"The mechanic aspect of the docking was reliable, without any remarks registered. This resulted in the closure of both docking mechanisms: the station and the module. Due to a short-term software failure, a direct command was mistakenly executed to turn on the module's engines for withdrawal, which entailed some modification of the orientation of the complex as a whole", Solovyov said.
This was quickly fixed by engines of Russia's Zvezda module, the official recalled.

/ "At the moment, the station is in its normal orientation, all the ISS and multipurpose laboratory module systems are operating normally. A reliable internal power and command interface was created, as well as a power supply interface, which connected the module to the station," Solovyov concluded.
The Nauka module was launched to the ISS from the Baikonur cosmodrome in Kazakhstan onboard a Proton-M carrier rocket and successfully docked with the ISS on Thursday.
Later, Russian cosmonauts reported that Nauka's engines had unexpectedly activated, which led to a change in the position of the station. The ISS engines had to be switched on in order to compensate for the operation of the Nauka engines.
