A spacecraft designer is a professional who creates and develops vehicles intended for travel in outer space. They work on various aspects of spacecraft, including structure, propulsion, and systems that support life. Their designs must consider factors like weight, materials, and the harsh conditions of space, ensuring that the spacecraft can withstand extreme temperatures and radiation. These designers often collaborate with engineers, scientists, and other specialists to bring their ideas to life. They may work for organizations like NASA, private space companies, or research institutions. Their ultimate goal is to create safe and efficient spacecraft for missions to destinations such as the Moon, Mars, or beyond.
