iss057e000185 (10/8/2018) – Biomolecule Sequencer [a flight certified Nanopore MinIon] for the BEST experiment floating in front of Window 7 in the Cupola module. Earth is in the background. The Biomolecule Sequencer seeks to demonstrate, for the first time, that DNA sequencing is feasible in an orbiting spacecraft. A space-based DNA sequencer could identify microbes, diagnose diseases and understand crew member health, and potentially help detect DNA-based life elsewhere in the solar system. -- NASA

A) A close-up, exploded view of the spinpod optical system and diagram of operations. To take fluorescence measurements, excitation light first passes through a bidirectional optical probe from the LED light source to illuminate liquid cultures encased in a spinpod. Fluorescence emission then returns through the optical probe to the spectrometer for measurement, through a longpass filter that reduces signal from the excitation wavelength. To take optical density measurements, a red LED mounted toward the optical probe but on the opposite side of the spinpod illuminates the spinpod ("OD illumination hardware"). This light passes through the spinpod and to the spectrometer without filtering. The spinpod is housed in two joined Carrier Extenders with additional Carrier Extenders placed inline as spacers. B) Photograph of the system diagrammed in panel A; optical probe is in front. Tape has been applied to the outside of carrier extenders to shield the optical path from external light. C) and D) Rear and front close-up views, respectively, of the OD illumination hardware. -- biorxiv.org
