Worth two hours of observation.
As NASA's Orion project fell to pieces, most scientific missions use robotic drones, and the Space Shuttles approach their date with decommission, it seems that the Astronaut generation has ended, but the next generation has already begun. Thousands of rich entrepreneurs have already paid for tickets to outer space, some even paying $200,000 to go through a few weeks of training before going up in space for up to 10 days, even staying on the International Space Station! As time goes on, technology advances, and initial costs are paid off by early sponsors, space tourism could be the next big thing, even helping make space travel profitable, although we would first have to get it mainstream enough that it wouldn't require any more training than sitting in the emergency exit row of an airplane.
