... are nearly 6,000 satellites in orbit. Around ten countries have launched satellites, but often a country will have a satellite launched on someone else's rocket. There are about 20 countries with satellites in orbit ...
... to speed off in a straight line, and Earth's attraction, which results in pulling the spacecraft back into a circuit of the Earth. At the lowest orbital altitudes, there are some very thin traces of atmosphere which will eventually cause a satellite's orbit to drop lower. Beyond this low orbit regime, a satellite can remain in orbit forever.

... very steady in orbit. Periodically, however, it must propel itself back up to the preferred operating altitude that gradually decreases because of the influence of the small amount of atmospheric gas in the ...

... . So that means in a 24-hour day, if you look down from orbit, you get to see 16 sunrises and 16 sunsets—and they are all particularly beautiful in space

... cloud that became the Sun avoided being pulled in by our new Sun's growing gravity, yet were close enough to be caught in its orbit. Slowly they began to draw themselves together ... moons, we believe that water can be found on them as well, if, their atmospheres are cool enough to allow water to form, and thick enough to keep gases like oxygen ... there is some evidence that ice may exist at Mercury's poles in the bottoms of some deep craters, we are generally unlikely to find water or ice on those planets that ...
... orbit and to maintain a space orbit. There is a range of speeds at which the different satellites travel. Because of the laws of physics, the faster we travel the higher up in space we are. So if we want to put a satellite in a different orbit, we make sure that it has different speeds and ...
One of the most significant effects of being weightless in space is on the balance system. When astronauts first go into space, many suffer from ... . This lasts for a day or two, until their balance systems get used to being in space. When they come back to Earth, they again have similar problems until their balance systems now get used to being back in the gravity of Earth. The astronauts take motion sickness medicine to treat space motion sickness ...
