This figure shows an exploded view of the ROSAT satellite along with the launch configuration. ROSAT was launched into orbit by a Delta II rocket which required that the solar panels be stowed. Once in orbit, the solar panels, mirror doors for both the XRT and WFC, and antenna were deployed. [ROSAT exploded view]
