Orbital grace of virtuoso "Science". Fresh borscht and eco-oxygen are on the way

"The science"

On July 29, 2021, the multipurpose laboratory module Nauka docked to the International Space Station - to the docking port of the Zvezda service module.

This exciting event was broadcast live. In the process of docking, the twenty-ton machine automatically performed a masterly maneuver around the ISS and, maneuvering between the solar panels and the ISS blocks, gracefully docked to the Zvezda service module. The docking speed in the final section was 10 cm / s.

MLM Nauka is a multipurpose laboratory module for the Russian segment of the International Space Station. It will ensure the implementation of the scientific research program in the interests of fundamental science, social sphere, development and augmentation of the resources of the Russian segment of the ISS.

Module purpose:

- ensuring docking of the Progress MS transport cargo spacecraft, the Soyuz MS transport manned spacecraft and the Prichal nodal module;

- roll control of the International Space Station;

- receiving fuel from the Progress MS cargo spacecraft, storing it and transferring it to the tanks of the Zvezda module for performing dynamic operations - correcting the ISS orbit, attitude and stabilization;

- storage of cargo delivered in the interests of the Russian segment of the ISS;

- ensuring the functioning of the European manipulator ERA;

- functioning of a complex of target loads for the implementation of the program of scientific and applied research in conditions of increased comfort of the crew;

- oxygen production to meet the needs of a crew of up to six people;

- functioning of the airlock for working with target loads, including using the European Robotic Arm robotic arm;

- functioning of the on-board workshop and a cabin for the third crew member of the Russian segment of the ISS, as well as ensuring the operation of a sanitation and sanitation device with a system for regenerating water from urine.

The main characteristics of the module:

Mass in orbit: 20 350 kg
Body length: 13,12 m
Maximum diameter: 4,25 m
Volume of sealed compartments: 70 cubic meters m
Photovoltaic cell area: 56 sq. m
Power supply power: 2,5 kW
Estimated duration of operation in orbit: 15 years
Working orbit altitude: 410-460 km

Experiments

Let's take a look at the list of experiments planned for the Science module.

- "Mirage", "Fullerene" and "Vampire" in the direction of "space materials science".

In particular, the experiment "Vampire" involves growing crystals from a molten metal in a furnace with a rotating magnetic field to further obtain substrates from which sensors of ionizing radiation of increased characteristics will be produced, including infrared sensors that can be used at room temperature.

- "Drop-2" in the direction of "space technologies".

This experiment continues a series of experiments on the development of a drip cooler-radiator for advanced spacecraft with a nuclear power plant.

As you know from the latest provided data, which were allowed to be made public, on the basis of the Nuklon ROC several projects of space platforms were developed: TEM (transport and energy module, in common people - the space "Tug") and "Zeus" - a machine twice more powerful and larger than the "Tug", with already partially pre-installed base payload.

Both there, and there, for cooling, steel radiators were designed, consisting of blocks of radiator panels with connecting bellows, through which the cooled gas will flow. But a drip refrigerator has a clear advantage - invulnerability to external influences (micrometeorites and other hostile objects and radiation).

So the intrigue remains: a drop or steel - time will tell.

The development of a preliminary design for a future space platform with a nuclear power plant is calculated until 2024, in accordance with the previously adopted and executed space program 2016–2025. And the first launch of a promising spacecraft, which will determine the future of human cosmonautics for the next century or two or three, is scheduled for 2028-2030.

The proposed appearance of the spacecraft with drop cooling

- "Head-miniRSA" - in the direction of "advanced space technologies".
Expected results:

- a promising technology for the manufacture of airborne AESA for SAR and, as a consequence, an onboard complex of a small-sized radar with a synthetic aperture, as a possible prototype of promising high-resolution radar systems for remote sensing of the Earth (and not only), used to solve problems of nature management, environmental control and monitoring of emergencies;

- improved methods for highly accurate determination of local relative displacements of areas of the earth's surface caused by deep seismic processes, as well as obtaining radar images, accumulating them and creating on their basis a databank (detailed radar portraits of natural objects).

