Just read some info on the Apollo 10 mission that I thought was interesting. (Or maybe I'm just bored tonight.) Instead of impacting the moon like the other LMs that went to the moon, the A-10 LM, nicknamed "Snoopy", was sent into solar orbit. Kinda neat to think that there is still one LM still out there flying around. Maybe like a lost dog it will wander home some day. :D

Since there were no seismic stations on the moon, there was no reason to crash it into the surface as they did for most of the later landing missions. They wanted to test the ascent stage engine by burning the fuel to completion, so they fired it off into solar orbit after the crew was finished with it. It should still be out there, but it was not tracked long enough to have any chance of intentionally finding it 30+ years later.

Did you hear about the Apollo 12 S-IVB stage that was rediscovered a year or so ago and was actually back in high Earth orbit after more than 30 years in solar orbit? It was recognized by its spectrum which was similar to the Titanium Oxide paint it is covered in.

I hope some day we can recover a few of these long lost artifacts so that we can put them in a space museum.

From what I understand the Apollo 12, 3rd. stage orbited the Earth for about 1 year, and then was "flung" back out in to space again.

Apollo 12 3rd stage = Object neocp j002e3

It left earth orbit out through L1 back in may- pretty cool while it lasted though!

From what I unnderstand about the A-12 booster, it is in an orbit that will bring it back to Earth orbit every so often. How long they expect the orbit to remain stable is unknown.

How do you fire the ascent stage with no one on board? Was there a capability to control the LM remotely?

Oh and also, how hard did the other LMs hit the moon? Is there a noticable crater? That would be really neat. 8)

The onboard computer flew the LM to its preprogramed impact point. I'm sure they left craters, but I've never seen a picture of one attributed to the LM. I have seen a picture of a crater caused by the impact of the Apollo 3rd stage. I can't remember where I saw it, but I'm sure someone on this board can probably provide a link.

Are talking about an S-IVB booster impact on the moon? *I'd* like to see that as well.

Yeah, the S-IVB, couldn't remember the official term that they used for it.

Check out the Apollo 16 Preliminary Science report which contains a pair of papers, one by Ewen Whitaker and I forget the second authors name which discuss impact craters caused by manmade objects. Specifically the S-IVB stages and a Ranger spacecraft. There are some images of some of the craters. I don't think anyone ever identified a LM ascent stage crater in photographs, though Ron Evans on Apollo 17 thought he had ID'd the impact crater on the South Massif caused by the Apollo 17 LM ascent stage.

Just curious - is there a site where the de-classified man made objects can be viewed and tracked? I would love to know how many we've put up and have NOT lost.

This may not be exactly what you're looking for: www.heavens-above.com

After registering, see under the Satellites heading, where it reads: "Daily predictions for all satellites brighter than..." - they list some Russian and US rocket stages that defunct satellites that are still in orbit.

Everything you want to know about the LM ascent stage impacts can be found here:

http://history.nasa.gov/SP-4029/Apollo_18-29_LM_Lunar_Impact.htm

The estimated crater sizes were around 10 metres (30 feet).

I've got to say it's highly suspicious that the page you refer to seems to mention Apollos 18 to 29 in the address:

http://history.nasa.gov/SP-4029/Apollo_18-29_LM_Lunar_Impact.htm

Obviously there were other missions we weren't told about, but for some whistleblower! :o
