Is Apollo 11's Lunar Module Still In Orbit Around The Moon 52 Years Later?

In 1969 Neil Armstrong announced a safe touchdown on the moon with the words 'The Eagle has Landed'. "Eagle" was the name of the Lunar Module, the spacecraft which carried Neil and Buzz to the surface of the moon. After they walked on the surface of the moon they flew the Eagle back into orbit, docked with the Columbia command module and undocked the Eagle, leaving it in orbit while Columbia returned to Earth.
Most spacecraft in lunar orbit suffer from instability in their orbits due to the 'lumpy' nature of the lunar gravity which tends to cause the orbits to eventually get so elliptical that they hit the moon.
However, an amateur space fan wanted to narrow down the possible impact location and used orbit modelling software to propagate the orbit forwards in time until it hit the moon. He was surprised to find that it didn't hit the moon, and remained in a stable orbit for decades, this suggests that the Eagle may still be orbiting the moon over 5 decades after being left there.

If Eagle is still orbiting, it would be a worthy mission to go link up with it and check out the material condition. When Columbia jettisoned it, it was holding cabin pressure.

However, even if retrieved, which in itself would be a fantastic, probably somewhat dangerous feat, but probably feasible, there would be no reasonable way to return it to Earth. It has ability to survive anything but space itself. Still, it could be captured in lunar orbit and examined there, including a visit, or at least remotely controlled cam and sensors. I doubt it would be worth the risk of sending someone back into it. Not that much to learn that remote methods couldn't provide, and some potentially very high risk possibilities in what is effectively an almost unknown craft now that it's been up there for 50 years.

Although it would be one of those "one in a million" scenarios, it is also possible that small or even micro meteors would have impacted the ascent stage during the past 50 years, imparting unknown forces on the stage at some random angle/vector... Making the orbit even harder to model. Still though this is a very good hypothesis and I think it is worth follow up

And the interior atmosphere lost would add a wee bit of thrust as well.

[@geekswithfeet9137]

Those effects are probably still with in the distribution of those simulated as an error in initial conditions.

[@mikenccc1955]

Why 'one in a million' ? each ascent stage came up to orbit to dock with the CSM and let the astronauts get back into the command module. Then detached and (presumably) the CSM just used orientation thrusters to back gently away.... no particular reason then to crash the ascent stages, so I don't see why all six should not still be there ( 11,12,14,15,16,17 ). All went down - all came back up.

@Ronnie Lee Excellent question (about the accent). Excellent answer: the camera was mounted on the landing craft and set to run as the module blasted off: NASA didn't call on Moon-dwellers to perform camera duties. They simply mounted a camera on the Descent Stage of the Lunar Module and pointed it at the steps. That giant leap was relayed live to NASA and TV viewers all over the world via receiving stations on Earth.

At the end of the missions, the rovers were placed at a suitable distance from each of the landing sites so that the camera (remotely controlled from earth) could film the lunar ascent back into the moon's orbit to re-dock with the command module.

The only reason I joined the Math Club was to learn to write, run and play with simple programs. We came across Lunar Lander and down loaded it. To run even the most basic programs we had to connect long-distance over the phone (modem) to a UNIVAC mainframe at the university 90 miles away. We were restricted to after-hours and a certain number of hours per week due to cost to the school. Somehow one of the students figured how to bypass the password system, and we got unlimited use. It was so much fun! There were no graphics capabilities, only data inputs and outputs (initial speed and altitude, retrorocket burn rate and time, and remaining fuel. We mostly created a lot of new craters!) A year or two later I took a summer course for HS students at the local university to learn FORTRAN programming (with teletype punch cards and reams of paper). My study group chose a final project to write a program for Battleship, and print out the moves on a giant plotter. Such technological advancements!

History

[@ianc4901]

It's one thing to send an empty vessel to recover it but it's something very different to return it intact. It was only ever intended to be a single purpose vehicle so no provision was ever made to it in order to recapture it. There is no easy way to grab hold of it, nothing to fasten to and no base for it to sit on when it's being returned. It would be severely damaged by gravity, restraining and handling because it wasn't designed to be recaptured and retuned.

I talked with a NASA trajectory expert, and the heading at 7:10 is correct. It was based on the Earth's pole, and not the Moon's. Seems odd to show it in that frame of reference, but must have added some value at the time. (I assume related to the return orbit or re-entry to Earth, or maybe the near -90 had to little value.) The "expert" appreciated your link to the Meador paper, as he had not seen that yet.

[@jimmeador5276]

Yes, initially I thought that must be the source of the error. But when you plug in that value from the mission report and shift to Earth-centric coordinates, it still doesn't come out right. So in the paper I state that the value is wrong "for unknown reasons". Remember that those Mission Reports were typed by hand, and someone was probably transcribing numbers from line printer output. Perhaps they copied a value from the wrong part of the table?
