Lunar rocks. Surveyor 7. The top one shows cracking. The cracks are about 6 mm or quarter on an inch wide for scale. Cracking in boulders have been images by both Surveoy & Apollo. This is partly due to the day & night temperature extremes. In the early Lunar afternoon, about 8 days after sunrise, the temperature of the surface climbs to 117 Celsius / 390 Kelvin. Just before sunrise, the surface temperature at the equator & mid latitudes drop to about Minus 167 Celsius / 106 Kelvin. That is almost cold enough to liquify the Earth's atmosphere!!!!!!! A day - night difference of about 284 C / K. The moon has one of the most extreme day - night temperature extremes in the solar system. The planet Mercury is even more so, with day temps reaching 428 C / 701 K & dropping to Minus 186 C / 87 K, a difference of 614 C / K. So Mercury may well have some impressive split boulders too. Asteroid 433 Eros also experiences something similar. Its extreme seasons & eccentric solar orbit, shows maximums of around 100 C / 373 K & minimums of around Minus 200 C / 73 K. A range of 300 C / K. The final image taken of the Near / Shoemaker spacecraft during descent to the surface of 433 Eros, shows a nice split boulder, about the size of a large office desk. Below.

I trawled this out. Lunar Orbiter 1. Crescent Earth as seen from just behind the Moon. Farside Crater Tsiolkovskiy is clearly seen. However Tsiolkovkiy can never be seen from Earth, likewise the Earth will never be seen from Tsiolkovskiy. From this vantage point, it is possible to see both.

That's a very dark crater!! <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters. Monsters from the Id. I really, really, really, really miss the "first unread post" function </div>

Hi MeteorWayne. It is, nice dark smooth(ish) lava!!!!!!!!!! Tsiolkovskiy is one of the very few farside features to have been flooded by lava. Below is another of Tsiolkovskiy.

From Chuck Wood. Briggs is a modest crater stuck on the edge of the Astrophysicistsâ€™ Graveyard. The 37 km diameter crater is far enough from the lunar central meridian that mostly from Earth we see a shallow interior with a central peak. The best Earth-based shot I know of is the one in the Graveyard. But from overhead in orbit, Briggs has a lot of history to tell. Its rim is fairly sharp and continuous so it is a relatively young crater, although it has been partially surrounded by Procellarum lavas. Briggâ€™s interior is not deep with terraces leading down to a flat-floor. The crater lacks terraces except for a hint of them on its south rim, and its floor is wreathed by ridges that give way to a dense circular network of rilles. The southern half of the inner floor is smooth, but it is not mare lavas because its not dark at full Moon. The shallow floor, concentric rilles, and location near a mare all qualify Briggs as a floor-fractured crater. But what is especially interesting is that the northern third of the floor is covered by a fan of debris that has slid inward from a noticeable wall scallup. The edge of the debris is clearly visible and it covers the concentric rilles. This means that the little notch on the northern side of Briggsâ€™ rim formed after the floor-fracturing. Unfortunately, we donâ€™t know how long after the formation of the crater that the fracturing occurred. But it is easily possible that it was millions of years later. If so, the northern rim collapse notch was not created during the formation of the crater. This suggests that significant rim modifications might occur long after craters form.

How did that notch in Briggs crater form? thanks. <div class="Discussion_UserSignature"> <div class="Discussion_UserSignature" align="center">- - - - - - - - - - - - - - - - - - - - - - </div><div class="Discussion_UserSignature" align="center">I really, really, really miss the "first unread post" function. </div> </div>

Hi silylene, I think it is a landslide. I will look for other images of Briggs Crater to confirm. Thank you for your question. It makes me look for more info.

Hi Moon-fans, If it hasn't already been posted here (I did a quick search and couldn't find any reference), there is a new project underway to convert all of the original Apollo photography to digital form, directly from the original film (which have been in storage for decades). The home page is here: http://apollo.sese.asu.edu/index.html This should give a significant improvement in the quality of photos available from those missions, since it seems that the original film was only transferred once, and then multiple copies were made of those transfers, so that what we have generally available now are second (or third)-generation transfers. Regards

Thanks Chode, That is absolutely amazing. <img src="/images/icons/laugh.gif" /> It s almost like going back to the Moon. I think that many new discoveries await in these images & that with the digitalization of them, these will become apparent. ------------------------------------------------------------------------------------------------- Copernicus & Mare Imbrium.
