People who have an interest in science rarely know that part of NASA's mission is serving as a bridge between Americans of all ages, others, (especially teachers) and the world of science.

Many people are trying to make productive use of this epidemic to bone up on subjects that they are curious about. This link is to a wealth of high quality, free NASA ebooks on science topics..

Don't stop there, there is also a great technical search engine that aggregates most of the rest of NASA's collected information. And its all for you, the future investigators and scientists, or past investigators and scientists, and free to access.. This is really an amazing resource. One of the best of its kind on the Web. And it has been for a long time.

NASA takes its educational mission very seriously. If you are a teacher, you should be aware that you can pick up the phone and call the awesome professional librarians at NASA centers' libraries and they will help you find answers to technical questions that are within the scope of anything that NASA does. Which isnt just aeronautics and space. NTRS (link above) is a good intro to the scope of research that goes on there, its very wide. And everybody at NASA is excited about science education, and wants to help you learn if they can, within reasonable limits.
