Can you get me this close next time? I'll bring some Nomex, a lawn chair, and some beer. We'll make an afternoon of it.
EDIT: Oh, and earplugs. Forgot the earplugs.

We're about to burn through a shitload of liquid hydrogen over here.

It's cool on the cryo engine with the temperature difference being 5,000F just a handful of feet apart.
If you were that close, you would get sucked into the exhaust thrust, never to be seen or heard from again.

If you are burning 15000 gallons/min, how many minutes does a test run? Is it just 1 or multiple a day?
Posted on 3/23/17 at 4:42 pm to TigerTatorTots
Yeah. It doesn't sip. It guzzles. Just over a ton and a half of LH2 and LOX a second for eight and a half minutes total, for the shuttle's engines.
The pressures the fuel turbopump develops are staggering, too. If you shot the hydrogen into the air instead of into the chamber, it would go somewhere around 35-40 miles straight up (assuming the hydrogen didn't boil off).
It's a beast, but the F1 still thinks it's cute.

They run about one per month for the RS-25.
Aerojet-Rocketdyne operates on a smaller set of test stands and tests more frequently.

...so I'm gonna need some rope, too, huh?

How can a regular jackleg like me go see dem dere rocket motors?

The Infinity Space Center at the Exit 2 rest stop runs a tour bus out here when the test is open to the public.
Don't know how frequent the tests are open to the public, though.

Added a short video from the start of the test in the OP.

How close are you to the test stand?
Posted on 3/23/17 at 5:06 pm to Skank_hunt42
No.
However, it is cool that the test stands have underground passageways that link them to the test control center for each cluster of stands.
I was down there the other day and it reminded me of video game. Dark as shite, very narrow (and wide.. haha) pipes running down both sides and puddles of water all throughout the tunnel. I was half expecting a zombie or ghoul to jump out and attack me.

I remember we used to be able to hear the tests all the way in Covington. We go on the porch when they were supposed go happen.
I ran outside today at work and couldnt hear anything. Was sad.

Official burn time was ~1300-1308..

Got to attend a couple of tests after work,at MSFC.Just sittin on a blanket on the hill,sippin some beer.
Both times,the tests were actually scheduled for daylight hours,but somehow got delayed just long enough to happen after dark.LUCKY ME!
It's an awesome experience,to watch and feel.

Can you hire me? I'm good at fixing lawnmowers and I am currently developing a propulsion system that uses only Mentos and a top secret soda product for thrust.
