At NASA Kennedy Space Center's Launch Pad 39A, teams have closed
the rotating service structure (RSS) around space shuttle Atlantis.
The RSS provides access to the shuttle and helps protect the
spacecraft from the elements.
Engineers have reviewed data from a lightning strike nearly half
a mile from the pad on Wednesday. No issues have been seen due to
the strike. An engineering team also will perform a visual
inspection walkdown at the pad.
Friday, technicians connected the forward reaction control
system quick disconnects and check them for leaks, over the
weekend, teams will connect and check the quick disconnects for the
auxiliary power system.
Meanwhile, technicians in Kennedy's Orbiter Processing
Facility-1 prepared Endeavour on Friday for this weekend's purging
of the vehicle's orbital maneuvering system chemicals.
