Tracking
Did you know there are over eight thousand artificial objects orbiting
Earth? Over 2,500 are satellites, operative and inoperative. The
remaining objects are orbital debris: parts such as nosecone shrouds,
lens, hatch covers, rocket bodies, payloads that have disintegrated or
exploded, and even objects that "escape" from manned spacecraft during
operations.
Satellites
There are all kinds of satellites orbiting the earth today each serving
a different purpose. Some satellites provide communications like
telephones and television while other tell you where you are on earth
like the Global Position System. NASA also uses satellites to learn
more about earth and about the deepest reaches of space.

Orbital Mechanics
In 1609, Johann Kepler published his three laws describing planetary
motion. Soon after this, Isaac Newton postulated that there is a force
of attraction between any two objects, called gravitation. In 1687,
Newton then published his greatest work, Principia, which described the
three laws of motion. These laws form the basis for all we know about
how an object's motion is affected by gravity.
