In these hours the story linked to Russian form Nauka It is holding “with bated breath” fans of astronomy and space technologies. As we know, the new module of the International Space Station was launched on July 21 after several years of its initial construction thanks to a Proton-M rocket.
Though Roscosmos and the general manager Dmitry Rogozin have always stated that the launch took place perfectly as well as the first maneuvers, some rumors of problems that would plague the new ISS module (which will arrive in a few days).
The Russian Nauka module turns on its main engines
The launch and separation of the three stages of the Proton-M rocket went correctly (the 3.5 ton Meanwhile, the #Proton-M rocket stage from the #Nauka launch is slowly coming down (most notably its apogee at the moment).
within a week in the atmosphere). What initially emerged were problems with two antennas (which then opened correctly) and with the infrared docking system at the International Space Station. These are solvable and not necessarily critical problems.
It will probably reenter about a week from now depending o.a. on developments in Space Weather.

Meanwhile, the #Proton-M rocket stage from the #Nauka launch is slowly coming down (most notably its apogee at the moment).
On the other hand, a problem that emerged later and concerning main engines (DKS) del Russian form Nauka. The module has two series of engines: those related to propulsion to reach the correct orbit for docking at the ISS and those (DPS / DTS) for maneuvers once docked at the station (orbit correction, avoid objects).
Since the module is no longer locked to any stage of the Proton-M rocket, it has to rely on its own motor DKS to reach orbit. An indiscretion had reported possible problems to the latter that could have caused the failure of the mission.
The first orbital correction took place at 5:07 pm yesterday and a subsequent one was made at 7:19 pm. However, we did not know if DKS or DPS / DTS engines (as backup) were used. My source confirmed that the firing of the DKS engines of #Nauka today was successful.
stated that it would be i motor DKS, as scheduled.

Roscosmos he added that there will be further orbital corrections today. Meanwhile, a meeting was also held, attended by Dmitry Rogozin, for a review of the functionality of the Russian form Nauka. During this session it could also have been defined that the Pirs module will be separated from the ISS together with the Progress MS-16 spacecraft no longer today, but tomorrow. The motivation for moving the undocking could always be linked to the need to be sure that Nauka can actually reach the ISS, otherwise the secondment will not proceed.
