Space is getting pretty crowded -- there are a couple thousand satellites orbiting Earth, not to mention destroyed-satellite debris and at least one zombiesat. Adding new ones is increasingly difficult, because there's only so much room for satellites to sit in specific, geostationary orbits.

In this modern economy, apparently nothing is sacred -- not even the space shuttle is spared the indignity of training its younger replacement. During what is planned to be the last shuttle flight ever, astronauts onboard space shuttle Endeavour next February will test a new docking system

The International Space Station is upgrading its timepiece. An atomic clock constructed by EADS Astrium will arrive at the ISS in 2014, providing the most accurate timekeeping to date in space, better synchronisation of clocks on Earth, and the opportunity to learn a few things about time itself.

It's never happened, and NASA feels confident that it never will. For one thing, astronauts generally don't float free. Outside the ISS, they're always attached to the spacecraft with a braided steel tether, which has a tensile strength of 1,100 pounds. If it's a two-person

Since the first binary code sent from Puerto Rico in 1974, our messages to aliens have been increasingly complicated and cryptic, possibly so much that extraterrestrials won't get what we're saying.

Evasive speed demons may have a harder time avoiding a GPS-enabled speed camera which can capture license plate numbers under any weather condition, 24 hours a day. The new speed cameras in the UK use GPS satellites to help measure cars' average driving speeds over long
