NASA, which already has tons of great resources for education, has a great site about the Orion Multi-Purpose Crew vehicle. The Orion MPCV is the future for American manned space flight. It will be the exploration vehicle that will carry astronauts to space and then return them.
The site has information on the MPCV, information on the design, construction and engineering of it, and cut away views of the space craft.
This is a great way to get students excited and interested about STEM subjects and talk to them about the future of manned spaceflight.
