KOROLYOV, Russia U.S. space tourist Dennis Tito, clearly delighted with his stay on the International Space Station, pledged to encourage others to follow his example and said one need not be "superhuman" to go into space, Reuters reported on Tuesday. Tito, who has reportedly paid $20 million for his week-long journey, arrived aboard the station on Monday with two Russian cosmonauts after their Soyuz capsule docked with the complex. Television pictures showed him beaming as he floated weightlessly through the cabin of the station's Russian segment. Tito told a news conference staged by mission control outside Moscow that he felt fine and that crew members were treating him well. He promised to do what he could to bring other enthusiasts aboard despite the prohibitive price tag. "If I have anything to say about it, I will do my best to communicate to people how great an experience this is. One does not have to be superhuman to adapt to space," he said. "It's very do-able. Unfortunately, it's very expensive at this point, but there are others who can afford this and I would like to encourage it. That's what I hope to accomplish." He described the flight as "everything and well beyond what I would have expected. It's time for me to help other people to achieve their dreams." Tito's fare-paying ride prompted a dispute between Russian space officials, keen to collect his fee, and the U.S. space agency NASA, which said the $95 billion space station was no place for an amateur with no space experience. But Tito, wearing gray pants and a blue T-shirt used by Russian cosmonauts, told reporters he had already visited the U.S. sector of the station despite NASA's insistence that he be escorted when venturing into it. "I ended up seeing the American segment probably within an hour of arriving at the station," the 60-year-old California millionaire said. U.S. crew members James Voss and Susan Helms, he said, had "gone out of their way to show me around, to give me some safety drills. They have done a great job." Russian crew members, including ISS commander Yuri Usachev as well as Yuri Baturin and Talgat Musabayev, launched aboard Soyuz with Tito at the weekend, had become "very close friends". Tito said suggestions that he would fall victim to motion sickness, as occurs with even experienced space travelers, had been exaggerated. He had felt slightly ill during his first hours aboard the station, but recovered quickly. "My expectations originally were that things would be not that comfortable, like sailing on a rough ocean," he said. "But it turned out it's very comfortable. I feel great. I have no feeling of space sickness. My face is a little puffy as are those of my crew members, because usually the adaptation causes the blood to go to your head from the rest of your body. Back on earth, wind and rain swept the Florida Peninsula on Tuesday forcing NASA to pass off the first landing opportunity for the space shuttle Endeavor. Endeavor left the space station on Sunday, just hours before Dennis Tito arrived with a Soyuz crew of Russian cosmonauts. If the Florida weather remains bad, and forecasters predict it will, attention will shift to an Alternate landing strip at Edwards Air Force Base in California's Mojave Desert, or NASA could choose to keep the shuttle in orbit to see if Florida's forecast improves. NASA would prefer to land the shuttle in Florida because ground crews can go right to work preparing it for its next mission. The seven Endeavor astronauts prefer Florida because that is where their families are waiting.
