So now you know about a lot about Straker’s issues. He’s had a very rough upbringing and he’s stranded in a little town deep within the rim of Shackleton Crater with people that hate his guts. In Chapter 2 he gets tested in a different way.
Shackleton is located almost exactly at the moon’s south pole, and is believed to be a so-called “Crater of Eternal Darkness.” Because the temperature stays so low down there, it’s an excellent potential location for an infrared telescope. That’s the theory anyway.
Here’s a page with some cool images from NASA about the crater. http://sservi.nasa.gov/articles/detailed-characterization-of-shackleton-crater/
To us, Shackleton Crater is an interesting and mysterious location on the moon, but to Straker it’s a dump.
