Module "Science" successfully docked with the ISS

16:29 29 July 2021

The Nauka multifunctional laboratory module has successfully docked with the Zvezda module of the ISS Russian Segment. After the launch, the module ran into technical problems, including malfunctions in the propulsion system, but Roscosmos specialists were able to fix them. As part of the ISS, the module will be used to conduct scientific experiments and ensure the operation of the station. The docking was broadcast on the YouTube channels of Roscosmos and NASA , as well as in our text online .

Nauka is the first new module of the ISS Russian Segment in 11 years. It was planned to launch back in 2007, but due to technical problems, the launch took place only in 2021. The main problem faced by engineers on Earth is metal shavings in the fuel system. It took more than one year to remove it, you can learn more about this from our material "Fatal shavings" . Small difficulties arose before the launch itself: the specialists forgot to close part of the equipment on the outer surface with screen-vacuum thermal insulation, so it had to be removed from under the head fairing and returned to the Baikonur assembly case.

The launch of "Science" took place on July 21, 2021. The very next day, the module in orbit had problems in the fuel system, so initially it could not turn on the engines. Later, Roskosmos was able to transfer the engines to normal mode and began to raise the module's orbit. Sources also reported problems in the Kurs automatic docking system, but they were also corrected before docking.

On July 29 at 16:30 Moscow time, after an eight-day flight, Nauka touched the docking port of the Zvezda module and the cosmonauts began the process of full coupling and retraction. The integration of the module into the ISS will not end there, and the astronauts will have to carry out ten more spacewalks in order to finally connect all communications, install a robo-arm made by ESA and carry out other work.

After the module becomes a full-fledged part of the station, it will help it maintain orientation, generate oxygen and water for the crew. The module will also be a place for scientific experiments, for example, with the creation of controlled gravity using a centrifuge. In addition, the module has a cabin for one person and a second toilet for the Russian segment.
The next big mission of Roscosmos is the launch of the first lunar lander Luna-25 since Soviet times. Until recently, it was assumed that he will go to the moon this year, but perhaps the flight will still be postponed to 2022.

Nauka/ISS: Russian flight controllers appear to be working an issue of some sort with the newly arrived Nauka lab module; thrusters are apparently firing on both the Nauka and the Russian Zvezda service module

View: https://twitter.com/cbs_spacenews/status/1420793721268867077


Nauka/ISS: NASA CAPCOM to crew: "Just to update you guys, right now we're in a little bit of a tug of war between thrusters firing from both the SM (service modeule) and the MLM (Nauka). We're sorting through the best course of action right now"

Good news from MCC Houston: Nauka thrusters are no longer firing. Attitude control appears to be stabilizing for the International Space Station.

It's not clear what happens next, or whether this affects the planned launch of Starliner on Friday afternoon from Florida. What we know from MCC Houston: "It’s safe to say the remainder of the day is no longer going to happen as scheduled."

They are going to purge Nauka’s fuel system with helium tomorrow. Also blow pyrovalves to seal it off so no containment’s can’t get into ISS from it. Both of these actions they were going to do anyway.

How much non-Nauka fuel did this cost, though? Plus they had to rotate the station for this docking because they were worried Nauka would blow an off-axis approach, and then put it back afterwards. What strange, concerning start to this module's life.

To answer your question via NSF:
During the teleconference, Montalbano said that he wasn't concerned about the amount of depleted prop due to this incident, though it was obviously more then typical it was not enough to worry about.

Well they put the MLM thruster off-line. So no more funny stuff. They will continue to prepare the MLM as earlier planned. Takes about 11 space walks before the module in a complete state.
At the same time Mission Ground Control will assign a comitee to find out what went wrong.
My guess its software driven.

Russian cosmonauts may temporarily move to the US segment of the ISS

06:59 07/30/2021 (updated: 09:41 07/30/2021)

MOSCOW, July 30 - RIA Novosti . On Friday, Russian cosmonauts at the International Space Station (ISS) may temporarily move to their "neighbors" so that specialists can bring the fuel system of the Nauka module to a safe state by purging the highways with helium.

This follows from the conversations of the crew with the Earth , broadcast by NASA . Cosmonaut Oleg Novitsky asked a specialist from the Mission Control Center near Moscow to coordinate such a possibility with his American colleagues.

The Nauka module docked to the ISS Zvezda module on July 29 after an eight-day flight. It was launched on a Proton-M rocket on July 21, but at the time of launching into orbit one of the ground stations could not receive information from it. After a successful docking with the ISS, when the crew opened the module hatch, the Nauka's engines turned on unscheduled. To stabilize the ISS, the engines of the Russian Progress spacecraft were also brought into working order, there was no threat to the crew.

NASA said that Russia will lead the investigation of the incident, and American engineers will also take part in it. Organization spokesman Joel Montalbano stressed that no damage was found during the docking.

Now the 65th expedition is working on the ISS, consisting of the Russians Oleg Novitsky and Peter Dubrov , the Americans Mark Vande Hai, Shane Kimbrow and Megan MacArthur, the Japanese Akihiko Hoshide and the Frenchman Tom Peske .

13:07 07/30/2021 (updated: 13:18 07/30/2021)

MOSCOW, July 30 - RIA Novosti. The hatch to the multipurpose laboratory module "Science" on the ISS is scheduled to open on Friday closer to nine in the evening, follows from the negotiations of the crew with the Earth, broadcast by NASA .

The opening of the hatch to the "Science" was postponed the day before due to the module's engines spontaneously turned on.

