The European Agency refused to use the Russian "Union-ST" to launch satellites

This year, the European Space Agency (ESA) will not use the Russian Soyuz-ST carrier to launch satellites of the Galileo navigation system - the spacecraft will launch their own heavy Ariane-5 missiles into orbit, reports Look with reference to the head of the agency Johann-Dietrich Werner.

Soyuz-ST in the Guiana Space Center

“This year we will launch the first Galileo satellites on Ariane-5,” said Dietrich.

“The Ariane-5 heavy-class carrier will be able to launch four Galileo spacecraft into orbit while the Europeans can only deliver two satellites at a time on board the Soyuzov,” explains the publication.

In December, Soyuz-ST put 11 and 12 satellites of the navigation system into orbit.

At the end of March, 2015 G, head of Arianespace Corporation, Stefan Israel, stated that the Russian rocket "did an excellent job with the task of putting Galileo satellites into orbit."

It is planned that a total of 2020 satellites will be placed into orbit by 30 g. The system developers claim that Galileo will be more accurate than its analogs, and “will provide Europeans with independence from the American GPS, the Russian GLONASS and the promising Chinese Compass”.

% bank loan rate (for working capital of the enterprise) there is 0% or NEGATIVE, we have from 18% per annum.

All of Europe is smaller than the RF RF, transport is ideal. we have?
Something in Moscow, something in St. Petersburg, something in the Urals, and something in Novosibirsk?
Gather it all, and then take it from 5000 km to the spaceport, by train.


2. Based on what and who made this conclusion?

The cost of ground services, and especially insurance, is not regularly taken into account, the cost of which can vary greatly depending on missile failure statistics. Russia does not take LCI into account at all (USSR costs for developing everything)

Vostok launch vehicle $1/kg In the early 90s, the cost of starting was only $ 7-8 million to attract foreign customers. Since 1991, decommissioned.

On March 7, 1988, the Vostok launch vehicle (earlier modification) was launched into orbit by the Indian IRS-1A Earth remote sensing satellite. Launch cost was $ 7.5 million

The launch of the IRS-1C on the Molniya-M rocket already cost $ 12.8 million.


the cost of one launch of the Vega launch vehicle NOW in the global market is from 35 to 45 million euros
Launch weight 137 kg = LEO, kg 000 - 1
As if yes, in comparison with "Soyuz-ST".
But how much does ESA earn (well, at least 80% profitability, or even all 150%) and TsSKB-Progress (in the red?)?

the end of our space program

It is said loudly, again corrupt officials, etc. One feels the hand or mouth of Bulk cakes ...
There was a time when they survived, even tourists had to be transported, but this time ended irrevocably, the main customer, the Ministry of Defense, is increasing the satellite constellation at an accelerated pace. And do not forget that in a manned space program there is one monopolist and this is the Russian Federation and the only manned carrier. There are also Chinese Tuikunauts in the same counterfeit Union, only repeating the flights of our first cosmonauts, a couple of turns and vice versa, without a rotational station, there is about a 60-year backlog. There is such an ISS project, there, in addition to a constantly-working crew, a bunch of modules, i.e. Russian, American, EU and even Japanese. It is now supplied only with Progress (after disasters with the Dragons, etc.) - an unmanned Union, and the pilots' shift, well, again we are. There are carriers in the EU, why didn’t they serve the EU group, it turned out to be unprofitable for the Unions and the dependence is critical because it is a dual-purpose group, after all. The EU also needs to show the results of joint public education, otherwise the EU is completely bursting at the seams due to the economic crisis and migrants. We need something vivid and memorable, albeit unprofitable, such as Concord, but before the first catastrophe, which, unlike NASA and the interference (the Shuttle death destroyed their manned space program, well, NASA’s critical dependence on our engines like Rd- 180 etc.) The European Space Agency will not survive.
And you immediately end. In Russia, the end is always the beginning of an even more grandiose, at least the last millennium, if there were less alarmists and traitors, it would be very good.

Yes, astronautics and the nuclear industry are still keeping abreast, as practice shows - until the first stool, that's the trouble. They multiply like cockroaches.

[hrych]

As they say, judge according to their deeds. The armed forces that we have now are created under Mr. Serdyukov, the first victorious war of New Russia, not only for control of the Greater Caucasus Mountain Range, no more, no less. The adoption of Yars, Mace and Iskander, etc. Shoigu is not a magician, when he came it was all created. We need a serious analysis of the situation. The army is now in perfect order with us, is it so stool, and what did he get in his time and in what condition (I’m talking about EBN).

