In the pre-dawn hours on August 25th, 2003, the Space Infrared Telescope Facility (SIRTF) was launched from Cape Canaveral Air Force Station into a "first of its kind" solar orbit. The launch aboard the Delta II 7920H was nearly flawless, with the launch vehicle meeting all attitude requirements on the way to injecting the SIRTF Observatory towards the prescribed launch targets. This paper analyzes the "as flown" trajectories of the Observatory, the Delta 2nd Stage, and the Observatory's Dust Cover, and compares them to pre-launch predicts. Impacts that the solar orbit and the evolving mission design have on mission operations, both during the nominal mission and beyond, will be discussed with special attention paid to the "life-limiting" elements of the solar orbit.
