Sea Launch successfully launched the DIRECTV 7S broadcast satellite to orbit on May 4, 2004. The Sea Launch Zenit-3SL rocket lifted off at 5:42 am PDT (12:42 GMT) from the Odyssey Launch Platform, positioned on the equator in Pacific waters. All systems performed nominally throughout flight. The Block DM-SL upper stage inserted the 5,483 kg (12,063 lb.) DIRECTV 7S satellite into geosynchronous transfer orbit, on its way to a final orbital position at 119 degrees West Longitude.
This mission was Sea Launch's 10th consecutive success. The satellite is the heaviest commercial spacecraft launched successfully to orbit as of this date.
