According to cosmonaut Oleg Novitsky, the engines on the new Russian module "Science" unplannedly turned on.
Cosmonaut Oleg Novitsky on board the ISS reported to the MCC about the unplanned activation of the engines of the new module, RIA Novosti writes.
“I can confirm that the engines are still working and we can feel it,” the astronaut said. To compensate for the disturbance from the turned on engines, it was necessary to activate the engines of the Zvezda module. The station position error in space decreases.
In addition, the engines of the Progress MS-17 spacecraft docked to the ISS were turned on.
Earlier it became known that the crew members of the station opened the transition hatch between the modules "Science" and "Zvezda", but soon they were asked to close it.
Docking of "Science" with the ISS was carried out today, at 16:29. Despite the difficulties previously reported by the media, the module was docked with the nadir Zvezda node in a regular manner. The operation was carried out in automatic mode.
Thus, Russia received a new ISS module for the first time in ten years. It became one of the largest in the history of the station. MLM weight - 20 350 kilograms.
"Science" will make it possible to conduct a number of important experiments: they relate to both fundamental science and various areas of the social sphere. It is assumed that the module will be able to operate as part of the station until the end of this decade.
UPD: According to Roskosmos, the engines were turned off. The corporation explained the incident by "working with fuel residues." The engines started at 19:45 (Moscow time), during the integration of the module into the ISS. This led to a change in the position of the station in space by 45 degrees. No harm was done to the station or the crew, NASA confirmed.
