Usually a casing containing a relatively slow-burning propellant such as gunpowder to provide thrust.

A payload, in the case of military rockets, usually something unpleasant in an explosive or chemical way, goes at the front end.

Rockets tend to be unguided, with a motor that burns to accelerate the rocket to cruising speed, then cuts out leaving the rocket to follow a ballistic trajectory.

A missile tends to be guided in some way, and the motor burns all the way to impact.

As ever, the distinction is rather blurred as both terms have been in use for many years.

A "rocket" is also what you get from the CO, if you are from Crab Air and you suffer a prang. See also Interview Without Coffee.