And this already, if you look closely, when combined with the free electrical power of the space "Tug", launched even just into the Earth's orbit, opens up new horizons in the literal sense of the word.

- "Impulse" (2nd stage) - in the direction of "Solar system".

Development of a more advanced pulsed plasma injector is planned.

One of the tasks posed is to assess the effect of plasma emissions from the ISS PC on the development of geophysical processes: precipitation of particles from the Earth's radiation belts, disturbances in the geomagnetic field, and assessment of disturbances in the parameters of the environment and the electromagnetic environment in the near zone.

- "Quail" - in the direction of "space biology and physiology".

The expected results will make it possible to create a life support system for spacecraft crews during ultra-long interplanetary space flights, in which quails will become one of the main links of the artificial space ecosystem.

The novelty of the experiment lies in the fact that research into the embryonic development of the Japanese quail will be carried out under conditions of microgravity and artificial gravity created by the flight equipment of the experiment on board the ISS RS.

Previous experiments on the Mir OS showed the possibility of developing a living organism from eggs delivered from the Earth. However, the reasons that cause disturbances in the development of the embryo have not been established.

In addition, Japanese quail chicks were bred on board the Mir spacecraft, which could not independently adapt to the conditions of weightlessness. Studies of the embryonic development of Japanese quail under zero gravity on board the ISS RS using a new design of an incubator should answer these questions.

- "Capture-E" - in the direction of "advanced space technologies".

The purpose of this experiment will be to test the functioning of unified mechatronic modules for robotic systems for space purposes as part of SMS on the outer surface of the ISS RS.

We can safely assume that this technology will be used on all modules of the new Russian space station ROSS - after all, ambitious plans are laid on it, and the first letter "C" in the abbreviation ROSS means service.

ROSS will receive fuel from the Earth and refuel incoming spacecraft for various purposes, including the aforementioned Tugs. Well, no one canceled the man in the earflaps and with a sledgehammer from the feature film "Armageddon" - all of a sudden there will be something to patch up, and the mechruks will not reach.

Maintenance of uninhabited spacecraft in space is a pleasure for the elite. According to the latest data, only Americans with the world's most expensive space system, the Space Shuttle, were able to do this on an industrial scale when they launched to Hubble and other satellites for service. The launch of one Shuttle based on the results of a 30-year program (from open sources) cost taxpayers $ 800 million.

As you can see, the difference is in the systems: "expensive-rich-fly up" versus "cheap-angry-fly up".

Let's see and compare in action in the next 10-15 years.

- "Mutation" - in the direction of "space biology and physiology".

Influence of space flight factors on the mutation process, genetic exchange and regulation of antibiotic production in microorganisms.

- "Vitacyc-T" - in the direction of "space biology and physiology".

The results will be used to create an onboard conveyor space greenhouse for the ISS RS with reversible water supply and increased productivity, and later - a link of higher plants of biotechnical life support systems for crews in interplanetary space expeditions.

Сonclusion

So, what can you say about the results of considering the planned programs?

Serve fresh eco-oxygen with borscht here!

The entire scientific and engineering elite of the country looks with hope at "Science".

"Science" - full speed ahead!

Articles about Science, interesting, or it's all gone! Or everything is fine!

[military_cat]

They write that Science has not turned the ISS by 45 degrees (this figure slipped through in the negotiations broadcast by NASA), but by one and a half turns. NASA Flight Director Zebulon Scoville confirmed this to the people who were recording the transmitted telemetry.

When a Russian orbital service station appears, where, of course, it would not occur to anyone to broadcast telemetry and negotiations to the public, all articles will be just like that.

[ultra]

We docked in the machine, watch the video of the docking carefully. "Telepatch" on the correction engines is generally as possible. Do you have some kind of know-how? This of course does not cancel all the problems that were in the manufacture of the long-suffering "science" and after it was put into low orbit, well, turning on the engines after docking.

[Dmitry Vladimirovich]

Quote: ultra

To telepathically "on correction engines is generally as possible. Do you have some kind of know-how?"

