On March 29, according to foreign media reports, on Monday local time, the space transportation company SpaceX under Elon Musk announced that in order to invest more resources in the development of starships, the company had stopped producing new manned dragon spacecraft < p > < / P > < p > currently, SpaceX is working to develop a successor to the manned dragon spacecraft, including the interstellar spacecraft and its improved versions developed for travel to the moon and Mars. The first orbital test launch of the Starship has been delayed for several months due to challenges in engine development and regulatory review < p > stopping the production of manned dragon spacecraft also brings new challenges, because SpaceX needs to learn more about how to maintain the normal operation of the existing space capsule and quickly solve unexpected problems without delaying the implementation of NASA's busy space missions < p > Gwynne shotwell, President of SpaceX, confirmed the planned shutdown of the manned dragon spacecraft and said: "we are completing the final production of the capsule, but we will continue to manufacture parts because we will renovate the existing capsule." < p > schotteville added that SpaceX would retain the ability to produce more manned dragon spacecraft if needed in the future, but she believed that "fleet management is more critical". Currently, SpaceX plans to keep the number of manned dragon spacecraft at four and reuse them to carry out the backlog of manned missions < p > since 2020, SpaceX has used the manned dragon spacecraft to send five groups of NASA astronauts and private passengers into space, and has become the main tool for NASA to shuttle astronauts to and from the international space station. After each flight, the manned dragon spacecraft will be renovated at the SpaceX facility in Florida, which the company calls "dragon land" < p > Garrett Reisman, a retired NASA astronaut and current SpaceX executive, said: "the manned dragon spacecraft also has a life cycle problem. After using it three, four or even five times, you will find something different." < p > he continued: "SpaceX is very good at finding these problems quickly and then taking action to solve them quickly." He was referring to an investigation in 2021, when SpaceX discovered and repaired the leak of the toilet of the space capsule on two manned missions in a few months < p > the manned dragon spacecraft was originally developed for NASA's "commercial astronaut" program, which aims to stimulate private companies to develop manned spacecraft to help NASA shuttle astronauts between the earth and the international space station. To this end, NASA has provided about $3.5 billion to SpaceX and plans to use the manned dragon spacecraft to carry out six manned missions to the space station. Recently, NASA added three more missions to fill the gap left by the delay in the development of Boeing's starliner < p > according to the contract signed with NASA, SpaceX has sent four groups of astronauts to the international space station at a cost of about US $255 million per flight. In 2021, SpaceX also completed a purely commercial space mission composed of ordinary people, sending four passengers into earth orbit for a three-day space trip, including the billionaire entrepreneur Jared Isaacman who funded the flight < p > at the same time, SpaceX also reached an agreement with axiom space, a Houston based space station construction company and space flight service broker, which plans to carry out at least four manned missions. The first so-called AX-1 mission is planned to be carried out in April, sending four entrepreneurs to the international space station for 10 days of scientific research < p > in recent years, musk, the founder and CEO of SpaceX, has always focused on the company's long-term development and reusable starship, which is the core of its ultimate goal of colonizing Mars. Similar to the manned dragon spacecraft, the reusable Falcon 9 rocket and its more powerful variant Falcon heavy rocket also need to be refurbished after each flight, and not every component can perform multiple missions < p > Reisman said: "our goal is to make it operate more and more like an aircraft. After landing, you can repair it and fill it with fuel, and then take off again in a short time. If the Starship achieves its original design goal, it will be able to replace Falcon 9 rocket, Falcon heavy rocket and manned dragon spacecraft at a low price and perform more tasks."
