How do you test a new kind of rocket engine? Step 1: Bolt it to a trailer in the middle of the Mojave Desert. Step 2: Vroom! In this case, NASA is firing up the 5M15, which runs on compressed liquid methane. The odorless substance has multiple advantages over conventional rocket propellants: It's cheaper, it requires much less insulation, and it exists on several planets NASA hopes to travel to — Mars, here we come. That means astronauts could collect their own fuel for the trip home. Bonus rocket science: Those glowing figure eights in the blast stream are called Mach disks, after the guy who lent his name to the speed of sound. They're shock waves, created as the expanding fuel hits the higher atmospheric pressure outside the nozzle. If part of this blast weren't obscured, you could take the number of Mach disks (we count seven) and multiply by the speed of sound — about 758 mph at the 1,300-foot altitude of this test — to estimate the speed of fuel exiting the engine. Just don't get too close.

wow. i gotta pick up my jaw from the floor. this is going to be amazing to see liftoff.

That was cool as hell!

MiSo · 09-03-2007, 06:47 PM

i replayed it a few times just to hear the sound of the rocket. amazing!

Baraka_Guru · 09-03-2007, 06:54 PM

The last time I saw something that cool was on Battlestar Galactica, but that was fake!

Awwh, I was hoping some redneck had that badboy hooked up to an old Dodge Charger.

(thinks)

What the hell happened to pulse detonation engines, anyway?

I think that you could apply this new technology to pulse detonation engine technology...eventually anyway.

Think of it: methane and pulse detonation.

....it would be like a farting rocket.

Pulse detonation...is that the controlled nuclear detonation rocket?