For those who do not know how to compare the running time of the engines:

It is possible to check which engines were used to raise the MLM orbit by comparing the data on the results of their operation. To do this, you need to remember how MLM's “brother”, FGB “Zarya”, raised its orbit, the mass of which after launch was almost exactly equal to the mass of “Nauka”: 20302 kilograms for MLM versus 20265 for “Zarya”.

Zarya's voyage to the ISS orbit was described in detail in the Cosmonautics News magazine, 1 issue 1999. Then NK wrote that only one of a pair of DKS engines was used to raise the orbit.

The first test firing of the DKS engine No. 37 on the 16th orbit lasted 10 seconds, and a speed increase of 2,05 meters per second was achieved.

The second turn on took place at the 17th orbit. Then the engine ran for 100,9 seconds and provided an increase in speed 10 times more - 20,5 meters per second. The third turn on every other day lasted 31,58 seconds (speed increment 6,5 meters per second, the fourth - 116,44 seconds (increment 24,03 meters per second).

Thus, one second of the BCS operation gave the FGB a speed increment of about 0,205 meters per second.

According to Roscosmos, on the evening of July 22, the MLM engines would be turned on twice: at 18:07 and at 20:19. The first impulse lasted 17,23 seconds, while the speed increased by 1 meter per second. The second switching on of the engines lasted 250,04 seconds, and the speed increase was 14,59 meters per second.

That is, one second of operation of these unnamed engines gave the MLM a speed increase of 0,05 meters per second. A second of operation of the booster station, as we saw above, gives a significantly greater increase in speed - 0,2 meters per second.

From this we can conclude that other, less powerful engines were operating on board the MLM. These were probably DPS engines.

and turned the station on a roll, the roll had to be worked out by counter-rotation - turning on the engines of the Progress transport ship - how much fuel was lost useless?
That the Russian crew had to "move" to the American module - the emergency, it was not known what to expect from the "rebellious Science.

Dmitry Vladimirovich, keep your tantrums to yourself. Science was docked in an automatic mode, and not in a "manual" one. Nobody moved to the American segment. The station turned in pitch, not roll. Corrected the position of the station using Progress and Zvezda. However, we do this regularly. Because neither EKA, nor NASA, nor the Japanese can do this. As well as launching 20-ton modules into orbit. The last launch of a much lighter European ATV (10 tons) cost them $ 0.5 billion. in 2014. It was declared ruinous and they did not twitch anymore.
We have not launched modules for the ISS since 2010. Many competencies had to be restored anew. In November, we will consolidate our success by launching Pirs. So we have reasons to be happy. And you?

[Dmitry Vladimirovich]

Quote: Brancodd

So we have reasons to be happy.

At 12:34 pm EDT / 16:34 UTC, the ISS systems recorded a deviation from the nominal orientation. The station's gyroscopes tried to correct the orientation error, but failed.

At 12:42 pm ET / 16:42 UTC, the ISS orientation deviation exceeded limits and a loss of orientation emergency was declared, giving NASA and the ISS top priority via the TDRS (Tracking and Data Relaying Satellite) communications network ) in geostationary orbit.

At this time, the ISS was commanded to drift freely, the gyroscopes were turned off, and emergency control was transferred to the Russian segment and the Zvezda service module. Zvezda also tried to correct the orientation of the station, battling Nauka as the new module continued to start the engines.
For the next 45 minutes, Russian dispatchers tried to stop the Nauka engines from starting without a command. During this time, the vertical movement of the ISS never exceeded 0,5 degrees per minute, and the crew did not feel this movement.

According to Russian media reports, Nauka burned the remaining fuel during these thrusters.

At 13:29 EDT / 17:29 UTC, when Nauka's engines were no longer running, Russian controllers were able to use Progress MS-17 engines to return the Station to orientation mode and return to stable orientation.

That is, for the uninformed, the SCIENCE engines were turned off, but again the start command passed, the engines stopped spontaneously starting only after the full fuel consumption in the tanks of the SCIENCE module (!)
Is this a manifestation of competence?

