Each KEU-MM Experiment Unit contains 3 Culture Bags (CB) capable of growing small animals (i.e. worms). The three CBs are totally independent and are filled with the live animals and their food into a liquid solution.

The Culture Bags features a flexible, transparent and semipermeable membrane allowing either gas exchange between the CB and the external environment and also CB to change its volume in case of freezing. Moreover, the transparency of the semipermeable membrane allows the visual observation of the culture without disassembling the unit. After re-entry on Earth both the animals and the process fluids can be retrieved for analysis.

The KEU-MM Experiment Unit is planned to be used to determine the molecular causes of muscle abnormalities during spaceflight, and target these to establish effective countermeasures and future therapeutic developments. The biological sample is composed of liquid cultures containing larvae and liquid bacterial feed to allow population growth.

Each KEU-MM Experiment Unit (EU) is made of plastic bags with excellent mechanical and chemical resistance properties, biologically inert. Cross contamination among the CBs is avoided due to proper sealing of the CBs. The EU itself doesn’t provide any Level of Containment (LoC).

 The unit is fully passive; no activations or fluids movement are foreseen.