A specialist at the Houston Mission Control Center told ISS Commander Akihiko Hoshida that the opening of the hatch to the Nauka module is scheduled for 20.45 Moscow time.

On Friday morning, a specialist from the Moscow Region Mission Control Center allowed cosmonaut Oleg Novitsky to open the hatch of the Zvezda module leading to Nauka, the hatch of which is still closed.

Module "Science" docked to the ISS on July 29. Three hours later, the engines spontaneously turned on on it, which led to a turn of the station by 45 degrees. To return the ISS to the desired position in space, the engines of the Zvezda module and the Progress MS-17 cargo vehicle were used. There was no threat to the station's crew. At the same time, Roskosmos reported that Nauka was being integrated into the ISS and that work was being carried out with the remaining fuel in the module.

Now the 65th expedition is working on the ISS, consisting of the Russians Oleg Novitsky and Peter Dubrov, the Americans Mark Vande Hai, Shane Kimbrow and Megan MacArthur, the Japanese Akihiko Hoshide and the Frenchman Tom Peske.

It seems not. See below.

MOSCOW, July 30 / Radio Sputnik . Roscosmos has no plans to investigate the situation with the Nauka module on the International Space Station (ISS), RIA Novosti reports, citing a source in the rocket and space industry.

Earlier, the head of the ISS program at NASA, Joel Montalbano, said that the investigation of the incident would be led by a Russian state corporation with the participation of American engineers.

“Roscosmos is surprised by the reaction of the Americans to the peculiarities of the docking of the Nauka module with the ISS. No commissions on this issue, especially with NASA engineers, will be created, the situation is accepted as normal,” the agency's source said.

The day before, it was reported that the engines of the Nauka module, docked to the ISS on Thursday, unscheduled. To compensate for the indignation from the switched on Nauka engines, it was necessary to start the engines of the Zvezda service module and the Progress MS-17 cargo vehicle docked to the Poisk module.

Later, Nauka's engines were turned off.

On the eve of radio Sputnik reported how Roscosmos explained the inclusion of the engines of Nauka.

I prefer not to use RIA, RT or TASS(or any other news outlet)..

I got my news directly from the NASA Q & A very recently.

NASA clearly stated that the commity was SOLY a Russian Roscom initiative.. so i don't read the regular press.. its baaad

Vladimir Soloviev, the flight director of the Russian segment of the ISS, about the yesterday's #Nauka troubleshooting (a thread⤵️).

View: https://twitter.com/katlinegrey/status/1421069533008252932


Yesterday's approach of Nauka with the ISS went nominal, excluding some fluctuations at the last part of the travel, but the docking system could handle it.

View: http://twitter.com/katlinegrey/status/1421070107288260609


Due to a short-term software failure, a direct command was mistakenly sent to turn on the nauka's engines, which led to "some modification" of the orientation of the station.

View: https://twitter.com/katlinegrey/status/1421070930785275910


The propulsion system of the Zvezda Service Module quickly countered this situation. Now the altitude control of the station is regained, is in its normal orientation, all the systems of the ISS and Nauka are working normally.

The hatches between the module "Science" and the ISS are open

07/30/2021 20:48

On Thursday, July 29, 2021, at 16:29:06 Moscow time, the Nauka multipurpose laboratory module , launched on July 21, 2021 from the Baikonur cosmodrome, was docked to the International Space Station . Today at 20:47 Moscow time, Roscosmos cosmonauts Oleg Novitsky and Pyotr Dubrov opened the transfer hatches and boarded the new Russian module "Science".

After the completion of the docking operations of the multipurpose laboratory module with the nadir docking port of the Zvezda service module of the ISS Russian segment, specialists from the Moscow Region TsNIIMash Mission Control Center (part of the State Corporation Roscosmos), together with the crew of the ISS Russian segment, conducted a tightness control of the docking connections and analyzed telemetry information on the state of the module on-board systems. Then the Russian members of the ISS-65 Expedition Oleg Novitsky and Pyotr Dubrov opened the hatch of the transition compartment of the Zvezda module and a few minutes later entered the living area of the instrument-hermetic compartment of the laboratory module. In accordance with today's work plan, on board the multipurpose laboratory module, Roskosmos cosmonauts will perform a control examination of the compartments,

Nauka is a multipurpose laboratory module for the Russian segment of the International Space Station. It was created by a cooperation of enterprises with the leading role of the Rocket and Space Corporation Energia (Korolev, part of Roscosmos), as a module developer in order to implement a program of scientific experiments and expand the functionality of the Russian segment of the ISS. The module structure was manufactured by the State Space Research and Production Center named after M.V. Khrunicheva (Moscow, part of Roscosmos).

The multipurpose laboratory module "Science" is intended for the implementation of the Russian program of scientific and applied research and experiments. After its commissioning, the Russian segment of the station will receive additional volumes for the arrangement of workplaces and storage of goods, placement of equipment for the regeneration of water and oxygen. It consists of an instrument-hermetic compartment and a spherical pressurized adapter, separated by a sealed bulkhead with a hatch. It is also equipped with an airlock for carrying out scientific equipment outside the station and a European remote manipulator ERA (European Robotic Arm).

In the new Russian module, it is planned to conduct 13 experiments in various directions, including Kaplya-2 (space technologies), Aseptic (space biology and physiology), Mirage, Vampire, Fullerene (space materials science ), "Vitacyc-T" (space biology and physiology), "Rakurs" (exploration of the Earth from space) and others. Flight tests of the "Science" module will be completed in about a year.

Well, if the mercurial thrusters make the crew motion sick, they might end up looking like Kerbals...