ABOUT HOW !!! Actually, there is a little more fuel in the tanks than the service life of the engines ... After all the adventures, the fuel system had to be purged. And if the engines of "Science" at least five times gave out a random impulse, we would have lost the station ... God forbid. May the ISS guard NASA's longtime mascot, the Harter-Hightway Dragon

Science docked in automatic mode, not in "manual"

During the rendezvous, Nauka "lay down" on the maximum deviation of the rendezvous alignment and Soloviev ordered the cosmonauts to get ready to switch to manual rendezvous. 10 meters before joining. The cosmonaut had already put his hands on the levers of the TORU, but at that moment the automatics worked and Soloviev canceled the order.

And yes, here's a tip: don't give advice when asked ..

[Cosm22]

1. In what mode the docking took place is difficult to understand. Especially from the explanations of Roskosmos. The machine gun - TORU - is incomprehensible even from the available telemetry. The command to withdraw the module after docking passed, did not pass - it was covered in darkness. And the silence of the RK. Conflicting statements by Solovyov and Rogozin about a software malfunction and a human factor only reinforce suspicions. Okay, there is nothing secret that would not be revealed. Let's wait.
2. Speaking about the correction of the station, it would be nice to add: abnormal. Some people called the situation an emergency at all. The unexpected external impulse had to be extinguished urgently. We will find out about the unplanned fuel consumption very soon by the start date of the truck.
3. The orientation of the station is regularly changed by the gyrodynamics of the American segment. Orbit correction by thrusters is performed less frequently.
4. "Pier" rests on the ocean floor. The launch of the UM "Prichal" is planned for November.

Have you seen the video of the docking?
Sincerely

[Cosm22]

Saw. And from what I saw on TLE, I draw a conclusion about the machine.
And the words "hard to understand" refer to the few explanations and excuses of the RK. They are sometimes not only difficult to understand, but generally impossible.

[nobody75]

Why do you need their "excuses" - everything is on the video ...
Sincerely

[Beringovsky]

You shouldn't be like that. All the same, the module is very large, the withdrawal and docking of this with the ISS is a very difficult matter, taking into account that there has been no experience in the withdrawal and docking of objects of this scale in recent years. Why are there years, a decade. Yes, an unpleasant incident happened, but it is not worth sprinkling ashes on the head because of this.
This is not Colombia.

[Dmitry Vladimirovich]

Quote: Beringovsky

Yes, an unpleasant incident happened,

If this "unpleasant emergency" happened in unmanned mode, it might not be worth mentioning.
But the spontaneous activation of engines on manned spacecraft is no longer just an emergency (a prerequisite for a flight accident).

After successfully docking with the station, about three hours later at 12:45 EDT / 16:45 UTC, when the astronauts opened the Zvezda hatch to Science, the new module suddenly started the engines without a command.

This caused the ISS to leave its nominal orientation and eventually deviate 45 degrees (in fact, 1.5 revolutions).

Russian mission controllers discovered the problem, and Zvezda fired its own engines to try and fix the problem. However, Nauka's engines continued to turn on erroneously, and the two modules, in fact, fought with each other: Nauka changed the position of the ISS, and Zvezda tried, but could not completely correct this.

[Beringovsky]

Yes, this is clearly a jamb, they say that the programmers messed up. If so, then there is something to think about, and it would be necessary to ask questions to someone
There were a lot of such "jambs", it leads to unpleasant reflections ...

From the moment of docking to a manned spacecraft - an object, the safety requirements for it apply the same as for a manned spacecraft.
He sent a manned object into a somersault?
Exceeding the rotation speed and moment of inertia will tear the station apart, rip massive modules from the docking ports.
Is it easier to explain? A very "long" lever, very large masses at its ends.
Do you know why exercise bikes at the station are hung on stabilized platforms (not rigidly connected to the station's body)? Because the rotation of the pedals by the astronaut causes the oscillation of the masts of solar batteries up to half a meter in amplitude at the maximum departure, which can damage it

And then spinning the station by 1.5 turns.
It's just that none of the townsfolk understands how the situation was one step away from disaster.
From the fact that the masts of solar cells will begin to break, to the deformation of the docking nodes from centripetal accelerations.

