Attempts by Russian ground controllers to regain control of the Progress have been unsuccessful, and they have said they will not be able to regain propulsive control of it. As a result, the Progress currently is expected to reenter Earth’s atmosphere within the next two weeks. Russian ballistics specialists, working in conjunction with flight controllers in Mission Control Houston and ESA, are continuing to track the vehicle’s path and will provide updates on its anticipated reentry date. The United States Air Force Joint Functional Component Command for Space’s Joint Space Operations Center is also tracking Progress, performing conjunction analysis, and providing warning of any potential collisions in space to ensure spaceflight safety. The break up and reentry of the Progress poses no threat to the ISS crew.
