China3D printingNet, May 5, the National Aeronautics and Space Administration (NASA) is now undertaking the “Artemis Project”. The Artemis project is to bring the first woman and the second man to the moon by 2024. On the surface, it turns out that this is one of the agency’s most ambitious plans and an important milestone in the decade’s space history. To achieve its goals, NASA has been collaborating with the US industry and announced on April 30 that three companies have been selected to design and develop the Human Landing System (HLS) of the program.
Aerospace manufacturers Blue Origin and SpaceX and applied science company Dynetics were selected to design and build three lunar landing systems that can bring humans to the surface of the moon.We also learned that the Dynetics team will be composed of a variety of business and academic experts, including a multidisciplinary faculty research team from the School of Engineering of Tuskegee University. The team will test and evaluate additive manufacturing (AM) material parts, that is, through3D printingProcess produced parts.
Dynetics is a wholly-owned subsidiary of Leidos. It is one of the main contractors and system integrators of the HLS award issued by Next Space Technologies for Exploration Partnerships (NextSTEP-2). The total value of all awarded contracts is close to US$1 billion. Dynetics claims that its mission to design HLS will ensure affordability by using habitat, electricity, heat and other subsystems in the legacy space program. Dynetics expects to achieve short-term reusability and sustainability through the use of modern technology, providing a powerful, commercially supported lander capability that is easily applicable to civil and commercial exploration.
In addition, as the only university research team for the project, researchers from the Tuskegee School of Engineering will test and evaluate additively manufactured materials and parts, including tensile and fatigue testing studies, to evaluate their quality and durability. Meet the environmental requirements of the HLS integrated lander.They hope that a metallurgical evaluation will also help establish these3D printingThe microstructure-processing-performance relationship of materials and parts. Compared with standard-manufactured parts, these parts face different challenges in standardization, qualification and certification.
Heshmat Aglan, Dean of Tuskegee Engineering College in Almaty State, said: “Tuskiki University is honored to join this outstanding team to help the United States send astronauts to the moon by 2024. Our School of Engineering has advanced facilities in additive manufacturing, material processing and characterization, which puts us in a good position to join such an important cause. As the School of Engineering educates the next generation of scientists and engineers, the project provides real-time engineering opportunities.
The Dynetics method of achieving near-term reusability and sustainability of HLS will be the ideal choice for the crew of the system. The surface residence is about a week. Moreover, it can transport up to four suitable crew members to and from the lunar surface.
Dynetics is working on a “single structure” system to land on the moon. Since its announcement in 2011, Boeing is developing a new super-heavy consumable rocket that Boeing is developing for NASA’s future deep space exploration missions. Its vehicle will be launched at high altitude via the 1L Vehicle Space Launch System (SLS). It is expected to provide a basis for mankind’s exploration beyond the earth’s orbit. The next planned improvement of SLS is the Block 1B passenger car, which will use a new and more powerful new exploration advanced class (EUS) to perform more ambitious tasks. The Block 1B vehicle can be launched in a single shot, carrying the Orion crew vehicle and exploration systems such as the Deep Space Habitat Module. In addition, Tuskegee stated that for commercial launches, “Danich” HLS can fly on the United Launch Alliance (ULA) Vulcan Centaur rocket.
Kim Doering, Vice President of Dynetics Space Systems, said: “Dynetics leads this expert team composed of subcontractors. They will bring Americans back to the lunar surface. This team has a history of excellent technology and their contributions will greatly promote space. The future of exploration.”
Dynetics is headquartered in Hansville, Alabama, and has a team of 25 subcontractors working with the project, including ULA, the Italian company Thales Alenia Space, Paragon Space Development and Sierra Nevada.
Development lander pairArtemisThe lunar plan is very important. The three contractors will carry out design work before February next year, when the agency will assess which of them will perform the initial demonstration mission. NASA will then select companies to develop and improve sustainable lander systems, and then conduct sustainable demonstration missions. After these demos are completed,NASAIt is intended to purchase a lander to be transported to the surface of the moon as a commercial space transportation service. At each stage of development, NASA and its partners will learn from the important experience of the early stages to hone the final concept that will be used in future lunar commercial services.
NASA Administrator Jim Bridenstine said yesterday: “The United States is moving towards the last step required to send astronauts to the moon by 2024.” This is the White House space goal for this decade. one.Known as the President’s Space Policy Directive 1, it will “lead an innovative and sustainable exploration program with commercial and international partners to achieve the expansion of mankind throughout the solar system.” The agency’s budget for next year is 25.2 billion. USD, an increase of 12% compared to the previous year, which will accelerate the landing of personnel in 2024MoonThe goal.