Quote: Dmitry Vladimirovich

the situation was on the verge of disaster

Are you not overly dramatizing the situation? The angular velocity did not exceed half a degree per second, on average less than 0,3 degrees per second. In addition, the station is played regularly and often. Gyrodines, by the way, are also regularly unloaded, and there the thrust will be more serious in comparison with DPO "Science".

Do not worry, emergency accidents, like flight accidents, did not happen.
WASHINGTON, Aug 3 - RIA Novosti. The head of NASA, Bill Nelson, said that the joining of the Russian module "Science" to the International Space Station would contribute to the development of cooperation between the Russian Federation and the United States and promises prospects for new discoveries.
“The successful addition of a multipurpose laboratory module will further our collaboration with the Russians. I am thrilled with what the future holds for us - Nauka and the European robotic arm will help us make even more discoveries that are valuable both for life on Earth and for our progress in space and Mars, "Nelson said at a conference on the operation of the ISS. He added that last week, the space agencies of both countries had to endure "a bit of unplanned excitement" when, during docking, the engines of Nauka unexpectedly turned on. In direct interaction with each other, Russian and US specialists were able to quickly restore the ISS's orientation and ensure the safety of the crew, Nelson said.

Thirdly, why did you decide that the engines were running until they ran out of fuel?
Fourthly, how were you going to "cut off" the bugs (if any) during the tests in conditions when the flight sequence was not provided for in the plan?
Sincerely

In 20 minutes live!
Will answer all questions of space, the Universe and everything in general! Our universal favorite and famous visionary - the seer - Dmitry Konanykhin! He will tell everything - even where the bolt comes from, where he sailed and why

Start at 21-00!

[nobody75]

Krikalev has already told everything ... But Zelensky is nicer to you ...
Sincerely

[Mityay65]

I prefer the diversity of opinions.
I do not appreciate the work of Mr. Konanykhin, aka "Macaroni Monster", on YouTube, but I think that all opinions have a right to exist. If you don't like it, don't look.
The famous series of articles "Elon Musk's Macaroni Monster" delivered me incredibly! Although she is insane, she was just like a fresh wind in a dark kingdom
PS Well, what can we do, we don't have Scott Manley. And there is something that is and we live with it ... In this reality, Konanykhin is the best. "Times do not choose, they live and die in them"

[nobody75]

A variety of opinions is good. Especially if any opinion can be "how to change the market." It's just that I don't quite understand your colleague's opinion. Who called for the return of the "old testers" from retirement fishing. They already did this ... Boys and girls at first just made fun of the old people, and then they started sending them ... I had to give the "girls" spinning and send it back under the apple tree ...

I don’t have information on what is happening in the space industry, not my topic, however, 7 years ago or even more, I came across an article about the activities of the then new director of NPO Lavochkin. It wrote that he forced to resign all department heads over 45 years old, removing them from their posts. He liquidated the department that was engaged in software testing, which he himself had previously directed. As a result, young programmers connected to the rocket, which was already being prepared for launch, and controlled something right from the laptop. The article argued that a significant part of the problems with space launches and deorbiting are associated with the activities of this particular director and the lack of control over software development.
Are you not one of those young programmers?

[nobody75]

Purely by chance - no. I am not a tester. I am a developer. Do you believe that something can be edited directly from a laptop in a rocket btsvm? Although ... my favorite "Omen" compiles smartly ...
Sincerely

[Sergey Aleksandrovich]

I can quite believe that a sabotage comparable to sabotage has taken place, getting rid of experienced engineers and managers by age. And the subtleties of the procedure for making changes to the missile control unit somehow do not interest me. Even if they do it over WiFi, what difference does it make to me.
But you undertake to draw conclusions of the universal size about the unsuitability of age frames, the universal size of stupidity.
And your reasoning about the arrangement of checkpoints horrified me, at first I thought that this is the level of training in the modern army. But I see that I was worried in vain, the absolute nonsense about mining and other engineering arrangements, the capabilities of the BMP-2 and so on, is borne by a programmer, not a serviceman. So, for your information, some problems in hitting moving targets from a coaxial machine gun can arise at ranges exceeding 600 m, when the tracers go out and it becomes a little more difficult to adjust the fire, and there will be no chances to survive in a car under fire.

