In an interesting move, that could benefit a number of private space companies, NASA has released dozens of its patented technologies into the public domain.

The technologies, that were primarily developed for NASA's space missions, could help the space sector at large, which is seeing increasing growth in the private sector, not only from high profile companies such as SpaceX and Virgin Galactic, but from a whole host of SMEs involved in the supply chain.

However, as with cochlear implants, memory foam and freeze-dried food (to name a few NASA-originating technologies), some of the technologies may have terrestrial applications.
