Every year since 2014, NASA has published a software catalog, On Wednesday NASA released a software catalog with over 1,000 free code samples. The free code is divided into 15 categories like robotics, aeronautics, climate simulators, biological sensors and guidance systems. Although the code is free, some restrictions may apply. For some, any U.S. citizen can apply to use it. Others can only be used by other federal agencies. And there is even some open-source code in the catalog. Open-source code can be directly downloaded, but most others require you to create an account, or in some cases sign a government contract or a usage agreement. If you’re in the sciences or like to tinker at home, be sure to check out this year’s NASA catalog.
