Roscosmos, the Russian space agency, announced the results of the investigation on the failure of the mission of the Progress M-27M cargo spacecraft. The problem was found to be in the separation system between the spacecraft and the third stage of the Soyuz 2-1a rocket used to launch it. A new Progress mission to bringh supplies to the International Space Station could be scheduled for early July, probably using a Soyuz-U rocket, the version used until recently.
