Disclaimer: window for the boom is the within the next 4 hours. With no real data on the fueling / prep for the SH booster they guys don't have an accurate time on when it will happen. Once the frost ring happens though its generally within 15 minutes.

It's there anyway to enact an extremely high tax for private citizens to re-enter Earth's atmosphere by tomorrow morning?

"Starbase Texas"  ??  Is that name still open for review?

Lots of venting! probably not too much longer.

Are they venting pressure or purging lines?

they are currently fueling so its venting the pressure. when the tanks purge its a very dramatic vent at the top.

CSB to fill the time.
I was 4 years old and watched the Apollo 11 launch and moon landing from the inside of a cardboard dishwasher box my dad decorated with drawings of dials and buttons.  He used popsicle sticks to make levers.  And I had my spacesuit outfit on with my name stitched on the chest because I was a real astronaut.

yes. any longer and they set the ground on fire and shoot molten concrete back up into the engines.

Well that was...something.

Sure as heck was LOUD if short. Like the stream hosts stated it took a few seconds for the sound to reach the camera emplacement. They're going to have over twenty of those engines and that was just three ( maybe ). The full-fledged bastard will be thunderous indeed.

/ I can't wait to see it.

Yes. Unless there is a late boom.

A static fire is a firing of rocket engines while rocket is held down. It is usually rather short.

My parents had a Moon party. We were allowed to watch though, and stayed up real late while the drinks flowed.

Sure as heck burned the ones for the shuttle at Aerojet for a long time. Solid boosters have no shut-off, they're enormous bottle rockets. Shook the whole city for it seemed at least a minute. So farking cool.

/ The 1970s and 1980s were a BOOMing time in these here parts.

Only gonna be about 9 dB louder. +3 dB for every doubling of the source, so if 3 engines is this loud, then 6 engines is +3 dB, 12 engines is +6 dB, and 24 engines is +9 dB.

Wow...  wish I had money for that.

/Did, however, get a couple of NSF shirts and a beach towel after the SN15 test.

It seemed a little anticlimactic, but unless you are willing to destroy everything on the pad, you don't have to do a run to failure to find out that things are working as expected.

I believe the design is up to 32 engines now.  Apparently, SpaceX decided to eliminate vectoring most of the engines and add a few more.
 
2021-07-19 10:01:15 PM  
Yep, that's what happens the first time.

Ahhhhhh.....okay

They used to test the F-1's for the first stage in Mississippi, then barge them on over to Michould for installation.

I saw several of the Shuttle RS-25's tested at Stennis.  The cool thing about a full burn test (8 1/2 minutes) is that it put so much water vapor in the air from the rocket exhaust and the water dumped into the flame trough that it would rain about ten minutes after the test.
