WASHINGTON — Axiom Space has signed a contract with SpaceX for three additional Crew Dragon missions, enough to meet its projections for private astronaut missions to the International Space Station through at least 2023.

Axiom, which already has a deal with SpaceX for the Ax-1 mission to the ISS launching in early 2022, said June 2 the new contract covers the projected Ax-2, 3 and 4 missions to the station. All will use Crew Dragon spacecraft launched on Falcon 9 rockets.

The companies did not disclose the terms of the agreement, including whether Axiom Space negotiated a lower price through a block buy. Axiom spokesman Beau Holder told SpaceNews that the biggest benefit of the agreement was ensuring access to the Crew Dragon for its future missions.

“It secures a vehicle that is flight-proven and ready to support the crewed launch cadence Axiom is planning: approximately every six or seven months leading up to near the launch of the first Axiom module to ISS,” he said. “Expanding this partnership between two key industry leaders cements the commercialization of low Earth orbit.”

Axiom finalized an agreement with NASA for the Ax-1 mission May 10. That Crew Dragon mission, scheduled for launch in early 2022, will be commanded by former NASA astronaut Michael López-Alegría with three customers: Larry Connor, Mark Pathy and Eytan Stibbe.

Axiom announced May 25 that another former NASA astronaut, Peggy Whitson, will command the Ax-2 mission. She will fly with John Shoffner, a private astronaut, and two additional customers to be announced. Axiom did not disclose at the time what vehicle the two would use for that mission, but Whitson and Shoffner had already been assigned as backups for the Ax-1 mission.

Michael Suffredini, Axiom’s president and chief executive, said last month that the company had missions lined up through Ax-4, but did not disclose details about who would fly on those missions or when they would launch. “We still have to work with NASA to figure out exactly when those flights can come to the ISS,” he said at a NASA briefing about Axiom’s agreement for the Ax-1 mission.

NASA’s low Earth orbit commercialization strategy, announced two years ago, allows two private astronaut missions a year to the ISS. That is based on the amount of traffic from other visiting vehicles to the station, and NASA officials said last month they don’t envision increasing that in the near future.

The new contract would allow Axiom to fly missions to the station through 2023, if it is able to secure agreements for the other private astronaut mission opportunities in 2022 and 2023. “We’re prepared to fly on a cadence of about twice a year, but like everyone, we have to compete for the opportunity,” Suffredini said at the briefing.

SpaceX, in a separate statement, sounded optimistic about Axiom’s chances of securing those additional ISS private astronaut missions, noting that the agreement covers “three additional private crew missions aboard Dragon to and from the Station through 2023.”

In addition to Axiom, SpaceX is flying the Inspiration4 mission on a Crew Dragon launching this fall. That mission, commanded by billionaire Jared Isaacman, will not dock with the ISS but instead fly in a higher orbit for three days before returning.

Space Adventures announced February 2020 an agreement with SpaceX for a similar Crew Dragon mission, one that would spend several days in orbit but not visit the ISS. At the time Space Adventures said the mission would take place between late 2021 and the middle of 2022, but the company has not updated on the schedule for the mission or announced who will fly on it.

“We are beyond excited to build upon our partnership with Axiom to help make human spaceflight more accessible for more people,” Gwynne Shotwell, president of SpaceX, said in a statement. “A new era in human spaceflight is here.”
