Musk: soon more people will walk on the moon

Share the QR code with wechat scanning code to friends and circles of friends on November 15, US local time on Sunday, Elon Musk, CEO of Tesla, said in response to a twitter user's tweet that the number of people walking on the moon would soon increase the original post listed all astronauts who arrived and walked on the moon, including American astronauts Neil Armstrong and Eugene Cernan. Musk wrote in his reply: "soon, as mankind reaches a new height, the list will become longer!" musk is also the founder of SpaceX, an American space exploration technology company. This company has become a leader in the space field, launched at least 1700 satellite chain broadband satellites and sent astronauts to the international space station musk recently launched a controversial poll on twitter asking fans whether he should sell his 10% stake in the electric vehicle manufacturer. Subsequently, he sold $6.9 billion worth of Tesla shares last week. (small) related reading: Event Background recently, a message spread on the microblog that the American "Artemis" moon landing plan was postponed because of "immature technology" some netizens further questioned why the United States could send astronauts into space more than 50 years ago, but not in the "chip age" as we all know, from the late 1950s to the mid 1970s, the United States and the Soviet Union launched fierce competition around the "space race". During this period, NASA organized and implemented a series of lunar missions code named Apollo program. Although the cost was huge, the plan finally made history and successfully left the first series of human footprints on the moon in December 2017, nearly 50 years after the last human landing on the moon, former US President trump signed Space Policy Directive 1 at the White House, directing NASA to return astronauts to the moon. Two years later, Jim bridenstine, then director of NASA, announced that the new lunar mission would be named after Apollo's twin sister "Artemis", and NASA would systematically land the first group of astronauts including male and female members on the moon within five years as the first step of the Artemis mission, NASA was scheduled to launch the unmanned moon orbiting spacecraft Artemis I at the Kennedy Space Center in November this year to test its deep space exploration system. However, by the end of October, there was news that the original launch plan had been cancelled and the launch time of the spacecraft would not be earlier than February next year so, did Artemis 1 really encounter technical problems as netizens said? Why did NASA delay the launch of the spacecraft? Who should pay for NASA's decision Mingcha technology, is it mature first of all, the statement that the lunar landing delay is "related to technical problems" is not entirely groundless according to a long article published by the New York Times on March 18 this year, in January this year, NASA conducted the first "hot" test on the core stage of the aviation launch system (SLS), a key component of Artemis I. During the test, due to the failure of an element of the SLS system, the computer took the initiative to shut down the launch engine, and the whole ignition lasted only about 1 minute, far from reaching the original 8-minute ignition target to solve this problem, NASA arranged the second hot test run in order to collect all necessary data to ensure the normal operation of the rocket. However, just as the test day was approaching, NASA engineers found in a weekend routine inspection that a valve used to provide liquid oxygen on the SLS core level failed, resulting in the original test had to be postponed despite constant accidents, the fault problem of SLS system was finally solved. In the second test on March 18, after all four engines of the SLS system were ignited, they continued to ignite for 499.6 seconds, successfully achieving the original test goal. After that, NASA conducted 15 months of green on tests on the core level of SLS at the Stennis Space Center in Mississippi, and sent the inspected SLS flight components away from Stannis on April 22, 2021 as the most proud work of NASA in recent years, SLS is claimed by NASA as the most powerful launch vehicle ever built, and it is also an important part of the entire Artemis 1 launch mission. Some people wonder why NASA does not directly use the Saturn V carrier rocket that sent Apollo 11 to the moon 50 years ago, but has to take great pains to develop a new SLS system in its official radio program "Houston we have a podcast", NASA responded that the objectives of this lunar exploration mission are essentially different from the lunar landing plan 50 years ago. NASA hopes to apply the knowledge gained from the experience of orbiting the moon and landing the moon to the exploration and research of Mars landing in the future therefore, in the design and selection of launch vehicles, NASA deliberately used new rocket launch technology, installed two solid fuel rocket boosters on both sides of the core stage of SLS, and used liquid hydrogen engine (ICPs) in the second stage. This enables SLS to generate about 15% more thrust than Saturn V, which lays a technical foundation for NASA to explore deep space fields such as the moon and Mars heavy launch vehicle aviation launch system (SLS) according to CNN, on October 21 local time, the Kennedy