Umm.. yes it would be a lot harder, and take a lot more fuel to stay up for longer. They are only hitting 65mi AGL. That's technically in space, but just barely (either 62 or 50 miles depending on who's counting). To stay up for an hour or so, they would have to reach something near Low Earth Orbit (LEO). For reference, the ISS is in LEO, and it takes ~90 minutes to complete one orbit. It's orbiting at an altitude of 190mi. Besides, weightless is a rather misleading term. Gravity is still pulling them down at nearly the same rate as it is on the ground (minus a percent or so). They are just falling (decelerating) at the same rate as the craft, and hence have no apparent weight,
