| | Robert Pearlman | Roscosmos release Specialists have worked out test corrections of the orbit of the Nauka moduleOn Thursday, July 22, 2021, the Nauka Multipurpose Module Flight Control Group specialists at Moscow Mission Control Center conducted two correction maneuvers of the module that had launched to the International Space Station the previous day. The first maneuver took place at 15:07 UTC with the module engines burn for 17.23 seconds giving an impulse of 1 m/sec. The second burn for 250.04 seconds took place at 17:19 UTC with an impulse of 14.59 m/sec. Orbit parameters after two burns: - Orbital period: 90.17 minutes;
- Orbit inclination: 51.64 degrees;
- Perigee altitude: 230.43 km;
- Apogee altitude: 364.86 km;
Thus, the telemetry confirmed the module propulsion unit operability. Additional burns for further orbit correction are scheduled for July 23. The Pirs module is to undock from the ISS and deorbit on Saturday, July 24. | | Robert Pearlman | Roscosmos release Mission Control Center conducted orbit corrections of the Nauka moduleOn Friday, July 23, the Nauka module flight control group specialists at the Mission Control Center conducted two correctional maneuvers of the module orbit that launched to the International Space Station on Wednesday. On Saturday, July 24, the Nauka Multipurpose Module flight control group specialists at TsNIIMash Mission Control Center (part of Roscosmos) conducted two more corrective maneuvers of the module. The next burns for further orbit formation are scheduled for July 27. | | Robert Pearlman | Roscosmos release Final Nauka module orbit correction conducted before docking with ISSOn Wednesday, July 28, 2021, specialists of the Nauka Multipurpose Laboratory Module flight control group at the TsNIIMash Mission Control Center (part of Roscosmos) performed the final corrective maneuver of the module which had launched nominally from the Baikonur Cosmodrome a week ago. The engines were fired at 13:43:07 UTC. According to telemetry information, the propulsion system of the module worked normally. No new orbit corrections are planned before the Nauka module docking with the Russian segment of the International Space Station, which is scheduled at 13:26 UTC (9:26 a.m. EDT) on July 29, 2021. Nauka is a multipurpose laboratory module for the Russian segment of the International Space Station. It was created by the cooperation of enterprises in order to implement the program of scientific experiments and expand the functionality of the Russian segment of the ISS. After its commissioning, the Russian segment will receive additional room for arranging workplaces and storing cargo, placing the water and oxygen regeneration equipment. | | Robert Pearlman | collectSPACE Russia's Nauka multi-purpose lab module docks to space stationThe International Space Station has gained a new room after a 13-year wait for its launch and a week-long journey in Earth orbit. Russia's Multi-purpose Laboratory Module (MLM), named "Nauka" ("Science" in Russian), docked to the space station on Thursday (July 29), eight days after its more-than-decade-long delayed launch. The 22-ton (20-tonne) MLM connected with the orbiting complex at 9:29 a.m. EDT (1329 GMT), using an open port that was recently vacated by the Pirs docking compartment on the Earth-facing side of the Zvezda service module.  | | Robert Pearlman | Roscosmos release Energia Designer General on MLM Nauka dockingVladimir Solovyov, Twice Hero of the Soviet Union, Pilot-Cosmonaut of the USSR, RSC Energia Designer General (part of Roscosmos), Flight Director of the Russian Segment of the International Space Station: "On July 29, the Nauka Multipurpose Laboratory Module was docked with the International Space Station. At all stages of the module's flight, its rendezvous system worked reliably and stably. During the final rendezvous, slight fluctuations were noticed, which were eliminated by the docking system. This resulted in smooth docking and touchdown at rated speeds, which in turn resulted in mechanical coupling. "The docking mechanics worked reliably, without any comments and led to the closure of both docking mechanisms of the station and the module. Due to a short-term software failure, a direct command was mistakenly implemented to turn on the module's engines for withdrawal, which led to some modification of the orientation of the complex as a whole. "This situation was quickly countered by the propulsion system of the Zvezda module. At the moment, the station is in its normal orientation, all the ISS and the multipurpose laboratory module systems are operating normally. A reliable internal power and command interface was created, as well as a power supply interface that connected the module to the station. "The crew is now busy balancing the pressure in the Nauka module. This is a rather lengthy procedure, because the total volume of the module is about 70 cubic meters. In the afternoon, the crew will open the hatches, enter the module, turn on the necessary means of purifying the atmosphere and begin normal regular work. The Chief Operating Control Group operates normally and manages the entire complex, including the Nauka module." | |
