Arabsat 4A

 2006-006A


EADS Astrium Eurostar 2000+ satellite; 4B to follow. Launch by ILS Proton 535-11/Briz M 88515 Comms payload by Alcatel. Also called BADR-ONE.

Briz-M failed in transfer orbit; MES-2 ended 3min10s early. Planned duration was 21 min. Since the satellite contract was for on-orbit delivery, the satellite was presumably owned by Astrium in orbit. After the failure, a European insurance group took ownership (J. Oberg, http://www.nbcnews.com/id/11999597/ns/technologyandscience-space/t/arabsat-bites-dust-dashing-hopes)

Mass 3341 kg full 1520 dry 2.5 x 1.8 x 2.9m with 7.5 x 32.0 x 4.5m deployed.