[gunya]

Before praising the Fuhrer stool, think about it: when all the systems you listed were created. This is all Soviet development.
"The first victorious" - and would it have happened if not a good kick from Beijing?
And how many mistakes were made?

[hrych]

Firstly, the winners are not judged, there was a Supreme and there was his Minister and there was a Victory. Analysis is the General Staff’s business. No Soviet developments, all this was created in New Russia, but there was continuity of generations, but also Tsialkovsky and Mendeleev worked in the Russian Empire. In the same rocket science, the USSR succeeded in liquid rockets, including the brilliant Sineva, but there was a complete lag behind the enemy in solid fuel, hence the problems with operation, response speed and ... cost, as in production, operation and transportation, and by an order of magnitude. Yars, Mace and Iskander are our trump cards in the arms race and they are solid fuel.

[Andrey Yuryevich]

Quote: hrych

The armed forces that we have now are created under Mr. Serdyukov,

are you serious now ??? he only sold and reduced, without creating nichrome.

[hrych]

It was not he who cut it, but the Supreme. So it was necessary. Even before modern times, one way or another, the army was modeled on the Soviet one, albeit in a reduced and depressing state. Moreover, its vices, like hazing and theft in an exponential progression, Western Ukrainians dominate from the middle command staff to the generals. It got to the point that the officers and the ensign were selling weapons and ammunition to the enemies of the Ichkerians. The soldier was set up and sold into slavery. This abomination must and should be dispersed. Therefore, the Supreme Commander appointed a civil manager, without unnecessary attachments, etc. But he performed the tasks without question. I repeat, the result is obvious. Even the notorious Mistrals already look different when the ships of the "Syrian Express" - our large landing ships take four times less cargo, and taking into account the volumetric cargo, a couple of such things would be very useful. Even such military analysts as Tymoshenko and Baranets, as soon as they did not rally around the Mistrals, as well as on our website. So what? Unfortunately, the first to unravel the plans of our Supreme - intelligence officers and analysts of the enemy, which they did by blocking the transfer of products literally in front of the Syrian company. But if you turn on the analysis, then a picture emerges that it is possible that the beginning of the company is timed to coincide with the commissioning of these devices. It is impossible to consider everything unambiguously and categorically, years will pass and everything will look different. As they say that History and descendants will judge, even through the Trotskyite-Khrushchev propaganda "The wind of history will scatter ... well, as Stalin said, according to the memoirs of Kolantai.

[Scraptor]

On what? Cargoes are simply transported to ports by ordinary ships, Soviet lighters are still in the service of the US Navy, and it is good that this deal was thwarted by the French themselves - in such a "ship" the non-Papuans will immediately drown a battalion of paratroopers with aviation.

[Gorodovik]

Really said too loud. But you have gone to the other extreme. Like only we can into space. The US is slowly completing its ship, which has already been fired into orbit. The same Chinese do not stand still. And India is actively working in this direction.
Pro Supply. It is supplied not only with progress. There are Japanese and European supply ships. So yes, we are leaders, but this leadership is temporary unless we give out something new. But this is a problem. We need to play for the future and not for today.
And look for traitors less. For it can go into paranoia

[hrych]

I repeat, China is 50-60 years behind, i.e. takes the first steps, and the path is long, difficult and bloody. The Americans will tell you. About supply, yes there are many, but the main Progress. Dragon, Japanese HTV, all this in the wings. We give good statistics on the rotation of pilots: Union - 47 flights, at the moment there is no alternative. By truck, Progress is 62, the American Dragon and Sinus are 11, the Japanese HTV is 5. Everything else ceased to exist, including the Shuttle (37) and the European ATV (5). We see that the deceased Shuttle with 37 serving starts, something like that and then opposite 109 the launches of the manned and cargo Union are completely worthless. Without the Russian Federation, the ISS is not possible. Therefore, when there were thoughts about disconnecting the Russian module and its existence as a separate station, then practically everything else becomes space debris intended for descent from orbit.

From previous comments I understood that RD180 is yesterday, if there is today, then yesterday's "snow" is the best know-how - to earn, earn and earn again.

[kugelblitz]

Falcon has primitive gluttonous engines, with low pressure in the chambers, and even requires fuel for landing the stage. Which requires post-flight diagnosis and repair. About cheapness, this is advertising and nonsense.

