Dear Jundroo SR2 Team

I was thinking that it would be easier to traverse the terrain on different planets by using caterpillar tracks since they have a larger surface contact area than wheels. I was also thinking about adding an option to a rocket's control panel to make the engine optimized for vacuum performance. Lastly, I want to ask that Aerospike engines (linear and toroidal) be added to SR2.

Thank-you for all your hard work, and keeping us updated with the latest improvements to SR2!
