- From Nzinga Tull's Flash Report:
-- During the today's (07/17/09) 11am briefing on the NCS safing, it was
agreed that no additional NCS re-start attempt will take place immediately.
-- At ~2:40pm, EPS SEs will back-out the taper charge flight software
modifications associated with the NCS restart.
-- Over the next few days, SI SEs will adjust the NCS CPL setpoint to
begin the process of warming NCC interfaces (in preparation for a future re-start
attempt).
