Flight Flight is the process by which an object moves, through an atmosphere or beyond it, as in the case of spaceflight. This can be achieved by generating aerodynamic lift, propulsive thrust, aerostatically using buoyancy, or by ballistic movement.

About Rockets A rocket essentially is a container propelled in one direction by exhaust going in the opposite direction. Rockets help spacecraft get into space, stay in space, and maneuver in space. The launch and flight of a rocket are governed by Newton's Laws of Motion.

What Is an Orbit? This article is part of the NASA Knows! (Grades 5-8) series. An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them. A satellite can also be man-made, like the International Space Station.

What is a Satellite? A satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth).ost satellites also work in this zone. Geostationary orbit is the best spot for communications satellites to use, however. This is a zone above Earth's equator at an altitude of 35,786 km (22,236 mi).

satellite In general, a satellite is anything that orbits something else, as, for example, the moon orbits the earth. In a communications context, a satellite is a specialized wireless receiver/transmitter that is launched by a rocket and placed in orbit around the earth. There are hundreds of satellites currently in operation. low-earth-orbit (LEO) satellite system employs a large fleet of birds, each in a circular orbit at a constant altitude of a few hundred miles. The orbits take the satellites over, or nearly over, the geographic poles. Each revolution takes approximately 90 minutes to a few hours.

Definition of 'probe' A space probe is a spacecraft which travels into space with no people in it, usually in order to study the planets and send information about them back to earth. Its rings were discovered by telescope from Earth, but space probes later found that spectacular rings surround some other planets. The Pioneer probes have on board ultra-violet instruments which are measuring light that we can't measure on the earth.

Propulsion Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. There are many different methods. Each method has drawbacks and advantages, and spacecraft propulsion is an active area of research. However, most spacecraft today are propelled by forcing a gas from the back/rear of the vehicle at very high speed through a supersonic de Laval nozzle.
