Space exploration is the pursuit of knowledge about the Universe through human space flight and robotics. It aims to advance science and technology, inspires new generations, and promotes international cooperation and national pride in achievement.
The science of space exploration is a rich, multidisciplinary field. Since the first rocket launch, scientists and engineers have developed spacecraft to fly by, orbit, land on, and probe remote celestial bodies such as the Moon, Mars, and Saturn’s rings. Spacecraft development focuses on increasing efficiency, reducing cost, and improving safety and reliability.
National governments have given high priority to scientific research in space, which includes studying the Sun and its planets, stars, and galaxies. It has led to major projects such as the Curiosity Mars rover and the Cassini–Huygens mission to Saturn and its moons. Other space research includes the monitoring of Earth’s atmosphere, climate, oceans, and land by satellites.
Space stations and colonies require specialized infrastructure to accommodate space explorers for extended periods of time. These facilities will need living quarters, science laboratories and telescopes to conduct studies and produce supplies of food, water, and energy. They will also need transportation to get to and from these bases, including EVA equipment for lunar or Mars surface excursions.
Space exploration will require a new generation of scientists, technicians, engineers, and other professionals to operate and maintain the space infrastructure. The effort will also foster creativity, critical thinking, and problem-solving skills that are important for many of the challenges that society faces.
