The Russian space agency, Roscosmos, has completed its investigation into the Soyuz launch anomaly last month that resulted in the launch abort and emergency landing of the spacecraft, in which Expedition 57 crew members Nick Hague of NASA and Alexey Ovchinin of Roscosmos were safely returned to the ground. The investigation concluded that an abnormal separation of one of the four first stage rocket engines caused the engine to hit the second stage rocket, leading to a loss of stabilization.
