There's lots of real engineering and science (plus the teensiest bit of fictionalized science) in Escape Velocity.
There's robotics, material science, microbiology, and even xenobiology. Here are some videos on the real stuff I researched before I began writing.
Snottites can be found in caves like this and are slimy just like you'd expect. This video has the advantage of revealing how hard it is to navigate in caves. That might or might not be important in Escape Velocity. Just sayin'.
Metallic Hydrogen-What would it be like to discover a new material?
The robot in Escape Velocity is quite different. Still, I think working for Disney would be cool.
