On October 8, NASA officials and SpaceX representatives held a briefing before the third commercial astronaut launch mission (crew-3) of the manned dragon spacecraft, revealing the details of the company's plan to build and use reusable dragon spacecraft to support NASA's mission < p > Figure 1: by the middle of 2022, the number of SpaceX reusable dragon spacecraft will increase to eight < / P > < p > at the briefing, Sarah walker, mission management director of SpaceX dragon spacecraft, revealed that the company will use the new manned dragon spacecraft (c210) to perform the crew-3 mission, which will be sent into space by the reusable Falcon 9 rocket booster b1067 < p > b1067 made its debut on June 3, 2021, when it sent the second upgraded cargo dragon spaceship of SpaceX to the international space station. The crew-3 mission will be the second time NASA will launch astronauts with recycled commercial rockets < p > in April 2021, SpaceX launched NASA astronauts with the recovery Falcon 9 rocket booster (b1062) for the first time to carry out the so-called second commercial astronaut launch mission of manned dragon spacecraft (crew-2). Crew-2 manned dragon spacecraft has also entered orbit to support SpaceX's first manned test flight in May 2020 < p > five months later, SpaceX successfully completed the world's first pure commercial manned space mission, inspiration4. At that time, the company used recycled boosters to launch reusable manned dragon spacecraft. With SpaceX's first manned mission using the twice recovered Falcon 9 rocket, the reusability of the manned dragon spacecraft has been further improved < p > Figure 2: in January 2021, the manned dragon spacecraft C207 flew in orbit for the first time < / P > < p > c210 executing crew-3 will become the third manned dragon spacecraft put into operation by SpaceX. At present, the company is using C206 (endeavour) and C207 (tenacity) to carry out manned missions. Walker also confirmed that the crew-4, recently planned to be launched in April 2022, will also use the new manned dragon spacecraft. By the middle of 2022, the company's manned dragon flying ships will increase to four < p > these four spacecraft will be certified by NASA for at least five missions, which should meet NASA's recent needs for manned dragon spacecraft. However, if it cannot obtain long-term certification for more than five flights, or if the company continues to let professional astronauts and ordinary people fly in manned dragon spacecraft before 2030, it may need more spacecraft < p > but theoretically, if Boeing's Starline spacecraft is finally put into use in 2023 and NASA continues to operate the international space station until 2030 or even longer, SpaceX will only need to perform a manned launch mission for NASA once a year by 2023 < p > Figure 3: in April 2021, the manned dragon spacecraft C206 arrived at the international space station for the second time < / P > < p > in terms of cargo, Walker revealed that SpaceX will debut in its crs-24 and crs-25 missions in December 2021 and may 2022. The other two new cargo dragon spacecraft will increase the company's cargo ships to four. As long as the international space station continues to operate, SpaceX is likely to continue to deliver supplies to it. Between now and 2030, the company needs to launch about 12 to 18 more cargo dragon spacecraft < p > however, when the SpaceX starship is put into use and certified by NASA for daily personnel and cargo missions, the Starship may soon replace the Dragon ship. However, this milestone may take several years to achieve, which means that SpaceX dragon series spacecraft need to continue to fill the top beam for at least the next 5 to 10 years < p > therefore, the number of reusable dragon spacecraft (including manned and cargo) of SpaceX is expected to double from four to eight in the next eight months.
