latterly last workweek , a routine thruster test of a Soyuz ballistic capsule continued for longer than wait , causing the ISS to careen by nearly 60 degrees . It ’s yet another troubling sign that all is not well in the Russian segment of the orbital outstation .
The incident happened on Friday , September 15 , as Russian flight controllers were run a pusher fire trial run of the Soyuz MS-18 spacecraft , which arrived at the ISS in April . The trial was being done in preparation for the departure of astronaut Oleg Novitsky and aRussian film crewconsisting of actress Yulia Peresild and film director Klim Shipenko .
When the mental testing windowpane ended , however , the thruster kept on firing , which was n’t presuppose to chance . With the spacecraft still bond to the ISS , the “ station ’s preference was impacted , ” agree toRoscosmos . ” The Russian quad means said attitude control “ was swiftly recovered due to the actions of the ISS Russian Segment Chief Operating Control Group specialists,”and that the “ place and the bunch are in no risk . ” The departure of the Soyuz spacecraft went as plan a few sidereal day after , with the gang of three landingsuccessfullyon October 17 .

The loss of orientation course began at 5:13 a.m. EDT , and it took trajectory controllers 30 minutes to return the orbital outpost to a “ static form , ” according toNASA . The incident was serious enough for NASA to declare an emergency , in which its astronauts were told to reference procedures in the crowd ’s “ word of advice book , ” as the New York Timesreports . Russian intelligence way InterfaxcitedVladimir Solovyov , escape film director of the Russian segment , as say the ISS budge by 57 degrees .
A similar incident come about in July , when the newly docked Nauka module unexpectedlyfiredits thrusters , make the ISS toshiftby 540 degree . It was one of the most serious sequence to have occurred in the infinite station ’s 21 - year history . A series ofair leaksand sign ofdeteriorationin the Russian segment suggest Russia is not doing its part to keep the distance post and that the aging ISS is becoming progressively unsafe .
NASA and Roscosmos are presently play together to figure out what happened on Friday . The New York Times cite NASA trajectory director Timothy Creamer as aver the thrusters may have “ stop fire because they get through their prop[ellant ] limit . ” In an email , I necessitate Jonathan McDowell , a investigator at Harvard - Smithsonian Center for Astrophysics , what Creamer think by that .
“ The ‘ property limit ’ was , I am led to understand , a software limit set for that burn , ” rather than a limit have to do with dwindle down fuel reserves , McDowell reply . “ So the total amount of propellent used did n’t put the ship in risk of not being capable to get family or anything like that … [so ] I do n’t call up the office was as concerning as the Nauka issue . ”
That state , McDowell said incident like this should not happen . This in vogue sequence bring “ to the belief that the Russian section of the ISS is being run in a rather cavalier fashion with deficient quality control and safety checks on the thruster software and hardware , ” he tell .
At the same prison term , Russia is not being as transparent as it should be , McDowell tot . “ We know the tan lasted somewhere between 11 and 30 minute but not exactly how long , and we do n’t know how long it was meant to be in the first seat , so that makes it hard to evaluate , ” he say .
Roscosmos did not instantly respond to Gizmodo ’s petition for more information , such as a likely cause for the incident .
Russia ’s donation to this historical space project may be coming to an destruction . The country hasthreatenedto leave the ISS by 2025 andbuildits own blank space station by 2030 . The current U.S. programme is to abide the orbital frontier settlement through at least 2030 .
