On Vanguard One, I found this site:
http://home5.swipnet.se/~w-52936/index20.htm It's got an ongoing odometer for Vanguard One, which, as I type this, has done some 11,469,717,200 KM in space... Andre |

Can you imagine what it would be like for a returning NASA astronaut from the ISS to have Vanguard II sitting in his lap, just like the Hawk model he had of it when he was a kid?: http://www.ebay.com/itm/1966-Hawk-Mo...-/380361685341 Had three of those as a kid, broke the antennas off on every damn one of them.

I notice the orbital lifetime has dropped a bit from what it was in the books I had as a kid, where it was supposed to be 12,000 to 20,000 years. Has anyone actually figured out what the orbital lifetime of a satellite in GEO is before air drag brings it down? Does it come down first, or the Sun turn into a red giant and eat the Earth first? :-) Pat |

Has anyone actually figured out what the orbital lifetime of a satellite in GEO is before air drag brings it down? Tidal and gravitational effects from the lumps and bumps on the Earth dominate at that altitude. Anything below geostationary slowly gets energy sucked out and spirals down, anything above gets energy pumped in and will drift further out which is one of the reasons the graveyard orbit for old satellites is higher than geostationary. It's the same effect that is making the Moon get further away and will drastically lower property prices along the Mrtian equator when Phobos eventually drops in. Anthony |

But ISS isn't one of those things, given that your plan would probably cost more than building it in the first place. the first multinational long term operational space station, and likeky the last is not historic? |
