Hi Ben, >There was a question a ways back: will the ISS and MIR ever appear in the >same sky in one night? And I beleive the answer was no, they are on opposite >sides or earth, and whenever on is in the morning, the other is in the >evening. > Well, today, May 1 200, both MIR and ISS are in the evening, just 2 >minutes apart! It seems unusual to me (are they gonna colide?!). However, I >suspect it to be from the 'lagging' of the ISS. It has dropped considerably. >(Feeew! They're at different heights!) Right today, May 2, the two objects passed only 47 kilometers from each other at 0617 UTC to the north of Hawaii.
