Last week, a Russian module accidentally pushed the International Space Station out of place. Now, a NASA flight director has revealed that the event was more serious than NASA initially reported. 

On Thursday (July 29) morning, Russia’s long-awaited research module Nauka docked with the space station. But a few hours later, the module accidentally fired its thrusters, briefly tilting the space station and causing it to lose what engineers call “attitude control.”
