So how much does a Commercial Astronaut seat cost?

With the close of the Space Shuttle program we were buying seats from Russia's ROSCOSMOS at $90M per seat. As of October 2020 that cost included training, preparation for launch, flight operations, landing and crew recovery. In 2019 The Office of Inspector General projected the costs per-seat of U.S. commercial providers Boeing and SpaceX at $90M and $55M respectively. Boeing contested the report. Jeff Foust of SPACENEWS on November 19,2019 wrote that Boeing Starliner seats would around $70M.

In respect to Lockheed Martin Orion's crew modules (reuseable) NASA as of October 21, 2022 purchased three for $1.99B. The European Service Module is expendable so a new one is required for each Orion flight at around $271M U.S. dollars for each