[nobody75]

Don't worry! Mine the desert within a kilometer radius from the checkpoint. By the way, I didn't write anything about mining - it's yours. Why did you not so loudly in the 90s resent the arrangement of the "quiet outpost" of the Moscow frontier detachment? Where were your "two tanks"? And how many BMPs were there? How did howitzer artillery help in defense?

some problems in hitting moving targets from a coaxial machine gun can arise at ranges exceeding 600 m, when the tracers go out and it becomes a little more difficult to adjust the fire, and there will be no chances to survive in a car under fire.

You made me laugh !!! 12,7 machine gun in the Turkish module, which I wrote about, is not coaxial !!! And to it is a laser rangefinder with a computer control system. Nobody needs your tracers. Perhaps crippling soldiers and setting fire to unarmored equipment ...
About the capabilities of the BMP - 2 and the inability to survive in a car under fire ... It's not funny already! While you were composing your empty post, the Taliban captured Kunduz on the Hammers and "carts" handed over to them by the Americans. I remember Mr. Staver had high hopes for the Northern Alliance, and now General Lapin has turned into a "Flemish boy" who is trying to plug a hole in the dam with his finger. I repeat once again - do not worry, your invaluable experience in squandering troops on company strongpoints will soon be in demand! You have to portray the activity before the flood ...
The current situation reminds me of the war between Khorezm and Genghis Khan. The last check was also a fan of "strongpoints" with "two tanks, three infantry fighting vehicles and ... five elephants." Remember how this war ended?

Quote: Dmitry Vladimirovich

Isn't that why we weren't invited to the Lunar Orbital Platform-Gateway project - competencies below the plinth.

There were proposals from NASSA, Roscosmos did not agree with the conditions, the Americans will still return to the conversation with Roscosmos on the lunar program.

Quote: Dmitry Vladimirovich

There are too many officials - and no one responsible for the international shame.

There is no shame, Science is docked to the ISS, astronauts are mastering the module.

Quote: Dmitry Vladimirovich

that there will be no parsing of the emergency ..

Here's an emergency.

Boeing CST-100 Starliner is a manned spacecraft that is being developed for flights to the ISS. On December 20, the ship without a crew set off on its first space flight. A day later, he was supposed to make an automatic docking with the ISS, and after a while return to Earth. The spacecraft was unable to enter the calculated orbit due to the fact that the spacecraft's engines did not give out the calculated impulse. As a result, it will not fly to the ISS, and on Sunday there will be a controlled descent from orbit. The ship should land at a training ground in the state of New Mexico.

Shame, competence below the baseboard.

[Knell wardenheart]

Thanks for describing the experiments. I haven't seen the full list before.

[Artyom Karagodin]

Yes, against the background of Roman Skomorokhov's publication in the next section, this one looks much more convincing. It can be seen that the person tried to delve into the topic, and not just express an opinion about it. The novel, alas, often sins with this.

[NDR-791]

I, too, are all in thought as not a special one even once. In the morning they dabbled in Science, praised it for dinner ... Where should the peasant go? (C) Yes, and by the way, the list of experiments may not be complete. More jobs are announced.

[Artyom Karagodin]

Quote: NDR-791

by the way, the list of experiments may not be complete

He at least is, but Roman only says that

The only experiments that are not surprising are the work on growing crystals.

One gets the impression that he either did not read this list at all, or "passed", as they say at school. But skepticism, as usual, with buckets. Roman is surprised that technologies will be developed there, for example, a drip refrigerator-emitter for Nuclon? So Roman's immersion in the subject is rather surprising.

[NDR-791]

Well, in the comments, someone voiced a small part. Here, however, more, but I think not all. Our module, not general, it seems. Americans do not let us into their specials. now we won't let it in.

[Brancodd]

One gets the impression that he either did not read this list at all, or "passed"

Everything is simpler. He prefers not to "go deep" in any topic. But the conclusion is always the same - "this regime is not capable of creating anything ..." It seems convincing to itself, but in reality it is tongue-tied and hysterical.

