In the next 20 days or so, the Chang'e-5 mission had a series of key nodes, such as landing on the lunar surface, sampling on the lunar surface, returning to the earth, etc., and these key nodes were also carried out at night like launches. Could it be that Chang'e 5 is on the moon as a night shift? What is the doorway to the schedule? Xiaoming asked Chang'e to take you to understand.

Sister Changwu, why do you go on a business trip to the moon and leave in the middle of the night? In order to get up and watch the live broadcast, I set five alarms!
Chang'e 5
Oh I'm sorry, I don't want to stay up late, but if I want to go to the moon to dig for treasure, I have to leave at night.
Why?
This back to the moon, there is more work to do, planing to go back and forth between the two ends of the earth and the moon, after I go to the moon, I have to brake first into the moon orbit, and then land on the lunar surface, dig up the soil, and then rise from the lunar surface, transport the soil, prepare for returning to the earth, so many things, adding up to a busy day.
One day? So soon to be back?
No, no, I'm talking about a day on the moon, a month's day, which is equivalent to thirteen or four days on Earth. Because of the tight time and heavy tasks, I had to rush to the moon at dawn, and the surface of the moon should be dug up to take advantage of the full sunlight on the moon during the day, so that I could rely on solar energy to charge and accumulate strength to work, and after 48 hours of working on the lunar surface, I would take off from the lunar surface, fly into the air to hand over the lunar soil samples, and finally leave before the moon was dark. That way, I can stay overnight on the moon and return to Earth as soon as possible.
Oh, so you go to the moon and take a "red-eye flight"?
Haha, almost, back and forth are "red-eye flights". Although it was hard work, I worked on the moon and was a day shift. And on earth, the remote command and remote contact staff of me are on the night shift.
Oh, why do we have to stay up late to see you?
It has to do with the relationship between the Sun, the Earth, and the Moon. You see, the sun is here, the workers on Earth are here, I'm here on the moon. When I arrived, I began to work, during this period, because the earth rotated, when the local staff was in the daytime, but they were facing me on the moon, shouting across the earth, I could not hear it clearly. Only at night, when the staff are facing me, can I know every move 380,000 kilometers away.
Oh, I kind of understand, face to face, to hear more clearly, to see more accurately.
That's right, that's it!
