'N Sync singer fit to be 'N Space

Bass says doctors have given him the OK to fly in space.

(CNN) -- Boy band singer Lance Bass says he has been medically cleared for space travel.

"I'm pretty confident we will be able to pull this off. I know physically I can do this," Bass told a packed news conference in a luxury hotel in Moscow, according to Reuters.

Bass, a member of the band 'N Sync, hopes to become the next tourist to hitch a ride on a manned Russian rocket to the international space station. He has been undergoing tests at the Russian Institute for Biomedical Problems to evaluate his fitness for the journey.

The pop star still has to get permission from the Russian Aerospace Agency to make the trip, scheduled to launch in October.

Bass underwent tests at Russia's Institute of Biomedical Problems to determine his fitness for space travel.

A spokesman for the agency told CNN Friday there had been no discussions with Bass about a possible space flight, and said no decision had been made about the next space tourist.

But David Kreiff of Destiny Productions, a Los Angeles television production company that has committed to helping fund Bass' trip, said the spokesman was misinformed.

"Things are progressing on a very high level," Krieff said.

He said paperwork had been sent to the Russian space agency and money had been put in escrow to fund the venture.

"We're looking at upwards of $14 (million) to $20 million," Krieff said of the cost of the trip. That's in line with what the two previous space tourists, American Dennis Tito and South African Mark Shuttleworth, paid for the privilege.
