The Ariane 42P, built by Arianespace, was launched from the Ariane Launch Complex at the Guiana Space Center in Kourou, French Guiana. This complex, operated by Arianespace, is located within the Guiana Space Center, which, in its turn, is operated by CNES.
The entire system was managed by the CNES Launch Vehicle System Manager and supported by the Arianespace and JPL/Fairchild spacecraft launch teams.
