Stennis Space Center has long been known as the agency’s largest rocket testing facility and they have been extremely busy with the testing of the upgraded RS-25 engines. In fact all RS-25 Engine testing happens exclusively at Stennis Space Center! If these look familiar to you, it may be due to the fact that they were used as the space shuttle main engine for the last 30 years. Compared to the 3 RS-25 engines that the space shuttle had the SLS will utilize 4 of them to produce 2 Million pounds of thrust. The thorough testing of the RS-25 plays an essential role in upholding NASA’s high standards of efficient and reliable engines.

[@Backyardmech1]

Pretty cool to see NASA has enough smarts to reverse engineer engines that engineers 50+ years ago secured their jobs with making personal notes. Now they’ve been retired for ~30 years or more, also mostly gone. Also the old engineers designed these engines with slide rules and ingenuity. Not computer models and other computer aided guesstimations.

Great effort guys, the new SLS is 🔥🔥. I just want to share my thought, I am not degrading the efforts, sometime it feels like why we are stuck at this technology? Can't we use atomic energy to lift off? With that we can cut down the large fuel compartments of the ship.. Another guy in the comment section has talked about anti-gravity propulsion just as my thought, is this too filmy? Sci-fi movie effect?🤓

Atomic energy cant produce such large amount of gases, it can only produce heat energy, for rocket very large amount of burning gases are required

[@joewoodchuck3824]

What is the shower of something (sparks?) before the rocket is lit? Is that how it ignites? I would have thought ignition to be internal. Why do the nozzles move around horizontally after ignition occurs?

[@thecheekibreeki3197]

Sparks ignite the engine and the engines move cause the thrust pushs the the core

[@KindGottes92]

The sparks are there to burn unburned fuel to prevent building of an explosive environment. The ignition of the engine is internal. As mentioned bevore, the movement is the steering mechanism of the engines.

[@aleksandersuur9475]

The heart of a rocket is it's first stage engine, everything else follows from that. So, what are the outstanding characteristics of RS-25? Excellent ISP as with all hydrogen engines. That would be great in an upper stage, for a first stage it's of limited usefulness. High level of complexity and cost, again characteristic of hydrogen engines. In case of RS-25 the unit cost really stands out at 60mil per engine, or about the advertised launch cost of entire Falcon 9. And SLS needs four of them. Piss poor TWR, again characteristic for hydrogen engine, acceptable for upper stage, but necessitates solid boosters in first stage completely nullifying ISP advantage. Which would be ok, if NASA could get SRB-s cheaply, they can't. So basically overpriced and unsuitable for the selected job, and the rocket they will power will be the same as a result. So why did NASA select them? Because that's what they had, they didn't have a more suitable engine. Instead they should have started by acknowledging they don't have suitable components to make the rocket they want. Engine development is expensive, but it's not as expensive as SLS development has proven to be.

[@dsyncwashere8077]

Agreed

[@paulround8501]

I think they could pay for something like 8 falcon heavy launches with one launch of this thing.

[@myfavoritemartian1]

The SLS is way over budget and ten years behind schedule. The first SLS booster they pressure tested blew up bigtime. The first completed SLS booster has been on the Mississippi test stand since January 22, 2020.. Can anyone tell me if it has even lit off once? They only say, "Later this year." (And they didn't even have to build the test stands as they were built to test the Saturn V and were declared national monuments. Now NASA decides to use them. What would have happened if we had let them tear them down like they did the Mercury and Gemini launch towers? #Still using 1960's infrastructure, Go NASA)

[@cindywinters3221]

NASA is great at making these animations, however that is as close to building the SLS as NASA will get.

[@joevignolor4u949]

[@cindywinters3221]

@jrizzelable Dont hold your breath.

[@cindywinters3221]

@jrizzelable You seem to be well informed. Can you explain why SLS is taking so long? SLS is using Shuttle main engines, Shuttle SRB,s and a new and improved Apollo space capsule. The Orion spacecraft made its 1 and only test flight in December of 2014 on a Delta 4 Heavy rocket. With all that "off the shelf technology" you wold have thought it would be flying now. The Saturn 5 rocket was built in less than 10 years and all its technology was scratch built?

[@cindywinters3221]

Just waiting on a reply or are you going to call me a " Dip Shit".

[@VV-ln7fq]

How do they measure the thrust of the engines? Do they push against a giant spring with a gauge on it?

[@corneraction6765]

My best guess: They weigh the engine and then it on a full tank of gas. Then they put the engine with a full tank of gas on a rail and measure the speed. Measuring with a spring could also work.

We tested our rocket stages on the ground while the Russians just launched their's untested. Ground testing made failure analysis much easier and more effective. Now close to 50 years after Apollo that investment is still paying off.

[@joevignolor4u949]

@@azeezbawumia6511 If they had a test stand like the Americans they could have mounted an entire N-1 first stage onto it and test fired all the engines at once. At least one N-1 blew up during flight because of a single engine failure in the first stage. That would have happened on the ground if they had a test stand. Plus, the test stands were what allowed the Americans to work the bugs out of the giant F-1 engines on the Saturn V. If the Russians had similar facilities they might have been able to develop an engine comparable to the F-1 and been able to reduce the number of engines on the N-1 from 30 to just 5.

[@joevignolor4u949]

@@azeezbawumia6511 Maybe so. But the American design philosophy of at least testing the individual engines and stages on a test stand rather than just assembling the whole rocket and launching it definitely paid off. Even figuring out how to reliably start an engine as big as the F-1 took many test runs on the stand just to come up with the proper starting sequence.
