Hunchbacked makes many claims as to his expertise. Suddenly he thinks that he is an expert about orbital mechanics. Hunchbacked postulates that the only safe way a LM can descend and land on the moon, after separating from the CSM at an orbital altitude of approximately 60 nautical miles, is to continuously fire the LM's descent engine and follow a parabolic trajectory from orbit all the way down to the lunar surface. This video shows how LM landings were actually done and why the chosen method was the safest.

  • I don't understand the maths in the slightest, I have no engineering training or experience, but even I can see the elegance of DOI.

    Speaking of elegance, the music is very pleasant and soothing. Reminds me of some parts of Myst.

    Is it yours, and if so is it available for download?

  • @loperspest I forgot what music I used for this video. Either it was from freeplaymusic or I picked something from YouTube's free music. If it was from freeplaymusic then it most likely was a piece by Kevin MacLeod as he is one of my favorite artists featured on that web site.

  • @hunchbacked So now that I have explained why the CSM and LM orbited the moon in a retrograde orbit, your assertion that the increase in the horizontal speed of the LM relative to the moon's surface due to the moon's rotational period is also ludicrous since the moon's equatorial rotational speed is only 10.3 miles per hour. Perhaps 10.3 miles per hour is a much too dangerous velocity over there in France? Hunchbacked, I will say it again. You are an idiot.

  • @BlisterHiker I keep thinking of Raul Julia's character in The Great Gumball Rally. He rips the rearview mirror out of his car and tosses it away saying "What's behind me is not important" In hunchbacked's case, whatever he doesn't understand is not important. Nor can it work.

    One of his current videos claims that the LM's A/D converter couldn't work. Problem is, he only knows one A/D method and the LM didn't use it. The text gave the actual method but he didn't bother reading it.

  • "the computer computes the moment the LEM must be ejected from the LCM" What??? And then what, Hunch? The LM immediately starts descending towards the Moon because it was "ejected" and is no longer attached to the orbiting CSM, like a sky diver falls towards the Earth because he jumped out of an airplane? You have a completely ridiculous understanding of orbital mechanics.

  • @GoneToPlaid

    Oh yes. One of my favourite Lets Play used "Funkorama" by the same for its end credits.

    I like it so much I downloaded it from his website.

  • @hunchbacked Once again, you are an absolutely marvelous demonstration of how, in the wrong hands, a little knowledge can be incredibly dangerous. The significant advantages of the retrograde lunar orbit have been explained to you several times. But you can't or won't understand them, so you dismiss them as unimportant compared to a difference of a few meters/sec in lunar surface velocity. Absolutely amazing.

  • @hunchbacked Obviously you don't have the brains to do the basic math.

  • @GoneToPlaid

    Yes, as written in the Apollo documentation by engineers who had the sense of humor!

  • @hunchbacked A normal versus retrograde orbit would lengthen the time required not only to fly to the moon, but the time required for a free return to earth. And a normal orbit provides no opportunity for an alternative maneuver to orbit the moon and return to earth. Targeting for a retrograde orbit provides for this capability. If the TLI burn was not quite enough for the preferred retrograde orbit with free return, then one can target for a "normal" orbit with a free return.

  • @mercatormac

    It would have changed nothing to the return.

    It would also have made the return a little easier.
