§ 4.1 The Space Environment and Manufacturing -- Advantages and Disadvantages
The manufacturing environment in orbital space is much more flexible than on Earth, and more flexible than that on the lunar surface.
Some mission scenarios to date have employed conventional Earth processes in order to reduce perceived risk and give a "worst case scenario", while citing probable major improvements by using space-specific processes. For example: "Facility mass and power estimates for the basic manufacturing equipment ... have been based on data for similar Earth production equipment. For in-space or lunar surface use the mass and perhaps the power consumption associated with these facilities can be reduced considerably." (General Dynamics)
When serious private sector plans are made, they will undoubtedly look for greater efficiency and effectiveness than some of the government funded studies to date, and will go into greater detail in plans for a space manufacturing facility (SMF), though they will probably be marked "Company Confidential".

This is a volunteer, unpaid role at this point in time. A limited paid role would be considered on a tight budget, such as for at least bug fixing with some minor improvements, and/or a security review of our code before it goes online publicly.

This website has a lot of text content, so here are some suggestions on how to navigate and also recognize pages you're seen already vs. still unseen pages in the SiteMap.
There are 2 ways to browse this website:
- The SiteMap page.
The pulldown menu and the SiteMap are the same tree of pages and links. The pulldown menu offers + and - for expand and collapse sections/subsections/sub-subsections... of the tree, sometimes multiple levels, whereas the SiteMap has everything expanded with no + or - expand and collapse options so the SiteMap is much longer, compared to the pulldown menu if not fully expanded. You may just choose which of the two formats you prefer at a particular time.
The SiteMap colors links red which you have already visited, vs. normal blue for still unseen. It is convenient to browse the SiteMap in one tab or window, and opening pages in other tabs/windows (Ctrl-click or right-click), such as browsing the whole SiteMap to skip pages you've already seen and to choose to open pages you haven't read yet.
The pulldown menu doesn't change the color of seen pages, unfortunately, unlike the SiteMap. However, using the pulldown menu, you can quickly browse the list of sections and other pages without leaving the page you're on. The SiteMap is a separate page of its own.
