It looks as though the Surveyor 1 site has been imaged. The image was taken when the LRO was still in the commissioning orbit. http://lroc.sese.asu.edu/news/?archives/11...ar-landing.html Old http://www.unmannedspaceflight.com/index.p...st&p=147019 Anyway, good contribution |

Not a "bad" at all, don't worry about it JRA, it happens all the time When I joined here I lost count of the number of times I alerted the board to something already mentioned by someone else.
I prefer to think of it as "being keen to share", not "old". -------------------- |

I noticed some funny-looking craters on LRO's image of the Surveyor 1 landing site. Below is a sampling.
These three craters are all at the same scale. They seem recent and are around 100 m wide or less. It looks like the unconsolidated regolith was pushed back by the blast produced by the impact, revealing the surface of the bedrock. If this interpretation is correct., these craters would make great sampling spots. No need to dig through the regolith to get to the bedrock, the work has already been done by meteorites. |

Surveyor 1 happened to land in one of the geologically youngest spots on the moon. The regolith there is exceptionally thin, which means you will get a lot of young looking craters, and they will plow into thin soil.

This type of crater was discovered in Lunar Orbiter images and recognized as a probe of the depth to bedrock. They can be used to map variations in regolith thickness. Apollo 12's backup landing site - a pinpoint landing spot in Apollo Site 5, was near a crater of this type.

Well, so I didn't discover anything new, but anyway, these craters are cool, especially at such high definition.

Here is the Surveyor 1 site
I downloaded the TIFF (!pain!) and then adjusted the dynamic levels, cropped, destriped, and a little blow up (whew!) (Dear LROC Team, please put non-annotated images up for us noodles to noodle with....like the Apollo sites!) Cheers -------------------- CLA CLL

LRO is now orbiting over Mare Crisium and the Sun is low over there.I hope it's imaging Luna 23 and 24 landing sites.

LROC news from LPSC - heard from a thoroughly disreputable source (I'm only kidding, L!) - LROC has seen Luna 24 and Lunokhod 2. Results should be shown in a talk tomorrow. Maybe there will be a release soon after. Luna 24 apparently landed on a crater rim, which may have affected its sampling ability.

Luna 24 apparently landed on a crater rim, which may have affected its sampling ability. That's great news Phil! Have been looking forward to those images for some time. Are they sure it's Luna 24 and not Luna 23 (which landed nearby), 23 was the one which damaged its drilling equipment on touchdown. |

I can't tell you yet. Maybe more tomorrow.

Update. Mark Robinson showed images of three Luna landers, 20, 23 and 24. Luna 20 shows the shadow of its sample delivery arm "as if it's waving at us" according to Mark. Luna 23 is sitting on the very edge of a crater only 2 or 3 m across. No obvious sign of why it couldn't collect a sample. Luna 24 is on the rim of a c. 20 or 30 m fresh crater, which may explain an odd thing about its sample... not the amount, but the fact that it differed from the surrounding area as measured by remote sensing... it seems to consist of freshly exposed subsurface material rather than the space-weathered material all around it.
Beautiful pics - let's hope they are released very soon. Phil -------------------- ... because the Solar System ain't gonna map itself.

No release yet of the Luna images (too bad, where are they?!?)
in their place, this image of the Marius Hills Hole has been published on the LROC image browser http://wms.lroc.asu.edu/lroc_browse/view/M114328462R |
