How long do Starlink satellites stay in orbit? Starlink satellites are designed to stay in the air for about five years. As the satellites reach their end-of-service date, they’ll be steered into the Earth’s atmosphere, where they’ll burn up. Why do astronomers have a problem with Sta...
How Many Russian Earth Observation Satellites will be in Orbit by 2015?Space Daily
much of Earth passes under a satellite in a polar orbit. Because polar orbits achieve excellent coverage of the planet, they are often used for satellites that do mapping and photography. And weather forecasters rely on a worldwide network of polar satellites, which covers the entire globe ever...

White Sands will relay the signals to a pair of Tracking and Data Relay satellites in orbit 22,300 miles above the Earth. The satellites will relay the signals to the space shuttle. The system works in reverse as well. The orbiter has two systems for communicating with the ground: S-band...
The velocity to keep a satellite in orbit is much higher, known as the orbital speed, which is around 17,000 miles per hour. Anatomy Of A Satellite Attitude Control Satellites need to take accurate measurements while orbiting without any wobbling. Therefore, they are regularly stabilized through...
Skylab 1 in orbit after its repairs -- note the gold sunshade. Image courtesy of NASA The United States placed its first, and only, space station, called Skylab 1, in orbit in 1973. During the launch, the station was damaged. A critical meteoroid shield and one of the station's two...

What prevents satellites, such as the space shuttle, from falling? Which space shuttle carried the Hubble Space Telescope into orbit? How much does a space shuttle launch cost? Is the Soyuz spacecraft reusable? How long is the space shuttle Endeavour?
Electrons circle the nucleus in fixed orbits -- a simplified way to think about it is to imagine how satellites orbit the Earth. There's a huge amount of theory around electron orbitals, but to understand light there is just one key fact to understand: An electron has a natural orbit that...
