Voyager 1 and the James Web Telescope have similar missions. Voyager 1’s imaging subsystem helps to search for new rings by “map the radial and azimuthal distribution of material in the ring plane”. It attains comprehensive multi-spectral imaging across all satellites, determines rotation speeds and spin axis orientations, examines Triton's surface features at resolutions below 2 km, and explores for any unidentified moons (NASA, n.d). The images of the planetary atmosphere captured by the cameras also help data analysts determine the wind velocities of each region observed (NASA, n.d). Being launched in 1977, the Voyager 1 had the most technologically advanced imaging system at the time. However, the modern spacecraft imaging system of the James Web Telescope has improved based on the Voyager 1 imaging system and helps scientists to further study other planets with the images captured with the latest technology available. The Imaging Science Subsystem (ISS) of Voyager 1 was used t
