1st Trans-Earth Injection (TEI) burn:
At 9:54 on 12th December 2020 Beijing Time (01:54 UTC), the Chang'e 5 orbiter after 6 days of parking orbit around the moon, performed the First Trans-Earth Injection (TEI) burn.
This changed the orbit from a near circular lunar orbit to a high elliptical lunar orbit with an apoapsis of 200 kilometers.
The main purpose of the Trans-Earth Injection (TEI) burn is to prepare for the 2nd TEI burn that should take place 24 hours later, sending the spacecraft into a trajectory heading back to Earth, that would end with a landing on Earth by 18th December 2020.
