Experimental sites in hostile locations for the testing of space
equipment already exist. They are used by space agencies and are
typically located in deserts or volcanic regions.
With this scheme, anyone can have a go, for a weekend, or longer.
The accomodation is a set of inflated fabric
domes, in one of said
hostile localities. Facilities are intentionally very
basic; not uncomfortable, just limited , a sort if high-tech
camping. Food is nutritious, but also limited - as is water, and
energy use.
What you can bring with you is limited by both mass and volume,
probably to just a few kilos. There are few windows, and if you
want
to go outside, you have to wear an environment suit.
Partcipants would have a duty roster - time in the control room,
time spent outside on science missions, time working in the
hydroponic greenhouse.
The idea is to be able to experience for a few days what life for an
exploration team would be like.
The "trip" would include a day's training on how things work.
There's a small TV in the communal area, but all it ever shows is
Total Recall on a continuous loop.
