A Boeing Delta II rocket launched the latest additions to the Iridium satellite constellation Monday from Vandenberg Air Force Base, Calif. at 9:44 a.m. PST.

The Delta II launch vehicle deployed five satellites into low-Earth orbit to serve as spares for Iridium Satellite's worldwide communications network. Monday's launch of IS-1 marks the first Delta mission of 2002 and the 101st Boeing Delta II mission since 1989.
