Question: Any thing about the development of aircraft and spacecraft and the building and construction or the the development and operation of energy systems, transport systems, manufacturing systems, machines and control systems or extraction of metals from its ores and development of new materials or the the use of applied science and technology to extract various minerals from the earth?

Hey:D This is a remarkable question!!! As most of those types of engineering aren’t areas I have ever worked in, I don’t really know much about their development and future technologies!:D However, I can answer the one about space! As I work with space technologies, the development is getting to the point where it is becoming so compact against rockets that it doesn’t take up much surface area at all but once in space, they expand up to meters long! So with that, we are starting to apply that principle towards other space technologies and it will hopefully help towards the development of rockets themselves:D I hope this has helped answer some of your question:D
