Holy schmoly. That really drives home the amount of labor-intensive planning these orbiters do ahead of time. We want to take photos of these 6,494 places. Sheesh. Sometimes 5000 just won't do. Sorting the spreadsheet by column E 'human artifacts' is fun. Looks like they're depending on some Stooke fellow for the Luna and Lunokhod locations.

on the contrary, looking forward to the extreme closeup images of the lunar surface with a spatial resolution of 0.5 meters per pixel over 5 kilometers wide swathes. Wishing You had these available for the International Atlas of Lunar Exploration to show the Ranger impact sites and Surveyor, Luna,... hardware left there in the 1960s and 1970s.

Nonsense.




Everybody knows the monolith is in fact located near Tycho.

There is a moon crater Clavius, plus a fictional base named Clavius.

Now, seriously, I really like LRO to find out the location of the old Soviet probes - Luna 9, for example..

Me too, but that and Luna 13 will be extremely difficult.

I've read that it will take a couple of months to fine tune the orbit.

How soon after that can we expect some high resolution pictures of an Apollo landing site?

(I realize that the scientific value isn't so high; I'm just eager to see them.)

I read somewhere they will be trying to capture an image of the Apollo 11 landing site in time for the 40th anniversary.

According to http://lroc.sese.asu.edu/whereislro/ LRO is currently traversing longitude 71E and 109W in its orbit. Since its longitude moves westward about one degree every two-hour orbit, it should fly pretty close to the Apollo 11 landing site (at 23E) in about 71 - 23 = 48 orbits or about 4 days. Could it happen? smile.gif

Hmmm... let me think... 40th anniversary coming up... Constellation floundering... public support for a "Return To The Moon" sorely lacking... conspiracy theorists insisting we never went to the Moon in the first place... a science-friendly but budget-reviewing new President to impress....

I'm guessing "yes". laugh.gif

I'm guessing that even if it's taken, it won't be released until the actual anniversary date, probably on the day of the landing. Maximum PR impact etc.

I wonder what the PR impact of such an image would be though, outside the enthusiast ranks. What would it show? At 50cm/pixel at best (and probably more like 1m/pixel) it's not like much detail on the LEM platform (diameter 5m) or whatever would be resolved, right? People might say, "where are the footprints?"

Maybe Apollo 17 would be of more photographic interest? Since the rover traveled around quite a bit (35km total traverse), is it possible that its tracks would show up on the photo as discernible lines? It's at longitude 31E which should come up a bit quicker, this Saturday.

MRO didn't show much detail on the rovers and Phoenix either, but it was a large PR impact for those of us who did care. The rest of the folks couldn't care less anyway. I expect the same with LRO images. What will be visible depends on solar elevation, lower elevation would benefit contrast between hardware and surface and give longer shadows, but mostly albedo markings like footprints would benefit from a lower phase angle. Yes, the Apollo 11 site isn't the best candidate, but given the approaching anniversary it would be a fitting way to mark the event by imaging it first. The rest of the sites can wait for their anniversaries laugh.gif

I don't care how vague or fuzzy or blurry the images are when they appear, they'll still be very moving, I'm sure. I remember how I felt when I saw that first MRO shot of Oppy on the edge of Victoria Crater, I actually didn't say a word for about five minutes, I just sat there thinking "Wow... we built that and sent it to Mars, where it was photographed by something else we built and sent to Mars..."

(BTW, I'm mega-chuffed that Phil Plait has just plugged my 'LRO vs Apollo Hoaxers' blog post on his "Bad Astronomy" blog. biggrin.gif )

Oh boy, this mission is so exciting. Can't wait for those images of Apollo hardware and other stuff on the surface. Hopefully they'll take some snaps of the Apollo 17 ascent stage impact site on the South Massif too.
