California-based Varda Space Industries achieved its first in-space manufacturing milestone with the successful return of the W-1 mission's capsule on February 21st at 01:40 p.m. PST (04:40 p.m. EST). The capsule, an orbital platform produced by Varda, landed at the Utah Test and Training Range after nearly eight months in orbit.
The payload featured microgravity-cultivated antiviral drugs in LEO, aligning Varda with companies recovering intact spacecraft from orbit like SpaceX and Boeing.
Varda: Innovating Space Manufacturing for LEO Access
Varda Space Industries, founded in 2020, pioneers space manufacturing to boost Low Earth Orbit (LEO) accessibility, focusing on pharmaceuticals and product development.
Utilizing microgravity, Varda envisions manufacturing drugs and goods in space, using proprietary reentry capsules for transportation- a departure from traditional microgravity research on the International Space Station (ISS). Unmanned capsules act as mini-factories and return vehicles in Varda's innovative approach.
The W-1 test mission, launched in June 2023 as part of SpaceX's Transporter-8 rideshare mission, marked Varda's inaugural opportunity to demonstrate its capabilities. The 3-foot-wide conical capsule, integrated into a Rocket Lab Photon spacecraft, spent eight months in orbit, emphasizing the efficiency and cost-effectiveness of Varda's approach.
With the increasing accessibility facilitated by reusable rockets and rideshare programs, numerous industries, including biomedical and advanced materials research, are exploring opportunities in space.
Varda explores microgravity's impact on material processing, improving pharmaceutical quality and extending applications to high-hypersonic flight testing and technology development.
CEO Will Bruey emphasizes that removing gravity from the manufacturing process in space unlocks new possibilities, likening it to adjusting a parameter like temperature in an oven to create novel recipes and food.
Launched atop a SpaceX Falcon 9 rocket in June 2023, the W-1 capsule spent eight months integrated with a Rocket Lab Photon spacecraft. This integrated system provided power, propulsion, and navigation services, showcasing the potential of Varda's innovative approach to space manufacturing and research.

W-1 Capsule: Orbital Drug Processing Triumph
The W-1 capsule transported crucial materials to cultivate Ritonavir crystals, an antiviral medication used for treating HIV and hepatitis C. Varda intentionally selected pharmaceuticals as part of the payload, aiming to foster the expansion of the off-Earth manufacturing sector.
Within a week of Transporter-8's launch, Varda successfully executed the crystal-growing experiment, marking the first instance of orbital drug processing outside a government-run space station. The company expressed optimism about commercializing microgravity and establishing an industrial park in low Earth orbit (LEO).
Upon the capsule's return, Varda plans to transport it to their Los Angeles facilities for post-mission analysis, while the drug will be shipped to their commercial partner.
Despite the initial plan to retrieve the crystals within a month or two, challenges in obtaining U.S. reentry approval caused delays. However, eventual approval facilitated the successful reentry of the W-1 capsule, which survived Earth's atmosphere and landed at UTTR. Varda underscores the significance of mission data, including hypersonic speeds, shared with the Air Force and NASA under contracts.
Looking ahead, Varda is gearing up for its second launch in the summer, utilizing another Photon spacecraft. The company's commitment to advancing pharmaceutical research in space and collaborating with entities like Improved Pharma demonstrates its dedication to innovation and knowledge sharing in the realm of space manufacturing.
