Crater 308

I haven’t got time to post much today – WordPress was down earlier when I had a bit of time and now I’m going to watch the highlights of England’s Test victory against Pakistan in the cricket today, which they achieved by bowling out their opponents for only 80 runs in the second innings.

Nevertheless, as a quick filler, I thought it would be nice to show this wonderful image of the crater Daedalus, formerly known as Crater 308, which is located on the far side of the Moon. Not the dark side, by the way, the far side of the Moon gets just as much sunlight as the near side!
This is one of the images I’ve been working on as part of the project Beyond Entropy for a forthcoming exhibit at the Venice Biennale of Architecture which opens at the end of this month. I won’t say too much about the exhibit I’m involved with, except that it explores the way higher-dimensional information can be recorded in surfaces of lower dimension, like a kind of architectural holographic principle. I was particularly struck by the way the pattern of cratering on the Moon yields information about its formation history, which is why I went looking for dramatic examples. This – taken during the Apollo 11 mission- is my favourite image of all those I’ve looked at. I love the complexy topography, its textural contrasts and the way the shadows play across it.

Daedalus is an impact crater that formed about 3.75 to 3.2 bn years ago. It’s about 93km across. The crater looks relatively fresh; showing sharp-ish-looking rims all around with sequences of wonderfully-preserved terraces down onto a pock-marked, flat floor consisting of numerous craterlets and a central peak divided up into two to three well-defined hills. You can also see the effect of more recent impacts in and around it.

Talking of impact, I wonder if I can get this project into our REF submission?
