A major factor in the mission's success was the smooth operation of
the Instrument Pointing System (IPS), which pointed the three
telescopes at their targets, and the Image Motion Compensation System
(IMCS), which sensed small disturbances and compensated for them in
two of the telescopes. "The IPS and IMCS for the first time achieved
operational capacity," Astro-2 Mission Manager Robert Jayroe said.
"In my estimation, the IMCS and IPS teams have done everything but
make the hardware stand up and do a tap dance."
