NASA signs contract to buy RS-25 engines

NASA has signed an agreement with Aerojet Rocketdyn to resume the production of RS-25 rocket engines for the Space Launch System (SLS), transmits Lenta.ru report message of the press service of the company.

The contract value is about $ 1,16 billion, according to the time it is calculated until the end of September 2024. Under the agreement, it is planned to restart production of the RS-25 engine.

“Aerojet Rocketdyne is the main contractor for RS-25. - The first stage of the SLS rocket will be equipped with four engines of this model, - the report says. “Three liquid rocket engines for oxygen and hydrogen RS-25 were previously used in the Space Shuttle.”

“Space Launch System is designed as the most powerful rocket in the world. Its perspective mission is to provide the start of a manned Martian expedition. The first test flight of the SLS is scheduled for 2018 year. Rocket carrying capacity is planned at the level of 70 tons, it will carry the Orion spacecraft in unmanned mode. In the future, this figure will be increased to a record 130 tons, "- the agency writes.

SLS is being developed as part of a contract between NASA and Boeing. With the help of this carrier, it is planned to launch the reusable Orion spacecraft, which in 2030 will deliver American astronauts to Mars.

Ours will not beat anything! I personally do not like it! Would behave in an adult way, in their language: Nothing personal (especially with enemies), only - business! And then they look at us like Kat at Danila (moreover, Danila is the personification of our man, and Kat is a similar trash for "them") from the movie "Brother":
- Why are you pushing such bullshit? The player is such a real one, but dressed like a sucker!

on the other hand, in their bullshit films, the Martians were pretty much messed up by the Americans themselves with flights to Mars ... in real life, these upstarts still use our rockets ...

the reusable Orion ship, which in 2030 is supposed to deliver American astronauts to Mars.

At the moment, sending astronauts to Mars is impossible. I doubt that by 2030. This requires completely new technology. Even to send one carriage of stewed meat to one end of the two, a train of water, at least (even if there is ice, at least a mini-factory is needed to extract oxygen and hydrogen from it (to provide these two and water the garden, power supply, moreover, breathing pure oxygen, too, is not ais, (almost 80% of the earth’s air is nitrogen!) (and the gastarbeiters who build it, who also need to eat, drink, breathe, are a joke, of course)! In addition to everything else! It's in aerial movies ( eg Martian - Svezhak 2015) show about the garden and other crap, for stupid-dreamers-dreamers and their kids! And to return back! The gravity is not much less than on Earth! the launch table, the fuel just won't appear there either!
So think (and not fantasize) yourself about the possibility of this! Based on who studied what!
And the preparation (training) for the flight both with us and with them is the study, study of the human factor in conditions of loneliness, weightlessness, psychological void, physical exertion, etc. etc.!

you need several carriages of stew, a train of water,

At space stations, including the ISS, a closed cycle of water supply is used. So water is not a problem - a train is not needed.

And ours here from which side ??? The American company Aerojet Rocketdyne is the main contractor for RS-25.

the engine wasn’t used on shuttles, the accelerators are the same, in fact it’s a space shuttle, but without a shuttle, why did you need to wait 20-30 years to think of such a rocket? In about 30 years you’ll look and they’ll fix somewhere F1 ...

Almost two times worse than the RD-180 they bought.

This is the Voing company and not the Russian Federation. They don't have a new engine, it's an old development.

Passed by. We know. Then again, rush to us for the engines. They don’t know how to do anything themselves.

In the future, 130 tons. According to the project, Energia-Vulkan could have brought out 200 tons. Somewhere I saw that it would take 5 years to revive production. And of course money and desire.

[Vadim237]

You can forget about this project forever - we again blew the Americans by means of launching into space.

[Irokez]

Well, it's slippery and two-faced. Sanctions are so sanctions. And then we also need to shut off our fuel for the rockets and let the engines develop (if they can), and these are our future orders for the launch of all trash from our carriers into space.

The energy is 100 tons, and the Volcano is a project that has not been implemented, and at LEO. But you took it off your tongue, really what kind of buoy you dumped into the "Angara" if there is such a powerful rocket, and I think it is possible and NECESSARY to revive the project. And most likely they will revive, I'm sure.

It would be better if they continued to buy our engines, think about it, because this is production and jobs. Instead of finely annoying the enemy with sanctions, it’s better to spite the Americans to develop their industry in Russia at the expense of their money.

Cool 130 tons. In 2018, the first flight. This is not a shed

[Lumumba]

For F-1 engines, production technology has been lost, and irrevocably. This was due to the closure of the Apollo program and the throwing out of thousands of key engineers and personnel "into the cold." The know-how and experience were not passed on to the next generation of engineers and Von Braun's unique technology was lost.

But on RS-25, everything has not yet been lost. So in the end they raise what is.

The F-1 for this project has excess capacity. It is possible to stick a ZiLovsky engine on a Zhiguli, but what the hell is it needed?

[Vadim237]

Incidentally, this advanced RS 25 was supplied with a compressor from F 1.

[Scraptor]

Why not just F-1? Compressor is what?

[JonnyT]

well, they’re holding the flag. Just as it does not fit, what will they launch them? Could it be expensive?

The Americans, after imposing sanctions, began to draft a new engine to replace our
RD-180, allocated funds. But apparently, it is not so simple, or the timing, or technology?
So we decided to take out the old stuff from the chest - in your opinion, "a goat's face".

[beer-youk]

The whole trouble, in my opinion, is that fresh foreign (Jewish, Russian, Chinese, Pakistani and further on the list) brains do not go to Chtat, and those that arrived are yesterday, but they never had their own. You will revive the dinosaur here!

Operating time RS-25 - from April 12, 1981. Successfully used at the Space Shuttle MTKK. Fuel is liquid hydrogen. Thrust 222,6 tf in vacuum, 181,4 tf at sea level.
The RD-180 was created in the mid-90s on the basis of the RD-170 engine (created in 1981). Fuel - kerosene. Thrust: Vacuum: 423.4 tf. Sea level: 390.2 tf.
The age difference, frankly, is not too big. Here is a "junk from the chest"

Maybe because the Angara is a modular system, four missiles from light to heavy?
Virtually all media?
Or because the restoration of production technology engine only RD-0120 needed about a billion evergreen raccoons at zero year prices.
And the restoration of production total complex - generally astronomical amounts.
But what for? Here specifically?
Bring your dacha into space?
What specific tasks require immediate investment from two (inflation sir) to thirty forty billion dollars in the restoration of energy production?
Money nowhere to spend? Do we have all new aircraft-tanks-missile systems-submarines new?
All fighters in Warriors? Are all pensioners fed, all orphanages in the European standard repaired? Tomographs in every village hospital?
What would threaten a thuja cloud of money in a carrier on which there is nothing to run?
