The Orion spacecraft is the first deep space manned spacecraft in the United States. The first unmanned flight of the Orion spacecraft will be carried out in December 2014, which is next month. At present, NASA is ready for various launches, and the rockets and spacecraft have already been installed.
The manned flight of the Orion spacecraft will not take place until several years later. According to NASA's timetable, manned flights are expected in the early 1920s, and asteroid landing missions will be held around 2025 to show "Orion." "The deep space flight capability of the spacecraft. By the mid-2030s, the follow-up improvements to the Orion spacecraft would begin the mission of manned Mars, carrying astronauts to Mars and landing on the surface of Mars through new planetary landing gear.
Lockheed Martin is a technology leader in the aerospace industry, which has been in the aerospace industry for about 100 years. The company also developed the famous U-2 high-altitude reconnaissance aircraft, the pioneer rocket, the Agena rocket launched the first satellite in the United States, and the SR-71 blackbird reconnaissance aircraft broke the speed record. Recently, Lockheed Martin has also established a space launching agency to develop Mars spacecraft, such as the Mars Reconnaissance Orbiter, which is currently used as a relay communication platform for Curiosity and Opportunity.
The Orion spacecraft is a spacecraft capable of carrying four astronauts capable of flying off-Earth orbit and carrying astronauts into the lunar orbit and asteroids. Lockheed Martin is in charge of the assembly, testing and launching of the Orion spacecraft. Jim Camp believes that the Orion spacecraft is a milestone, completely different from NASA's previous space shuttle, but with a higher technical state than Apollo. With the strong technical strength of Lockheed Martin, the "Orion" spacecraft took only a few years from design to completion.
The first test flight of the Orion spacecraft was named Exploratory Flight Test 1, using the Delta 4 heavy-duty rocket of the Joint Launch Alliance, with a flying altitude of approximately 5,800 kilometers, which is more than 15 times the orbital height of the space station. Due to the high altitude, the speed of the spacecraft re-entry into the atmosphere is also very fast, reaching 32,000 km per hour, which will produce a very high surface temperature, which is a test of the spacecraft insulation system.
NASA engineers expect that the Orion spacecraft will require aerodynamic deceleration after re-entry into the atmosphere. This process will last for a long time, and the parachute deceleration will only work at the right height, so it will be generated during the pneumatic deceleration process. The high temperature is a serious problem for the Orion spacecraft engineers.
The quick stacking door has many functions such as heat preservation and cold preservation, insect and wind prevention, dust insulation and sound insulation. Widely used in underground parking lots, industrial plants, food, textiles, electronics, printing and packaging, automotive assembly, precision machinery, logistics and warehousing and other places.
