I did no such thing!

I only pointed out a retrograde orbit would be useless with an object orbiting prograde. Unless you plan on destroying ISS or just passing really quickly by it...

You loose mass to orbit or use more energy to get the same mass there using a retrograde orbit. That is why they are rarely used.

        It's Retrograde, thus you lose all of the Earth's rotational energy and have to make it up with more fuel... (n/t) - Chris Vancil - 6/10/2003 6:35:30 PM
