Sergey Gorbunov, press secretary of the general director of Rosaviacosmos, Russia's space agency, told Interfax Friday that the first space tourist - US citizen Dennis Tito - will definitely be launched with the next crew to the International Space Station, as planned. The question has been decided.

Their Russian Soyuz TM-32 spaceship was expected to dock with the ISS at 1:10 pm Moscow time (0910 GMT) on April 30, mission control added.

However, the head of the Russian space agency Yury Koptev and NASA chief Daniel Goldin have yet to give Tito the final go-ahead after US objections that Russia had sold the 60-year-old businessman a 20-million-dollar ticket for the flight.

Koptev and Goldin were expected to discuss the matter later Friday during a telephone conference postponed from earlier in the week.

A telephone hookup between senior Russian and American space officials to air concerns over Russian plans to send a wealthy tourist to the Space Station now appears to be off again.

NASA Director Dan Goldin told reporters Thursday he had no plans to discuss the issue with Russian space boss Yuri Koptev on Friday.

Meanwhile, Tito is training according to schedule, the Russian agency's press service said. He and two Russian cosmonauts would fly to the ISS aboard a spaceship of the Soyuz TM class, to be taken into space by a Soyuz-U carrier rocket from the Baikonur cosmodrome in Kazakhstan.

Russian space experts say tourist flights to the ISS are inevitable and that all the countries involved in the ISS project should have a single official position on them. All these countries have repeatedly discussed the problem.

On Tuesday, Tito, crew commander Talgat Musabayev and flight engineer Yuri Baturin were at Baikonur training onboard the ship that would take them to the ISS.

The three are to return to Star City near Moscow on Wednesday for their final preparation period, which includes medical tests and work on a scientific research plan.

They will leave for Baikonur on April 23.

Meanwhile the current Soyuz parked at the station has redocked after undocking Wednesday. The Soyuz, piloted by Russian cosmonaut Yuri Usachyov, flew around the station before manual docking. James Voss and Susan Helms of the United States are crew members on the flight.

The re-docking was needed to make the axial docking unit available for a Soyuz TM-32 that will take off from Baikonur on April 28 to deliver a new Soyuz emergency crew return vehicle to ISS.
