The manned "Dragon" spaceship of SpaceX was launched in Florida on the 5th EDT, and four astronauts from the United States, Japan and Russia will be sent to the International Space Station. The live broadcast of the National Aeronautics and Space Administration (NASA) showed that at 12:00 on the 5th, the Falcon 9 rocket carrying the "Dragon" spacecraft was launched from the Kennedy Space Center in Florida. The spacecraft will arrive at the International Space Station at 16:57 on the 6th and automatically dock with it. At that time, NASA will broadcast the docking process. (On October 5 local time, the SpaceX manned "Dragon" spacecraft was launched in Florida and four astronauts from the United States, Japan and Russia were sent to the International Space Station.) In this mission, code named "Crew-5", the four people who took the "Dragon" spacecraft to the International Space Station were NASA astronauts Nicole Mann and Josh Kassada, Japan Aerospace Exploration Agency astronaut Raoda Guangyi and Russian astronaut Anna Kikina. NASA said on its website that after the arrival of four astronauts on the "Crew 5" mission, the number of people on the International Space Station will increase to 11. In a few days, the four astronauts performing the "Crew - 4" mission will return to Earth. NASA said that the four astronauts on the "Crew 5" mission will work on the International Space Station for six months. During this period, they will carry out scientific research on cardiovascular health, biological printing and fluid movement in microgravity environment. According to NASA Director Bill Nelson, the "Crew - 5" mission will complete more than 200 scientific experiments and technical demonstrations. The "Dragon" spaceship is the first manned spaceship built by a private enterprise in the United States to transport astronauts to and from the space station. The launch on the 5th was the sixth time that the spaceship transported astronauts to NASA. In addition, the "Dragon" spacecraft also sent two civilian groups into space. (Liu Xinshe)
