But it shouldn't unduly affect mission operations, according to the agency. NASA's technology-demonstrating Advanced Composite Solar Sail System (ACS3) has a bent boom in Earth orbit, a newly ...

While NASA revealed that the data gathered since the sail deployment is proving to highly valuable, it added, "The mission team predicts the slight bend in one of the four booms will not inhibit the ...

After one or two months of prep in space, the microwave-sized craft will unfurl its 30-foot sail along four booms or arms made from carbon fiber and polymer. Once unfurled, photons from the Sun ...