[Gorodovik]

You forget that missiles are one of the most science-intensive and complex mechanisms. How do you think it is easier to create this colossus anew or just let it down check and refuel. Maybe for the money and a small savings but nonetheless. And this is an experience to which our cosmonautics can only dream

[kugelblitz]

SCHTA ?! First, ask about the volume of work after the return of the step, and then speak. The Americans have experience, but if you look into the rabbit hole, you will find out about the complex "tube" technology of engines, which does not allow increasing the pressure in the combustion chamber, and hence the specific impulse. Accordingly, the engine itself becomes heavier, more fuel and the size of the rocket are increasingly required.
Sometimes it’s funny for me to read naive comments, they say the Americans and Europeans created rockets so perfect that dense Russians can never catch them.
Fuel, for example, also costs a lot of money, and the GHG launched into orbit by the same Falcon, with the landing of the stage, is ridiculous for such a starting mass. No wonder they are planning a methane engine, primarily to reduce the cost of starting. Often it just comes out cheaper to assemble a disposable rocket than to make a heavy, voracious reusable rocket. The history of the Shuttle is hinting.

[kugelblitz]

The Americans tried to create an RS-68 combustion chamber using a similar technology, but Delta-4 exploded at the start ... the proud democratic birds did not catch it.

With equal thrust of rocket engines, their comparative thrust-weight ratio will not be decisive namely, specific impulse. .The higher its value, the less fuel the liquid propellant rocket uses to disperse a certain mass and, therefore, the higher the thrust ratio of the launch vehicle stage.

Thus, the thrust-to-weight ratio of the Falcon 9 1.1 LV is 1,2 (thrust of 600 tons / 503 tons of rocket mass), and the Zenith 2 with RD 171 1,5 (thrust of 720 tons / 470 tons of rocket weight) with a similar payload of 13 tons for the NOO.

And all thanks to the closed circuit and high pressure in the combustion chamber (263 at). Among the Americans, the RS-25 is the most effective. closed cycle. But due to the tube construction, the pressure in the combustion chamber does not exceed 192 atmospheres. The heir to the RS-68 was much worse and therefore merged.

what stupidity.
The design of the middle part of the LRE chamber:
1 and 2 - the inner and outer walls of the rocket engine chamber;
3 - axle; 4 - collector; 5 — branch pipe with a flange

The most widespread practice of firms in the USA, England and France is the method of manufacturing walls from profiled steel or aluminum tubes (see Fig. 30, c), although the method indicated in Fig. 30, b is also applied.

Shirt 2 is made of high strength materials - steel, titanium. It can be made continuous along the entire contour of the wall or in the form of individual rings, which is determined by the calculation of the strength of the rocket engine with the minimum weight of the structure. In some designs, the shirt is made by winding steel tape or dragging, followed by soldering. Shirts made of fiberglass impregnated with plastic are also used.

The trunnions 3 perceive the traction force of the chamber and are welded to the reinforced part of the jacket of the LRE chamber. In order to avoid large deformations of flexible pipelines when turning swinging chambers, fuel and oxidizer can be fed through axial drilling in the pins.

Something in your pictures do not observe the very friction welding? I see the gas burner heating, and the most fun welding and soldering are completely different things, especially with regard to different metals and alloys.
And friction welding is not such an ubertechnology, but simple and undemanding soldering with heating with high-frequency currents is an ingenious move, from the point of view of the technologist!
And as a mechanical engineer in your beautiful pictures, I saw two bottlenecks - the first excessive amount of machining, the second option with burners just killed on the spot - heating is uneven and stresses can occur, and therefore cracks!
During soldering, an inert gas may not be required in the presence of flux, or weak oxidation of metals.

[kugelblitz]

By the way, I remembered what the nozzles were, they used pin-type nozzles, the F-1 had a colander. The price of the engine is higher, but beats off at a lower mass and cost of a rocket with fuel.

On May 16, 2015, after the launch of Proton-M with the Mexican communications satellite Mexsat-1 at the estimated time, the spacecraft did not separate from the third stage of the launch vehicle. As a result, the satellite was lost. The cause of the disaster is the failure of the steering engine of the 3rd stage due to increased vibration loads caused by an increase in the imbalance of the rotor of the turbopump unit.

Proton-K (8K82K): September 27, 1967,22, November 1967,27, 1969, March 69, 8 (AMC Mars M-48), the main unit 8D49 of the engine 3DXNUMX of the XNUMXrd stage of the rocket spontaneously turned off. This happened due to the imbalance and duplexing of the bearings of the rotor of the turbopump unit, as a result of which the gap in the gas sealing element of the TNA turbine was completely selected, which led to the ignition of the turbopump unit

On October 27, 1999, the Express-A1 communications satellite was launched from the Baikonur cosmodrome using the Proton-K launch vehicle. At the 4th minute of the rocket's flight at an altitude of 105 km, the first main engine RD-0211 first failed, and then the entire propulsion system (it includes four RD 0211) of the second stage of the carrier.

