Confusion and speculation
While missions of X-37B remain obscure, the Union of Concerned Scientists (UCS), headquartered in Cambridge, Mass., criticizes the program as a less-than-cost-effective way to conduct space activities.
UCS space experts assert that, while the space plane is versatile and capable, there are better, more efficient and more cost-effective ways of carrying out the X-37B's possible missions.
"And because it is an Air Force project and its details are classified, the plane has generated confusion, speculation and, in some cases, concern about its actual purpose" a UCS document issued prior to the OTV-3 mission launch said.
