RISE OF SPACE BIOMANUFACTURING
Increasing access to space is bringing increasing public and private efforts to leverage the unique environment of microgravity to enhance biological processes and production methods. Promising capabilities in pharmaceuticals, materials science, and regenerative medicine are being unlocked. Increased access to space will expand activity in this area and bring benefits to human health on Earth.
Microgravity conditions aboard space platforms are a setting where biological organisms and systems can behave differently as they aren’t contending with gravitational pull. For example, protein crystallization happens more uniformly, and delicate tissue can grow without being pulled out of shape. As the transition from space-based research being limited to government space stations to sustained commercial operations in low Earth orbit (LEO) occurs, the resulting innovations are poised to address critical challenges on Earth. These include producing advanced biomaterials, developing more effective pharmaceuticals, and creating resilient supply chains for essential medical products.

Varda Space Industries: Drug Formulation in Microgravity
Varda Space was founded by Will Bruey and Delian Asparouhov in 2021 to manufacture in microgravity and bring those products back to Earth. Bruey had been an engineer at SpaceX and Asparouhov is a partner at Founders Fund. Varda has raised $141 million over five rounds. They have revenue in the form of government contracts for testing and have already successfully completed two space missions.
Varda developed and built a small, 300 kg, spacecraft that can be launched to space, complete autonomous manufacturing, and return to Earth with products intact. The first mission was groundbreaking in several ways:
The W-1 spacecraft launched to space on a SpaceX Falcon 9 rocket in June 2023 marking the first commercial in-space pharmaceutical manufacturing effort.
While in space, the antiviral drug ritonavir was made into a more soluble form, called form III crystals. Currently this medication needs to be formulated with additives to be absorbed in the stomach because it has a tendency to form sediment. Without gravity, this sediment doesn’t form and so the more soluble form can be made with stability.
In February 2024, W-1 had a successful re-entry and landing in Utah, making it the first commercial spacecraft to land on US soil.
Upon return, the Ritonovir was found to have retained its soluble form III crystals.
Varda's accomplishment marks a significant milestone in pharmaceutical manufacturing, suggesting that the microgravity environment can be harnessed to produce drug formulations with enhanced properties that are difficult or impossible to achieve on Earth.
Building on that success, Varda just completed their second mission:
Varda’s W-2 spacecraft was launched by SpaceX in January 2025 and successfully made the first commercial landing in Australia.
This mission included a spectrometer to take measurements for hypersonic testing during re-entry under a $48 million contract with the Air Force Research Lab. A heat shield thermal protection system designed in collaboration with NASA was used. Pharmaceutical equipment was also included and for testing.
Varda shows promise with early technological success in space missions and two product lines: drug formulation capability not available on Earth and re-entry capsules capable of withstanding hypersonic speeds allowing for testing.
LambdaVision: Space-Based Manufacturing of Artificial Retinas
LambdaVision was founded in 2009 by Dr. Robert Birge and Dr. Nicole Wagner from the University of Connecticut. They are at the forefront of developing an artificial retina to restore vision in patients with retinal diseases like retinitis pigmentosa and macular degeneration. The company has used the microgravity environment via the International Space Station (ISS) to enable to necessary fine tissue building. The company received a $5 million dollar grant from NASA to support its work and, in May 2024, completed a seed round led by Aurelia Foundry Fund, as well as receiving investment from Connecticut Innovations. They’ve received an estimated $17 million in total grants and investments.
The production of LambdaVision's artificial retina involves a meticulous layer-by-layer assembly of approximately 200 ultra-thin layers of the light-sensitive protein bacteriorhodopsin. On Earth, gravitational forces can cause sedimentation and convection, leading to inconsistencies in these layers; microgravity conditions minimize these effects, resulting in more uniform and stable layer formation, which is crucial for the implant's performance.
LambdaVision has completed multiple missions to the ISS to refine and validate its manufacturing process:
In December 2018, the first experiment demonstrated the feasibility of layer-by-layer assembly in microgravity.
In December 2021, additional research successfully produced four films, one of which reached the target of 200 layers, validating the layer-by-layer manufacturing process in microgravity.
In April 2022, improved hardware automation and in-orbit process controls, leading to the development of 10 test retinas that were returned to Earth for analysis. Goals included ensuring that the delicate layering process remained intact during and after the microgravity exposure, verifying that the bacteriorhodopsin protein retained its light-sensitive properties essential for mimicking photoreceptor functions, and assessing the consistency and evenness of the protein layers, which is crucial for optimal retinal performance.
In January 2024, evaluated the transport of bacteriorhodopsin in powdered form to the ISS to help the manufacturing process for scalability. Previously, the protein was sent in solution which could degrade over time, especially under varying environmental conditions, and required special handling to avoid psillage and contamination. The shift to a powdered form aimed to address those issues because powdered proteins are less susceptible to degradation and more robust in storage, and powder reduces the volume and weight of the payload. During the mission, the powdered bacteriorhodopsin was successfully reconstituted into solution aboard the ISS. It was tested to ensure the reconstituted protein was free from contaminants and retained the critical light-absorbing capabilities. This was considered a crucial step toward scalable production of artificial retinas in space
With a building track record and solid funding, LambdaVision is poised to transition from research to clinical applications, offering hope to millions affected by retinal disease.
