A problem with a Soyuz spacecraft could delay the launch of the next crewed mission to the ISS by several weeks, Russian officials said Friday. The descent capsule of the Soyuz TMA-04M spacecraft, slated to launch in late March, did not pass a pressure chamber test recently and will have to be replaced, an industry source told Interfax. That would delay the next mission to at least mid-April and possibly until May, and the following one, planned for the end of May, to at least mid-June. Unlike last fall, when a Progress launch failure forced the ISS to step down to a three-person crew for about three months, this potential delay is not expected to affect the station's ability to maintain a six-person crew.
