Milestone Hot Fire Engine Test for NASA's Space Launch System Rocket

NASA is a step closer to returning astronauts to the Moon in the next five years following this successful “hot fire” test of flight engine No. 2062 on the A-1 Test Stand at Stennis Space Center in Mississippi. This April 4, 2019 test caps more than four years of testing for the RS-25 engines that will help power the first four missions of the Space Launch System rockets. It also concludes a 51-month test series that demonstrated RS-25 engines can perform at the higher power level needed to launch the super heavy-lift SLS rocket.

Haha, I love NASA doing public relations stuff, I might have to admit it's working

[coreytaylor]

now imagine 4 of these and two solid rocket boosters going off at once

Then the engineers wait impatiently as the engine and building cool down so they can begin disassembling the engine, nitpick over every component's condition, measure the burn through in the bell chamber wall/fuel lines and put it all back together for its next run.

Sounds like my kind of job!
Great work!

Just curious about the thumbs down, what were you hoping for from a test firing of a rocket engine that you didn't get?

[mocko]

I mean guys... can you imagine in how a great era are we living to have all this at a click?

Editor : i want the biggest fog machine in the market

Nasa : this

A moonbase is closer to become a reality ♡

[Fedaykin]

I pray in my lifetime to see humans walking on the Moon again and humans making a real presence in outer space...

I believe that NASA is ready for the challenge of moving forward to the Moon! 🚀

This video _and_ the Falcon Heavy static fire video... *at the same time!* I've got goosebumps. 🚀🚀

[KrustyKlown]

Full 8 minute burn, impressive .... ready to go .. .build some more, bolt them on, lets GO!!!

[bahman]

feel the power, wow, 4 or 5 of this together rock .

[yehat]

I think it works. That is an impressive engine.

How many times are they going to test the RS25? This has to be the 100th hot fire. Get it done already.

I thought NASA was out of the Transport business and that was now SpaceX job... it's a great time to be alive.

No wonder yesterday and today is foggy and humid 😂

V8s, Bald Eagles, and beautiful RS-25s... Murica Baby

[imanoobwhoplayspubg]

Woah let me try this with our speaker on midnight hehehe

[jamescorvett]

great test! though it might have raised humidity in Mississippi by 50%. lol

What a beautiful piece of equipment. It is such a shame they are not able to recover and reuse.
