The International Space Station was thrown briefly out of control on Thursday after a newly arrived Russian module malfunctioned, according to NASA.
Officials said the seven crew members aboard weren't in any immediate danger-
But the malfunction has prompted the agency to postpone another highly anticipated test flight to the station by Boeing.
NASA said Thursday's mishap began about three hours after Russia's Nauka module had latched onto the space station, as mission controllers in Moscow were performing some post-docking "reconfiguration" procedures.
The module's jets unexpectedly restarted and inadvertently fired off their thrusters, pitching the entire station out of its normal flight position, leading the mission's flight director to declare a "spacecraft emergency."
Flight teams on the ground managed to restore the space station's orientation by activating thrusters on another module of the orbiting platform, with experts describing the struggle to regain control as a "tug of war."
The Nauka engines were ultimately switched off, and the space station was stabilized.
What caused Nauka's engine malfunction has yet to be determined, but Russia's space agency attributed it to having to work with residual fuel in the craft.
The module had experienced glitches after its launch last week, raising concerns about whether it would dock properly.
There was no immediate sign of any damage to the space station.
