Four astronauts arrived at the John F. Kennedy Space Center in Florida on Sunday to prepare for a trip to the International Space Station (ISS). An airplane brought the astronauts to Kennedy from the U.S. space agency’s training center in Houston, Texas. The three Americans and one Japanese are set to leave for the ISS Saturday night, if weather conditions permit. The flight will be the second crew launch for SpaceX, a private company working with NASA to carry astronauts to space. The first SpaceX flight, in May 2020, made history. It was the first time a private company had launched astronauts into Earth’s orbit. SpaceX built and operated the Falcon 9 rocket and Crew Dragon spacecraft that carried two NASA astronauts to the space station.
