NASA SmallSat LEARN Forum Briefing: BioSentinel

We will focus on the technologies developed for BioSentinel, primarily the science payloads. One of them, the BioSensor, is a microfluidics-based instrument that houses a series of fluidic cards and manifolds. The fluidic cards can be loaded with microbial organisms to study the effect of the space environment on biology. For BioSentinel, we used the budding yeast as our model organism to study the response to the radiation environment in both low Earth orbit (ISS) and in deep space. The second instrument is a radiation spectrometer. This sensor allows the quantification of ionizing radiation as well as the characterization of the different particles based on the linear energy transfer or LET. Given that BioSentinel launched this past November (Artemis I), part of the presentation will include lessons learned and how we will apply them to future missions, including LEIA. LEIA was recently selected for a mission to the lunar surface on a CLPS lander vehicle, and is primarily based at NASA Ames.
