent Stage and the Ascent Stage. As a former mechanical engineer who is passionate about space exploration and everything to do with Project Apollo, I’d LOVE to answer it. The landing gear development included extensive tests of the aluminum honeycomb energy absorbers and the double-cylinder strut bearings to make sure they could handle the weight and stress of landing, according to NASA. More Vintage Space. The landing gear must be deployed before descent engine firing. A fixed outrigger assembly formed the top of each landing gear assembly. Lunar Module Descent Stage Landing Gear. Lunar Module Landing Gear Strut Crushable Honeycomb The lunar module needed some sort of shock absorber to cushion the impact of landing on the moon. $\endgroup$ – Russell Borogove Mar 17 at 17:01 In evaluating the lunar module touchdown performance, strut stroking and toppling stability are the prime factors and are governed primarily by touchdown velocity and surface slope at the touch­ down point. The landing gear was specifief for less than 4 foot per second. Lunar surface probes (sensors) extend out from landing gear foot pads. If they choose (more/less) 1:1, they had to propose landing gear 60/70 (or 90) feet wide. Four landing gear assemblies were attached to the descent stage.

The Apollo 11 Lunar Module Eagle in lunar orbit. Apollo service module was 13 feet in diameter. In addition, the model includes the Lunar Roving Vehicle, various equipment such as the ALSEP (Apollo Lunar Surface Experiments Package) and a display stand.
