Could this be why the ISS was "accidentally" bumped into a new orbit?
But according to the Russian space agency Roscosmos a malfunction on a docked Russian spacecraft caused the International Space Station to shift from its normal orbital orientation while NASA confirmed that the engines of Soyuz TMA-15M – one of two Soyuz spacecraft currently docked at the ISS – unexpectedly fired at 10:27am Central time on Tuesday, pushing the station somewhat out of its expected position.
