WASHINGTON — NASA has quietly signed a contract with Boeing for up to five additional Soyuz seats to provide for both additional U.S. crewmembers on the International Space Station and margin for commercial crew delays.

NASA made the deal in a modification to the Vehicle Sustaining Engineering Contract the agency has with Boeing for ISS operations. Other than the formal contract modification notification, posted Feb. 21, NASA did not announce the agreement beyond a statement published without fanfare on the agency's website.

The agreement covers two Soyuz seats on flights in the fall of 2017 and spring of 2018, with the option for three seats on Soyuz flights in 2019. The total value of the contract modification, including the optional seats, is $373.5 million, or an average of $74.7 million per seat. NASA's most recent contract with the Russian state space corporation Roscosmos for six Soyuz seats on 2018 missions has an average per-seat price of $81.7 million.

NASA has not disclosed who will fly to the station on those two near-term Soyuz seats. "Crew assignments are going through the standard process that all [ISS] Expedition assignments follow," NASA spokesman Dan Huot said Feb. 27. "Once that process has been completed, we'll announce the assignments."

The options for three seats in 2019 provide a cushion for NASA to ensure access to the ISS should commercial crew vehicles under development by Boeing and SpaceX suffer delays. "Although both commercial crew vehicles are on track right now to start flying in 2019, it seemed to us it might make sense to NASA to have some insurance just in case," John Elbon, vice president and general manager of space exploration at Boeing, said in a Jan. 17 interview.

Since the report, executives with both Boeing and SpaceX have argued that their vehicles remain on schedule for test flights planned for late this year through the middle of 2018. SpaceX Chief Executive Elon Musk reiterated plans to fly NASA astronauts in 2018 during a Feb. 27 conference call with reporters to discuss his company's plan to send two people on a circumlunar mission in late 2018, a mission he said would fly after SpaceX's first crewed missions to the ISS.

"It was good to assure accessibility to ISS and take some schedule pressure off, as it was being perceived, on commercial crew," said James Bagian, a member of the NASA Aerospace Safety Advisory Panel, during a Feb. 23 meeting of the panel at the Kennedy Space Center, alluding to the Boeing deal. "While we want commercial crew to proceed with all due haste, we don't want schedule to have unnecessary pressure that could compromise safety."
