• SpaceLab Pallet installation on the LAB complete.


• Komparus removal in the FGB complete. Komparus will be returned on 6A for repair. A new Komparus unit will be launched on 4P.


• KURS test complete.


• CCAA is in Dual Operations.


• KuBand was parked during SLP installation due to interference concerns.


• BGA 4B Latch 2 troubleshooting was not successful. The BGA was commanded to position 177.087. Phalcon tried twice to latch the pin with no joy. The BGA was then commanded to position 176.987 and latching attempted with no joy. The array was then placed in auto track mode to ensure the pin was not stuck in the latched position. The BGA still exhibited the high motor currents indicating the pin is still partially deployed.


• UHF Antenna installation complete.


• Initial SSRMS deployment procedures complete. The crew removed the 4 jackbolts with no anomalies. Final boom deployment will occur later today by the station crew.
