Hello. I am trying to choose between studying chemical engineering (MSc) or getting a master's degree as an engineer specializing in math&physics (yes, you can do that in my country). For this I have questions: 1)Are chemical engineers needed in Space agencies? Perhaps working on spacecraft propulsion? 2) Am I being realistic if I hope to get a job in the ESA if I choose to study math&physics? Honestly, I think I'd prefer studying chemical engineering, but I really like physics as well. If there is no realistic chance for me to get a job in a space agency as a chemical engineer, then this will probably tip the scale over to math&physics, for me.
