1、阅读理解(七)科技说明A2019泰安Earlier this year, China achieved a new milestone(里程碑) in space research. On January 3, 2019, Change-4 became the first lunar probe(月球探测器) in history to successfully land on the far side of the moon. The Earths gravity(重力) slows the moons rotation(自转), matching it to the speed of i
2、ts orbit(公转). Therefore, the far side of the moon is almost “dark” and has never been seen. Its this sense of the unknown that makes the far side of the moon such an interesting place for scientific and space research. Being blown by solar(太阳的) winds, the far side may have the special minerals(矿物质).
3、 For this reason, Change-4 will study the effect of solar winds on the lunar surface and any mineral found by the spacecraft. Change-4 is also carrying flower seeds, potatoes and silkworm eggs to see whether life is possible on the moon. If it is, then the moon will become a possible choice for spac
4、e travel in the future. However, research of the “dark” side isnt easy. As the side is blocked(阻断) off from us, radio noise coming off Earth is also blocked. This is why Chinas relay satellite(中继卫星) Queqiao was sent up in May, 2018. Thanks to Queqiao, the communication problem between Earth and Chan
5、ge-4 has been well solved. Power supply(电源供应) is also a challenge to the task. Change-4 gets energy from the sun through its solar panels. As we know, a lunar day has the length of 28 Earth days. After Change-4 was sent up on December 8, 2018, it took the probe over 20 days to orbit the moon to be i
6、n a position to be able to land in moon daylight and use its solar panels. Luckily, everything goes well. Change-4 has worked on the “dark” side for over 5 months. It has sent back many photos of the far side of the moon and has been used to carry out some scientific experiments. The New York Times
