Space is a rather unwelcoming environment for life forms. Together with space and power constraints of a nanosatellite mission, the subteam faces multiple inherent challenges, both in payload design and mission implementation. For example, ensuring the survival of the precious yeast cells during launch conditions is of paramount importance. To tackle this, the subteam optimizes protocols to “turn” yeasts into spores, a form that can survive in extreme conditions. Moreover, “recording” the gene differences in the cells needs to be easy and conducted remotely hundreds of km away from Earth, since the samples/cells cannot be returned. To cope with these difficulties, the subteam uses a library of “tagged” cells with fluorescent “marks”, and it builds a miniaturized microscope for easy optical readout. Growth of the cells needs to be days-long and efficient, and as a result, the members of the subteam employ a complex on-chip culture system, inspired by state-of-the-art microfluidic chips. Lastly, keeping all the instruments “together” and at appropriate positions for the experiment is quite tricky, and thus the team is collaborating with the structural subsystem to create a unibody design to secure the instruments together.
