Of some interest, this is the proposed imaging breakdown by time: 2.0 % observation calibration 4.9 % instrument calibration 7.9 % solar system (comets, asteroids, kuiper belt objects, etc) 16.1 % exoplanets 17.2 % nearby galaxies 20.4 % galactic (debris disks, etc) 31.5 % distant galaxies and cosmology There's a whole huge breakdown of what instrumentation calibration entails: https://www.stsci.edu/jwst/about-jwst/history/science-operations-design-reference-mission-sodrm/instrumentation-calibration-programs https://www.stsci.edu/jwst/about-jwst/history/science-operat...
