First Stage Testing of "Soyuz-5" Rocket Yesterday, fire tests were carried out at Roscosmos' facility, the Scientific and Testing Center of the Rocket and Space Industry, marking the final stage of ground testing. The stage features the RD-171MV rocket engine, generating 800 tons of thrust by NPO Energomash and using kerosene and liquid oxygen as fuel components for environmental friendliness. The successful verification of the interaction between the first stage systems and the engine, with the RD-171MV operating for the designated 160 seconds, paves the way for the start of flight-design tests for the "Soyuz-5" carrier rocket developed by Roscosmos' Rocket and Space Center "Progress." This rocket is designed for launches under the joint project "Baiterek" with Kazakhstan, focusing on launching automatic spacecraft into various near-earth orbits with the use of booster blocks.
