What are uses of computer in space exploration?

Answer 1

Space exploration requires complex calculations using many variables. These apply to astronomical information for planets, moons, and other bodies, as well as the precise accelerations and trajectories for spacecraft and probes. On Earth, travel on the surface or in the air can be controlled effectively by human coordination and relatively simple vehicles. In space, small errors or miscalculations can create serious problems that cannot be easily corrected. Computers provide faster and more flexible handling of data, both in planning a mission and in analyzing parameters during a mission. Without them, effective space exploration would be nearly impossible.
