Full Duration Engine Test for Space Launch System Rocket
About | Information | History | Online | Facts | Discovery
NASA tested one of their RS-25 engines today in a full duration test at the Stennis Space Center in Mississippi. Four RS-25 engines will be mounted to the first stage of the Space Launch System (SLS) rocket that NASA will use to send astronauts further than ever before to locations such as Mars. The engine uses liquid oxygen and liquid hydrogen and burned for 535 seconds, ignition occurred at 21:00 UTC.

Flat earthers be like"OMG what a waste, the earth is flat and it is fake anyway"
Everyone else:
1. This is real
2. Earth is round
3. They literally took water, split it into hydrogen and oxygen, and put them back together. -
It's strange how the exhaust nozzle can be so cold that it could inflict serious bodily injury if someone were to touch it yet just a few feet away it's so hot that it would incinerate someone almost instantaneously if they got too close.

PETABYTES of information were collected during this test. Great googley moogley!
-
That's what I would call, brute power.
-
Wow. "Beautiful" is the only word I can use to describe the science and engineering behind every single thing you see in this video.
-
awesome
-
What generates the steam? The water or the blast hitting the ground?

Kudos to the engineers and personnel involved in this project, but on a greater scheme I wish NASA had instead continued refining the shuttle concept (not merely the current vehicle) and given us a a truely efficient means of assembling true interplanetary spacecraft in Earth orbit that are themselves reusable trucks between planetary orbits instead of literally one-shot systems. My relative was with a X-20 subcontractor here long ago and all with that advanced canceled spaceplane knew that action was a grand mistake that set us back exploiting LEO 20 years.

I could use that Turbo sitting on that engine.

And there'll be rain somewhere near
-
i wonder what would happen to you if you were in the same room as that engine when it went off.
-
the fact that that is just one motor is unbelieveable

So this single engine burns about 150.000 US gal of liquid hydrogen and 60.000 US gal of liquid oxygen during its 535 second run? For the full scale test they will use about 840.000 gal of liquid propellants for four engines. In metrics it's about 3.180.000 liters of fuel in just 535 seconds. That's 5.94 cubic meters each second. HOW IS THIS EVEN POSSIBLE?!!!!

What a waste of talent. The SLS is going nowhere.

This test appears to be using the same test stand that was used to test fire the Saturn V first stage engines. It has been extensively modified of course but the base of the stand looks similar to the one shown in pictures from back in the 1960's.

Is it just me, or is the nozzle glowing? The temperature in the main combustion chamber has to be at least 6,000 degrees F, and even though liquid hydrogen circulates through the chamber walls, the metal must get very hot when the engine is operating.

We get it! You vape!

Goood! Let's put some Pig in there and TADAH instant Roast Pig. We can have festive after that.

It would be a lot louder if not for the zillions of gallons of water being pumped into the exhaust chamber below the rocket nozzle during the burn...
