Space Tourist Gregory Olsen Back to Training

U.S. Millionaire Gregory Olsen, 58, was originally slated to fly to the International Space Station this past April, but according to this 2004 NASA internal memo, a mystery health ailment derailed his training and sent Space Adventures (the company responsible for Olsen's, Dennis Tito's, and Mark Shuttleworth's Space trips) looking for a new candidate.
Fast-forward one year and Olsen's trip is back on schedule. And not a moment too soon.
Unlike most past and potential Space tourists, Olsen is a true scientist, intending to conduct actual scientific research that he hopes will yield meaningful results in the near future.
Olsen will surely get a thrill out of flying up and back to the station. Considering he's paying upwards of $20 million for the trip, he better get a thrill!
But I'm glad to see someone doing it for reasons other than the view. I can't believe more scientists aren't clamoring for the opportunity to work in Space. Crystal growth, imaging experiments, physiological examination---there is research a-plenty in orbit.
Now, if we can just get the cost down to something more reasonable...

By the way, in case you are considering taking the trip yourself, consider these Space tourist guidelines prepared by Russian and US Space administrators.
