land on the far side of the moon will be possible after many missions when they will be confident with the hardware, when there will be more funds, when they will send comm-GPS sats around the moon, when they end the exploration of the near side, etc.

the only way to have a few more days on the near side is to land in different places with different delays of the CLV launch, but...

1. a few days more don't change so much the risk of the 1.5 l.a. because the delays that will kill a mission never will be of "a few days"

2. it's very dangerous to trasform the (risky) moon missions in a sort of "last-minute-space-travel"

3. if the astronauts will be trained to land in a given "location" of the moon (then, they will know ALL of that location and what to do there) they can't land in another (UNKNOWN) location due to a "train-delay" because they can't know (nor be trained) for the entire moon!

4. land in different locations at every launch is VERY EXPENSIVE because, at every mission, all the moon-hardware is lost; since NASA funds are low (and the missions, with that funds, only a dozen) NASA must use one or two landings' sites, send all the hardware with a few cargo-LSAM and REUSE many times the hardware to explore the moon via surface
