Add Moar Boosters!

[Torquemadus]

It's time to add moar boosters!

Main coverage starts at 12:24

[Scotius]

So. Much. POWER! Awesome sight. And sound.

[SpaceExplorer]

Wow! Just imagine the amount of heat and power that the booster puts off! Something like this would be awesome to experience in person!

At about 44:05, you can see the rocks smoking.

[mythbusters844]

From the insane sound and light from that, you'd expect it to melt the sand behind it. Oh well, guess APCP fuel can't melt sand dunes.

Actually, I think that's just dust that's being kicked up by the acoustic energy. Rocket launches are so loud they have to have sound suppression systems to keep the sound from reflecting off the pad and damaging the rocket. If the sound of the motor wasn't loud enough by itself to kick up dust, I'd be shocked.

Youtubes captioning is perfect for once. I wish it would be perfect ALL the time

Edit: 99% perfect anyway.

There was a fly landing on the hill behind the nozzle at T -1 sec when a moment later a swift lizard snatched him between his jaw. In that brief moment

he was thinking 'is this going to be my end?' Questions that should never be asked. That was the source of the smoke coming from the rocks.

[smjjames]

What was that square thing on a pole behind the rocket?

[Voidryder]

Oh Baby, get the wieners. We're going to a barbecue! That was impressive, but of course the engineer in me is going, so just how big are those restraining bolts....

I can't tell for sure, but they sometimes use things like stainless steel mirrors to film explosions on test ranges.

This allows the camera to be placed in a safer spot that is more likely to survive.

If it is a mirror, it looks like it is set up to view the interior of the solid motor when it first fires.

That is A LOT of radiating heat coming of burning fuel particles. I wouldn't be surprised if the smoke coming of the hill next to the booster was actually water vapor being pushed out of the ground by the heat, in addition to dust being picked up by the air current.

The surface plants and animals would have been toasted immediately, but there are plant roots and stuff under the surface that would have heated up over the 2 minutes and with limited air would have smouldered. The steam from vapor would have disappeared once it reached the surface (on a real humid day it would linger for a time), but the organic material would have produced particulates that would have lingered.

Needless to say a horizontal SFRB testing is not the most environmentally friendly thing that you can do in a desert. The CO2 injections themselves prolly killed stuff that managed to hide underground near the site.

Maybe it's just an issue with the video compression, but it looked to me like the smoke was ONLY coming from the rocks, and not the surrounding sand. Which admittedly is a bit weird, in hindsight.

Yeah that smoke being kicked up was from the radiant heat at the nozzle. The local areas was probably sprayed with water before launch to prevent dust kickup. I don't think it was dust, some of the steam dissipated as it rose up.

[Scotius]

I've noticed some weeds and shrubs growing relatively near the stand. If heat was so high to make sand smoke, any plant matter in vicinity should combust much earlier.

[Moar Boosters]

It's probably just dust being lifted by warm air. Those baby's vibrate a lot when they fire, so bolted to the ground it's going to cause a mini earthquake.

[Norpo]

Geez, I can just smell the rocket fuel at the end.

It's Utah. The desert part. There isn't enough water in the soil to do that. It's dust, raised by the acoustic energy coming out of the SRB.

Are you sure about that?

[vger]

I want me a chunk of that to put on display
