Following the docking of the Multipurpose Laboratory Module (MLM), named Nauka, to the International Space Station at 9:29 am EDT, Russian cosmonauts aboard the space station conducted leak checks between Nauka and the service module. At 12:45 pm, the flight control team noticed the unplanned firing of MLM thrusters that caused the station to move out of orientation. Ground teams have regained attitude control and the motion of the space station is stable.
The crew was never and is not in any danger, and flight controllers in Mission Control Houston are monitoring the status of the space station. Teams are also monitoring the impact to tomorrow’s launch of the Boeing Starliner spacecraft. Updates on the space station will be provided on NASA.gov and the agency’s social media pages.
As a result, the upcoming Boeing Starliner launch that was set for tomorrow has been pushed back while the ISS team conducts further checks on Nauka:

NASA and Boeing have decided to stand down from Friday’s launch attempt of the agency’s Orbital Flight Test-2 mission. Currently, launch teams are assessing the next available opportunity. The move allows the International Space Station team time to continue working checkouts of the newly arrived Roscosmos’ Nauka module and to ensure the station will be ready for Starliner’s arrival.
No word yet on when they will launch Starliner.
