Dr Vaughn Clift, a medical doctor, is, as far as he knows, the only Australia working for NASA (National Aeronautic and Space Agency) at the Johnson Space Centre, in Houston Texas. He develops medical technology for astronauts, ways of monitoring their health while in space. Amongst other thins, he has invented a simple way of collecting and preserving blood without the need for refrigeration. Dr Clift shows us the sort of work he does, while taking the viewer on a guided tour around the Space Centre. We see the Space Shuttle Trainer, also the chamber where researchers are locked away for months to study recycling, and the famous 'Vomit Comet', an aircraft which dives to simulate zero gravity. Dr Vaughn is not only amusing, sometimes hilarious, host, but is passionate about space.
