Quake3World

0 - 60 MPH = 4.1 seconds
0 - 100 MPH = 7.5 seconds
0 - 200 MPH = 14.9 seconds
0 - 500 MPH = 30.4 seconds
0 - 1300 MPH = 71.3 seconds
0 - 2000 MPH = 90.6 seconds

Veyron? Pfft...fag.

The audio on re-entry is cool.

The extreme decrease in speed is what surprised me. Very cool. Thanks.

after separation, it was tumbling around and yet it was still picking up speed at some point, wtf.

Those boosters are ejected at quite the altitude. I always thought they were dropped much earlier. I also wonder if they know exactly where they are going to crash or if there's just a bit of luck involved with that.

I don't think they work with luck.

Well, I'm sure they know how to make sure it doesn't crash on some house or something, but if they know exactly where it's going to plunge down in the ocean or if that could be anywhere within a 1000 mile radius.

well, they monitor the weather at all times so I'm betting their prediction is no more than a 50 mile diameter at most.

There was a video of some amateur rocket that was sent up at what seemed to be the same height (give or take a few miles) and was retrieved a couple of miles away (if not closer, can't remember the numbers). That was a much lighter object mind you.

Also , if you look at the end of the video , you'll notice that both side boosters didn't end up too far from each other, so any random variables other than weather can be pretty easily ruled out from having any significant effect.

Yeah, you can also see how both are spinning at exactly the same rate, they're pretty much in sync, I doubt that's coincidental.

on second viewing, those rockets ended up freakishly close, so I'm betting their prediction is super tight.

plus you can see land objects in the distance , which looks to be no more than 20 miles away. I'm sure they wouldn't risk that without being pretty damn sure of themselves.

Very cool vid

The video of Mr Carmack's latest launch is really cool too.

The rocket seems to tumble quite a lot. Is that intentional?

The audio is also fascinating. I was wondering with the other video as well, what exactly are we hearing? At 95km altitude, there's no air is there? Then the audio can't be moving air particles. Is it parts of the rocket resonating into the camera we hear?

The sound of it coming down is absolutely awesome as well. I can understand Carmack being thrilled by this stuff. It's far more spectacular than videogames

Ah, I want this on my car:

Those things are STUPID loud in person. I live a few hundred yards down the road from the university's aeronautics research department and every so often they fire off an engine while I'm home. There was one I remember them setting off that was literally deafening. Even knowing what was going on, it was scary being completely overcome by white noise.

I would guess "yes" since that would give it a more predictable trajectory on the return.

and fyi, THIS is the video I was referring to, and as a matter of fact it was retrieved "750 meters from the launch site"... and it seems that the spiraling has some kind of gyro effect that keeps it steady.

Or maybe it was done, to somewhat stabilize the video recording so it's at least video taping the ground at all times.


edit:

oh you said tumble ...no on the tumble, yes on the spiral... the tumble is prolly because of the thin atmos. up there rendering whatever aerodynamic design it has, useless for a short period.

it's the weird jangling noises in the OP video that got me. you don't usually hear ascents, other than from the ground

It's totally random bro they just shoot that shit up there and let it fall out of the sky where ever, fingers crossed just hoping for the best.
