Habitats Databases

This is the third installment of our  SpaceFund Reality (SFR) rating, focused on space habitats. With this rating we begin to move into areas that are more obviously related to the SpaceFund mission of supporting “frontier enabling” technologies. While the launch database showed a field that is over crowded, many other critical sectors of the space economy are not, and some are frankly, wide open. 

Our research has showed that this sector, space habitats, is still underdeveloped and represents a potential opportunity for investors and entrepreneurs. If one is to believe what Musk, Bezos and governments such as the US and UAE are saying about their plans to both dramatically lower the cost of space access and enable a permanent human presence in space, within a few years we may see a ‘housing shortage’ on the frontier.

It is important to note that space also presents us with many unique challenges, not the least of which is applying traditional terrestrial definitions to things that may seem to be the same in space – or – as often happens – a tendency to create new and exotic names to apply to what on Earth would be common. For example, “habitats” or “space stations.” In actuality both of these are just buildings. They may be located in space, they may be exotic in their form, technology, and structure, but they are still just buildings. They are designed to hold or house people and/or the things and objects that belong to people, or that people use. While some of them may move, such as a habitat orbiting the Earth or a Lagrange point in space, they are not intended or designed to move and deliver people or payloads from point A to point B.

Our research into this sector also highlighted two distinct groups of companies that are actively designing and developing habitats. While these companies are all planning to or are constructing buildings in space, they are working to solve fundamentally different problems depending on the location of those buildings. This means the types of companies, the types of habitats, and the types of engineers and scientists working on those solutions are fundamentally different. For this reason, we have broken these companies into two different database: In-Space Habitats and Surface Habitats.  

If you haven’t already, please consult our SpaceFund Reality (SFR) ratings page to learn more about the rating, its purpose, and the underlying formula, as well as to view a complete list of the SpaceFund sectors of interest. 

How to Use This Table

Sort: Click on the column heading to sort A-Z; click again to sort Z-A.

Search: To search within the entire table, simply type your query into the search area at the top right of the table. If you’d like to search within a specific column, use the search box at the bottom of that column.

Download: You can download this table as an Excel or CSV file by using the icons at the top of the table. You can also print the table.

Screen Size: The database is too big to fit on most screens, so you’ll need to use the scroll bar at the bottom of your screen to scroll right to see additional columns, and continuing scrolling down to see all companies. 

Important Note (Alpha Sort Columns vs Numeric Sort Columns): In the Occupancy, Floor Area, and Volume columns, any figure listed as a “0” is simply a placeholder for unavailable data. This is due to the nature of this table format, and to ensure that the columns sort properly, a numeric character must be included in each cell. So, for example, if a company’s habitat is listed to have a Floor Area of “0” this simply means that this information is not publicly available and the “0” acts as a replacement for “N/A”.  

The Funding column is set to sort alphabetically. Since this column contains alphabetic characters in some cells, it will sort alphabetically, not numerically and so the “-” character has been used to represent unavailable data. All other columns in the table will also sort alphabetically.

Important Note (Companies not Products): This database, and the SpaceFund Reality ratings, are based on COMPANIES, not specific products or technologies. 


How to Provide Updated Data

Have we missed your company? Do you feel that your company should have a different rating? Is the listed data inaccurate or outdated? Do you see missing data for your company? The best way to update your information in this database is to reach out to us directly to provide additional information about your technology, management team, funding history, and company progress. We are also eager to learn about any additional data sources that can help us in our ongoing research, so please feel free to share any resources you know of with our team.

Updates will be published on approximately a monthly basis.
