2025 Year in Review

2025 was a landmark year for Axiom Space, as we solidified our leadership in commercial human spaceflight and set bold new milestones to redefine humanity’s presence in low-Earth orbit (LEO) and beyond. From historic astronaut missions to cutting-edge infrastructure development, here’s a snapshot of how Axiom Space is defining the future of space exploration — with numbers, achievements, and highlights that showcase our undeniable momentum to Transcend Earth.

Axiom Mission 4 (Ax-4): Building the Human Experience

• 4th successful commercial human spaceflight mission onboard the International Space Station.
• 4 nations represented: USA, India, Poland, and Hungary — with India, Poland, and Hungary sending their first-ever government astronauts to the space station.
• More than an 18-day mission on station led by Commander Peggy Whitson.
• Conducted 60+ scientific experiments representing 31 nations — the highest number ever on an Axiom Space mission.
• Ax-4 science included groundbreaking diabetes research demonstrating real-time glucose monitoring and insulin delivery in microgravity, as well as cancer research continued from previous Axiom Space missions that tested the therapeutic cancer drug Rebecsinib, which entered clinical trials this year.

Axiom Station: Building a Foundation for the Future

• We revised the assembly sequence, targeting a two-module, free-flying station no earlier than 2028 with a fully independent, four-module commercial station as the successor to the International Space Station.
• This will ensure an uninterrupted U.S. human presence in LEO post-International Space Station retirement – a vital step for commercial, scientific, and national space objectives.
• Completed the first module's final welds, with testing of the pressure vessel underway.
• Proprietary Axiom Docking Adapter (AxDA) reached 80% design completion to enable seamless connection with commercial visiting vehicles.
• Completed the first software integrated, propulsion thruster hot-fire demonstration.
• Axiom Station second module completed Preliminary Design Review (PDR) in mid-December

AxEMU: Building to Advance Lunar Exploration

• Completed the first AxEMU dual-suit run in NASA’s Neutral Buoyancy Laboratory (NBL).
• Executing final integration tests in NBL.
• Successfully completed the first uncrewed thermal vacuum test of the pressure garment assembly.
• Accumulated over 800 hours of crewed pressurized time in the AxEMU.
• Delivered over 1,200 critical design review products related to NASA’s Artemis III and International Space Station missions.
• Initiated production of qualification and flight hardware for the Artemis III mission.
• Partnered with Oakley to develop a next-generation visor system for the Axiom Extravehicular Mobility Unit (AxEMU).
• Collaborated with Nokia to integrate advanced 4G/LTE communication capabilities into the spacesuit.

Orbital Data Centers: Building the Cloud in Space

• Launched the first orbital data center prototype, AxDCU-1, to the International Space Station, demonstrating initial Orbital Data Center (ODC) capabilities.
• Received up to $5.5 million in funding from the Texas Space Commission for ODC development.
• Planning to deploy two, free-flying data nodes in LEO in January 2026, with further nodes increasing compute capacity in coming years — an essential step toward establishing the first orbital cloud computing network for government, commercial, and civil customers worldwide.

International Collaboration: Building Global Impact

• Signed a number of new international agreements with governments, businesses, and academic institutions across multiple continents in 2025 alone.
• Established the Axiom Space University Global Alliance – a global initiative designed to elevate and identify scientific research gaps and opportunities that can shape national and international research priorities. These relationships expand microgravity research opportunities, tech development, and commercial innovation in space — crucial for advancing knowledge, sharing resources, and decreasing risk.
• Welcomed a diverse array of visitors including government officials, space leaders, commercial innovators, and even NBA star Victor Wembanyama of the San Antonio Spurs, demonstrating the growing excitement around commercial space.
