I wonder what they will do about the Radiation problem. The Appollo astronauts in the 70's narrowly avoided death because they went to the moon when it wasn't being hit by solar flares, they didn't know at the time that the radiation from a solar flare would kill the crew if they were on the moon. I think the moon and the Earth are hit by Solar Flares quite often but the Earth's magnetic field is very powerful and deflects the flares away; the moon doesn't have a magnetic field so the surface of the moon gets bombarded by radiation.
I was also wondering why train drivers are paid more than bus drivers in England, I think it is more difficult to drive a bus than a train. Is it because they have a better trade union or something like that? I don't know. I always see RMT on the news organising strike action.
Sometimes the world doesn't make sense.
