Between 2006 and 2024, NASA shelled out more than $3.6 billion to Roscosmos for ferrying astronauts to the International Space Station aboard Soyuz spacecraft. Breaking it down, that’s 68 seats at roughly $79.7 million each-a stark reminder of how costly the gap between the Space Shuttle’s retirement and America’s next-generation crew vehicles turned out to be.
After the Space Shuttle was retired in 2011, Soyuz remained NASA’s sole ticket to the ISS for several years. The Commercial Crew Program, aimed at ending reliance on Russia, took longer than expected to get off the ground. SpaceX’s Crew Dragon only launched with a crew in 2020, years after it was initially planned. Meanwhile, between 2017 and 2024, NASA bought an additional 12 Soyuz seats from Roscosmos for close to $1 billion.
This extended hiatus between the Shuttle era and stable Commercial Crew flights made Russia’s Soyuz vehicles an indispensable fallback for NASA’s ISS missions. Back in 2014, NASA handed out contracts worth $2.6 billion to SpaceX and $4.2 billion to Boeing to develop new crew capsules. But so far, only SpaceX has established regular flights-Boeing’s Starliner is still struggling to enter consistent service, with reliable operations not expected until 2026.
NASA’s Soyuz seat purchases and pricing breakdown
- 68 Soyuz seats purchased from 2006 to 2024
- Average cost per seat: approximately $79.7 million
- Additional 12 seats bought between 2017 and 2024 for about $1 billion
NASA-Roscosmos seat swap agreement since 2022
Since July 2022, NASA and Roscosmos have operated a seat swap system: Russian cosmonauts ride aboard Crew Dragon, while American astronauts continue flying Soyuz. This arrangement isn’t about saving money-it’s insurance. If one spacecraft type hits a snag, crews from both countries can still reach the ISS, ensuring that both the Russian and American segments remain staffed by trained personnel.
Future of Soyuz flights amid ISS operations through 2030
With plans to keep the ISS running at least through 2030, Soyuz won’t just be a backup option for NASA. Instead, it’s set to remain an active part of how the station operates, even as Crew Dragon builds up its flight cadence. For now, NASA’s partnership with Roscosmos remains vital, underscoring the ongoing interdependence in space despite geopolitical tensions.
