The Thermolab experiment uses the Damec-developed Portable Pulmonary Function System (Portable PFS) to investigate thermo-regulatory and cardiovascular adaptations during rest and exercise in the course of long-term exposure to weightlessness. The Portable PFS basically uses data from breathing gases as indirect and/or direct measure for the sought values. The Maximum Volume Oxygen (VO2 Max) experiment is aimed at measuring oxygen uptake and cardiac output in particular, during various degrees of exercise.

The Principal Investigator is Prof. Dr. Hanns-Christian Gunga, Center for Space Medicine Berlin (ZWMB), Institute of Physiology, Charité Universitätsmedizin, Germany.
