There is already an undersea base for training astronauts for the ISS. There is also the ISS, which is already a significantly more challenging environment than Everest. Although it would be nice to have scientific outposts in all of these places, one must bear in mind that these things are very expensive, so the cost/benefit of the scientific value has to be weighed carefully. The cheapest option is not always the best value.

A lunar space station called LOP-G (lunar orbital platform gateway) is presently planned, and although it is a "smaller step" it is being widely attacked for not being useful.

So Everest would be possible? Am I hearing that? No launch costs, you can walk away if you need to (depending on the weather). Has to be cheaper by billions than an orbital station.

It would absolutely be possible to have a base on the peak of Everest. I think you can even get up there with helicopters. The only question is, what would be the scientific value? Astronauts do not go to the ISS just because they love living in cramped quarters for six months... ;)

Live for a year without resupply, generate own heat and power, prove you can survive. And do useful work. Before committing human beings to Mars. The topic of this discussion.
