On February 21, a meter-wide space capsule landed in the Utah desert after eight months in orbit. The cargo is a batch of ritonavir, an antiviral drug used to treat HIV and COVID-19.
Carried out by a California startup Varda Space Industries, the mission aims to showcase the potential of automated drug manufacturing in space, potentially opening doors for more efficient ways to develop medications.
Varda’s W-1 mission was launched on a SpaceX Falcon 9 rocket in June 2023. The capsule itself weighs about 90 kg, capable of producing nearly 100 kg of product during several months in orbit.
However, the initial mission produced only a small amount of ritonavir during a 27-hour test run.
In-flight analysis indicates that the manufacturing process was executed as planned, and while final results are pending, Varda is gearing up for its second mission carrying its first commercial payload.

But why the focus on space?
Experiments in microgravity have shown that it’s possible to produce pharmaceuticals more efficiently in space compared to on Earth. The unique conditions in space enable the growth of crystals used in medications to be more perfect and uniform.
Pharmaceutical companies are leveraging insights from space experiments to enhance manufacturing processes on Earth. Crystals grown in space demonstrate exceptional properties that could lead to more effective drugs than those produced on Earth.
Varda and other companies are exploring the potential of harnessing microgravity to develop new drugs, ushering in a new era of pharmaceutical innovation.
Economics present a challenge in producing materials in space for Earth use, but advancements in reusable spacecraft and versatile space labs are driving costs down and opening up new possibilities for scientific discovery.
Experts like Dr. Ann Wilson and Dr. Katie King are at the forefront of research in crystal growth and pharmaceutical development in microgravity, shaping the future of space-based manufacturing.
