GORKI, April 30. /TASS/. Russian Deputy Prime Minister Dmitry Rogozin said on Thursday that the absence of versions of the failed launch of the Progress M-27M cargo spacecraft is strange.

"There are no substantial versions so far, it's very strange," he said.

The unmanned Progress M-27M spacecraft, carrying almost 3 tons of supplies, was launched on April 28 but failed to dock with the International Space Station (ISS).

The Russian Space Agency (Roscosmos) chief, Igor Komarov, said on Wednesday the possibility of dumping Progress M-27M was being considered.
