After several delays, NASA astronauts Butch Wilmore and Sunita Williams have finally begun their journey back to Earth in a SpaceX capsule after an extended stay on the International Space Station (ISS). The astronauts departed early Tuesday morning, concluding a mission that extended far beyond its original timeline—the duo, along with two other astronauts, undocked from the ISS at 1:05 a.m. ET, beginning a 17-hour trip to Earth.
