The Russian Federal Space Agency has not yet decided whether a space tourist, British soprano singer Sarah Brightman, or a professional crewmember will fly to the International Space Station (ISS) in 2015, Roscosmos manned programs chief Alexei Krasnov said, answering a question from Interfax-AVN.

"It is premature to say for certain whether Sarah Brightman, a European astronaut or a Russian cosmonaut will fly there. This issue is still open. We will be able to give more concrete information a little later," he said.

Roscosmos does not hold any official obligations today regarding Brightman's visit to the ISS, Krasnov said.

A spokesman for the Space Adventures company's Moscow office told Interfax-AVN on Wednesday that this firm had finalized all of the agreements needed for Brightman's flight to the ISS as a space tourist.

All legal issues have been sorted out and the contract with Sarah Brightman has been signed, the spokesman said.

It was reported earlier that the British singer is expected to visit the ISS as a space tourist in October 2015.
