“Space has been my dream and passion since I was a child. As an adult, I always wanted to work in a sector that is in constant evolution. Now I am an aerospace engineer! The space sector is made up of passionate people and there is something new to learn every day. What fascinates me most is how space commonly seems very distant and futuristic, but in reality, space applications help our daily lives more than (almost) everyone realises.”
