Report #8
Star Date: Dec. 22, 1998

The FUSE Project has requested and obtained a change to the FUSE launch date.

NASA will request a launch opportunity in late May 1999 at the earliest, and possibly into June 1999, from Boeing (who controls the Delta launch manifest). An exact planning date will be selected at a later time.

It was our position that the practical, prudent, and realistic approach to mitigate on-orbit operational risk was to provide more test opportunity, as well as reworking the current Inertial Reference Units.

The Project plan is:

  • Complete T-V in mid-January
  • Place the Satellite in the SSDIF (HST Cleanroom) at NASA/GSFC.
  • Remove the gyro for rework at Allied and modify the electrical harness to provide for the ability to utilize three IRU's.
  • Continue to operate the Satellite in the cleanroom from the SCC during February and March.
  • Install the gyros (two from Allied and the third from Honeywell or OSC), and conduct proper electrical/ACS testing.
  • Ship to CCAS/KSC in mid-April.

The satellite environmental test program has been very successful and everyone's hard work has allowed us to uncover the problems which we are now so diligently trying to resolve.
