escape velocity:
The minimum speed that an object at a given distance from a gravitating body must have so that it will continue to move away from the body instead of orbiting about it.
orbital velocity:
The velocity a rocket must achieve to establish an orbit around a body in space.
rocket:
A device that expels gas in one direction to move in the opposite direction.
rover:
A small robotic space probe that can move about the surface of a planet or moon.
satellite
An object that revolves around another object in space.
space probe:
A spacecraft that has various scientific instruments that can collect data, including visual images, but has no human crew.
space shuttle:
A spacecraft that can carry a crew into space, return to Earth, and then be reused for the same purpose.
space station:
A large artificial satellite on which people can live and work for long periods.
thrust
-The reaction force that propels a rocket forward-
velocity
-Speed in a given direction-
