If Spacex succeeds, the first ship of colonists will arrive on Mars sometime during the 2020's. Developing the spacecraft is a monumental undertaking and I am amazed that a private company may be able to put it all together to get us there with potentially hundreds of people and a lot of cargo. But what do they do when they get there? Spacex may develop the transportation but there is a lot more new technology needed once we get there to support these people such as habitats, food farms, power plants, water and atmosphere generators, recycling systems, and a whole litany of other technologies to support the residents. The transporter design that Elon Musk presented was merely a shell. I suspect Spacex will spend all their development time and resources filling in the interior with all the vital systems needed to get there. Other innovators will need to step up to develop the infrastructure needed for the Mars village.
I know that NASA is working on various technologies, but I think none intended to support several astronauts for a short stay. Some companies are working on some aspects of a permanent settlement, such as Bigelow inflatable habitats, but I suspect there are many missing teeth in developing the necessary systems. So I have several related questions:
What organizations,companies, or research groups are working on major subsystems needed for a Mars village that readers on this site are aware of?
Are there any emerging organizations/leaders who can potentially coordinate the efforts of the many focused technology efforts to build a community consistent with scale or Spacex's transport plan?
