I've heard the moon's soil is akin to finely-ground glass which, due to static electricity, sticks to everything. What a challenging environment for a vehicle.

The last series of moon missions revealed that moon dust is a real problem. Therefore, it might be advisable to cover the crew area, as a way of protecting the crew from the moon dust. Whether is not the crew area is pressurized should be optional. Some longer missions might allow for the moon people to have their face shields open, inside the pressurized cabin, and some short missions might be easier without taking the time to pressurize the cabin. I can definitely see the advantages in having the option to go either way, in regard to a pressurized cabin.

I think considerable thought should be given to protecting the humans from radiation. We were lucky with the Apollo missions, but we never know when a coronal mass ejection will hit the crew. It would be a tragedy to have them killed by radiation due to a lack of foresight. Besides CMEs, there are a lot of other types of radiation that the crew will be exposed to, especially on longer missions. If the goal is to have long term habitation on the moon, protecting the explorers from radiation will be crucial. With no atmosphere, and no magnetosphere around the moon, being on the surface is little different from being in space.

Although the space-farers on the International Space Station are not protected by Earth's atmosphere, they do get most of the benefits of the Earth's magnetosphere.
