I can't believe they continue to publicly display their ignorance. I would be embarrassed to be associated with them. Well, on the positive side, it is only YouTube... those f***tards have managed to get themselves banned from pretty much everywhere else. And at least there, people can actually see them for the moronic idiots they really are as they continue to display their fundamental lack of intelligence and over-reliance on insults and bullying.

Yes, they've turned YouTube into a zoo...and they're monkeys flinging their feces at the passerby.

...final science orbit for the LRO is ~35km x 65km, so at that altitude, the resolution would definitely improve. I thought it was just going to be in a circular 50km orbit, but this is better. Where did you hear/read this? lunar.gsfc.nasa.gov/mission.htmlfound this on the LRO Camera site

Why are the footpaths so prominent in the Apollo 14 image? Could the tracks have been made by the equipment transporter going back and forth? AS14-68-9405 It looks like it would have made some significant tracks.

Just wanted to say how much I loved seeing these images and Rodionh's work in providing a reference. Just wondering how much better the images will be in naked eye terms when the LRO reaches it final orbit? I've read figures for the resolution but I'm just trying to picture it, something close to Rodionh's third image maybe?

Excellent, it won't shut up the hardcore but it might help those who are just confused by all the HB spin.

AS14-68-9405 It looks like it would have made some significant tracks. AS14-67-9367 is a good up-sun view which shows the tracks. It's part of a panorama, so others around it may be worth a look. Note Al Shepard's footprints leading offscreen at centre right. ALSJ caption: This up-Sun photo was taken from near the ALSEP Central Station back toward the LM in order to provide relative location information. As with the astronauts' bootprints, the track made by the MET tires are compact, smooth, and, as can be seen so dramatically in this picture, more highly reflective than the rough undisturbed surface. Journal entry.That particular photo is the one we used at BAUT nearly five years ago to figure out exactly where the flag is. The online scans of the time didn't help much, but a book did. Can you believe that, solving a problem with such ancient technology?

A friend of mine argued about the shape of the shadows, and this is what I told him. First, these are "late lunar afternoon shots", and thus the shadows are cast towards the east, rather than the west (as they were during the day of the landings). And the fact that it's late afternoon, means that the shadows are long. My friend still couldn't believe that was a descent stage shadow. Then I asked him, "So how is it supposed to look like?" and he said "I dunno, how is it supposed to look like?" Then I told him this... "If I can show to you a simulation of the descent stage casting a long eastward shadow on the surface, and you compared the shapes of the shadows, and found out they match, would you then believe me?" And he said "Yes." So here's what I did... I first took a snapshot of a simulated descent stage (quite well detailed 3D model) sitting on the lunar surface at Tranquility Base (exact coordinates, with simulated landmarks as well). img.photobucket.com/albums/v291/rodsky/orbiter/descent_stage_001.jpgThen, I pulled out a bit and took another snapshot, and explained to him the shape of the shadow... img.photobucket.com/albums/v291/rodsky/orbiter/descent_stage_002.jpgThere are two "horns" on the shadow, created by the RCS thruster deflector mounts. Why am I emphasizing this? Because, when I pull out further... img.photobucket.com/albums/v291/rodsky/orbiter/descent_stage_003-1.jpg...and view the site from directly above, you can actually see those two horns at the eastern end of the long shadow. Now compare the above image with this: www.nasa.gov/images/content/369234main_lroc_apollo11labeled_256x256.jpgI then said to my friend, "Now compare the shadows...pretty close huh." And he was dumbstruck. -RODION Here is an animated image where your picture blends into the Apollo picture, for comparison. It's not perfect, but it's something, I guess. (I dunno if it has been done before, but if not, here you go.) The picture is a bit big in terms of filesize.

Incidentally, your picture is also a good example of crosshairs being washed out by bright objects - take a look at the LM: there's a bright spot that partially washes out the crosshair at one point.

Why are the footpaths so prominent in the Apollo 14 image? NASA says there was a "desirable lighting condition" for the image, and I know from a Clavius page that compressed regolith can be very reflective, does that have anything to do with it? Another possible reason, or at least one that contributes to the footpath being visible - Alan Shepard and Ed Mitchell used a new device for hauling materials - the MET (Modularized Equipment Transport) or what they called it, the Lunar Rickshaw. Their second walk was the first full "geology field day". On their walk to Cone crater, the MET got loaded up but pulling it was almost impossible because the dust at Frau Mauro was thicker and deeper than at previous landing sites. The astronauts ended up carrying the MET a lot. They never made it to Cone crater because of so much dust. They were ankle deep in it. Shepard said, " You take two steps up and you slip back one. It's like a day at the beach plodding through deep sand," I would imagine plowing through that would create more of a visible path for the LRO to see. EDIT: just read trebor's comment Could the tracks have been made by the equipment transporter going back and forth?AS14-68-9405 It looks like it would have made some significant tracks. I've been away camping for three days so I haven't caught up on all the new postings...

Alrighty. A mighty huge thanks to drewid pointing me to this thread and the software. I am downloading it now so that I can play with it and hopefully set up a recreation of the reflected view in Aldrin's visor from image AS11-40-5903 since that is the one photo which I have really sunk my teeth into at the moment.

Rodion
Thanks for the images and the links, im really enjoying the simulator.
On the subject of the LRO I had not realized that these images were taken at about 230km above the moon. The LRO is due to move to a much lower polar to polar orbit of 30km, could we be in store form some more awesome photos?.

Definitely. We haven't even begun to see just how good the LRO photos will become.

The landing stage will be 20-30 pixels across, and the rovers and some of the bigger experiments should be visible. EXCITED? ME?
