A spacecraft (or spaceship) is a vehicle, vessel or machine designed to fly in outer space.

Spacecraft are used for a variety of purposes, including communications, earth observation, meteorology, navigation, planetary exploration and transportation of humans and cargo .

A space probe is a scientific space exploration mission in which a spacecraft leaves Earth and explores space. It may approach the Moon; enter interplanetary space; flyby, orbit or land on other planetary bodies; or approach interstellar space. Space probes are a form of robotic spacecraft. The Voyager 1 is one of the most famous space probes.

A space station (or orbital station) is a spacecraft capable of supporting a crew which is designed to remain in space (most commonly in low Earth orbit) for an extended period of time, and to which other spacecraft can dock. A space station is distinguished from other spacecraft used for human spaceflight by lack of major propulsion or landing systems. Instead other vehicles transport people and cargo to and from the station.

• As of November 2012 two space stations are in orbit: the International Space Station, and China's Tiangong 1 (which successfully launched on September 29, 2011, after failing in its prior August launch attempt)

The Space Shuttle was a crewed, partially reusable low Earth orbital spacecraft operated by the U.S. National Aeronautics and Space Administration(NASA). Its official program name was Space Transportation System, taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development

A rocket is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellants carried within the rocket before use. Rocket engines work by action and reaction. Rocket engines push rockets forward simply by throwing their exhaust backwards extremely fast.
