Russia and Kazakhstan are set to complete construction on a new unmanned spacecraft launch complex by 2008-2009, the top Russian space official said Friday. Anatoly Perminov, the head of Russia\'s space agency, also said that would-be U.S. space tourist Gregory Olsen is unlikely to travel to space this October on the next Soyuz trip, although he has passed the necessary medical exams. Kazakhstan and Russia have agreed to jointly develop Baiterek, a new launch complex on the Baikonur cosmodrome in Kazakhstan, which Russia leases from the Central Asian nation. Baiterek is designed for the environmentally friendly Angara unmanned rocket, an alternative to the Soyuz booster now in use. The Kazakhs have long campaigned to minimize pollution from rocket launches from their territory. Perminov said Baiterek will be completed in 2008-2009. (AP)
