NASA and SpaceX are set to return the Crew-8 astronauts from the International Space Station after over 200 days in orbit. The crew is scheduled to undock from the ISS no earlier than 5 PM today. Their mission has focused on more than 200 scientific experiments, including studies on motion sickness and human movement in microgravity. Splashdown is expected off the coast of Florida on Friday, contingent on favorable weather conditions, which have improved since initial forecasts.
