The issue caused the space station to lose 'attitude control' for about 45 minutes.

Yesterday's unexpected tilting of the International Space Station was caused by a software glitch, according to Russian space agency Roscosmos.

A new Russian module dubbed Nauka arrived at the space station Thursday morning (July 29).

However, while the module's arrival appeared to go smoothly, about three hours after docking, the module unexpectedly began firing its thrusters in an incident that caused the space station to tilt from its typical position for about 45 minutes in what engineers call a "loss of attitude control.".

"At the moment, the station is in its normal orientation, all the ISS [International Space Station] and the multipurpose laboratory module [Nauka] systems are operating normally," Roscomsos officials noted.

"The crew is now busy balancing the pressure in the Nauka module.

The pair was in the process of preparing to open the paired hatches between Nauka and the rest of the station yesterday when the module's thrusters began to fire, pushing and tilting the space station until thrusters on the Russian Zvedza service module and the Russian cargo ship Progress 78 were able to counteract the misfire.
