The fat five is in place and the five is about to fly to the moon to take samples and return.
Help deepen research on the origin and evolution of the moon, laying the foundation for later missions such as exploring the moon and planet.
News from our newspaper (reporter Lei Jia) On November 17, the Long March 5 Yaowu carrier rocket and the Chang’e-5 probe, known as “Fat Five”, were transported to the Wenchang space launch site after completing the assembly and testing of the technical area. The launch area is scheduled to open at the end of November. The goal of Chang’e-5 is to obtain lunar samples and return to Earth. As China’s first lunar sampling and return mission, the three-step development strategy of the main science and technology project of the lunar exploration project will be successfully completed.
A reporter from the Beijing Youth Daily learned from the National Space Administration that the Yaowu carrier rocket from March 5 long was safely transported to Wenchang Qinglan Port, Wenchang, Hainan by the Yuanwang Transport Fleet in late September, and was transported to the Wenchang space launch site in China by road. . Since then, the rocket has successively completed various preparations, such as final assembly and testing in accordance with the test launch process. On the morning of the 17th, the mobile launch pad exited the vertical test plant at the launch site. After driving smoothly for about 2 hours, the Long March 5 Yaowu launch vehicle was safely transferred to the launch station at launch site 1. Subsequently, after completing the rocket performance inspection and joint test and confirm the final state, the rocket will be filled with propellant and launched according to the procedure. This mission is the second applied launch in the Long March 5 series of carrier rockets. The Tianwen-1 probe, China’s first Mars exploration mission, has been successfully launched before.
In 2004, the China lunar exploration project was established and implemented and a three-step strategic plan of “circumnavigate, fall and return” was determined. The successful implementation of the Chang’e-1 to Chang’e-4 mission has successfully completed the first two steps of the three-step strategy. The Chang’e-5 mission is the sixth mission of China’s lunar exploration project. Automated sampling and return of the lunar surface is planned to help further scientific research on the origin and evolution of the moon. It is one of the most complex and difficult missions in China’s aerospace industry so far. Establish a talent, technology, science, and engineering base for later missions such as moon and planet exploration. It is also another milestone in the development of China’s aerospace industry following the success of artificial ground satellites and manned space flight.
In the 1960s and 1970s, the United States and the former Soviet Union became aware of the return of manned and unmanned lunar samples. The Chang’e-5 mission is expected to gain a new scientific understanding of the formation process and geological evolution of the moon through sampling at the scheduled landing area, scientific exploration of the lunar surface, and comprehensive analysis of samples. posterior moles.
A reporter for the Beijing Youth Daily noted that the leading international scientific journal Nature published an article on November 5 that China will soon launch the Chang’e-5 spacecraft to collect dust and debris in an area in front of the moon that does not it has been explored before. Approximately 2 kg of surface material is removed and returned to the ground through the return device. The article believes that the samples collected by Chang’e-5 may fill a major gap in scientists’ understanding of lunar volcanic activity. Rocks obtained from previous lunar missions by the United States and the former Soviet Union indicate that volcanic activity on the moon peaked 3.5 billion years ago, then weakened and stopped. However, observations on the moon’s surface have found that certain areas may contain volcanic lava that formed only 1 to 2 billion years ago. If the Chang’e-5 samples confirm that the moon is still active during this period, it will rewrite the history of the moon.
