>What's the largest geo sat ever built? I poked around on google, I remembered this sea launch payload from april 26th, spaceway 1 for DIRECTV, which has a mass of 13,376lbs (6067kg), the " heaviest commercial satellite to date:" http://www.californiaspaceauthority.org/html/press-releasesandletters/pr050427-2.html the mass I found for thaicom 4 (iPSTAR-1) is given as "about 6700 kg" or 14,770 lbs; http://www.skyrocket.de/space/index_frame.htm?http://www.skyrocket.de/space/doc_sdat/ipstar-1.htm the heaviest MILSTAR payload I could find is given as 4537 kg (10,000 lbs),milstar 2-3: http://www.spaceandtech.com/digest/flash2002/flash2002-004.shtml there may be one more milstar which could outweigh milstar 2-3: Milstar DFS-6 (USA 169) so currently spaceway 1 is the heaviest GEO.
