I then turned to the ascent stage of the Apollo 11 Eagle...no one knows what became of that little piece of history either. And again, amazingly, the simulated orbit shows a long-term stability very similar to that of the Snoopy stage. Wow! That was in September of 2020, and you might notice that the blog posts stopped around that time. Instead, I focused on writing up the results for peer review and publication, and after some fits and starts I am proud to say that the paper is published.
My intent now is to expand on the Eagle results and continue looking for other interesting objects from that era.
You can page through the blog posts in order for a "tutorial" on the process I went through. Or skip around to whatever looks interesting.
Love it? Hate it? Don't believe it? Post your (respectful) comments.
Hope you enjoy the material!
I just finished reading the whole thing here, very interesting! Have you considered running your same analysis with the subsatellites that were launched by Apollos 15-17? They are all known to have crashed. Does GMAT predict their crash?ReplyDelete
Also, does your model include small forces like solar radiation pressure?
Thank you. I definitely included solar radiation pressure, and the gravity effects of other planets.Delete
I have done some modeling for the Apollo 16 LM "Orion" and I find that it probably struck the surface around the same time as the subsatellite, late in May of 1972. (Orion and the satellite were in very similar orbits.) I hope to have more to say about it at some point.
Check out the new post on the Apollo 16 subsatellite called "Reality Check". GMAT does a pretty good job to match the date of impact.Delete
My dad (who passed away in 2017) was the Chief Test Director of the second stage of the Saturn V. I think this is awesome and I truly hope you see the ultimate fruits of your labor - either confirmation of the still-orbiting spacecraft, or a definitive crash site.ReplyDelete
Thanks GL. There is definitely more interest now that the Eagle paper passed peer review and was published.Delete
Well, THAT's embarrassing! I just figured out that there were several comments waiting for moderation. Didn't have the right plumbing to be notified about them. Sorry about that folks!ReplyDelete
