According to foreign media reports, NASA (hereinafter referred to as "NASA") announced the latest plan for the United States to return to the moon. It can be seen that returning to the moon program NASA is still working with commercial companies to perform this task.
It is reported that NASA plans to invest 2.6 billion US dollars, and cooperate with 9 commercial companies, including small startups, and giant companies such as Lockheed Martin. NASA will work together to develop the robotic lander and landing system, and then plan to mine natural resources on the lunar surface.
According to NASA's promise, it will build a human lunar base within ten years. The specific first lunar missions will be launched in early 2019. NASA said it is opening a new chapter in the US exploration of space, which will return to the moon and arrange for humans to stay on the surface of the moon.
NASA Director Bridenstin believes that humans may land on the moon's surface in the next decade, and they will use the moon's resources and ship these resources to Mars. He also said that this latest plan marks the substantial progress of the United States returning to and staying on the surface of the moon. The future space base may be international, and the United States hopes to dominate these space programs. It also hopes that multiple suppliers will be able to compete on cost and innovation.
It is reported that Bridenstin was the US Navy pilot before he became the director of NASA. He served as an Oklahoma state legislator. In April of this year, he was appointed by Trump as the director of NASA. And, this latest lunar exploration program is part of the Trump 1 space command strategy.
NASA announced its return to the moon program, and the first lunar missions will be implemented early next year.
Since then, Bridenstin has revealed a lot about the plan. He said that he is currently building a space station. It is called the "deep space channel", the space station will run on the orbit around the moon, and the astronauts can exist on the orbit around the moon.
At the same time, in the same way as SpaceX launches rockets, Bridenstin said in an interview that he hopes to reuse the lander so that the lander can travel to and from the surface of the moon.
"Our idea is to prove our ability to eliminate the potential risks of space exploration and to prove that human physiology can adapt to space life. Ultimately, the goal of human landing on Mars is achieved."
As for working with commercial companies, NASA said that building partnerships with a number of commercial companies is an important step towards long-term scientific research and human exploration of the moon. NASA's commercial lunar payload service program encourages small start-up companies to develop 1100-2200-pound robot landing vehicles. These landing vehicles are planned to use NASA's astronaut payload to reach the surface of the moon.
In the future, NASA plans to sign multiple contracts for commercial lunar payload services in ten years. Among them, it is expected that the earliest landing lunar contract mission will begin in 2019, and the first batch of space materials transported by commercial companies will not be later than December 31, 2021.
Spirals are mainly used for stirring, mixing and other functions in pipeline transportation. The spiral surface of the screw conveyor has a solid spiral surface. , belt spiral surface and blade spiral surface transparent form.
The cold rolling mill is an advanced equipment that continuously rolls blades from strip steel. By adjusting the position (roll offset, feed height, roll pressure, guide wheel, etc.), it can roll out blades of various specifications required.
Advantages of cold rolling layout:
It has the advantages of high production efficiency, saving raw materials, good blade quality, high hole diameter, and good wear resistance.
The structures that affect the rolling shape include the material and thickness of the strip, the offset of the roll, the feeding height, the rolling force of the roll, the different specifications of the guide wheels and blades, and the increase in the temperature of the roll during the rolling process. After years of construction, the contract developed this continuous cold-rolled propeller, which has the advantages of smooth surface, high hardness, wear resistance, one-time forming, and continuous no welds.
