They did a good job, he thought as he tapped his jet thruster controls to push himself back to the surface.

Her rudder and the great jet thrusters lifted out of the water into the night.

The RCS provides propulsive forces from a collection of jet thrusters and controls attitude of the space shuttle.

The firing of its jet thrusters is set for Oct. 15 to adjust the craft's aim on Jupiter.

Directional yaw control is gained through a vented, rotating drum at the end of the tailboom, called the direct jet thruster.

This is augmented by a direct jet thruster and vertical stabilisers.

In Dr. Masri's scheme, the random energy is provided by jet thrusters mounted on the roof.

The propellants for the jet thrusters fired in maneuvering the craft were monomethyl hydrazine combined with nitrogen tetroxide.

This is augmented by a direct jet thruster (which also provides directional yaw control) and vertical stabilizers.

Dr. Pacini said the $600,000 experiment had proved researchers' theory that a satellite could orient and stabilize itself without jet thrusters.
