Russian officials dispute the idea that there is a problem.
NASA administrator Daniel Goldin told a House subcommittee Wednesday that Dennis Tito, the California tycoon who ignored the agency's recommendations and paid the Russians for the opportunity to go into space, has caused anxiety among space workers who overseeing the mission's safety. Mr. Tito does not realize the efforts of thousands of people, United States and Russian, who are working to protect his safety and the safety of everyone else. NASA and other partners in the space station objected to Tito's space flight, claiming that the Californian was not properly trained and that the station was not ready for amateur space trippers. Russian officials have denied the allegations, saying Tito was spending his time making videos and staying out of the way. Everyone is getting on with their work and there have been no complaints from on board.
