SDO Weekly Report for June 29, 2011

The FOT discovered a discrepancy between the Inertial reference Units (IRU) alignments and scale factor presently onboard in the Single Board Computer (SBC) Table 73 and those which were supposed to be in use. The differences are small, and the effects minimal, so the plan is to do nothing at this time, since time out of science mode (~ 1 hour) is required to validate an alignment table change per current procedures. The current plan is to wait until the next eclipse season this fall to correct the problem. An audit of all other alignment parameters has been started to look for any other discrepancies.

The FOT completed simulations for the momentum unload scheduled for 7/6 at 19:17 GMT. The Command Authorization Meeting (CAM) will be held on 7/5 after the weekly planning meeting.
