EGP is a 2.2m sphere covered w/planer mirrors and corner cubes and the like
the flashes you see are reflections of sunlight on theese mirrors as EGP 
tumbles (there are no control ability on egp) and thats why it flashes.

I believe you can also hit it w/laser beams and the corner cubes will 
bounce them back....but i'm not 100% sure on this...

its a cool satellite to observe...i've only seen it telescopically, i am 
dieing to go to a dark site and look for it naked eye (the flashes are about 
4th magnitude and its non-flash mag is about 8 maybe...)
