Constraining the Origin of the Jupiter Trojans by In Situ Measurement of Volatiles, Minerals, and Ices

Abstract

As the KISS Trojans program comes to a close, we report here on our achievements in this venture that began with a KISS workshop in 2012, “In Situ Science and Instrumentation for Primitive Bodies”. The original workshop brought together a diverse group (see Appendix B) that set out to tackle an ambitious goal – to find a way to test predictions of dynamical models (such as the Nice model, named after the founding research group in Nice, France), that have recently led to a radically new understanding of solar system formation. We aimed to do so through interdisciplinary collaboration between the planetary dynamics communities that have formulated (and largely dominated discussion of) these new ideas, and the meteoritics and cosmochemistry communities who would no doubt be involved in any in situ mission to an outer solar system body.
