What will happen to the Chang’e 5 orbiter which will return the collected samples to earth? Will it burn up in the atmosphere like Hayabusa, or is an extented mission planned?

$\begingroup$ There are something like four separate spacecraft in one here, so this will be quite an interesting mission to follow! Here are two pretty good animations: youtu.be/waF2pzTGX4I and even better youtu.be/xMet268iaKc $\endgroup$– uhohCommented Nov 24, 2020 at 20:28

Neither NASA nor Xinhua news, in their detailed descriptions of the overall mission, mention any role for the orbiter after the returner separates from it in Earth orbit to land.
Any extended mission for the orbiter that requires equipment beyond what is needed to retrieve Lunar samples would have eaten into the payload budget and probably reduced the size of the sample. So it seems safe to assume that the mission planners chose to maximize prestige, which comes from hauling rocks back. The orbiter may fly for some time afterwards, but as little more than a beeping Sputnik.

$\begingroup$ Thank you for your homage to my "beeping Sputnik" question :-) Long after Chandrayaan-1 stopped its beeping it did briefly return to usefulness as a target for some very fancy radar work! Why was the 100m Green Bank dish needed together with DSN's 70m Goldstone dish to detect Chandrayaan-1 in lunar orbit? $\endgroup$– uhohCommented Nov 24, 2020 at 22:20
