The International Space Station and many low-Earth orbit satellitescircle the planet in the thermosphere, an atmospheric layer that “plays a crucial role in creating drag on orbital debris,” Parker adds. Drag islike air friction, and it pulls space junk an...
In addition to the moons that come and go from Earth's orbit, there are space objects that NASA calls quasi-satellites, such as the asteroid 3753 Cruithne. These space rocks orbit the sun so similarly to Earth that they stick with our planet throughout its 365-day orbit. The quasi-moon ...
How Many Russian Earth Observation Satellites will be in Orbit by 2015?Space Daily
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 ...
McDowell told Space.com that "many tons" likely splashed down into the ocean. Fortunately, the Starship upper stage is made of stainless steel and not aluminum like satellites and upper stages of many other rockets includingSpaceX'sFalcon 9. The incineration of aluminum is what worr...
