The Russian module “Science”, which was launched on July 21 from the Baikonur cosmodrome and launched into the target orbit, encountered malfunctions in the fuel system. About it informs N + 1 citing a source in the rocket and space industry.
According to the interlocutor of the publication, in order to raise the orbit and approach the ISS, the module needs to turn on the engines four times, but due to a failure it may not have enough fuel for all maneuvers.
Source N + 1 suggested that too high a pressure was created in the fuel system, causing the bellows to rupture and leaking fuel into the gas space behind the bellows membrane. Consequently, some of the fuel may not get into the pipelines and to the engines, and this jeopardizes the module’s ability to reach the ISS.
At the same time, the interlocutor of the publication notes that similar telemetry data can create malfunctions in the valve system of the fuel system.
Some time ago, the engines were turned on for the first time on board the module, but it is still unknown whether the inclusion was done properly, he said.
Meanwhile, the press service of Roscosmos reported that there is no new data on the state of the module yet.
The rocket was launched the day before at 17:58 Moscow time. The “Science” module has successfully entered the near-earth orbit. Its docking with the International Space Station is scheduled for July 29.
