KU-band electronics modules failed POST. After rebooting: no change. Rendezvous radar functionality affected. Ascent data and video imagry of leading edges will be routed through ISS and review will occur after Day 3. Pieces of the current failure mode have occured, however, never have ALL the failures occured simultaneously.
Since the KU-band communications are down, they’ll have to use alternative methods to get command, voice & video data to and from the shuttle. They probably could use flag signals or something.
On docking day they’ll probably have to get one of the guys on the ISS to suit up and go outside to guide the shuttle in (you know like they have somebody callin’ the shots to back a semi into the loading dock). I imagine he’ll have a couple of those flashlights the ground grew uses to guide airliners around to and from the boarding gates.
Maybe the failures are due to the intense solar activity today.
