While I had time to read the last 3 weeks, Cannat's book became my favorite (The sky's guide).

There's a very interesting item !

On march 24th 2020, the Moon will be new (close to the Sun) but also, it will be at its furthest apogee in a very long time!!! 406,688 KM !!!!

This means that :

Someone could organize a manned race around the Moon (a big 8 figure) in such a way that the spacecrafts would be at the other side of the Moon at the moment of apogee.......Meaning they will be the furthest and fastest humans ever (winning a trophy) taking advantage of Newton's laws and only needing one Apogee Kick engine burn from LEO to the Moon and back.
And if it could be a race, knowing the record apogee distance is only a quick moment, they'd be flying not too far from each other....With very interesting pictures of a Full Earth and a Full (farside) Moon!
