Microgravity Research for Versatile Investigations (MaRVIn) is an experiment processing system for operating scientific and commercial investigations in microgravity. Interchangeable experiment modules offer heating, cooling, internal fluids and chemicals management, power, data recording, telemetry and video utilities. Sample processing from zero to over 1000°C is supported.

M.a.R.V.I.n. consists of a control system that allows easily swappable test trays to be used in a variety of circumstances.  Typically the trays are about the size of two stacked reams of copy paper (215 x 245 x 75mm).

Possible work areas include the Microgravity Science Glovebox (MSG), Maintenance Work Area (MWA), EXPRESS System, or Life Science Glovebox (LSG).

The combined system provides heating, cooling, internal fluids/chemicals