For the lines:
During the satellite’s launch, the second start of the marching engines of the MD-3 booster block went abnormally, 29 seconds after launch, the 400-ton rocket exploded and collapsed due to a technical malfunction in its first stage, and the carrier rocket engine stopped at the 83rd second of the flight my job...

Regarding "primitiveness" I meant a dense open cycle, and if Musk is so straightforward with reusability, why did he not install the most perfect American RS-25?

The proton has 6 engines of the first stage, and the problems began to deliver recently due to the decline in the culture of production.

As a part of the Zenit-2 and Zenit-3SL LVs, three accidents of the RD-171 engine occurred:
4.10.1990 - the fifteenth launch of the Zenit-2 LV, which ended in an accident at the third second of the flight as a result of the explosion of the first stage engine. According to the conclusion of the emergency commission, the engine failure occurred due to the destruction of the swing unit of the gas path of the second chamber. The most likely cause of the fire was the ingress of the ignition initiator into the inner cavity of the swing unit in the form of a substance of organic origin with concentrated heat during the combustion of more than 30 kilojoules.
(how could he get there, except for the prosa TNA?)

20.05.1997/2/XNUMX - the twenty-eighth launch of the Zenit-XNUMX LV, which ended in an accident at the 49th second of the flight as a result of emergency shutdown of the engine of the first stage. The rocket fell 28 kilometers from the launch complex. The causes of the accident were not covered in detail, but on indirect grounds we can assume the ignition of the turbine.

31.01.2007/3/XNUMX - The launch of the Zenit-XNUMXSL LV from the Odyssey launch platform ended in an accident, the rocket exploded at the start. The Russian-Ukrainian interdepartmental commission for the investigation of the accident established that the cause of the accident was the ignition of a metal particle accidentally introduced from the outside in the oxidizer pump. This was the first flight of the upgraded RD-171M engine, ironically, one of the main goals of the modernization was to increase reliability.

[opus]

25.12.2009/171/1 during the fire acceptance test of the RD-XNUMXM engine at the stand of NPO Energomash OJSC, the engine failed with the destruction of the material part of the engine and individual systems of the stand. The commission, which included specialists from various departments of NPO Energomash, examined the results of processing telemetric measurements and the results of the analysis of the state of the material part, the results of the calculated estimates and the results of specially organized and conducted experimental studies concluded the following. XNUMX. Engine failure during its operation at the nominal traction mode occurred in the result of a fire for 17,6 seconds in the gas cavity behind the turbine turbine at the junction of the exhaust manifold of the turbine with the gas path of one of the chambers (chamber No. 2). The development of combustion led to destruction of 18,2 seconds gas path of the engine behind the turbine, explosion and fire. 2. The initiation of fire occurred as a result of ingress of a foreign object (substance) into the gas cavity in the process of manufacturing an engine that could not be detected by the routine inspection and control procedures. 3. The most probable is the organic nature of the foreign object (substance) that has entered the gas path during work with the subassembly of the “gas duct block” of the engine. 4. The identified cause of the RD-171M engine failure does not require the adoption of corrective measures for the RD-171M, RD-180 and RD-191 engines that have passed the fire acceptance tests. 5. The Commission developed and recommended a set of corrective measures to prevent the ingress of foreign objects (substances) into the internal cavities of all types of engines, and the introduction of an additional procedure for inspecting the gas path of engines at the final stages of assembly. However it is not very clear how, in the presence of organic pollution, ignition occurred only at the 18th second of engine operation.

Speculation

At the end of 1941, the first fire bench test of the A-4 rocket was carried out, in which an explosion occurred due to personnel error, the rocket and the stand were destroyed. In 1942, experimental launches began. The first successful launch of the fourth rocket took place on October 3, 1942. For the first time in the world, a rocket reached supersonic speed and touched the border of space, reaching an altitude of 90 km and flying 192 km. Obert himself, then in Peenemuende, congratulated von Braun and the developers. A large boulder was erected at the launch pad with the inscription: “On October 3, 1942, this stone fell from my heart. Werner von Braun. "

Mixture formation in the chamber was performed using prechambers on the hemispherical end of the chamber in the center and on concentric circles 19 prechambers were placed in which the fuel components were mixed by simple jet injection, which also negatively affected the specific thrust impulse. But it was practically impossible to find another technical solution for a camera of this size and shape.. With this design you can congratulate its author - Dr. Werner Thielwho died on 17.8.44 during a raid by British aviation, not Peenemuende.

- "Theirs" "shuttles" fly as before, and quite often ... and what about our beautiful "Buran"?

