  1. Re:GPS Accuracy on Longitude · · Score: 1

    Selective Availability has been turned off for a while now.

  2. Re:What kind of an orbit are they in? on Iridium Satellite Breaks Up Over Arctic · · Score: 1

    Actually, the Iridium satellites are in a low earth orbit. That's why they needed so many of them. GPS satellites are also in a low earth orbit. It's just that there's so many of them you'll always have a few in view. If the Iridium's were in a geosynchronus orbit you'd need a lot more powerful transmitter to get to them.

    It's not a "NASA mission". No NASA money is involved. It's a UK project. NASA is not the only agency that sends stuff into space.

    The Russians (or Soviets) have lost a few astronauts. You can find out more at http://www.guardianunlimited.co.uk/spacedocumentar y/story/0,2763,200523,00.html

  5. Re:Your final prize on NBC Signs Up To Broadcast "Destination Mir" · · Score: 1

    Actually, the USSR space program had several fatalities, including (I believe) the first Soyuz launch. A valve opened during reentry and the guys all died. There was also one launch that had to abort before abort because of a staging problem and they took over 20g! Capsule stopped tumbling down the mountain just before a cliff! Oh yeah, there was also a big explosion on the pad on an unmanned test that wiped out a lot of people, including the "Chief Designer".

    So that's why all those airplanes are always being shot down! Everytime a transatlantic flight gets within 10 miles of the UK the RAF shoots it down! Not to mention what the French do to them! :-)

    Don't you think they'd come up with some agreement so that it could be built in whatever country it comes down in?

    No, it was the "Tower of Babel". Hence, Babelfish .

  8. Re:Moon and Mars missions on The End of The Line for Iridium · · Score: 1

    Nope, not enough propellent for that. They just have station keeping thrusters. Also, these aren't normal communications relay satellites, they're like telephone switches.

  9. Re:Why destroy them all?... on The End of The Line for Iridium · · Score: 1

    You can't use them individually because these aren't a normal communication satellite that just relays anything they receive back down again. These are essentially telephone switching centers in a satellite. They talk to ground stations as well as with each other directly. You can't reprogram them to act like a regular communications satellite, and you can't change the frequencies they use. Sorry.

    Believe it or not, the Ewoks were speaking Urdu, a language spoken in Pakistan.

    What about Serbia? AFAIK, there are (or were) McDonalds restaurants in Belgrade. While it wasn't a "war", we have bombed Belgrade.
