Chris... your model looks like a photo!

Fenerit, discussion is never distraction, IMO, because if one replies and enters the discussion, obviously the subject interests him, so it's not a waste of time. :wink:

Grazie, ciao. (Thank you, bye.)

That's the goal... (even without using textures and without shadows!) :wink:

Yes ElChristou, your model is marvelous! The detail!

As for the moon missions, do people really doubt it ever happened? Where is the proof it actually happened? How about the laser reflector experiments? If you had the proper equipment, you could verify it yourself.

Apollo Laser Ranging Experiments Yield Results - NASA

Lunar laser ranging experiment - Wiki (also providing several additional references)

Nice picture of the laser reflector placed by the Apollo 14 mission. - NASA

What more proof do people need?

Well, going back to our topic, I would like to show you the aerodynamics needed for non-atmospheric flights.
Surely you have seen the clean, sharp, smooth, glossy, flattened appearance of objects that need to move within the Earth atmosphere, like this image of an Jupiter-C nose cone:

But when all the movements happen in space, all this is uselessly time/effort/money consuming.
So, if we give a close look at the LEM, that never tasted the atmospheric effects, here are the results:

As you see it has a crunched, grimy, rough appearance, like something unfinished, giving more the idea of cardboard instead of metal (I can imagine the comments of keen on Moon-Hoag people! :wink:

).
But this is the engineering rule: "never add what you don't need and you don?€™t care of", and in space there is no friction that, in order to reduce the drag, should need the smoothest possible surfaces, so?€¦
Enjoy!
Bye

Yes, there is some shots of Apollo 16 AS after take off from the moon and really it looks like a giant piece of trash!!

Edit:

Here:

I particulary like the cables that have been strip off from the DS (red arrow)... Also the back panels completely blasted out by the take off...

Unfortunatly I don't think I'll do a model like this because it would be far too arbitrary (there is no close up to see exactly want is visible behind those deformed panels)...

Alas, it's unfortunately true. :cry:

Chris, looking around as usual, I found something more, related to the Apollo 11 landing ground.
Three photographs and one very detailed drawing, showing the landing site at various resolution, and the experiments positions on the ground, together with the astronauts walks, and more. :wink:

Hope this will give you a further help to realize the 3D ground.

(this is only a small portion of the original image)

You can find all four image in the zipped file here:

I'd posted this for all of you, to try and help the effort, to save you some time searching around. Please do check this link out, I think you'll be pleased at what you find...

Yes, I found some interesting point of view for the modelling. Don't worry, with time all those links will be browsed!

Post edited - I noticed right after posting that Andrea had gotten those images from that source... silly me. :oops:

Andrea, concerning the ground, we will do that with Runar a bit later; right now for example I'm stucked on the LRRR; I have tryied to find myself something, but couldn't, what I need is what is not visible in this view (particularly the articulation):

OK, I'll check for some new images of the LRRR.
Bye soon (I hope).

Chris, it's late here, 1:40 AM, so I had just a little time to search for LRRR images before going to sleep.
I found just a few, like these:

You can find all of them here
http://nho.ohn.free.fr/celestia/Andrea/LRRR-NEW.rar
Tomorrow I'll search more, but obviously the search is open for ALL Celestians, this IS NOT a one guy's job, but a cooperative effort, as has been up to now, with many precious additions to my search. :wink:

Thank you.
Bye

You are welcome.
And as my today's last try, here two new ones:

If you need you can download them, are 1/1 copies of the originals, with only the quality reduced to 7/12.
Unfortunately the second one is out of focus, due to its distance from the astronaut (Aldrin). :cry:

Nighty night!

ANDREA · Post #178by **ANDREA** » 01.06.2007, 10:16

This is the last one, I think.
It's the "official" Apollo 11 LRRR drawing, and this is important, because we have seen some differencies in the given images, even if all reported as "Apollo 11" LRRR.

You can download the full-res image here:

BTW, Chris, the image of your model is IMHO perfect, at least from the shown point of view!

Not really, I think the boom attachment was removed at some point, I suppose it have it's reason for stowing...

BTW, if you see anything else for the seismometer, you know what to do... :wink:

Sure, but it was probably removed AFTER the final alignment, because no more needed, but as you see in the second image of my post on Fri Jun 01, 2007 1:35 am, it was there while the seismometer was still under installation.
I have found any witten documentation about boom removal, anyway, I'll search a bit more.

OK, I'm going to dig the web, anyone else lining up at the starting tape? :wink:
