Moscow. July 31. INTERFAX-The atmosphere was cleaned in the Nauka module, it is integrated into the Russian segment of the ISS, the head of Roscosmos Dmitry Rogozin said.
"The atmosphere was cleaned in the MLM (multifunctional laboratory module "Science" - IF), the final air samples were taken( norm), an hour ago our crew entered the module "Science". Congratulations! MLM is integrated into the Russian segment of the ISS, " Rogozin said on Twitter.
According to Roscosmos, on Saturday, the crew entered the MLM to start full-fledged activities in the module after the completion of the air purification filters and began installing ventilation.
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.
"Today at 20:47 Moscow time, Roscosmos cosmonauts Oleg Novitsky and Pyotr Dubrov opened the transition hatches and boarded the new Russian module Nauka," the state corporation said in a statement on Friday.
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.
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 manovacuum meters 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 "Science", because of which the station was turned around by 45 degrees. To compensate for the pulse, 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.
According to the US agency, due to the situation, the launch of the Starliner spacecraft scheduled for Friday to the ISS was postponed. Roscosmos said that the postponement of the launch was due to bad weather conditions.
"The flight of the International Space Station continues according to the planned program," the state corporation reported.
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.
