It has been nearly 5 years since Chang'e-4, a Chinese spacecraft, made the first soft landing on the far side of the moon at 10:26 am on 3rd January 2019. It is the first time that a spacecraft has made it. The far side is the part of the moon that always faces away from the earth.
After it landed on the ground, the spacecraft took the first photo of the"dark side"of the moon, and sent it back to the earth through the Queqiao relay satellite(中继卫星).The scientists launched the satellite into space in May, 2018.
"What we know about the far side of the moon is from orbiters (轨道飞行器), from Russia, the US, European countries, China and India,"Andrew Coates, a professor of Physics at University College London, told a reporter. China sent Chang'e-4 into space from the Xichang Satellite Launch Centre in December,2018. Sending a spacecraft to the far side of the moon isn't easy, because the far side is covered in craters(火山口). Some of its mountains are higher than Qomolangma, the highest mountain on the earth.
What's more, we can't see the far side because it takes the moon about 28 days to move around the earth with the same side always facing our planet. Direct communication with the earth is impossible on the far side of the moon, so communications must go through a communication satellite. That was why scientists launched the Queqiao relay satellite.
Today, I want to tell you about a new app called Lost &. Found at school. You just need to search for the names of the things on the app. And then you can find them. Now look at these things on the app. Some students lost them this week.