In 1990, work on the Energy-Buran program was suspended, and in 1993 the program was finally closed. The program was closed by a decision of the USSR Ministry of Aviation Industry at the agency level, but there was no official closure, only the President of the Russian Federation can cancel this program.

In October 1995, the Minister of Defense of Ukraine V.N. Shmarov announced that, as part of the implementation of the new military doctrine, the country's government had decided to reduce the military space forces and liquidate the Buran spacecraft receiving aerodrome, but said that by 2000 Ukraine will have a "compact orbital grouping of military space forces of 4-5 vehicles."

In 2002, the only Buran was destroyed during the collapse of the roof of the assembly and test building in Baikonur, in which it was stored with ready-made copies of the Energia launch vehicle.

“They were just replaced by Dragons. The essence of this has not changed.
“The first 'commercial' launch of the spacecraft to the ISS was made on October 7, 2012. The launch took place from the Cape Canaveral cosmodrome in Florida at 20:35 local time. The Dragon spacecraft docked with the ISS on October 10.

The truck delivered about 450 kilograms of payload to the ISS, including materials for 166 scientific experiments. Back to Earth, Dragon successfully returned about 900 kilograms of cargo, including decommissioned station details, as well as over 330 kilograms of research results.

The ship undocked from the ISS on October 28, 2012 at 17:29 Moscow time, and returned to Earth, splashed in the Pacific at 23:22 Moscow time, at a distance of about 300 km from the coast of California.

In the future, 11 more expeditions to the ISS are planned under the Commercial Resupply Services (CRS) contract, with an estimated value of $ 1,6 billion, concluded between SpaceX and NASA. "

On May 29, 2014, the company introduced a manned version of the Dragon reusable vehicle, which will allow the crew not only to get to the ISS, but to return to Earth with full control of the landing procedure. In the Dragon capsule, seven astronauts can simultaneously be located. Unlike the cargo version, it is able to dock with the ISS on its own, without using the station manipulator. The main differences are the controlled landing on engines (parachute scheme as a reserve), support for soft landing and a salon with chairs for astronauts and a control panel. It is also stated that the descent capsule will be reusable, the first unmanned flight is scheduled for 2015, manned - for 2016.

I do not know. what they bring there and where, but so far Russia is practically the only one serving the ISS, and the only country that makes manned launches. Let's see what they can do, but the example of the United States clearly shows that the space program is clearly dying out. They also buy rocket engines from Russia, probably not from a good life. As the saying goes, "we'll take a look," but I think it's all politics. They will make one launch, well, the second (provided that it works out), and then they will come back to Russia.

[Vadim237]

How Angara 5 can fly in 2019 with a manned ship if the final tests of this rocket are completed only in 2023.

[Sweles]

it's just a space auction, they want to bring down the price of launches on our alliances, can we do that? -Yes we can. The Union is a cheap and streamlined spaceship. For example, salaries at the Samara RCC Progress are such that there’s simply no where to reduce, people of the engineer and hard workers will not suffer, but if the main beneficiary of the start-ups of unions cut incomes, then there will be nothing wrong.

[Bad_gr]

For some reason, no one paid attention to the fact that they refused to launch Soyuz-ST, and this is a cosmodrome in French Guiana on the north-east coast of South America, which was specially built for our rocket, which means that in the near future the Union will favor another they are unlikely to refuse rockets.
Simply, at the moment, launching four satellites at once with one rocket is more economical than launching these four satellites with two missiles. There will be cargo for our missile - they will use it, and not some other one (which was probably calculated when choosing which missile to build a launch complex in Guiana)

[Orionvit]

You confuse a little economic feasibility with political conjuncture. It was necessary for politicians to impose sanctions against Russia, they did not look at multibillion-dollar losses and introduced them to their detriment. And it was precisely politicians and states who commanded outer space always and everywhere, and not economists and businessmen at all.

[Bayonet]

Quote: Bad_gr

and this is a cosmodrome in French Guiana on the northeast coast of South America, which was specially built for our rocket,

Not certainly in that way. The Kourou space center in French Guiana began to be built in 1965 at the initiative of the French Space Agency (CNES). The first launch from the Kourou cosmodrome was carried out on April 9, 1968. In 2007, work began on the launch site to build a site for launching Russian Soyuz-2 rockets.

[Bad_gr]

Quote: Bayonet

This is what was meant. Moreover, it is not a cheap option (with a hangar on top of a rocket standing on the launch pad).

Quote: avvg

And we will survive it too!

