Schickard (crater)

Schickard is a lunar impact crater of the form called a walled plain. It lies in the southwest sector of the Moon, near the lunar limb. As a result, the crater appears oblong due to foreshortening. Attached to the northern rim is the lesser crater Lehmann, and to the northeast is the even smaller Drebbel. Southwest of Schickard is Wargentin, a lava-flooded plateau.

Schickard has a worn rim that is overlain in several locations by smaller impact craters. The most prominent of these is the irregular Schickard E across the southeastern rim. The floor of Schickard has been partially flooded by lava, leaving only the southwest portion uncovered and rough-textured.

Schickard's floor is marked with a triangular band of lighter-albedo material, leaving relatively darker patches in the north and southeast. This feature is more prominent when the Sun is at a relatively high angle. There are also multiple small crater impacts on the floor, most notably in the southwest.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Schickard.

gollark: They can actually access external stuff.
gollark: Often I just use computer cases, though.
gollark: Which makes it MILDLY less annoying.
gollark: Being able to program microcontrollers is mildly cool, but it also means I have to wait for an electronics assembler, they can't interact with external components, and they're very irritating to debug (apparently *deliberately?!*). CC computers boot fairly quickly anyway.
gollark: CC workflow for setting up a computer to do things:- (auto)craft computer- place computer- write code/download code onto computer as startupOC workflow:- figure out what cards/other components it needs- queue autocrafting for everything- wait a while while autocrafting runs, and possibly converts some coal into diamonds- pull autocrafted stuff out of ME network, put into computers, be sure to get the right items- find openOS disk, disk drive- install openOS- write/download code- either move code to `boot` or work out how `rc` works
