@nasawebb will yield a wealth of science about Saturn.
This image shows a giant Saturnian storm that was observed at mid-infrared wavelengths by the European Southern Observatory’s Very Large Telescope in 2011. The warm gases powering the storm make it glow brightly compared to the rest of the planet.

While Webb’s mission lifetime after launch is designed to be at least 5-1/2 years, it could potentially last 10 years or more. As a result, it could watch Saturn’s northern summer proceed through the autumnal equinox as the southern hemisphere warms to spring. That would nearly complete Saturn’s 30-year seasonal cycle of observations begun when Cassini arrived during southern summer in 2004.
