According to the Pengpai News Network on September 27, the "Double Asteroid Redirection Test" mission conducted by NASA was successful. The spacecraft of the project successfully hit a previously locked asteroid named "Dimoffus" on the evening of September 26, Eastern Time, and then destroyed the asteroid's flight trajectory. NASA's successful test is not only an important technological advance in the U.S. aerospace field, but also a success finally achieved after many failures in the U.S. aerospace project. This matter will help the United States recover its image as a space power internationally.
According to the plan details previously released by NASA, the goal of this mission is the "dual asteroid system". After repeated discussions, it was finally decided to lock the impact target as the "Dimofus" with a diameter of 160 meters. The asteroid orbits the asteroid 780 meters wide asteroid "Dimofus". Moreover, compared with other asteroids, this asteroid has a larger diameter and is more sure of successful impact. How much has the orbit of the asteroid changed after the completion of this impact mission in the United States? Scientists are using the astronomical telescope for observation and analysis, and an analysis result will be given in the next few weeks or months.
Why the United States launched a plan to impact asteroids is related to the planetary defense plan. The universe where the earth is located is not a safe haven, but it is facing challenges at all times. The reason why the earth is more hit by meteorite rather than by a larger asteroid. The main reason is that there is a circle of Mars and Jupiter . There are as many as hundreds of thousands of asteroids of different sizes. They are like a filter, blocking many large asteroids. Many asteroids that were originally flying towards the earth will soon be broken after they hit the asteroid belt. Even a few who have luckily flew through the asteroid belt may be blocked by the moon.
Although the United States succeeded in this asteroid impact mission, in the past year, the United States' related plans to return to the moon have failed continuously. As the carrier of the US moon landing spacecraft, the US Artemis 1 carrier rocket has given up its launch on September 27, which is the fourth time the rocket has postponed its launch plan. Before this, the rocket was forced to postpone its launch due to the leakage of liquid hydrogen . After completing the rocket fuel test again, new problems were found during the review process, resulting in another delay.
US spacecraft has been twists and turns, while China space has achieved important achievements. According to the CCTV News client on September 27, Taiyuan Satellite Launch Center used Long March 6 launch vehicle to successfully send test 16 and test 17 satellite into the predetermined orbit in the form of "one arrow three satellites", and the launch was a complete success. This was China's three-day three consecutive launches. In addition, in June this year, the Shenzhou 14 spacecraft was successfully launched, and China's aerospace has entered the fast lane of development.
China's rapid progress in aerospace has caused considerable pressure on the United States. The successful collision of the asteroid this time can also make NASA relieved. After all, this is the first planetary defense drill in human history. This kind of scene that only existed in science fiction movies in the past seems to have begun to become a reality. The US side's successful collision is generally believed to have finally moved back to China in the space field.
