The launch of crew-2 was originally scheduled for the early morning of April 22 local time Launch mission. But the company and NASA announced that they would delay the launch by one day because of bad weather conditions along the rocket's flight path. Now, SpaceX will launch at 5:49 a.m. EST on April 23 (17:49 p.m. Beijing time on April 23). < / P > < p > Bob cabana, director of NASA's Kennedy Space Center, confirmed: "I'm sure you've heard that we're going to have to postpone the launch of crew-2 by one day and we won't be able to launch as scheduled. Although < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%8F%91%E5%B0%84%E5%9C%BA "> the weather near the launch site may be very good, but we are worried about the bad weather conditions along the way after the launch, so we decided to delay the launch to prevent failure." < / P > < p > the manned Longfei ship is equipped with a special launch escape system, which allows the spacecraft to push the crew to a safe place in case of emergency during the rocket launch. Therefore, the weather team of the 45th space wing must not only monitor the weather at the launch site, but also monitor the weather conditions along the rocket's trajectory, as well as any potential landing points that the capsule may splash on in the event of a possible "flight stop". < / P > < p > earlier, Brian cisek, launch weather officer for the 45th space wing, said the weather at the launch site looked perfect for launch, but it was better on Friday. < / P > < p > < b > Figure 2: about to perform SpaceX's second commercial manned mission < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%AE%87%E8%88%AA%E5%91%98 "> astronauts < / a >, from left to right are NASA astronauts Shane jinbro and Megan MacArthur, European Space Agency astronaut Thomas pesquet, and Japanese astronaut xingchu Zhangyan < / b > < / P > < p > the crew of the manned Longfei spacecraft includes NASA astronaut Shane jinbro Kimbrough and Megan McArthur, as well as European Space Agency astronaut Thomas pesquet and Japanese astronaut Masako. They will stay on the space station for six months, do a lot of research and experiments, and then return to earth later this year. < / P > < p > if Friday's launch goes as planned, crew-2 astronauts will board the manned dragon spacecraft early Friday morning and arrive at the international space station at 5:10 a.m. on Saturday. The astronauts will join seven other astronauts on the space station, including four from SpaceX's first commercial manned mission (crew-1) for NASA, who will return to earth on April 28. < / P > < p > SpaceX is one of two commercial companies that transport NASA astronauts from the international space station, with a contract worth billions of dollars. Another company is Boeing, but its Starline spacecraft has yet to make a second unmanned test flight. Crew-2 is SpaceX's third manned mission for NASA after launching crew-1 in November 2020 and performing demo-2 (first manned) demonstration mission in May 2020. (small) < / P > < p >
