On September 28, members of the security advisory group of NASA revealed that the second manned dragon spacecraft operated by SpaceX, a US space exploration technology company, will fly around the international space station (ISS) for the first time in many years < p > David West, a member of NASA's Security Advisory Group, said that SpaceX's manned dragon spacecraft will fly 360 degrees around the international space station from early November to mid November, which is the first time that the U.S. crew has conducted a similar maneuver since the space shuttle < p > similar "fly around" maneuvers were common in the space shuttle era. At that time, the United States and Russia assembled the international space station in low earth orbit (LEO) from scratch. Flying around was mainly to record this important historical process. In 2011, NASA and the Russian space agency plan to fly around for the last time to capture the last mission scene of the space shuttle Discovery < p > since then, although sometimes the spacecraft needs to be repositioned in space and occasionally there are some maneuvers around the international space station, the complete maneuver around the international space station did not resume until October 2018 and was completed by the Russian Soyuz spacecraft. At that time, close to the 20th anniversary of the international space station in orbit, many spectacular photos were captured during the flight around the international space station < p > now, after the Soyuz spacecraft has been flying around for more than three years, SpaceX plans to continue this tradition as early as November 2021, making the manned dragon spacecraft the third spacecraft to fly around the space station and conduct comprehensive flight observation of the 450 ton orbital outpost < p > the crew of the mission includes European Space Agency astronaut Thomas pesquet, JAXA astronaut Akiko, and NASA astronauts Shane kimbough and Megan McArthur < p > in the next five to six weeks, SpaceX plans to separate the currently in orbit cargo dragon spacecraft c208 from the international space station and return to earth, which means the completion of the crs-23 resupply mission and freeing up the docking port for the arrival of the new manned dragon spacecraft (c208). SpaceX plans to launch the third batch of NASA commercial astronauts (crew-3) on October 31. The crew includes Raja Chari, Thomas marshburn, Kayla Barron and Matthias Maurer. They will meet crew-2 members briefly on the international space station < p > after the handover, crew-2 and its manned dragon spacecraft will be able to leave the international space station for the first 360 degree flight survey in many years, and return to earth after more than six months in orbit < p > due to years of technical and project delays, Boeing, another partner of NASA's "commercial astronaut" project, may not be ready to support astronaut launch until the end of 2022 at the earliest. This means that more manned dragon spacecraft will enter space before Boeing Starline spacecraft can carry out manned flight. In other words, SpaceX will alone ensure that NASA astronauts can travel to and from the international space station for two or more consecutive years. (small) < / P > < p >