Space Center in Florida has put the Orion spacecraft on its developed SLS system in the Kennedy Space Center, an Orion spacecraft is stacked on an SLS rocket CNN wrote that the component erected at the Kennedy Space Center is ready for the final stage of testing, waiting for the arrival of the launch window from February 12 to 27, 2022. Once they pass the test, they will be sent back to the vehicle assembly building of the Space Center for real launch. This seems to imply that the launch of Artemis 1 is secure launch, why delay so what might have caused the postponement of Artemis' lunar landing in the valleyIt is not difficult to find the information related to the "delayed launch of Artemis 1" in the song. Many media, including CNN, the New York Times and business insider, mentioned that the adjustment of Artemis 1 launch time has something to do with the global new crown pandemic and the bad weather represented by Hurricane IDA an article published by space.com on May 16 last year showed that the new crown pandemic had forced NASA to postpone a series of key tests for SLS. Due to the rampant virus, the Stannis Space Center, which originally undertook several of the most critical testing tasks for the core level of SLS system, was forced to suspend almost all field work in March 2020. This has directly affected the work process of Artemis 1 launch mission a public document on NASA's official website shows that although Stannis staff finally returned to the workplace under great epidemic prevention pressure, they adjusted a series of work processes according to epidemic prevention specifications. However, just as everything was going on step by step, in August 2020, seven consecutive hurricanes and tropical cyclones went north from the Gulf of Mexico and swept Stannis, resulting in the center having to stop operation and the test being postponed again it was not until April 2021 that Stannis finally completed the key commissioning test of SLS core level, and then started the sixth round of hot test of rs-25 single engine in August. But at the end of August, a deadly hurricane IDA, second only to Katrina, hit Louisiana, and inadvertently affected Stannis it is not difficult to understand that as a precision science, aerospace needs to carry out rounds of tests to ensure the smooth progress of missions. Many unplanned factors such as epidemic situation and hurricane disrupted the test progress, resulting in the failure to complete the launch task on time however, the epidemic and hurricane only answered the part of "natural disasters" that led to the extension of the lunar landing plan. In an interview with CNN at a media conference call on November 9, Bill Nelson, the current director of NASA, revealed the "man-made disaster" factor in the matter according to Nielsen, the blue origin company led by Jeff Bezos needs to take important responsibility for NASA's failure to advance the Artemis mission as planned because it was abandoned in the competition with SpaceX, a space exploration technology company led by Elon Musk, and NASA to cooperate in the development of manned landing system (HLS), blue origin sued the U.S. government under dissatisfaction and asked NASA to support the development of landing system by the two companies at the same time to sum up this matter in one sentence, the two richest people in the world are scrambling to reach out to NASA for money and cooperation during the seven month litigation period, NASA was expressly prohibited from any contact with SpaceX on HLS topics. It was not until November 5, the day after the federal judge dismissed Lanyuan's lawsuit against NASA, that Nelson found the opportunity to have his first conversation with SpaceX President schottwell on HLS at the same time, Nelson also said that previous congresses did not give sufficient financial support to the manned landing system. In fiscal year 2021, NASA applied for a budget of $3.3 billion for the HLS program, but Congress finally gave only $850 million in September 2020, Forbes magazine published an article saying that NASA estimated that it would cost about $28 billion to complete the entire Artemis Project, which is regarded as a very "cost-effective" investment in this century an official document released by NASA on April 19 this year shows that NASA estimates that the total cost of Artemis mission is expected to reach $86 billion by fiscal 2025 on November 9 local time, CBS reported that NASA had announced on the same day that the launch dates of Artemis I and III would be postponed accordingly due to the extension of the launch mission of Artemis I. NASA is expected to complete the launch of Artemis III manned spacecraft in 2025, which means that it is impossible for the United States to complete the mission of returning to the moon by 2024 set by the trump administration to sum up, Artemis 1 did encounter technical problems during the project test, but the problem has been solved. In addition, the space technology used in the Artemis mission is very different from the Apollo program half a century ago, and can not be compared together there are a variety of factors leading to the postponement of Artemis' mission to the moon. In addition to the direct impact of the epidemic and extreme weather, the "mutual pinch" between Bezos and musk and the shortage of R & D funds also hinder the normal progress of the project process
