Russian cosmonauts Novitsky and Dubrov made a spacewalk on the ISS

Russian cosmonauts Oleg Novitsky and Pyotr Dubrov made a spacewalk to carry out preparatory work to receive the new Science module. The release is broadcast on the official website of Roscosmos.

According to the state corporation, the opening of the exit hatch of the Poisk docking compartment took place at 08:53 Moscow time. In total, Russian cosmonauts will have to spend about 7 hours in open space. During this time, they must prepare the docking compartment for the arrival of the "Science" module, replace the removable panel of the fluid flow regulator, and install equipment for scientific experiments on the "Search" module.

After 14:00 Moscow time. time. it was reported that the astronauts replaced the panel on the Zarya module, packed it in a sealed container and sent it into outer space.

The Control Center explained that the spacewalk was the first for both Russian cosmonauts. It is performed in Russian Orlan-MKS spacesuits. Novitsky has red stripes on his spacesuit, and Dubrov has blue stripes. The work of cosmonauts on the surface of the ISS is supervised by specialists from the Main Operations Control Group, who are responsible for extravehicular activities.

Let us recall that the launch of the Nauka module to the ISS is scheduled for July 15 this year. The "Science" will be docked to the "Star" module. Despite its name, the new module will also be used to maintain the orientation of the ISS, dock ships and maintain the station's life support system. In addition, the module will have a living single cabin.

I remembered a joke (off-topic):

After Gagarin’s flight into space, a Jew comes to the passport office:
- Hello.
- Hello.
- I would still like to change my surname.
- What is your last name?
- Katzman.
- And what would you like? - Katzmanaut

Interestingly, but without an airtight container, this piece of iron could not be thrown out?

Maybe this container itself was waste and was also planned to be thrown away. For example, a new panel was packaged in it.

Well, so why create two space debris when you can create one?

Have you seen a US scout satellite flying from behind?

[Wedmak]

why create two objects of space debris

In general, it was necessary to pack all the garbage removed from the ISS into nets attached to the surface of the returned ships. Better transport, so as not to risk the crew. And everything will burn perfectly on return. There is no need to clog up the orbit of the station with unnecessary rubbish.

This is still to be discussed.
In the meantime, there is an opportunity to just laugh. Above, for example, such a pearl: "Despite its name, the new module will also be used to maintain the orientation of the ISS ..."
How interesting is the module to be able to change the orbital parameters or the orientation of the station? With your engines? Ruled out.
Possibility of fuel transit from a truck? Ruled out. After the glorious epic of fighting garbage in the bins, the product became disposable. The problem with the bellows is not resolved. Here, at least, the docking is somehow carried out.
There can be no more talk. No one will take the risk of connecting the module to the ISS TS.

Blizzard blizzard. First, the roll orientation of the station always support with the help of "Progress MS" remote control. Secondly, the pipelines for pumping fuel from Progress to the Zvezda CMDU pass the tanks of the remote control module. The "Science" module does not need a "reusable" use of its engines at all in principle... He retained this rudimentary function from the fact that he is the "twin brother" of the Zarya module, which spent two years alone in orbit waiting for the SM in the late 90s.

MLM-U Nauka's own engines are required only to fly to the ISS and dock the module with the station. Everything.

[Cosm22]

1. Is the meaning of the phrase "the module will also be used to maintain the ISS orientation" clear?
I think there should be. Even for a speaking training manual. It was to this absurdity that I drew attention. What does the "Progress MS" remote control have to do with it, if the article deals specifically with the Science module? Nothing to say? The advice is the same - it is better to remain silent.
2. Basically it was originally planned to integrate the TS of Science into the TS of the ISS. But since it was beyond the power of the RK to fix its jambs, such excuses appeared - "The" Science "module does not need a" reusable "use of its engines at all." Type green grapes.
And there is no need to mention well-known truths. Everyone knows very well that the Progress engines are usually used to correct the orbit or to perform additional maneuvering of the station. In addition, the trucks are connected to the vehicle of the Russian segment and part of the fuel is pumped to the FGB “Zarya”. So, due to the danger that the chips from the MLM tanks can cover the valves of this very vehicle with a copper basin, and the module has become a reusable one-time module. Just sleight of hand. And now once again I advise you to ponder (if possible) the meaning of the phrase "Despite its name, the new module will also be used to maintain the orientation of the ISS ..." How? None. It was into this delirium that I poked my nose. What's not clear?

Will be. Until the moment when "Progress MS" is attached to it.

