I agree with folks who find this step between India and the US a good thing. And working together in space with India is not exactly new. As the Department of State affirms in this fact sheet (March 2, 2006), the "United States and India have been cooperating on space for decades." And in March, the US and India agreed, among other things, to "continue exploring further cooperation in civil space" and "opening up new opportunities for commercial space...." That meant Chandraayan-I and more. (See also this ISRO backgrounder on Indian-US space cooperation.)
शुभ कामनाएँ to Chandraayan-I!
