The launch date for RAX-2 and M-Cubed has slipped two days to October 27, 2011.
According to NASA:
“The launch of the NPOESS Preparatory Project (NPP) spacecraft aboard a United Launch Alliance Delta II rocket is rescheduled to Oct. 27.
Two items have resulted in additional work to be performed on the NPP launch vehicle and this has resulted in the 2-day delay in the launch date. During systems testing, a hydraulic system leak was detected and the cause was found to be a small crack in a hydraulic tube. A replacement tube was manufactured, installed, and retested. All other similar tubes have been inspected and confirmed to be free of any defects.”
