National news reports Discovery visually sighting HST at about 75 miles distance sometime earlier today, with a join=up this evening. Heavens-Above gives visible passes (this evening) for the pair (Phoenix, Arizona) separated by about 15 minutes. That figures (in my head) to be about 4K miles apart. Could someone please make these numbers add up? Thanks, Robin Thomas A.
