The source said that Jeff Bezos, founder of blue origin, launched a project called Jarvis within the company, and its main task is to develop a fully reusable new Glen rocket < p > < / P > < p > in late May, a rumor about the blue origin new Glenn rocket was revealed on the social media website frequented by aerospace enthusiasts < p > it is said that blue origin changed the main structural material of the new Glen rocket from aluminum alloy to stainless steel. The relevant content has aroused great interest because it means that blue origin began to imitate SpaceX, which uses stainless steel in the research of starships and super heavy rockets. In addition, this adjustment also indicates that the new Glenn rocket development project, which has lagged behind the original plan for several years, will be further delayed < p > but a source later confirmed that this statement was false. Blue origin did not replace the material of the first stage booster of the new Glen rocket with stainless steel < p > however, three sources confirmed that blue origin began to develop a fully reusable second stage for the new Glen rocket, which may use stainless steel propellant storage tanks < p > the main objective of this strategy is to reduce the overall launch cost of the new Glen rocket. The second stage of the new Glen rocket has a diameter of 7 meters and is equipped with two be-3u rocket engines, which is very expensive. Jeff Bezos, founder of blue origin, is looking for ways to make the whole rocket more economical < p > an industry source familiar with the plan said: "it's about whether the new Glen rocket made a profit or a loss when it was launched." < p > Jarvis project < / P > < p > the reusable rocket second stage project is not only inspired by SpaceX to build rockets with stainless steel. By making the entire new Glen rocket fully reusable, Bezos is following Musk's practice of recycling super heavy boosters and starships < p > in 2016, when musk officially announced the Starship project, many people in the industry doubted that he could build a large reusable launch system. In early 2019, after musk announced that the main structural material of the rocket would be changed from carbon fiber to low-cost stainless steel, they were still skeptical. Although stainless steel is cheaper and more heat-resistant on re-entry, it weighs about five times more than composites < p > according to the source, Bezos has been asking blue origin executives for information about the second stage of the reusable rocket. But many consultants told him that this approach was unlikely to work. Bezos also seems to have been told that SpaceX's rapid prototype iteration and "learning from failure" test methods lack relevant processes and are unlikely to succeed < p > over the past year, however, Bezos noticed that SpaceX launched a prototype starship and successfully landed it. This is one of the reasons why he decided to let blue origin start a project called "Jarvis". The main content of this project is to develop a reusable second stage rocket. According to the source, Bezos has distinguished some of its R & D contents from other R & D activities of the company and told the person in charge that innovation can be carried out without restraint < p > Jarvis project is obviously named after Jarvis, the artificial intelligence character in Marvel film, and the progress is very fast. This fall, blue origin will conduct preliminary testing of stainless steel tanks at its Florida plant. If this method proves feasible, further tests will be carried out. At least for now, the company's plan is to launch a new Glenn rocket with a consumable second stage before transitioning to a fully reusable second stage in the mid-1920s. This fully reusable launch system is now seen by blue origin as the key to competing with SpaceX to launch large payloads < p > it is unclear whether the Jarvis project leader will report to Bezos or Bob Smith, CEO of blue origin < p > other projects < / P > < p > in addition to launching rockets, blue origin seems to pay more attention to space activities. According to sources, Bezos recently approved two other major projects, one related to space propulsion technology and the other focused on developing and demonstrating how to use the resources of the moon and other planets in situ < p > for resource development projects, a source said that blue origin formed the best space resource team in the industry almost overnight. The company hired Vlada stamenkovic, a research scientist at NASA's Jet Propulsion Laboratory, to head the team, as well as several other key industry personnel. The goal of this project is to enable mankind to live on the moon for a long time and develop resources for the benefit of the earth（ Chen Chen) < / P > < p >
