Astronauts Return to Earth From the International Space Station

Three crew members who have been living and working aboard the International Space Station returned to Earth today, landing in Kazakhstan after opening a new chapter in the scientific capability of humanity’s premier microgravityThe condition of perceived weightlessness created when an object is in free fall, for example when an object is in orbital motion. Microgravity alters many observable phenomena within the physical and life sciences, allowing scientists to study things in ways not possible on Earth. The International Space Station provides access to a persistent microgravity environment. laboratory. Highlights from the research conducted while they were aboard include the National Lab-sponsored investigation designed to grow larger versions of an important protein implicated in Parkinson’s disease.
