The most important assignment of the US military space community is ensuring that there is no interruption to the critical services that on-orbit constellations provide, such as precision navigation, protected communications, and overhead sensing, says Gary Payton, Air Force space czar. “We have several critical missions that serve the entire nation; some missions serve the entire world. Our top priority is [their] continuity,” he told reporters Feb. 4. Beyond just ensuring that these constellations continue to function properly, this task also involves upgrading their capacity in a manner non-disruptive to the users, he said. For example, the Air Force last year placed the last Global Positioning System Block IIR navigation satellite into orbit. In May, it plans to launch the first of 12, more capable Block IIF spacecraft into space. Then, in 2014, it will smoothly transition to the even more powerful Block IIIA series.
The Air Force has spent more than two years studying cancer risks to Airmen who work with the service's intercontinental ballistic missiles. Now lawmakers in Congress are placing fresh scrutiny on the issue and have prepared legislation that would direct the service to clean silos and launch facilities.
