Beyond the ISS: Axiom Space’s Path to Commercial Space Leadership

By Sunita Arnold, Aug 1, 2023

As humanity’s reliance on space-based services including communication, positioning, navigation, weather tracking, earth observation, and the Internet of Things (IoT) grows, so too does the significance of space systems. They have become a crucial part of our infrastructure, enabling us to predict weather patterns, monitor wildfires, and facilitate navigation. The space industry has experienced a surge in innovation and investment, leading to a significant decrease in the cost of satellites, components, and launches. This has opened the door for the development of new capabilities using existing space infrastructure.

Axiom’s Role in the Changing Landscape of Space Activity

The International Space Station (ISS), a remarkable product of collaboration among 14 countries, was an ambitious project that fostered global unity and led to significant scientific discoveries. Now, as the ISS nears its retirement in 2030, a new era of space activity looms. The emergence of China’s Tiangong space station highlights the shifting dynamics in space, underlining national security implications for the U.S. and the Western world.

Recognizing the need for a commercial successor to the ISS, NASA initiated a competition to select a commercial space station replacement. Axiom Space, founded by experienced leaders from the ISS Program and the only company granted permission to connect its modules to the ISS, was chosen to lead this transition. The company is now building Axiom Station, the world’s first commercial space station, to help maintain a balance in space activities and address evolving national security challenges.

Axiom Space: Pioneering Commercial Spaceflight Services

Axiom Space is carving its own path in the realm of commercial spaceflight. As a leading provider of human spaceflight services and developer of infrastructure safe for human habitation in space (human-rated space infrastructure), the company has a unique vision for the future. Axiom is pioneering the transition from ISS operations to its own commercial space station, Axiom Station.

Life Science Capabilities 

Stem Cell Research

According to Axiom, Microgravity–the condition in which people or objects appear to be weightless–provides unique advantages to study stem cells, particularly in the context of understanding the aging process as well as offering an environment that optimizes in vitro cell culture conditions for stem cell renewal and expansion. First, microgravity induces an aging phenotype in many in vivo physiological systems on an accelerated timescale, which can be modeled in stem cells to study their behavior under the same conditions. Further, microgravity provides a superior environment for cultivating stem cells in vitro. As Axiom explains, on Earth, it is difficult to maintain primary cultures of stem cells, as these cells are driven to differentiate or quickly reach senescence.

3D Bioprinting 

3D bioprinting is an innovative and emerging technology that combines principles of 3D printing with biological materials to create three-dimensional structures and functional tissues. Axiom believes microgravity may be an ideal environment for 3D bioprinting of tissue structures. On Earth, bioinks must retain a 3D structure that defies gravity, which usually requires higher-viscosity materials. The higher-viscosity bioinks, however, have a negative impact on cell biology and survival during the printing process. Microgravity conditions could, therefore, provide an environment in which lower viscosity bioinks can be utilized while maintaining 3D structure.

Medical Capabilities

Aging Research

According to Axiom, spaceflight offers aging researchers a distinct research model in which to test new ideas that may uncover meaningful discoveries. Axiom has studied the role of aging upon rodents–who display similar age-related changes to humans in space–who have spent time in orbit. Future Axiom studies are expected to produce genomic, transcriptomic, and proteomic data from various tissues. Axiom believes these results will push the boundaries of our understanding of the aging process in space and on Earth and serve as the foundation for future studies to test novel hypothesis-driven ideas and promising interventions and drugs.

Bone Osteoporosis Research

Bone is living tissue that strengthens with exercise and deteriorates with long-term inactivity and aging, Axiom therefore believes that the development of new therapies targeting pathways that promote bone formation and block bone resorption are crucial, as humans spend more time in space. Axiom’s space station will be equipped to address a broad range of bone-related research questions, with the company developing a state-of-the art rodent habitat to be used as a space vivarium that will support up to 300 mice for modeling bone diseases in space.

Medical Implants

Space exploration offers the potential to find a cure to Retinitis pigmentosa and macular degeneration; two common retinal degenerative diseases that affect 1.5 and 30 million people globally and lead to end-stage blindness. While such a protein-based retinal implant provides significant improvement compared to other leading therapies on the market, manufacturing has been a challenge. However, when manufactured in the microgravity environment of Low Earth Orbit, test implants have shown significant improvements in quality. According to Axiom, a microgravity environment confers a unique advantage for fabricating high-quality thin retinal films, via layer-by-layer deposition, which have a variety of applications beyond the artificial retina.

Other Capabilities

According to Axiom, their Ax-1 and Ax-2 mission are already taking on a growing list of research investigation and capabilities, including:

  • Stellar stem cells in collaboration with Board of Governors Regenerative Medicine Institute at Cedars-Sinai
  • Cancer in low-Earth orbit in collaboration with Sanford Stem Cell Institute at UC San Diego
  • mRNA response and stability in Space in collaboration with King Faisal Specialist Hospital & Research Center, Saudi Space Commission (SSC)   
  • Modeling tumor organoids in low-Earth orbit, in collaboration with UC San Diego and The Sanford Consortium for Regenerative Medicine. 
  • Cloud seeding in microgravity in collaboration with King Fahd University of Petroleum & Minerals (KFUPM), Saudi Space Commission, and Nanoracks

Axiom Station: A Step Towards Future Innovations

Axiom Space aims to create a platform that paves the way for breakthroughs in research, in-space manufacturing, technology, and innovation. The construction of the first module of the Axiom Station has begun in collaboration with Thales Alenia Space, Axiom’s partner and a key player in the aerospace sector.
