Space engineering is an interdisciplinary field that applies principles of engineering, physics and mathematics to design, build, test, launch and maintain spacecraft. It involves developing new technologies for space exploration, satellite communication, remote sensing, navigation systems, and other applications that require the understanding and manipulation of objects in space. Space engineers work on a wide range of projects from building small satellites to designing complex space vehicles such as the International Space Station (ISS). They also play an important role in developing technologies for future human exploration missions, including Mars colonization efforts. Overall, space engineering is about using science and technology to expand our knowledge and capabilities beyond Earth's boundaries.
