Nasa

In 1995, the NASA Systems Engineering Handbook (NASA/SP-6105) was initially published to bring the fundamental concepts and techniques of systems engineering to the National Aeronautics and Space Administration (NASA) personnel in a way that recognized the nature of NASA systems and the NASA environment. Since its initial writing and its revision in 2007 (Rev 1), systems engineering as a discipline at NASA has undergone rapid and continued evolution. This revision (Rev 2) of the Handbook maintains that original philosophy while updating the Agency’s systems engineering body of knowledge, providing guidance for insight into current best Agency practices, and maintaining the alignment of the Handbook with the Agency’s systems engineering policy.

Launch your business to new heights with out-of-this world innovation
For over half a century, NASA has delivered a continuous stream of innovative accomplishments that have inspired the world. Neil Armstrong walking on the moon, the space shuttle pioneering reusable space planes, Mars rovers exploring the red planet–the list goes on.

Most observers would point to the 1969 Apollo moon landing as the single greatest accomplishment of NASA, yet prominent scientists, engineers, and public officials were questioning the purpose of the U.S. space program, even at the height of its national popularity.
