Video: Next International Space Station crew in Star City

The next launch of a Soyuz spacecraft carrying three space station fliers has been delayed indefinitely after testing at the Baikonur Cosmodrome in Kazakhstan revealed an unspecified technical problem, the Russian space agency announced Saturday.

A privately-funded airlock from Nanoracks will head for the International Space Station this weekend in the trunk of a SpaceX Cargo Dragon capsule, adding to the orbiting lab’s capacity for scientific experiments in another milestone for commercial space development.
