Cosmonaut Anatoly Levchenko, who died last week of a brain tumor, had been scheduled to fly the first manned Soviet space shuttle, the official media said Wednesday.

Levchenko's death, announced Tuesday, was believed to be a blow to Moscow's plans for a manned shuttle mission. Western sources had identified Levchenko as one of two cosmonauts who conducted test flights of the shuttle, and the offical Tass news agency confirmed he had been selected as a crew member.
