In general, the higher the orbit, the longer the satellite can stay in orbit. At lower altitudes, a satellite runs into traces of Earth's atmosphere, which creates drag. Thedragcauses the orbit to decay until the satellite falls back into the atmosphere and burns up. At higher altitudes, ...
In the more than five decades following the launch of Sputnik, satellites, as well as their budgets, have tended to get bigger. The United States, for example, has spent $200 billion on its military satellite program since its inception and now, despite the investment, has a fleet of aging...
In October 1957, the Soviets finally proved Newton correct when they launched Sputnik 1 -- the first artificial satellite to orbit Earth. This kick-started thespace raceand initiated a long-term love affair with objects designed to travel in circular paths around our planet or other planets in...

The word "satellite" is thrown around a lot these days, but in basic terms, it just refers to any object sent to live in our planet's orbit to perform a designated task. We have communicationssatellitesto make our cellphones work, navigation satellites to make Google Maps give us correct...
A GPS satellite Photo courtesy U.S. Army At this point, you could confidently tell someone you want to impress that GPS works via trilateration. But you should be prepared for the follow-up question: How does the GPS device know the distance to those GPS satellites? As it turns out, ...
How does its orbital speed compare to that of other solar system planets? How fast you need to move to keep in a circular orbit around another body is dictated by how far the two bodies are separated from each other. Planets closer to the Sun are orbiting faster than Earth, with Mercury...
How does satellite Internet work? Satellite Internet works in a similar way to satellite TV. It doesn't use cable systems or telephone lines; it utilizes geostationary satellites to deliver Internet signals to your home. It's essentially wireless broadband beamed down from satellites in orbit or ...
A specific point in space exists where a satellite can be placed in orbit such that it appears motionless from the ground. In reality, the satellite is circling the Earth at the same pace as the Earth’s rotation. This results in the satellite completing one orbit around the Earth in preci...
