In the last 50 years, human beings have launched thousands of artificial satellites into space. When one of these stops working, it usually falls back toward the Earth and burns up in the atmosphere. Satellites at high altitudes, however, sometimes remain in Earth’s orbit. Later, they may fall apart or explode into thousands of smaller pieces. The higher the satellite, the longer it stays in orbit, and the more likely it is to break apart. The pieces may stay in orbit for years, decades or even centuries.

If you remember, not a long time ago we had an article talking about NASA’s plans to send a satellite to space which could capture pure Sun energy and resend it to Earth in the form of microwaves.

This Friday, John C. Mankins, a former NASA employee who is an expert on space solar power will make a big announcement about a potentially huge alternative energy breakthrough. The basic idea is that satellites in space will collect solar energy and beam it down to the earth.

CAPE CANAVERAL, Fla. (AP) - Astronauts bound for orbit this week will dabble in science fiction, assembling a 'monstrous' two-arme ...

Space agencies including NASA have agreed to use their next generation of satellites to help monitor climate change, the United Nations weather agency said.

The Pentagon has released a report recommending a solar power station be sent into orbit to see if electricity can be beamed to earth.

If you drive a car - and you know who you are - you have invariably come upon the dreaded dilemma of refueling. When the needle on your gas gauge wavers over the unseemly 'E,' you have to ask yourself one question - Do I stop at the next gas station or press on, hoping for a fuel oasis somewhere down the road? But what if you need to motor somewhere three billion-plus miles off the beaten path - somewhere where neither regular nor premium unleaded have so far feared to tread?

Not content with littering the planet, humanity now seems hell bent on making space a dumping ground too. According to a recent report, the number of objects in Earth orbit have increased steadily and today there are an estimated 35 million pieces of space debris.

NASA employees tested the BMW Hydrogen 7 luxury automobile for 8-weeks, which runs off the same fuel as the Space Shuttle, before the successful launch of the Endeavour on Wednesday.