[Artyom Karagodin]

Quote: Brancodd

Perhaps I will agree ... True, in addition to "this regime" there is also "our people" and "our science", which are capable of much, I do not remember. The fact that all this often cannot be used competently is another question.

Regarding the nuclear tug, the author needs to follow the news more closely. It has an initial concept, now the device has a fundamentally different design. Well, at this stage, it was decided to abandon drip cooling, there are big technical problems with its implementation.

Did they put on the facsimile or "confirmed" in secret? Can you give a list of "numerous" problems? Maybe they were solved long ago in the package that was developed at Phystech?

In the end, you still need your own, independent RCS, Expensive but angry, if God forbid tomorrow is a war, then the cosmonauts, astronauts and teikunauts will sit together and look like little gods on the burning Earth? Or will they still cling to each other's throats, taking control of the ISS (there are probably such instructions), as the military personnel of potential and at the time of the conflict and real warring parties?

[tralflot1832]

Denis, thanks for the article, how much we discuss the Science module, but not from the scientific side. In the sense that Science can, and what we will have in the future. The experiment Drop 2 intrigued. I myself have been working "in the cold" all my life. We will search.

[Ross xnumx]

It's nice to read articles about the triumph of the ideas of Russian science. One listing of the module's components causes pride and respect for those who designed and created it. I kneel before the genius of scientists and designers and the painstaking work of installation specialists!

To the author personally!
That the titles of the articles (not necessarily yours), that individual phrases simply cut the sight and hearing:

Whole scientific and engineering elite country looks with hope at "Science".

Beau monde - to know, aristocracy, high society.

So, the geniuses of science or the aristocracy?
There was a TV program "Beaumond" with "beau monde". Comparing scientists and engineers to this ... is ugly.

[Disant]

So, the geniuses of science or the aristocracy?

geniuses of science - does not sound. Like something covered with an old blanket.
The engineering aristocracy, that is, in power, in power, with influence (without tying the word to any class structure of society!) - why not?
But people from science are not money-grubbing, therefore, at the same time "scientific and engineering aristocracy" is very controversial.
Therefore, the beau monde is a broader concept, as I see it.
in general, then you just need to decide on the terms and censor some words, for example, "elite", "blue", "dear Russians" - perverted to the point of disgrace - and now it is difficult to do what - associations are firmly attached to new, by no means positive, images

Victory always has many fathers, but defeat as an orphan is so

Thank you for responding to my extremely laconic comment.

It was not even in my mind to teach you how to write articles. Moreover, I do not write them, and you are good at it.

It just seems to me that to write, for example, at the end of the article "When writing materials from sites were used ..." - to show elementary respect for those whose work you used in your work.

Best regards, "crash".

And who prevented all this from being done at the ROSS station? Away from friends who sometimes drill walls? Judging by the open topic, promising research is being carried out there. And the closed ones? How will we protect them?

[Vadim237]

Time - you will wait 5-7 years according to ROSS build wait no need to carry out experiments now abroad on the spot the same do not sit especially Musk with his office only recently talked about the Superhavey rocket and now it with 29 engines is being tested

Dear author! Antonov Denis, aka Disant.
Why did you delete Dmitry Vladimirovich's post yesterday, the headline post of the thread? This post is the beginning of an interesting discussion that aroused keen interest and response from readers - paper-mailers
I read it, I really liked it, I wanted to repost to a couple of drinking companions, tk. there our misfortune (general) is succinctly stated ... But while I was chatting with them on the phone, the post disappeared ...
What happened there?
Is there something we don't know? Can't talk about it now?

[Dmitry Vladimirovich]

Quote: Mityai65

You can't talk about it now

Probably Denis expected only delight.
His other task is to promote "success".
Overly competent people - they begin to ask uncomfortable questions, it is easier to curtail the discussion, radically :)
Admitting your mistakes, conducting open disputes - apparently not that era.

This is how Boris Chertok (one of the first Chiefs who does not know) describes the reason for the loss of DOS-1

finally, the side arms may break. There was a very strong side roll right after the capture.

