The Arabsat-4 spacecraft are based on the Eurostar-2000+ version of the Eurostar satellite family. Both satellites received the names Badr-1 and Badr-4 respectively in February 2006. Badr 1 did not reach its planned orbit, when the upper stage of the Proton-M Briz-M (Ph.3) launch vehicle failed. After evaluating a lunar fly-by maneuvre to rescue the satellite, Badr 1 was deorbited on 24.03.2006 over the pacific.