That's for sure, but you need to draw the right conclusions.
No one will allow a Russian corporation into its economic and technological niches, except by great necessity. And no WTO will help here.
First of all, we must rely on the domestic market. Accordingly, limit the use of currency, introduce the ruble for foreign trade.
You can buy abroad, as a rule, only parts, assemblies, some separate technical solutions, but not toilet paper and building materials for a billion dollars.
It still has a floating rate, of course, significantly reduces imports, but much more needs to be improved in currency regulation and, most importantly, to establish normal lending to industry. There are no examples in history. Take, for example, lending to industry in Germany at the end of the 30s of the last century.
One thing you need to know firmly in an economic system based on the US currency of Russia simply will not be allowed to develop effectively without washing, so skating.

[your1970]

"Take, for example, lending to industry in Germany at the end of the 30s of the last century."
Who lent? A number of the largest oligarchs, including American ones? Maggi, Nivea, Nestlé, Standard Oil, Ford, SCF, General Motors, General Electric, Kodak, Aybiem, Coca-Cola corporations (by the way, it was under Hitler that !!!) etc.
How did it end? Nuremberg ...
So do not give such examples of lending, like Germany in 30.

[iliitchitch]

They are pressing us, parasites, seriously. Isn't it time to "wooden" the ruble? It is stupid to arrange "buy a brick" for everyone, including the Chinese. They will not go anywhere, they will buy. Are we isolated? Come on, the duct tape won't be enough.

will not use Soyuz-ST’s Russian carrier to launch Galileo satellites - spacecraft in orbit will launch their own Ariane-5 heavy missiles

1. Only for the period 1995-2007, Arianspace placed orders for 99 pH at EADS, 43 launches were made, of which 39 were successful.
Do you need to go somewhere?
2. The cost of withdrawal
RN "Arian ECA" (Launch weight, kg 777000): 150 million euros, but it costs about 170 million euros per launch
can bring two satellites with a total mass of 10 kg and one satellite with a mass of 000 kg to the GPO.
Total of almost 21 tons
7142 Euro / kg
The Soyuz-ST launch vehicle (Launch weight 313 kg) can launch up to 000 kg (from Guiana, and maybe from the Republic of Belarus, then in fact 9000-3 kg), the launch cost is € 4000-60 million.
from 8000 Euro / kg
+ with delivery of trouble
+ The Soyuz-ST-B launch vehicle is going to TsSKB-Progress, and it needs to be delivered to Guiana:

+ Mobile service tower (manufactured with us, delivered there, assembled there, it must be maintained in good shape, again, it’s all ours)
In general, when ESA was NEEDED

they took advantage.

For practically GSO (GALILEO) indicators are even worse.
3.RB "Fregat" has been naughty lately
(The Soyuz-ST-B launch vehicle with the Fregat-MT upper stage and two European Galileo satellites, launched from the Kuru equatorial cosmodrome on August 22, 2014, did not put satellites into the calculated orbit due to abnormal operation of the Fregat-MT RB, presumably as a result of an error in the software on board and containing the incorrect flight mission)

Quote: СРЦ П-15

And when you need to launch one or two satellites, you still have to bow to Russia - you can't send the "ship" half empty.

1. The use of different options for payload containers allows the simultaneous launch of two to three satellites and placement of up to eight microsatellites. The launch vehicle is used to supply the International Space Station (ISS) with the help of cargo ships.

In TsSKB already feel the problems of production of rocket kerosene. Soyuz rockets, which are made in Samara, now fly on artificially created fuel, because initially only certain types of oil from specific wells were used to create kerosene for these missiles. This is mainly the oil of the Anastasievsk-Troitsky field in the Krasnodar Territory. But oil wells are depleted, and the currently used kerosene is a mixture of compositions that are extracted from several wells. According to experts, the deficit problem will only get worse here.

At TsSKB Progress, it was believed that the use of engines on LNG would “ensure a relatively low start-up cost - 1,5–2 times lower than on kerosene engines, high environmental friendliness, higher specific characteristics, a single engine and fuel type“ LNG + liquid oxygen ", which will greatly simplify the ground infrastructure."

[Orionvit]

I want to correct, the Europeans were quite technically developed. Now everything is moving by inertia, while specialists who were trained in the 80s are still alive. In Europe, a terrible shortage of qualified personnel. For example, in England in the field of military production or at nuclear power plants, foreigners cannot be legally employed. Scandal, no one to work. Almost all pensioners have their own, but there are no new personnel. Either stupid graduates of modern liberal education, or even stupid newcomers Negroes and Arabs.

[samoletil18]

It may blame, but based on the interests of Russia, I will be glad for the failure of European missile launches. Use GLONAS, you bastards! Why should Europeans navigate future owners from Africa and the Middle East?

