Space Manufacturing Could Yield Next Realm of Innovations

For decades, space has captured imaginations, prompting many to wonder what's possible. For industry, the fixation on space has resulted in numerous innovations, many of which have become a part of most people’s daily lives. However, the reality is, when analyzing space based innovations, industry has barely scratched the surface. The potential of manufacturing within space could result in truly meaning solutions to the many challenges facing earth today.

This is where Axiom Space, a privately funded space station manufacturer and orbital services provider, is hoping to make a significant difference. Axiom is currently building the world’s first commercial space station to serve as a home to human-tended microgravity research, product development and in-space manufacturing, as well as critical space-environment materials testing.

Axiom sees great opportunity to raise awareness across the manufacturing and industrial landscape that microgravity is a unique environment that can be leveraged today to build great products that cannot be made on Earth, explains Maender. “In a world where competition is fierce, and margins are tight, strategic investments into in-space manufacturing can pay big dividends. This goes for first-movers creating innovative products for existing markets and, importantly, developing new markets in a growing low Earth orbit economy,” he says. “Every new application uncovered in microgravity paves the way to greater awareness of that opportunity and acts as a lever driving diversification and cost-reduction in the launch services that support in increase in on-orbit activity.”

According to Maender, a litany of physical processes often taken for granted within Earth’s gravity do not occur in the state of permanent free-fall experienced on orbit. “When free of gravity-driven, earthly constraints, like sedimentation, buoyancy, convection, and hydrostatic pressure, we can manipulate materials and biology in new ways leading to manufacturing techniques yielding innovative new products. For example, containerless processing is possible in microgravity, creating an ultrapure environment for manufacturing or study of new materials,” he says. “Crystallization fundamentally changes in microgravity, opening opportunity to create materials with optimized physical properties. All of this combines to offer opportunities for breakthrough product development.”

Work on the ISS has already demonstrated the microgravity environment is ideal for manufacturing superior fiber optics, bio-printing of living tissues, manufacture of synthetic retinal implants and growth of ultrapure protein crystals supporting drug discovery. “These early products, along with translational research performed on the ISS, are proof that development of new metal alloys, ceramics, semi-conductors, and stem cell therapies are all possible new products that can be made in space and brought back to Earth, contributing to progress in a wide variety of areas,” says Maender.

It’s hard to overstate the potential microgravity has for a variety of users across many industries, most of which otherwise have no obvious connection to space, adds Maender. “Developing manufacturing tools and processes for space often require miniaturization, ruggedization, automation and remote operation of components and processes that will have direct tieback to innovation, modernization and cost-savings in terrestrial manufacturing,” he says. “The proof-of-concept work done in space often yields new discoveries directly applicable to improving manufacturing capability on earth. Space-based applications within manufacturing companies inevitably attract top new talent to traditional industrial sectors. New talent often begets new innovation across sectors.”
