JOHNSON SPACE CENTER, Houston -- Guy Laliberte, a former street entertainer who founded the enormously successful Cirque du Soleil, says he doesn't plan any fire eating or stilt walking aboard the International Space Station when he visits this fall.

But he might try to teach his crewmates a few card tricks if he can figure out how to do it in weightlessness.

"Take out the fire part!" he laughed during a news conference Thursday at the Johnson Space Center in Houston. "I think this is out of the question by far. The stilts, I don't know how we we'll be using stilts up there.

"But I think there are a couple of little things, hopefully, that I have learned in my career of street entertainer that I will try to apply up there. ... I think I will be more like a kid in a candy store discovering things that those guys (professional astronauts already) know.

"I know what I can do on Earth, but what I'm really interested in is learning what their world is," he said. "Maybe I'll teach them a couple of tricks of cards, but I don't know in weightlessness how those things can take place."

Laliberte, a Canadian worth an estimated $2.5 billion, is believed to be paying upward of $35 million to visit the International Space Station as a "spaceflight participant," or space tourist, in a deal with the Russian space agency arranged through Space Adventures Ltd.

He is scheduled for launch Sept. 30 aboard the Soyuz TMA-16 spacecraft from the Baikonur Cosmodrome in Kazakhstan. His crewmates will be rookie spacecraft commander Maxim Suraev, a colonel in the Russian air force, and NASA astronaut Jeffrey Williams, a shuttle veteran making his second long-duration voyage on the station.

Laliberte will spend nine days aboard the lab complex before returning to Earth aboard the Soyuz TMA-14 capsule Oct. 11 with outgoing station commander Gennady Padalka and NASA flight engineer Michael Barratt. Williams and Suraev will remain aboard the space station as part of the Expedition 21 crew.

"First of all, I would like to say how privileged and honored I am to be flying with these two men," Laliberte said in Houston, where he is training for his upcoming flight. "I feel totally confident. They have been generous sharing with me their knowledge and their advice."

He said his primary objective is to complete his training, pass the exams and make sure he can take care of himself without bothering the station's professional astronauts.

"The first time that we met I said my intention, my first priority, is to be able to take care of myself up there," Laliberte said. "They helped me to focus on what I should know. At the end, I don't think I'll be a burden. I'm there and I'm committed, I'm a perfectionist. I intend to be ready.

"Yes, I'll probably need help at certain moments," he said. "But I think I'll be a contributer to the success of that mission. Hopefully I'll be well received. I intend to behave as a guest who has good manners. Simple as that."

Laliberte is the founder of the One Drop Foundation, dedicated to improving water conservation. He said he plans to hold a news conference in August to discuss his "Poetic Social Mission" to the space station and to unveil its theme and objectives.

He would not discuss specifics Wednesday, but the One Drop web site says "Laliberte's mission in space is dedicated to making an impact on how water, our most precious resource, is protected and shared. And he will be applying tools he has used so well for most of his life to bring about change: arts and culture."

While some professional astronauts have complained in the past that space tourists have no place on the station, Williams and Suraev both said they welcomed Laliberte.

"So far, my assessment has been very favorable," WIlliams said. "I think physically, mentally, emotionally he's getting himself prepared and he will be prepared for this adventure in his life."

Said Suraev: "He is really very eager to fly and he is charged with a lot of positive energy. ... He's just a good guy. Since (meeting him) my opinion hasn't changed. As the flight participant, as a crew member, he's a very, very good candidate."

Asked what he is looking forward to the most, Laliberte said "enjoying looking at planet Earth and space."

"I think this is a great, great opportunity of inspiration," he said. "And I intend to inspire myself as much as possible. And also, I would say living a human experience with the people I will be up there (with) and living that moment fully like I do on Earth."

He said his Poetic Social Mission "is a project that I'm very proud of, it is a mission that hopefully will bring and create awareness in regard to the situation of water around the world. As you know, I'm not a scientist, I'm not a doctor, I'm not an engineer. I'm an artist, a creator. And I'll try to accomplish this mission with my creativity and what life has given me as a tool."
