Two nice boulder tracks on Tsiolkovskiy's peak. I like the one made by the elongated boulder.

QUOTE (Phil Stooke @ Sep 1 2009, 08:40 PM)  A fantastic new picture today, Tsiolkovsky's central peak, with approximately a zillion boulder trails... Here is an odd set of boulders, sitting in the the middle of a area of craters, but not part of a crater. Is it one boulder that fractured on landing?

Imagine seeing that happen...

Here's a spectacular group of huge boulders near the top of Tsiolkovskiy's peak. Must be quite a scenery seen from the ground. Can you imagine yourself hiking in there?

I can imagine some 1/6 g rock scrambling and bouldering going on there! Looking at such rough terrain makes me wonder if there are any (much) smaller versions of the permanantly shadowed craters at the poles? A crevice or crater in the middle of such an outcrop would be sheltered from sunlight at comparatively low lattitudes I imagine.

That's a very interesting point. In effect it's what the Apollo 16 astronauts looked for at Shadow Rock, south of North Ray crater, but that was really not a very good candidate. One objection to the idea of volatiles collecting in a crevice in a rock pile is that they may not last long enough. Small impacts probably break up boulders often enough that the crevices change or disappear, or get filled with ejecta, on too short time scales. Still, it's certainly possible. Makes me wonder about the much-talked-about idea of lava tubes as habitats - would they contain ice patches too?

I'd think so... in fact seeing as how easy it would be to make a lunar cold trap there should be a lot of them in various forms. It'd just be a case of picking the oldest and least disturbed. An ancient cold trap that got hit by a meteorite would probably leave a fingerprint of volatile species in the lunar exosphere.

here is a context image for the Tsiolkovskiy image...I am not sure were to lay the strip, but I see now why there are boulder tracks and collections of boulders

Surely...the jitter-bug
 Those LROC guys just don't get in enough dance routines in between uploading images, I'm thinking  John |

New data from all LRO instruments are expected to be released on Thursday... should be good!

Really? Awesome. Guess I'll have something productive to do during our Thursday morning staff meeting

A nice new image of part of Shackleton at LROC today.

COOL. Thanks for the heads up. I love the "The full NAC mosaic reveals a shelf on the southeast flank of the crater that is more than two kilometers across and perfectly suitable for a future landing."
