![]() Rogozin, who regularly expresses his support for the Russian army in Ukraine on social media, has regularly made these threats. Zvezda has thirty-two attitude control engines, and Progress resupply vehicles have 24 thrusters. Thrusters located on Russia’s Zvezda Service Module and Soyuz and Progress docked spacecraft are used to perform these manoeuvres. If the ISS falls to 350km, its orbit will degrade by 90 metres a day. Due to atmospheric drag, the ISS constantly slows and must be boosted periodically to maintain its altitude. The ISS orbits Earth at an altitude ranging from 370 to 460 kilometres (230 to 286 miles) and at a speed of 28,000km/h (17,500mph). “The Russian segment ensures that the station’s orbit is corrected, on average 11 times a year, including to avoid space debris”, said Rogozin, a close Putin ally and former deputy prime minister. "We knew we had a limited amount of time," Scoville said.Russian invasion: Situation report day 366Īccording to Dmitry Rogozin, Roscosmos head, Western sanctions on Russia since President Vladimir Putin annexed Crimea in 2014 and invaded Ukraine in 2022 could disrupt the operation of Russian spacecraft servicing the ISS.Īs a result, thrusters on Russia’s Zvezda Service Module and visiting spacecraft - which help correct the ISS’ orbit - “could be affected,” causing the 500-tonne structure to “fall into the sea or onto land,” Rogozin wrote on Telegram. NASA defines such an emergency as "an anomalous state" that would result in the loss of the entire space station if it were to continue. That said, Zebulon Scoville, who was in charge of NASA mission control that day, told the Times that it was the first time he'd had to declare a "spacecraft emergency" in his seven years as a flight director. They didn't even feel the station move or shake. The crew was never in danger during that incident, according to NASA. Nauka's thrusters wound up spinning the ISS around 540 degrees and flipping it upside down before flight controllers regained control an hour later. A tug of war ensued between the errant module and the four gyroscopes that typically keep the ISS steady. Shortly after it docked to the station, Nauka began unexpectedly firing its thrusters, trying to pull itself away from the football-field-sized station. Roscosmos launched a new module, called Nauka, to the ISS in July. This is the second time this year that a Russian spacecraft has pushed the ISS out of position. Neither agency has revealed how much the space station moved, or for how long.Ī screenshot from NASA's livestream shows the Nauka module approaching its port on the International Space Station, July 29, 2021. Russia's space agency, Roscosmos, later said in a statement that the ISS orientation was "temporarily changed" but "swiftly recovered," and that nobody on board was in danger. ![]() The precise cause is not yet clear, but NASA mission control in Houston told its astronauts that the station had lost control of its orientation and instructed them to follow emergency procedures. That moved the station out of its normal orientation, The New York Times reported. It's the second time Russian hardware has caused such an incident since July.Ĭosmonaut Oleg Novitsky was conducting engine tests on the Soyuz spaceship, which is docked to the ISS, on Friday morning when its thrusters fired too aggressively.
