Human space exploration missions quickly revealed that microgravity, or weightlessness, had profound and unique effects on physical and biological phenomena. Understanding these effects is critical for human exploration and pioneering space—but the study of these effects also advances knowledge on Earth. The International Space Station U.S. National Laboratory is a permanently crewed research facility, observatory, and engineering test bed that can provide Powerful insights into fundamental and applied scientific investigations.