[Olegater]

This is to be expected. Refusal from our carriers is good on the one hand. Let them fall to rockets and cause damage. I’m not sure that during the time when they used our media, Europe somehow developed and improved its media. On the other hand, we will not receive money from sales of carriers, and yet the financing of our space industry will slightly decrease. And another point - the increasing launches of Europeans of GPS satellites, this indicates preparation for a global conflict (I am not panicking, but trying to summarize what has been said) in the end, these navigation satellites will be used for military purposes. One more thing "The developers of the system claim that Galileo will be more accurate than its counterparts, and" will provide the Europeans independence from American GPS, Russian GLONASS and promising Chinese Compass "" but independence is doubtful, given how the politicians of the euro ...... we went under the louse. This is nothing more than an addition to the Amer ZhPS.

[donavi49]

Well, Arian-5 has excellent 83 launch statistics - 4 files, and all 4 files are the first 15 launches. After more than one emergency.

It was Arians who brought Rosetta out, it is Arians who are now using the ATV program (delivery of scientific blocks and important cargoes to the ISS).

Vega will be easy, but so far it’s been collected in pieces, two a year.

Well, if Elon copes, there will be a revolution in space affairs. The Falcon is assembled as a Ford, and then they are again launched into space, which further reduces the cost. The last mission in December 2015 for the first time completely completed the program, brought out all the satellites, and the stage sat down softly.

[sir_obs]

There is no revolution here. The return steps were worked out by both the Americans and us. With the same fit and even pro-nary hollows. But such a scheme was abandoned. Repeated preparation for the launch of such a stage is not much cheaper than manufacturing a new one. And he eats more fuel, for landing you need to decently store up.
Only hassle with cleaning from soot and soot. And if you look at the stage it is all black, and especially in the area of ​​engines. And everything should be mirror polished so as not to create additional temperature loads. In addition, it is not known how the structure itself withstood the landing, the modet deformed it and how much the engines will work reliably during repeated starts.
There are so far more questions than answers to them.
And in addition, all starts at the American go to the stoton of the sea. So, they will have to land in the wild, that is, on the platform. And they still haven’t succeeded.
It is too early to make all bets on this project.

[Scraptor]

All that remains is the question of why all this if the step can simply be parachuted

[Red_Hamer]

Come on, the whole earth's orbit is one big garbage dump. there is little trash there, so we will dirt the near-earth space ahead of schedule, just do not yell, that Russian satellites fly nearby, and they behave strangely.

This is reasonable from the European point of view. Competition in the space launch market. "Arian 5"- the rocket is expensive, and then there is"Falcon-9"came to the market. They need to load their rocket.

I'm interested in examine the whole scheme for theft. Specifically, explore the launch contract. The service tower, as far as I know, was made in Russia; for whose money? If it turns out that they are for ours and if it turns out that on the European side, the contract easily makes it possible to abandon the use of the Soyuz-STA missile (that is, infrastructure will not pay off), then it will be either sloppiness or theft. Who traveled to Europe and signed defective contracts? To the nail!

I don’t know who was driving there, but there was infa that they bought 15-20 launches in the near future. In addition, they launch not only Galileo, but also third-party satellites, since it’s easier to launch from Guiana, it’s more weight and higher orbit

[Vitaly Anisimov]

Well, yourself, so yourself ... We will survive! Good luck from the heart ...

[Deniska]

Why worry then? You just need to strive to create a cheaper, lifting and competitive rocket.

[vfqjh]

Flag in their hands! The staff also boasted that without our engines they could cope with space, and the contract was extended. In how !!!

[MolGro]

Well, compare 2 rockets of different classes) stupid!
Ariane-5 (NOO-21t, GPO-6,5t) is comparable only with Proton-M (NOO-23t, GPO-6,74t, GSO-3.7t) or Angara-A5 (NOO-38t, GPO-12t GSO-10t) and then not in favor of Europeans)

[Gormenghast]

"Angara-5" only with KBTK will have such characteristics. And when this oxygen-hydrogen upper stage will appear is unknown. Terms are called only when they are met. Hydrogen technology in Russia has been lost since the dismemberment of the USSR.

Ariane-5 is our competitor only because of the more favorable location of the cosmodrome (closer to the equator). The rocket itself is not the top of perfection: some powder boosters are worth something.
By the way, if we recall the ozone layer, the products of the combustion of solid fuel accelerators with ozone are not very friendly: after their interaction, huge holes remain in the ozone layer.

[Cfif2303]

God forbid that European missiles do not fall ... a lot of garbage ...

