Payload Activities

On DOY 211, the instrument failed to boot up as commanded, and appeared to remain in Safe Mode. This caused all subsequent TCs related to the science run not to be executed, and thus the observation to be lost.

The instrument was regularly operated as part of the routine plan.

Following the completion of the planned tests last week, there has not been any further operation of PFS.