Why, if you are grinding a blizzard.

And where it is written that it is not planned now - the fuel will be pumped as before.

Quote: Cosm22

there were such excuses - "The" Science "module does not need a" reusable "use of its engines at all."

What "caveats" if this is the case. The engines would be required if, as previously planned, the ISS was flooded in 2017. To create a station ROS.

FGB is a warehouse. Well, the fuel storage. His engines have not been working for a long time. MLM-U "Science" is not a warehouse - it is a scientific laboratory.

Quote: Cosm22

How so?

Yes, not in an image, but in something like a candle. The above is written.

[Blackmokona]

Maybe then just burn it along with the truck? Why create garbage at all, and even next to the ISS?

[Cosm22]

And money? Where is the money then, Zin?
Indeed, an insane amount of dough has already been spent on a quarter-century epic with Science-MLM. And if this whole story ends with a simple puff - who will be responsible for this? It is necessary to run.
Maybe even docking the module to the ISS by some miracle will succeed. Perhaps the engines will not fail and they will be enough at least for docking.
Well, in terms of experiments, with a successful docking, the opportunities for the Russian crew will increase. How long can you, figuratively speaking, stand in a humiliating line in the American or European segment for scientific work? The cat cried its own stands in the Russian segment. And here there may be such help. Like you say - the module is called scientific, with extended functionality.
Another thing is how long the ISS itself will last. Although the answer here is simple: exactly until there is a real clearing in the Artemis or Gateway projects. Or Musk Starship will confidently enter orbital, a lunar lander will appear in the hardware, or the HS / SS combination will work.
After that, it will be possible to put a bold cross on the ISS. NASA will not be interested in the project. Well, except that private traders will take care of it.

Is there a lot of space? Maybe it's better to reserve the volume for more pressing garbage?

Why create garbage at all, and even next to the ISS?

And who will he interfere with on the ISS? The relative speeds are low. If you push the debris back along the flight, then it will definitely never meet with the ISS again and each orbit will decrease by N millimeters and in 1-2 years will burn up in the atmosphere.

It will not interfere with the station. This container will very quickly go out of orbit and burn up.

[Soldatov V.]

It's time to end these toys with death, the ISS is about to fall apart, and sending a twenty-five-year-old module there is a crime. During this time on the earth, a lot of things rot and fall apart, and even more so in space.

[Other]

Yes, there will be a lot of work in space now, we need to hurry! If this year "Science" is not launched, then, in principle, it is no longer worth it, all the same it has already stood on the ground for the entire period of operation. But so that not entirely in disgrace, then as a robot Fedya - you need to run! Again, the mission that was launched towards Mars in 2019 should already be returning, it needs to be met in the orbit of the Moon.

I asked a specific question. Stop your addict clowning and deign to answer. When you sober up.

I asked a specific question.

Specific answer. The module was made in 2013. During the tests, it turned out that there was debris in the pipelines; when trying to flush, the debris got into the tanks, which could not be replaced promptly, since their production had already been discontinued. Russia did not intend to produce more modules of a similar design (FGB TKS) and began to produce a module of a completely new design.

The module was returned to the manufacturer (TsiH) for revision. It was not possible to immediately eliminate the defect with the tanks, and since 2015, the module has been temporarily placed in storage, from which it would have been removed in 2017, for subsequent revision. It was improved by replacing the old and installing new equipment - an external platform was also installed on the module for attaching scientific experimental installations.

Since 2020, the module has been delivered to Baikonur, where complex factory tests were carried out with it, which it passed successfully and, as a result, its immediate preparation for launch began. The European ERA manipulator was installed on the module. The manipulator will be used to work with the external airlock, which is waiting for the MLM-U "Nauka" module in orbit, attached to the MIM-1 "Rassvet" module.

Wrong. The American segment belongs to the USA, it includes the Japanese and European modules belonging to Japan and ESA, respectively. The United States also owns the Zarya FGB module of the Russian segment, 1/3 of the internal volume of which is used by Russia for its own needs under the Russian quota. The rest of the modules in the Russian segment are fully owned by Russia. Segment management is carried out respectively from Houston and Korolev.

[fa2998]

Everything that you wrote exactly confirms my words. The ISS does not belong to Russia entirely. Different parts belong to different countries. And if most of our "allies" decide to flood, I think Russian modules are unlikely to be saved.

In this case, most of our partners in the ISS will not have a station either, so they will not decide. At least until 2025. And then it will make no difference to us - we will launch NEM for ROSS.
