Chang'e 5 third letter: I will usher in a key brake

Dear people,

I can't wait for you to reply, I have a little heart to talk to you.

Now I'm a little nervous and a little agitated because I'm about to do my first near-month brake. This moment was too critical, and I only had one chance. If the brakes are too late, I will fly away from the moon and wander in deep space! Although The eldest sister, the second sister, the third sister, and the fourth sister have all accumulated experience for me and made me full of confidence, but this time the engine has a new change, I still have to be more careful. The control team equipped me with a high-level equipment, the Star Sensor, which allowed me to determine my posture by looking at the stars, and my confidence was a little more.

After the first braking, I would go into a large elliptical orbit. I'm going to run three laps on this elliptical track before braking to go to the circular moon track. Why don't I go straight to the orbit around the moon? It's not because people weigh a little bit too much.

In order to remember the main points of operation, I summarized a set of tips ~ "look left, look right, precise braking, decisive and clean, Chang'e 5 is doing sports; speed control, attitude control, take a deep breath, safe and secure full grasp of the moon I am ready."

Everybody hands up!

Chang'e-5, which is about to become a lunar satellite
