Commercial biotech research in microgravity got another boost by the expansion of an agreement between Exobiosphere and Voyager Technologies.
Two additional research campaigns will be carried out aboard the International Space Station (ISS).
Exobiosphere’s Orbital High-Throughput Screening in Microgravity (OHTS) platform is a mid-deck-locker-class system for automated drug screening. The OHTS is scheduled for installation aboard the ISS in April 2027.
These two new campaigns — rather than a one-off opportunity — follow in quick succession: the first launching on an ISS Program Commercial Resupply Services mission in June 2027, the second in the August–September 2027 timeframe.
Samples, test compounds and consumables
According to Voyager, the Exobiosphere OHTS is designed to be resupplied. “Samples, test compounds and consumables are exchanged between campaigns, and the science configuration is adapted to each investigation.”
This single platform in orbit can support a sequence of independent research programs, with each campaign informed by the findings of the one before it.

Thousands of experiments
“Every campaign runs thousands of experiments on standardized well plates, each one mirrored by an identical control on the ground — so every orbital result arrives with the Earth comparison that makes it interpretable. Across successive campaigns, that produces something space biology has not had before: a growing, directly comparable body of actionable data,” a Voyager statement explains.
Under the agreements, Voyager Europe provides program management, ISS mission integration and mission provisioning for each campaign, including safety and verification to NASA Safety Review standards, manifesting on ISS Program Commercial Resupply Services vehicles, coordination of on-orbit operations and the return of samples to Earth.
Work is performed with Voyager’s affiliate Nanoracks LLC d/b/a Voyager Space Solutions, which handles final payload processing, NASA-required pre-flight preparations and console operations from its Houston-area facility.
