Orbital missions refer to space missions where spacecraft are sent into orbit around a celestial body, such as Earth or other planets. These missions can involve satellites, space telescopes, or probes designed to study the body they orbit. They provide valuable data about the atmosphere, surface, and other characteristics of the target, contributing to our understanding of space. One notable example of an orbital mission is the Hubble Space Telescope, which orbits Earth and captures detailed images of distant galaxies and celestial phenomena. Other missions, like the Mars Reconnaissance Orbiter, study planets like Mars to gather information about their geology and climate, aiding future exploration efforts.
