Satellite

In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon.

The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth. Some satellites, notably space stations, have been launched in parts and assembled in orbit. Artificial satellites originate from more than 40 countries and have used the satellite launching capabilities of ten nations. About a thousand satellites are currently operational, whereas thousands of unused satellites and satellite fragments orbit the Earth as space debris. A few space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, Vesta, Eros, Ceres, and the Sun.

Satellites are used for a large number of purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and research satellites. Space stations and human spacecraft in orbit are also satellites. Satellite orbits vary greatly, depending on the purpose of the satellite, and are classified in a number of ways. Well-known (overlapping) classes include low Earth orbit, polar orbit, and geostationary orbit.

Satellites (song)

"Satellites" is the first single by September from her second album In Orbit and is the first single released under her contract with Catchy Tunes. The single was a success in Sweden and Finland and was later released in variety of countries worldwide, such as Poland, Romania, Spain, Israel, the United Kingdom and the United States, being September's first international release. "Satellites" is considered September's second biggest hit to date (after "Cry for You"), becoming a hit in almost all countries it was released in.

Portuguese television network SIC used the song to promote its now discontinued WAP service, SIC Música. This helped the song gain popularity in Portugal resulting in it becoming a hit, being one of the most played songs on Portuguese radio stations in 2007.

Usage in media

The song was used by Portuguese television network SIC as a promotional song for the now discontinued WAP service SIC Música. It was also used in the Portuguese show Floribella.

Stunt

A stunt is an unusual and difficult physical feat or an act requiring a special skill, performed for artistic purposes usually on television, theatre, or cinema. Stunts are a feature of many action films. Before computer generated imagery special effects, these effects were limited to the use of models, false perspective and other in-camera effects, unless the creator could find someone willing to jump from car to car or hang from the edge of a skyscraper: the stunt performer or stunt double.

Types of stunt effects

Practical effects

One of the most-frequently used practical stunts is stage combat. Although contact is normally avoided, many elements of stage combat, such as sword fighting, martial arts, and acrobatics required contact between performers in order to facilitate the creation of a particular effect, such as noise or physical interaction. Stunt performances are highly choreographed and may be rigorously rehearsed for hours, days and sometimes weeks before a performance. Seasoned professionals will commonly treat a performance as if they have never done it before, since the risks in stunt work are high, every move and position must be correct to reduce risk of injury from accidents. Examples of practical effects include tripping and falling down, high jumps, extreme sporting moves, acrobatics and high diving, spins, gainer falls, "suicide backflips," and other martial arts stunts.

Stunt (gridiron football)

A stunt in American football and Canadian football, sometimes called a twist, is a planned maneuver by a pair of players of the defensive team by which they exchange roles to better slip past blockers of the offensive team at the beginning of a play.

The purpose of a stunt is to confuse opposing blockers, which is an aid to the defense in rushing an opposing forward pass or kick. The main weakness of a stunt is that it is more vulnerable than average to running plays by the opposing team. In most cases, the defense will not use a play incorporating stunting if it expects a running play from the offense.

There are two main types of stunts. In one, a line player, who would otherwise try to charge forward, instead drops back, and a nearby linebacker or defensive back charges forward instead. In the other, which is known as cross-rushing, line players, instead of charging straight ahead, cross paths. One of them may follow a looping path that goes behind the other before moving forward (in which case the stunt is called a "loop"), or one may wait for the other to penetrate slightly first, and then cross behind, their paths angling across each other. In some variants, a rushing player will run around more than one rushing teammate.
