The Nauka module has acquired an additional portion of its own history. The note.
On July 8, 2021, Roscosmos reported that the Pirs module of the ISS could be flooded on July 23, 2021. (The Nauka module will take the place of the Pirs on the ISS).
However, on July 22, 2021, information appeared that the time for undocking the Pirs module from the International Space Station (ISS) will be determined after a series of works (routine calculations and operations).
According to unconfirmed reports, Nauka had problems with starting its engines, because of which there is a risk that Nauka will not be able to get to the ISS. Naturally, it is premature to believe this data without official information. "The Russial module Nauka (MLM-U), which successfully launched from the Baikonur cosmodrome and entered its target orbit yesterday, encountered malfunctions in the fuel system, said "N + 1" [internet edition] a source in the rocket and space industry."

According to the messages that appeared, on July 22, 2021 at 18:07 Moscow time, the engines of the module were turned on for 17.23 seconds. The impulse value was 1 m / s. The second switching on of the engines took place at 20:19 Moscow time and lasted 250.04 seconds. The impulse was 14.59 m / s.
"The decision on the time of undocking the Pirs module from the ISS will be made after routine calculations and operations have been carried out," the Roscosmos state corporation noted on July 22, 2021.
Perhaps the inclusion of the module engines (which took place) was indicated by the words "the carrying out routine calculations and operations."
A new date has been set. Specialists in the rocket and space industry have decided to schedule the flooding of the Pirs module on July 24, 2021.
