The engines of the Nauka module turned on unplanned; to compensate for the impulse, the engines of the Zvezda module had to be used. This was announced by the announcer of the broadcast of the negotiations of the station’s crew with the Earth, which is being conducted by NASA.
Due to an abnormal start of the engines, the ISS turned 45 degrees.
“The module’s engines began firing at 12:45 pm ET inadvertently and unexpectedly, turning the station 45 degrees. The restoration work returned the station to its normal position, nothing threatens the crew, ”- it says on the space agency’s Twitter.
Ground specialists regained control over the station and all ISS systems are normal.
The press service of “Roskosmos” explained this incident by work with the remnants of fuel. “The process of transferring the“ Science ”module from the flight mode to the“ docked with ISS ”mode is in progress. Work is underway with fuel residues in the module, ”the state corporation said.
On July 29, the Nauka module successfully docked to the ISS. Cosmonaut Oleg Novitsky did the docking manually, because the automatics did not work.
The rocket was launched on July 21 at 17:58 Moscow time. After starting, the module encountered malfunctions in the fuel system, but they managed fix and enable propulsion systems.
The “Science” module began to be developed back in 1995. It was planned to be launched to the ISS in 2007, but the launch has been postponed many times. The long delay was due to a manufacturing defect that left metal shavings in the fuel system.
This module should become the main platform for experiments in the Russian segment of the ISS. Total Roskosmos plans to carry out 13 experiments in various directions, among which – “Drop-2” (space technologies), “Aseptic” (space biology and physiology), “Mirage”, “Vampire”, “Fullerene” (all three – space materials science), ” Vitacyc-T “(space biology and physiology),” Rakurs “(exploration of the Earth from space) and others.
Inside the module there are several workplaces for scientific equipment, outside there are universal adapters for installing research equipment.
Nauka also delivered water containers, handrails, fans, cables and other cargo to the ISS.
Flight tests of MLM Nauka will end one year after its launch from the Baikonur cosmodrome.
