The latest endeavor, projectFINIX, is scheduled to launch on the REXUS 34 sounding rocket in Q1 2025. Building on these previously conducted missions, FINIXseeks to advance ferrofluid-based solutions with future applications in space systems. These novel developments hold the potential toreplace conventional mechanical components in space applications, which are subject to wear and tear and hence represent a limitingfactor for space missions. This paper details the experiments planned for the technology demonstrator mission FINIX, focusing onthe development of an electrical switch and a pump, and their connection to earlier developments. The design, testing, and validationprocesses of these ferrofluid-based experiments will be discussed, highlighting the scientific objectives and innovations of the project.
