HOUSTON (NASA PR) — Dozens of experiments are going on at any given time aboard the International Space Station. Research conducted in 2020 is advancing our understanding in areas of study from Parkinson’s disease to combustion.

Space station research results published this year came from experiments performed and data collected during the past 20 years of continuous human habitation aboard the orbiting laboratory. Between October 1, 2019, and October 1, 2020, the station’s Program Research Office identified more than 300 scientific publications based on space station research.
