Space flight is still a high -risk industry. On February 21st, Israel spent $ 100 million. The initial person who launched its lunar exploration in the American Rockets was originally scheduled to reach the moon watch on April 11, but it failed on the way to February 25.Add its uncertainty.
The US President signed SPD-1, the first space administrative order to return to the moon in the United States in December 2017, and ordered the NASA of the US Space Administration to deploy to return to the moon to build a foundation for flying Mars and other deep space exploration.The SPACE FORCE Space Army's third space administrative command SPD-3 in the SPACE FORCE Space Army for many years.Johnson Freese, an expert at the School of War of the United States Naval War, said to the media on January 3, 2019: China is striding in space, and the United States is unhappy.The US Space Army is mainly for countermeasures to counter China.This is the permanent of human feelings.
The United States and NASA have announced their plans to return to the moon with the assistance of private enterprises.Private enterprises involved in the development of manned moon landing technology will propose the design concepts of the design of the moon landing system, space refueling system and synsacting spacecraft before March 25, 2019.NASA will select several from it to enter the preliminary research and development stage, and then choose at least two to enter the physical construction test demonstration stage. The first demonstration was conducted in 2024, including the launch of the lunar rail space station Gateway on the moon.The second demonstration task, the period of 2028 brought 4 astronauts back to the moon for 7 days.NASA claims that the moon landing will build a sustainable and reusable moon system. Participating companies will only bear the development costs of 10 ﹪ -20 ﹪.
China, so far, is very successful but slightly conservatively conservative, falling, and back to three steps to take the moon exploration mode.
Ring: In October 2007, Chang'e 1 and October 2010 Chang'e 2 were carried out.After completing the task of surveying and mapping, Chang'e 2 flew to L2, and took the lead for the later relay satellite bridge. On December 13, 2012, it flew to No. 4179 small planets.In December 2013, he took the Yue Rabbit No. 1 lunar car to the front of the moon.Chang'e No. 4 landed on the back of the moon with Yutu No. 2 lunar car in January 2019; back: Chang'e 5 will be launched in December 2019, and will bring about 2 kg of moon soil to the earth.
The main tasks of Chang'e 7 (expected to be 2023), Chang'e 6 (2024), and Chang'e 8 (2027) are the construction of the moon base.The manned landing of the moon is not yet announced, and the moon may be landed in the 1930s.
It is said that China's space budget is only 10 ﹪ in the United States, about 2 billion U.S. dollars, but China has basically possessed the threshold technology of manned landing and returned safely.The momentum, the first manned of the moon in the United States will be divided into a watershed significance.
Russia used to explore beef ears for a while, but today is not the same as that in the past, Russian space budget was only half of China. China News Network said on November 6, 2018 that Russia plans to build a long -term moon base for human access.Study the moon and land on the moon for the first time in 2030.
The EU, the European Space Administration ESA on January 22, 2019 announced that it was signed with the Aleian Rockets Group to discuss the feasibility of landing the moon by 2025.
In terms of space detection, India, Japan, and Israel set off on the shoulders of the giant United States, and now they need US NASA's data technical support.Indian Monthly Boat No. 2, the last time it is scheduled to be launched on January 3 this year, but is postponed again.The manned and aerospace mission will be completed by 2022, and then they will be placed in the field in this field. Regardless of the Indian elite British -style mouth, it will never recognize the culture and always inspire China.
