an engine that creates thrust, esp. a small rocket engine used to adjust the attitude or course of a spacecraft in flight
‘Thrusters’ giving rocket action at an angle to the hull will allow for manoeuvring.
The coarse adjustment was the powerful thrusters back and front which fixed final velocity by their accelerative and decelerative force.
The more massive our Gemini capsule becomes the more difficult to accelerate; and you can’t really push it up to the infinite-mass stage without infinite force in the thrusters to do the job.
‘Make ready for touchdown. Cut outer jets. Full boost on central thruster...’ Van Noon’s voice continued precisely above the wave of sound as the mammoth ship loomed in the air above them.
Speaker ran the big fusion motors up to full power. He tilted the flat thruster discs out of the plane of the wing, lining their axes along ship’s aft, and added their thrust to the rockets. The Liar backed into the system blazing like twin suns, decelerating at nearly two hundred gravities.
They could not possibly lift the weight of a man, even against Rama’s modest gravity. Could an EVA thruster be sent up on automatic control, carrying only a rescue line? He had tried out this idea on Sergeant Myron, who had promptly shot it down.
Whitbread coasted slowly inward. He rode a space-to-space taxi, the cabin a polarized plastic bubble, the short hull studded with ‘thruster clusters’—arrays of attitude jets.
Montgomery Scott, with some unexpected flair for drama, had maneuvered to keep the starship from Kirk’s sight until the last possible moment. Then, he had used the lateral thruster to nudge their travel pod into a sweeping turn, bringing Enterprise into glorious full view.
‘I don’t want that gas spurting out and acting like a rocket thruster,’ Hazard explained to her back. ‘Besides, it’s an old submariner’s trick to let the attacker think he’s caused real damage by jettisoning junk.’
Franklin could see little puffs of vapor from a personal thruster as the figure sped toward him. Delvientos spoke and flew at the same time.
Mercury’s escape velocity is over four kilometers per second, and there’s no atmosphere to speak of. We are coming in at just over orbital velocity, without a thruster pack, and there can’t possibly be enough orbital tethers for this crowd. But the Mercurials have come up with a solution: the equatorial maglev track.
Her cockpit shudders. Daren raises his hammer and plunges it down. Onyii powers her thrusters to lift her up, then backward, just out of the way of his strike.
