Russia threatens to leave International Space Station program over US sanctions: reports
Russia's space chief is threatening to leave the International Space Station (ISS) program in 2025 unless the United States lifts sanctions against the Russian space sector.
"If the sanctions … remain and are not lifted in the near future, the issue of Russia's withdrawal from the ISS will be the responsibility of the American partners," Roscosmos Director General Dmitry Rogozin said during a Russian parliament hearing on Monday (June 7), according to NBC News.
"Either we work together, in which case the sanctions are lifted immediately, or we will not work together and we will deploy our own station," Rogozin added. Russia is about to launch a new docking module to the ISS this summer that could serve as the hub of an independent complex.
Rogozin also claimed that Russia cannot launch some satellites because the U.S. sanctions forbid his country from importing some microchips required for the Russian program, Reuters reported. (There is also a global shortage of microchips associated with manufacturing shutdowns amid the coronavirus pandemic.)
"We have more than enough rockets but nothing to launch them with," Rogozin said, according to Reuters. "We have spacecraft that are nearly assembled, but they lack one specific microchip set that we have no way of purchasing because of the sanctions."
