The US lunar landing plan may be postponed again, as early as 2026?

On November 17, NASA has announced that it will postpone the lunar landing plan from 2024 to 2025. However, the latest audit report released by NASA inspector general's Office (OIG) shows that this time may be postponed again, as early as 2026 < p > OIG is responsible for regular audits of various NASA projects. In its latest report, OIG comprehensively reviewed NASA's Artemis return to the moon program, which hopes to put humans on the moon again and put the first woman and the first colored people on the lunar surface < p > NASA launched the "Artemis" program during the trump administration. In 2019, then Vice President Mike Pence asked NASA to accelerate action to land humans on the moon within five years. But Burns' request is considered difficult to implement. The Artemis program covers a wide range, including a giant launch vehicle called the space launch system (SLS) and the Orion spacecraft that will send astronauts into space < p > meanwhile, SpaceX is developing a spacecraft called starship to transport NASA personnel to and from the lunar surface. However, the starship is still in a very early stage of development and has not been launched into orbit. SLS rockets and Orion spacecraft have not conducted integrated flight < p > OIG emphasized these problems in its report and said that there is still a lot of work to be completed for the "Artemis" plan, which makes it impractical to land on the moon in 2024. The report said: "considering the time required to develop and fully test the manned lander and the new spacesuit, we expect that NASA's time to send humans to the moon will be delayed by a few more years." < / P > < p > just last week, NASA also admitted that landing on the moon in 2024 will not happen. However, the agency only postponed the new goal until 2025. NASA blamed the novel coronavirus pneumonia on the various factors, including the outbreak of new crown pneumonia, part of the project adjustment and the lawsuit initiated by the blue origin, which delayed the development process of the SpaceX lunar lander. p> The OIG report pointed out that the lawsuit did have an impact on the overall schedule, but the agency believed that the development schedule of SpaceX starship was too optimistic. Elon Musk, CEO of SpaceX, continued to make bold predictions for the first major test launch of the Starship and repeatedly claimed that he was ready to conduct the first orbital test flight this year. However, the OIG report estimates that the first orbital flight test of the Starship will be conducted in the second quarter of 2022 < p > the audit document does believe that SpaceX may shorten the time because SpaceX is tested faster than NASA's earlier space flight program. But after the orbital flight test of the starship, there is still a lot of work to be done. The design of a starship depends on the aircraft refueling in orbit so that there is enough propellant to reach the moon < p > SpaceX also needs to test this capability, something it has never done before. Then, the Starship still needs to carry out unmanned flight and landing, manned flight and landing, and many other work to be completed. OIG estimates that the real moon landing attempt will not be carried out until 2026 at the earliest < p > it is not just the Starship project that deviates from the target. OIG's report predicts that the debut of NASA's SLS rocket and Orion spacecraft will also be postponed. At present, NASA is making efforts to prepare for the launch of Artemis I as early as February 2022. It will launch rockets and space capsules for a week-long round moon trip without people. However, OIG expects the flight to be postponed until the summer of 2022. Such delays are not uncommon for SLS and Orion, which were originally expected to test fly as early as 2017 < p > the most shocking discovery in this report may be the huge expenditure on the main projects of the "Artemis" plan. OIG estimates that NASA will spend $93 billion on the project from 2012 to 2025, while the SLS with Orion will cost about $4.1 billion per flight. This is about twice the estimate of the White House Office of management and budget, which claims that SLS costs more than $2 billion per flight. (small) < / P > < p >
