If I were a scientist, what kind of immigration base would I build on a certain planet?

First of all, the first step is to set up an outpost on the moon and Mars, that is, the initial base, so as to get familiar with the local environment. There are more than 10 professional astronauts to take care of it, mainly to mine some minerals and extract oxygen. At present, if oxygen can be extracted from the lunar soil, other substances can be found to experimentally extract water needed for human survival, supply plant nutrition and raw materials needed for industrial production. And establish an observatory to develop astronomical observations; Establish laboratories and do some scientific experiments that cannot be realized on earth, such as developing new materials and collecting local data on geography, minerals and atmosphere, so as to lay the foundation for future official bases.

The second step is to expand the outpost into a formal base, managed by more than 100 astronauts and scientists, so that ordinary tourists can develop tourism, build large-scale solar power stations, large-scale ore collection stations, production factories and spacecraft factories, expand residential areas and build more spacecraft docks. And engaged in large-scale foreign development and production, which is the beginning of foreign economy and lays the foundation for future immigrant cities.

The third step is the gradual formation of immigrant cities. At this time, a large number of ordinary people have moved there and become real alien human residents, and the commercial trade between aliens and the earth will flourish. Needless to say, the rest!
