Ops Request 19074-0 "QBF On-Orbit Test" was initiated at 087/11:12:33 to begin the NSSC-1 command 
buffering activity planned for March 28th - April 4th. The QBF Transfer was enabled in the HST486 
at 087/11:12:47. The first QBF SPC load uplink for B59N59S0C was completed at 087/11:22:39. The 
uplinks of QBF loads B60N60T0C and B61N61A0C were completed at 087/11:27:53 and 087/11:57:55 
respectively. Upon AOS at 087/14:34:30, it was verified that the first QBF load, B59N59S0C, had 
been successfully transferred from the HST486 to the NSSC-1. Upon AOS at 087/19:02:54, it was 
verified that the B59N59S0C load was executing in the NSSC-1 as expected. Flight Operations will 
continue to uplink QBF loads at the appropriate time in support of this activity until next Monday, 
April 4th. At that time, operations will switch back to NSSC-1 direct SPC loading.
