Scientists at NASA's Marshall Space Flight Center in Huntsville, Alabama, clean equipment and prepare for shipment of the ring sheared drop payload currently set for launch on Northrop Grumman 16 the first week in August, 2021. The payload studies the formation of potentially destructive amyloid fibrils, or protein clusters, like those found in the brain tissue of patients battling neurodegenerative diseases. Such illnesses may damage neurons, the drivers of the human nervous system. Experimentation in microgravity provides the opportunity to study amyloid fibril formation in conditions more analogous to those found in the human body than can be studied in a ground-based laboratory environment.
