Life Science Innovations Thrive under Zero-Gravity Conditions
In the ever-evolving world of space exploration, a new chapter is being written as commercial players venture into the space station market. Among these pioneers are China's Tiangong and India's Bharatiya Antariksh Station, joining the ranks of established contenders such as Axiom Space, Airbus LOOP, Blue Origin, Sierra Space's Orbital Reef, Voyager Space, and Lockheed Martin's Starlab.
These commercial space stations are poised to be at the forefront of in-orbit science, offering a unique environment for research and manufacturing. One such opportunity lies in microgravity, which presents possibilities for flawless crystallization of semiconductor materials and the production of perfect stem cells.
Companies like the UK's Space Forge, Germany's Eva consortium, and the US' Varda Space are capitalizing on this potential by offering microgravity-as-a-service to industries looking to leverage the benefits of manufacturing in space. McKinsey & Co predicts that the space manufacturing market could reach $10 billion by 2030, underscoring the growing interest in this field.
Axiom Space, for instance, is building the world's first commercial space station, Axiom Station, with the aim of providing an accessible platform for private companies and governments to continue innovative research and development. The station is designed to enable iterative science, expand access, and reduce costs over time, building new sustainable economies in space.
One of the key areas of research on Axiom Station is the study of stem cells, which can arrange themselves in new three-dimensional structures in a microgravity environment. This has potential implications for regenerative medicine, as well as the production of organoids, miniature organs used for research purposes. Axiom Space has partnered with the Sanford Stem Cell Institute to study tumor organoids in microgravity, and is also conducting research on a new cancer drug in space.
Other research institutions, such as the Leibniz University Hannover and Otto von Guericke University Magdeburg, are collaborating on 3D printing and welding technologies in microgravity. This cost-effective development and production for microgravity research and manufacturing is made possible through partnerships with organizations like the European Space Agency (ESA), which partners with various European Cooperation States and industry firms under programs funded partly by the EU.
The benefits of microgravity extend beyond scientific research. Space Forge, for example, aims to become the primary commercial platform for in-space semiconductor production, offering rapid turnaround from manufacturing to delivery on Earth. The company's goal is to provide scales suitable for integration into telecoms networks, electric vehicles, data centres, and renewable energy systems.
Recent experiments have demonstrated the potential of microgravity for producing stem cells more efficiently or at a higher yield. Dr. Arun Sharma's team sent experiments to the ISS via a SpaceX resupply mission to examine if microgravity aids the production of heart and brain organoids. Meanwhile, Los Angeles' Cedars-Sinai Medical Centre successfully demonstrated the creation of new induced pluripotent stem cells in space.
The potential for innovation in microgravity research is immense, as emphasized by Dr. Lucie Low, Chief Scientist at Axiom Space. As these commercial space stations continue to push the boundaries of what is possible, we can expect to see exciting developments in the field of space-based research and manufacturing.
