• 7. Flying around the earth and the moon! First of all, I'm a little Bai, so I asked the question, why does an aircraft (such as Tiangong, chang'e-3, etc.) have to fly around the earth for a long time before it can run to the moon when it is launched? When it is approaching the moon, it will fly around the moon for a long time before it can land, instead of flying vertically to the moon! Please tell me, and don't copy other people's answers, I've seen the answers given by others, but they are not specific enough! Rockets can't directly raise the aircraft to a certain speed, can they fly around the earth to a certain speed? Why do many people say that they save fuel? Why do they save fuel?
