... Apollo 10’s lunar module… Posts: 1624 From: Bethpage, N.Y. The spacecraft mass of 15103 kg was the total mass of the LM ascent and descent stages including propellants (fuel and oxidizer). From the Apollo Flight Journal and the Apollo Lunar Surface Journal, this is the best annotated Apollo 11 descent footage I’ve seen yet. If the Apollo 11 Lunar Module ascent engine failed, what would NASA have done? Template:Infobox spacecraft class. The Apollo 11 lunar module Eagle is seen from the Columbia command module in this photograph by command module pilot Michael Collins on July 20, 1969.
One revolution later, a test of the RCS drawing propellants from the ascent engine tanks would be performed and a second burn of 7.5 minutes in duration would position LM-1 into an orbit of 506 x 196 miles (815 x 315 km). Registered: Jul 2002: posted 04-28-2011 10:18 AM Approximately how long would the consumables last if the Apollo lunar module's ascent engine failed to ignite? The dry mass of the ascent stage was 2445 kg and it held 2376 kg of propellant.
LM-1’s ascent engine would burn for 5.25 seconds, pushing the upper part of the lunar module into a slightly lower orbit. On schedule, the LM’s ascent engine fired. SpaceAholic Member .

If the Apollo 11 ascent engine failed to ignite on the moon during liftoff could Neil and Buzz gone outside to try and fix it?
You’ll want to watch this full-screen. There was a good amount of exhaust blowback during lunar liftoff, hence the dozens of bits of shielding you see flying off the descent stage in the Apollo 15, 16, and 17 lunar liftoff videos – most of which was from right under the ascent engine – and the damage sustained on the rear of Orion‘s ascent stage during Apollo 16. But, Barry says, the command module couldn’t solve the problem if the lunar module wasn’t able to get off the surface.
The descent propulsion system (DPS - pronounced 'dips') or lunar module descent engine (LMDE) is a variable-throttle hypergolic rocket engine invented by Gerard W. Elverum Jr. and developed by Space Technology Laboratories (TRW) for use in the Apollo Lunar Module descent stage. No. I heard from a documentary that "the ascent engine failed on the six times it was tested in space on at least three of those occasions to some degree or other, so there was a 50/50 chance that that engine would work exactly as planned". The Eagle has Landed - Revell 1/48 Lunar Module Post by Tomcat64 » Tue Oct 10, 2017 10:31 am My entry into this SiG will be the Apollo Lunar Module from Revell - the shot above is the Apollo 11 Lunar module "Eagle" as seen from the Command Module "Columbia" prior to the lunar … ... Command Module Pilot John Young waiting in the Command-Service module. Topic: Apollo lunar module: Ascent engine failure: SpaceAholic Member . The Apollo Lunar Module (LM), originally designated the Lunar Excursion Module (LEM), was the lander portion of the Apollo spacecraft built for the US Apollo program by Grumman Aircraft to carry a crew of two from lunar orbit to the surface and back. But the practice run came close to failure. This topic is 2 pages long: 1 2 .
