Despitepaying millions for a flight to the International Space Station (ISS), the nexttourist to the orbital platform does not plan to spend all of his time at play.

GregoryOlsen, an American scientist and entrepreneur set to become the third spacetourist to visit the ISS, will participate in a trio of experiments for theEuropean Space Agency (ESA) during his eight days aboard the station.

"I think it'svery important to him," said Stacey Tearne, a spokesperson with the Arlington,Va.-firm SpaceAdventures, which brokered Olsen's flight. "He wants to experience spaceand weightlessness. But being able to come back to research, and have some data...thatwill be very fulfilling for him."

Olsen willlaunch to the space station with ISSExpedition 12 commander Bill McArthur and flight engineer Valery Tokarev,who will take over control of the orbital laboratory from its currentcaretakers - cosmonaut Sergei Krikalev and NASA astronaut John Phillips of Expedition11. A Soyuz TMA-7 spacecraft is scheduled to carry Expedition 12 and Olsentoward the ISS on Sept. 30 at 11:54 p.m. EDT (0354 Oct. 1 GMT), NASA officialssaid.

Olsen's $20-millionspaceflight will follow the successful ISS flights of space tourists Dennis Tito in 2001 and MarkShuttleworth in 2002. Those flights, like Olsen's, were also brokered by SpaceAdventures.

As part of theagreement with the ESA, Olsen will serve as the test subject for two humanphysiology studies in microgravity. Included among them is the MotionPerception (MOP) study to better understand motion sickness, as well as a studyof lower back pain which ISS astronauts experience during long-duration spaceflights.Olsen will also help collect data on the different types of microbes living aboardthe station and its crew, Space Adventures officials said.

"Learninghow to live and work in space and my upcoming mission are truly a dream cometrue for me," Olsen said in a statement released Monday. "But I am first andforemost a scientist, and I am going to carry out real science aboard the ISS...Ido not consider myself a space tourist."

"He justcan't wait," said Tearne, who has been communicating with Olsen via e-mail, ofhis upcoming mission. "He's like a kid in a candy store."
