SpaceX launches 4 astronauts for NASA

SpaceX launched four astronauts to the International Space Station for NASA on April 27, less than two days after completing a flight chartered by millionaires. It's the first NASA crew comprised equally of men and women, including the first Black woman making a long-term spaceflight, Jessica Watkins. The astronauts were due to arrive at the space station Wednesday night, 16 hours after their predawn liftoff from Kennedy Space Center. They will spend five months at the orbiting lab. Both SpaceX and NASA officials stressed they're taking it one step at a time to ensure safety.
