The flight of Soyuz TMA-18M to the International Space Station continues on track for a docking early on Friday to mark the arrival of ISS Expedition 45/46 crew member Sergei Volkov and short-duration visitors Andreas Mogensen and Aidyn Aimbetov. The spacecraft blasted off atop a Soyuz FG rocket on Wednesday and entered a low orbit to catch up with the International Space Station through a set of orbital maneuvers that were begun shortly after launch. Docking to the Poisk Module is expected around 7:35 UTC according to the latest ballistics calculation.
