Roskosmos has successfully carried out bench tests of the engine of the third stage of the booster rocket Soyuz-2
The Russian Federal Space Agency, or Roskosmos, has successfully carried out bench tests of the engine of the third stage of the booster rocket Soyuz-2, Roskosmos spokesman Vyacheslav Davidenko has said. “On Wednesday, specialists of Roskosmos successfully conducted ‘fire’ tests of the unit of the third stage of Stage 1b carrier rocket Soyuz-2 on bench of t research Institute of Chemical Engineering,” he told reporters on Thursday. The goal of the tests is to confirm serviceability of engines and several systems, and of correctness of design solutions. The successful tests are a “key event for making a decision on the beginning of flight test of the Stage 1 b carrier rocket Soyuz-2 with the launch of the French spacecraft Corot”, Davidenko said. The Soyuz 2 rocket that is being manufactured in Russia is permanently modernized. The Stage1b rocket was first test-launched from Russia’s northern cosmodrome Plesetsk in November 2004. The carrier rocket with the European satellite Metop is to blast off from the Baikonur cosmodrome in this year’s June. The first launch of the Stage 1b Soyuz is planned for the second half of 2006. The further plan is to manufacture the carrier rocket Soyuz-ST that will be launched from the Kourou cosmodrome in French Guiana. The Roskosmos press service told Itar-Tass that Soyuz-2 was being made in two modifications - with an old engine of the third stage (Stage 1a version) and with a new, more powerful Stage 1b engine.
