SLS Green Run - NASA Ignites RS-25s (Slow-Mo)

The Core Stage of NASA's next moon rocket, SLS, static fires its four RS-25 main engines for 67.2 seconds during the Green Run test. Engine #4 had a "Major Component Failure", or MCF, signaling SLS to shutdown early. NASA is working to find the issue seen during the test.

Rs25: ignited
Trees: be moisturized
Deer: wtf

[quarkquinn]

Even the deer were intrigued ☆ Thank you for this!

0:19 "each of the four engines have flown Space Shuttle missions previously"
these pieces of art should be in a museum, not the bottom of the ocean.

3:19 look at the deers left corner! They're like the hell are these humans doing now?

[sebringb]

It's a consensus; the most interesting thing in that video at 2:35 was the reaction from the herd of deer... 😜

[MrDuncanDonut]

I love the sound of rocket engines, so deep and guttural. Sends shivers down mine spine, even the Deer were amazed by this awesome spectacle.

[MrStoney]

Ok so this is for NASA's next moon rocket... Powered by engines previously flown on the Space Shuttle...? I realise that relying on one company is probably bad business sense, but this seems like an awful lot of money for what seems to be old technology repurposed.

[ReadTheShrill]

I wish the NASA feed had captured the sound like that. Nice job.

[Isbjoern]

Same whup sound on engine shutdown as I've heard on raptor static fire shutdowns

Men of the past: where will I get my next meal?
Men of today: We make our own clouds
Men of the future: We have cloud cities

Video including slomo was shorter than the full burn expected 😂

I love how they tried to do a SpaceX and say it was successful. SLS aborting at this point is catastrophic for project that is already a catastrophe.

[SuperbonyTheCat]

😺 2:50 the deer in the lower left of the picture are also interested 😺

[brandonfleming]

Deers: Holy shit that's where clouds come from, Todd!!!

[cornerofthemoon]

Yes it's difficult for old hardware to perform for more than a minute.

[drewley]

That audio is beautiful! I’m such a space nerd lol!

[MarkLambertMusic]

Say what you will about the SLS program, but there is no doubt this is a visual treat.

[Bing]

Awesome video again, guys!

And your music during the end credits is fascinatingly addictive! Have you thought about releasing a full track of it, or is it possible to get the stems from somewhere so I can extend it myself? Hope you see this :)

👍👏👏👏 Это было красиво! ☁️🌪🌧🌈 Ничего, всё наладится. Они ещё полетят. ☺

Note the deer in the lower left corner. It amazing they didnt run away
