Thrusters on...

A.J.! A.J., the thrusters!

Pull the thrusters! Lev, look out!

Mayday, Houston, mayday! We've lost R.C.S. thrusters!

The Tiburon also uses electric powered thrusters.

I'm ready to fire my thrusters any time.

Fires on your right, Sharp! Reversing the thrusters!

We got no time! Initiate thrusters on my mark!

We have these new generation suits with directional accelerant thrusters.

Mayday, mayday! I've lost main thrusters. Get 'em back up!

Houston, do you read? This is Freedom. Check your thrusters.

Come on! Let's get ready to initiate thrusters! Let's go!

You can walk around, but use your thrusters so you can work easier.

We turn the thrusters off, we jump this thing, we float right over it.

I've got bright lights and noisy thrusters any animal with any sense is going to be long gone.

You'll then use lunar gravity and burn your thrusters, slingshotting you around the moon, coming up behind the asteroid.

And it's got these jet thrusters up in front that it'll use in a moment, and a little light.

The Johnson Sea Link (whirring noise) which you can probably just barely hear here, uses electric thrusters very, very quiet.

Throw the jet thrusters off exactly when we jump. And then we're gonna put them on, and we gonna go down nice and slow.

They have their own thrusters going, but they also are catapulted off, so they can be really accelerated quickly off of the flight deck of this carrier.

So now it's hovering at about 40 meters, and it's constantly adjusting the angle, the pitch and yaw of the main engine, and maintaining roll with cold gas thrusters.

When I'm sitting in a submersible though, I know that I'm not unobtrusive at all I've got bright lights and noisy thrusters any animal with any sense is going to be long gone.

I proposed using an optical lure attached to a camera platform with no thrusters, no motors, just a battery powered camera, and the only illumination coming from red light that's invisible to most deep sea animals that are adapted to see primarily blue.

I saw chains of jellyfish called siphonophores that were longer than this room, pumping out so much light that I could read the dials and gauges inside the suit without a flashlight and puffs and billows of what looked like luminous blue smoke and explosions of sparks that would swirl up out of the thrusters just like when you throw a log on a campfire and the embers swirl up off the campfire, but these were icy, blue embers.
