NASA astronauts Sunita Williams and Butch Wilmore, who are overstaying in space due to technical issues with their spacecraft, are making the most of their extended stay by conducting experiments, emergency drills, and research on the International Space Station. Their work includes studying plant watering in microgravity, vein scans, and maintaining the station’s life support systems. While their return date is uncertain, the astronauts remain positive and continue contributing to space exploration.
