WetLab-2 performs quantitative polymerase chain reaction (qPCR) aboard the micro-gravity environment of the International Space Station in order to research how the stress of micro-gravity affects an organism’s RNA production and gene expression. This on-station qPCR allows researchers to gather information earlier and thereby allow them to modify experiments in a matter of hours rather than wait until the next flight opportunity. After a successful validation flight on SpaceX-8 and follow-up investigation on SpaceX-9, system components must now be adjusted for a new type of biological sample. Specifically, the WetLab-2 facility includes a commercial qPCR instrument (RNA SmartCycler), a sample transfer tool, and a set of fluidic modules. The fluidic modules include a sample prep module (SPM), a pipette loader, and pre-loaded PCR reaction tubes. In order to prepare the SPMs for flight, preparation and kitting of the hardware must be performed in the Clean Room. In May 2019, SpaceX-18 will bring all the WetLab-2 flight hardware to the International Space Station where the experiment will be carried out by the astronauts.
