Science

The project team is compiled interdisciplinary and there are various subjects. For each subject there is assigned a student with specific skill. Each one of these subjects present its own requirements and challenges which need to be mastered.

Experiment

The mechanosensitive ion channels which are embedded in the cell membrane allow ions to pass through the cell membrane. The electrical conductivity of the cell membrane depends on how many ion channels are open or closed. By applying a voltage across the cell membrane, this conductivity can be determined with the measured current. Such measurements are usually performed with electrodes, which are stuck into the egg through the cell membrane. For the experiment on the sounding rocket, the less invasive patch-clamp technique is applied.


 

Construction

The mechanical design of the experiment must be designed and built by the students themselves. In order to fly on the REXUS sounding rocket, the experimantal setup must be designed with an attachment for the measuring chambers. Furthermore, the entire supply units for the measuring chambers must fit into the experiment module.


 

Electronics

For controlling the whole experiment and for communication with the measuring units as well as the rocket a board computer will be used. This board computer must be developed and implemented separately. In addition, a software must be programmed for this board computers. Besides the measured values of the experiment, the board computer must also process and store data from other influences, such as measure the G-values during the flight, on a disk.
