Starlab Space LLC and the Center for Space and Aviation Switzerland and Liechtenstein (CSA) have launched an international Call for Proposals for microgravity research aboard the International Space Station (ISS), with up to four selected teams receiving funded access to space.

According to a press release, one award is open to a principal investigator based anywhere in the world, while three awards are reserved for teams with a principal investigator located in the Canton of Zurich. All awards are funded by Starlab, with the Zurich-based awards jointly funded by Starlab, CSA, and the Canton of Zurich.

Selected investigations will use BioServe Space Technologies' Group Activation Pack hardware, which contains eight Fluid Processing Apparatuses. Awardees will receive support for payload integration, launch, on-orbit operations, crew time, and return of experimental samples.

Eligible research areas include microorganisms, mammalian cells and tissues, viruses and bacteria, protein crystal growth, fluid dynamics and mixing, biomaterials, and plant research.

The proposal process opened Sept. 11, with Step-1 questions due Sept. 25 and Step-1 proposals due Oct. 9. Award notifications are anticipated in December 2026, with flight opportunities targeted for 2028.

Starlab Space is a joint venture among Voyager Technologies (NYSE: VOYG), Airbus, Mitsubishi Corporation, MDA Space, Palantir Technologies, and Space Applications Services.
