“Mission control teams corrected the action and all systems are operating normally,” US space agency Nasa said.
This was done by activating thrusters on other modules of the ISS. An investigation is now under way.
US and Russian officials stressed that the seven crew members aboard the space station were never in any danger.
Nasa officials said Nauka’s jets started firing uncommanded at 12:34 EDT (16:45 GMT) “moving the station 45 degrees out of attitude”.
The Russian Zvezda segment and a Progress freighter then responded to push the station back into its correct pointing configuration. The incident was over by 13:29 EDT.
“Those guys were rock stars again and got us back in attitude control. That also shows you what a robust vehicle we have, and our ability to take these contingencies, recover from them and move on,” he told reporters.
Communications with the ISS crew were lost for two periods, of four minutes and seven minutes, during the incident. However, the US agency said that the astronauts were safe. They “really didn’t feel any movement”, it added.
.@Space_Station crew members are safe and will scrub their schedules for today in order to focus on recovery efforts following the unexpected loss of attitude caused by the Russian Nauka module's thrusters firing.

“We wanted to give the ISS programme time to assess what had happened today, to determine the cause and make sure that they were really ready to support the Starliner launch,” explained Steve Stich, the manager of Nasa’s commercial crew programme.
“Right now the earliest opportunity would be Tuesday, 3 August, which would be a 13:20 EDT (17:20 GMT) launch.
The 13m-long, 20-tonne Nauka was earlier attached to the rear of the orbiting platform, linking up with the other major Russian segments on the station.
The module should have launched in 2007, but the vessel suffered repeated slips in schedule, in part because of budget difficulties but also because engineers encountered a raft of technical problems during development.
Even after it launched from the Baikonur Cosmodrome in Kazakhstan a week ago, it experienced propulsion issues that required workarounds from controllers in Moscow.
The new module will result in a significant boost in habitable volume for the ISS, raising it by 70 cubic metres.
In addition, the module carries with it a large robotic arm (ERA) supplied by the European Space Agency (Esa).
Nauka’s installation comes just as Russia has been questioning its future role in the ISS project.
Moscow officials recently warned about the more-than-20-year age of some of their on-orbit hardware and intimated the country could pull out of the station in 2025. And Russia has shown little interest in joining the US-led lunar platform, known as the Gateway, which will be assembled later this decade.