- Why pitching? Where are the speakers? Rauschenbach! Why were there hesitations? - Mishin demands an answer.

An unpleasant thought struck me. I asked Pavel Popovich, who was in direct contact with Granit:

- Inquire "Granite", what were the vibrations during pulling?

- No need to ask. Eliseev reported that after the "capture" the "Nozzles DPO" transporter lit up and blinked for 30 seconds. At this time, the ship was swinging strongly.

I realized that further interrogations of the dockers would not yield anything, and after consulting with Rauschenbach and Tregub, I laid out my version of what had happened to Mishin and Kerimov:

- Most likely, mechanical failure has occurred due to large lateral vibrations. We did not turn off the control system. Immediately, as soon as the touch occurred, the disturbance passed, which the angular velocity sensors tracked. The control system tried to remove angular deviations, but the "capture" had already taken place, instead of calming down, swaying began, but not around the center of mass, but on the bar, which engaged the DOS in the receiving socket. We broke something. It is useless to continue trying to dock. It is necessary to make a decision on undocking.

Boris Chertok - Rockets and people.
http://militera.lib.ru/explo/chertok_be/34.html

In total, they did not provide for the shutdown of the automatic orientation system of the Union, which is why the first DOS was lost.
And then - the first DOS was put into orbit in a regular way, which the "grandchildren" could not repeat.

[Disant]

His other task is to promote "success".

The end result is success, so that someone does not come up with this fact.
about "tasks" and "manuals" - it's not for me.

[dub0vitsky]

Quote: Vadim237

Time - you will wait 5-7 years according to ROSS

You need to figure it out first, which is more important. And then put ahead. Throw away illiquid assets that have lain for an entire epoch on Earth, reworked many times, spend a couple of tens of billions more on this, or accelerate the launch of Ross, having a block ready for usefulness, supplementing, working, saving those same grandmothers for launching unnecessary ones? Or for Ross such a piece of iron is no longer necessary, it became clear that they had done crap? And if you did crap. then why waste money on starting crap? I don’t understand the current leadership of Roscosmos. Inexpressible stupidity, stupidity is based on stupidity, jumping from one idiocy to another. But the plans are GREAT. Not the management of a very expensive industry, but hysteria. Isn't it time to stop this business. putting there a purposeful, calm, and cruel person in his decisions?

[Vadim237]

What the hell did the ISS do here? NASA decided to extend the new ROSS station in 2030, it will cost a hundred billion if not more, and Science is already in orbit and the first ROSS module starts working only in 2025 will the budget for space fly, we have no rubber so that there would be headlong acceleration in case then Science can be undocked with the help of the same Progress and docked to a new station - and it is not Roscosmos that needs to calm down, but you.

[dub0vitsky]

Let NASA rack its brains. And we need to leave, they themselves say that after 2024 the operation will become emergency. Remove your blocks after 24 years, and drown them. Let's see how the rest of the time the Americans will correct and manage this rubbish. You need to leave five minutes early. than one minute later. What agreement did we have with them? Until what year? Completed completely? It will no longer be possible to earn money on a cab. That is, the income is zero, the costs for what? In the name of constant repairs and the risk of crap, Zvezda is already draining the atmosphere seriously. What the hell is a transition block, open it, lose air. And the hole cannot be found. To be honest, it will be right to leave. Do not spend money on reanimation of trash. Let them go, Ross do. Or, to return the reliability, the Star to the ocean, and instead of it, Pierce. Losing volume? Maybe. Or do we want to disconnect and lower this entire structure in an emergency? Are we not afraid? Then we will not wash off.
It is much better to leave this happiness to the American partners.

Here on the Archive Revolution it is less enthusiastic and honest about the Science module.
Mihail Cats. Risky flight of "Science"
I am always amazed how one and the same information can be submitted. One for the crowd, the other for the really interested. It turns out that the Science module almost fell if they had not had time to raise its orbit using all possible engines for this. And the flying bolts there are trifles with the shavings that were cleaned there several times. years. Practice will show whether everything has been cleaned.
