Very interesting and ambitious mission.
I just read a little about it. Going to the far side is by far more complicated as going to the side that faces Earth. As communication will be lost as soon as the rocket is behind the moon.
In order to keep contact, there are 2 lunar satellites launched acting as a bridge.
The far side is believed to have a very different composition compared to the near side and part of this mission is to find out why.
Any thoughts, ideas?
I thought maybe the far side receives much more impacts as it's not protected by Earth, so maybe has much more "imported" materials from different areas of space while the near side is still much more Earth like. But that would probably just be surface, I don't know.
