The first four years of JWST operations have revolutionized our understanding of small solar system objects, with a particular focus on measuring spectral features near wavelengths of 3um. But challenges remain in identifying major materials that can relate ice-poor carbonaceous asteroids to their formation environments, troubling efforts to test major predictions of solar system evolutionary models. I will discuss how the results of our JWST program (GO #4028), targeting the Jovian satellite system, have complicated our views of primitive planetesimal migration, and how many of these challenges were already identified by ground-based observers. I will also discuss the need for improved laboratory understanding of key materials, as well as the likely impact of future observations of Jupiter’s inner satellites (JWST GO #10716).
