As part of its continuing program of education and outreach, NASA has released 22 printable models of NASA and European space probes, asteroids, and planetary landscapes for the hobbyist and space enthusiast.
The 3D models are available from the NASA website for free and are printable on any desktop 3D printer using plastic filaments. It’s the latest in a long tradition of NASA science, technology artwork made available to the public going back to its founding in 1958.
The activities embedded in the programs make the subjects more engaging for the students as well as the teacher.
