Microfluidics system for the MOREBAC astrobiology experiment module : Design of a cubesat module

Abstract: In order for humans to travel further into space, spacecrafts must be able to sustain life for several months. One way to do this is to have a biological life support system containing bacteria to provide the necessary eco-system to support life. The aim of MOREBAC is to evaluate whether it is possible to resurrect these kinds of bacteria while in space and after several months in a freeze dried state. MOREBAC will be one of several experiments onboard the Cube-Sat MIST, and will be the smallest experiment of its kind to be executed in orbit. This project focused on the the resurrection and keeping the bacteria alive for the experiment period, which includes fluid actuation of nutrient, pressure- and temperature controlof the bacteria environment. A prototype of the system was designed, built and tested to evaluate whether the techniques used are suitable for a space mission. It was deemed that the design was a valid option but several suggestions for improvements were also given.
