Abstract

Sounding rockets are valuable experimental platforms for investigation of gravity-related physiological mechanism in living organisms. The obtained microgravity quality is excellent and the time scale of 6 -14 min microgravity is sufficient to examine various physiological parameters. Freefall or space experiments are the only possibility to avoid gravity and to obtain mechano-sensitive structures in a non-influenced state. Our group uses sounding rocket experiments to investigate the gravity-oriented movement behavior of the unicellular flagellate Euglena gracilis. In intensive laboratory experiments and during the course of eight TEXUS and two MAXUS campaigns it was found that the movement of the cells with respect to the gravity vector is controlled by an active physiological mechanism. The. experiments indicated possible elements of a signal transduction chain, which is presently under investigation by means of molecular biological methods.