[Pencil]

I think the matter is different. I already wrote once that, in principle, insurance covers damage. But purely material. But the damage from the loss of satellites, which were created over the years, which laid a huge intellectual base, designed to provide a technical advantage for the next 10 years, this will not be covered by any, even 10-fold insurance. When, for example, they drown a unique satellite tracking missile launches, which have been done for 10 years. Who will give the country another 10 years and billions of rubles to repeat? Razzzz - and the country is thrown back 10 years. Only the governing green managers - believe that money is everything ...

The ten-year development is billions, but also the complete works of technical documentation for cloning during the year

Vova is the right kid, he will not let the astronautics bend!

Quote: Haettenschweiler

- Roscosmos may not survive. He survived on orders from outside. There will be no orders - there will be no our astronautics.

To date, there are more than 2 Soyuz-50 launches from Plesetsk and Bayk, and Soyuz-ST was launched 2 times from Guiana, why can you "not survive" here?
Of course we have a lot of problems, but not everything is so gloomy

[Leprekon]

Yes, and to hell with them. But only in case of failure with their rocket, establish a new, increased tariff for using ours!

[Support]

PUTIN, damn it, shoot down all the ministers led by the prime minister, disperse the main bandits-the deputies and there will be grace in Russia .... they’re embarrassed, they’ve already been so stupid ...

It will survive if officials do not steal.

- So I say - the end of our space program, if there are no orders.

You say that the space program and Roscosmos is a commercial enterprise. In all countries, space programs have always been funded by the state, and commercial launches, this is so, to maintain the pants, to slightly reduce the financial burden, well, to show yourself. It’s like advertising and political agitation, and of course wipe the nose of competitors.

[Ajent cho]

Those. do they have their own "import substitution"?

[Gerhard]

I want comments from the dowel who was broadcasting about the trampolines that the "trampoline" was a rocket?

Maybe they can. All the same, the French collected the sixth Ariana for 6 years, but settled on the fifth. It remains only to run

[Stranger]

Hi, they scored the main thing, they just wash money. By the way, this is not the first time, I live 14 years in Ger. on all channels, I’ll understand and deny which Great Cosmonauts a-ts and some information about the USSR and R.

[gergi]

God grant the calves of the wolf catch. See do not be divorced, Europeans!

[electrooleg]

I wonder what their percentage of failure and unsuccessful launches will be compared to our missiles.

[evge-malyshev]

Well ... refused and refused. We survive. Moreover, their own carrier arrived in time.

Quote: SRC P-15

And when you need to launch one or two satellites, you still have to bow to Russia - you can't send the "ship" half empty.

Something recently in VO more and more similar blunders began to appear. The title is one - the text is different. In the heading, France REFUSED to launch its navigation satellites by our Unions-ST, in the text that in 2016 it would not launch by the Unions.
In 2016, 4 satellites will be launched with one rocket. In 2017, our Union will launch the next TWO satellites

Quote: hrych

Yars, Mace and Iskander are our trump cards in the arms race and they are solid fuel.

Of the three mentioned, two are Soviet-made

Quote: Orionvit

I do not know. what they bring there and where, but so far, that Russia is practically the only one serving the ISS

So what? How long will this last? Manned really YET only we. The trucks are already being pushed aside. European and Japanese take several times more cargo than "Progress", plus "Dragon" and "Swan"

Quote: Orionvit

Russia is the only country that produces manned launches.

You have to understand that a country like China is in a different, alternative reality ????

Quote: Orionvit

Let's see what they do, but with the example of the United States, it is clear that the space program is clearly dying out.

Who? We have? It seems ... Others, on the contrary, are developing their space programs.

Quote: Orionvit

Won and rocket engines are bought from Russia, probably not from a good life.

How much is this, how can a mantra be repeated? We bought a hundred, but as much conversation as if we had bought tens of thousands of engines. And while they are buying, we have at least a factory afloat. A stop? What then? But they will stop it in the next two to three years. Engines with similar characteristics are now undergoing fire tests.

Quote: Orionvit

As the saying goes, "we'll take a look," but I think it's all politics. They will make one launch, well, the second (provided that it works out), and then they will come back to Russia.

It will be late to watch. The Americans are developing 5 or 6 new ships, including only one pure cargo. Dates of test flights - 2016-2017. But we moved our new ship to 2024. And what will be more preferable for the customer. Send, even for a large amount, 4-5 cosmonauts to orbit at a time, or pay Russians, albeit cheaper for a single launch, but at least 3 launches ???

[project sity]

I don’t know why hope in Europe! They have already heated Russia with the Ministry of Industry, and here it is.
