We'll save the diagrams of the Slaughterhouse (Abbatoir) and Machine Tools part 1 and 2 for a rainy day, and instead plump for a subject that is vaguely topical but still about a month behind everyone else – a position I frequently find myself in – with a celebration of the moon landings.
The most illuminating parts of this illustration are obviously no 15: piece of rock, no 40: window, and no 21: access flap, named with intriguing vagueness given its location just below the groin department. There is a further access flap for the 'purge valve'. What is this for? I don't know, but it suggests that the extreme pressure of being a really big deal in space travel may lead to an unhealthy relationship with one's freeze-dried dinner.
You can click on the image to make it bigger. I only recently discovered this. We are on a journey, you and I. Another journey I am on is trying to scan things squarely, but I'm not expecting to arrive at that destination any time soon.
