NIFS Changes
  • Extra ballast to Carrier Frame.
  • Move vacuum jacket O-rings to center section.
  • Lifting fittings to vacuum jacket end plates.
  • Science detector hermetic connector and
    controller.
  • Cold Work Surface plate hole pattern.
  • Pick-off mirror and OIWFS baffle mounts.
  • New closed cycle coolers(?) to reduce vibration.
