NASA needs to get it's s**** together!
I have a lot of sympathy for NASA's problems here.
Bulk fuel tanks for cryogenic LH2 fuel change their dimensions very significantly and hydrogen makes steel go brittle in short order. It can diffuse into the metal matrix.
Sad news is if they miss this next launch window then it will have to go
right back to the starting blocks and have various battery checks/swaps.
Space flight is difficult and dangerous. It should be left to robotics
unless and until we find something that our latest robots cannot handle.
I am with Martin Rees the UK Astronomer Royal on this.

I would personally still like to see one tourist visit to one of the
later Apollo sites just to rub conspiracy theorists noses in it.
The Apollo 11 landing site should be left untouched though.
