Flight controllers at NASA and Roscosmos averted a disaster on Thursday after a large Russian module docked with the International Space Station and began to “inadvertently” fire its thrusters.
The Russian “Nauka” module linked to the space station at 8:30 am CT (13:30 UTC), local time in Houston, where NASA’s Mission Control is based. After that, Russian cosmonauts aboard the station began preparing to open the hatches leading to Nauka, but at 11:34 am Houston time, Nauka unexpectedly started to fire its movement thrusters.
Within minutes, the space station began to lose attitude control. This was a problem for several reasons. First of all, the station requires a certain attitude to maintain signal with geostationary satellites and talk to Mission Control on the ground. Also, solar arrays are positioned to collect power based upon this predetermined attitude.
