Moscow. August 4. INTERFAX-The incident with the Nauka engines did not cause damage to the ISS, but the consequences may manifest themselves in the future, said Sergey Krikalev, executive director of Roscosmos for manned space programs.
"There is probably no damage. Nothing has broken off from the station, I can reassure you, but experts will assess how much we have loaded the station, what consequences, " Krikalev said in an interview with the Rossiya 24 TV channel (VGTRK).
"Turning on the engines is a dynamic. The station is a rather delicate device, both the Russian segment and the American one - everything is done as easily as possible. The additional load, it causes a load on the drives of solar panels, on the farms on which all this is installed. Now, of course, experts will analyze the consequences, and now it's a little early to say about the seriousness, but, of course, this is an emergency situation that will need to be analyzed in detail," Krikalev said.
According to him, the specialists of Roscosmos will soon determine the consequences of the incident.
On July 29, the Nauka module successfully docked to the ISS.
On Thursday, after the module docked to the ISS, the Russian crew planned to open the hatch of the transition compartment of the Zvezda module, and then open the hatch of the Nauka module and enter the living area of the instrument-sealed compartment, but they failed to do this. Later, the MCC specialist, during negotiations with the crew, asked the astronauts to attach manovacuummeters to the hatch of the Nauka module to check the pressure.
Earlier, as reported in NASA, there was an abnormal activation of the engines of the "Science", because of which the station was turned by 45 degrees. To compensate for the impulse, the engines of the Zvezda module and the Progress cargo ship had to be used. Roscosmos explained the incident by working with fuel residues in the Nauka module.
On July 30, an operation was carried out on the ISS to purge the Nauka fuel system with helium in order to ensure safety.
According to Roscosmos, cosmonauts Oleg Novitsky and Pyotr Dubrov went on board the Nauka module, which docked to the ISS on Thursday. It was noted that Novitsky and Dubrov will perform a control inspection of the compartments, take air samples and install an atmosphere purification filter unit.
The launch dates of the module were repeatedly postponed. Initially, the launch of the Nauka module was scheduled for 2017, but it was postponed to 2018 due to a blockage in the fuel system. The blockage could cause a breakdown of the ISS propulsion system, so the module was returned to the manufacturer for revision. Later, Rogozin said that the main cause of problems with the fuel system of the "Science" was not a blockage, but a marriage.
