A little over three hours after docking was complete, cosmonauts Oleg Novitsky and Pyotr Dubrov were in the Zvezda module to which Nauka docked, preparing to open the hatch between the two vehicles. Then, at 12:45 p.m. EDT (1645 GMT), thrusters on Nauka fired "inadvertently and unexpectedly," according to NASA spokesperson Rob Navias. As a result, the space station temporarily lost what engineers call "attitude control," which is quite rare, Navias noted.

"The crew is not in any danger, never was in any danger and attitude control has been regained," Navias said during a live broadcast begun after the station regained its position.

The unplanned thruster firing caused the orbiting laboratory to tilt by about 45 degrees from its proper orientation before the station was able to right itself, Navias said. All told, the station lost attitude control for a total of about 47 minutes, according to NASA officials.

The space station automatically recognized that Nauka's thrusters were sending the orbiting laboratory askew and ordered the Zvezda module to fire its own thrusters to compensate, a process completed by the robotic Russian Progress 78 cargo ship, which is also docked to the space station.

After the station regained its proper position, Nauka's overseers in Russia began work to ensure the thrusters would not fire mistakenly again, according to NASA. That command was successfully implemented as the space station flew over command stations in Russia.
