For those with an interest in technical (and psychological) subjects, there is an excellent series showing on Sunday evenings at 8pm on the National Geographic TV channel. Although this is the 2nd Series, my provider Virginmedia has the 1st Series available as well as a couple of other MARS/SpaceX programmes.

The series is a mixture of fictional story and real documentary, an extremely interesting mix of fact and fiction, and a good illustration of the likely technical/human problems, and how to overcome them.

Well worth finding and watching.
