Off-point and Power Loss Status of Galaxy 15 The Galaxy 15 satellite continues to drift eastward on a stable and predictable path. We have worked closely with Orbital Sciences Corp, the spacecraft manufacturer, to expand and update the data inputs to Orbital's simulation model based upon the unprecedented operating condition of this satellite, resulting in a revised off-point date. Based on the revised analysis, the estimated window for a Galaxy 15 off-point and loss of power is between 28 November and 29 December 2010.
