Are GURPS Tech Books released in wrong order / badly planned?

Check out Kerbal Space Program (a video game about a space program, from rocket design to launch to orbital intercepts and docking/creation of space stations and more). It's got a pretty decent method for showing current and future positions of all objects - exactly a curve, including position indicators for when objects will be close to each other/etc.
