Orbital

This is the brilliant book that won the Booker Prize this year. It is about 24 hours in the life of the International Space Station and details the thoughts and relationships of the six people on board. Really interesting insights into training and the psychology of it all. There are some lovely bits of physics. On page 109, she explains that the feeling of weightlessness is not due to lack of gravity but about falling towards the Earth constantly; not hitting the Earth because the Earth is curved by an amount that means the Earth's surface falls away at the same rate that the spacecraft falls. I wish I'd understood that at school.
