How Many Russian Earth Observation Satellites will be in Orbit by 2015?Space Daily
000 light-years and contains between100 billion and 400 billion stars. The Milky Way is so big that, over billions of years, its mass has captured numerous dwarf galaxies, which contain no more than a few billion stars, as satellites....
Thousands of satellites fly overhead every day, helping us with things like weather forecasts, scientific research, communications, TV broadcasts (and maybe some surreptitious spying). How much do you know about these eyes in the sky?
Types of Satellites You're looking at the world's first geosynchronous satellite, Syncom I. Unfortunately, it stopped sending signals just seconds before it got comfortable in its orbit. No matter. NASA launched Syncom II a mere five months later....

How Satellites Work What's the Difference Between a Satellite and Space Junk? This NASA illustration represents all man-made objects, both functioning objects and debris, being tracked when the image was created in 2009. The image was made from models used to track debris in Earth orbit....
IN 2002, two NASA satellites nicknamed “Tom” and “Jerry” were charting Earth’s gravitational field, as part of the Gravity Recovery and Climate Experiment. As they moved in the same polar orbit, the distance between them was monitored to an accuracy of 10 micrometres, a tenth of the ...
an astronomer at Eötvös Loránd University in Hungary. But it's not the only object to be pulled into Earth's orbit; a host of near-Earth objects and dust clouds are also caught in Earth's gravity. These often-temporary satellites technically qualify as minimoons, quasi-satellites or ...
On February 8, 2022, approximately 40 of the 49 Starlink satellites were reported to have lost altitude, leading to atmospheric re-entry. SpaceX reported that the orbital decay on Starlink satellites was considered to be linked to a geomagnetic storm tha
