29P/Schwassmann-Wachmann: A Rosetta Stone for Amorphous Water Ice and CO <-> CO2 Conversion in Centaurs and Comets?
C. M. Lisse, J. K. Steckloff, D. Prialnik +12
Centaur 29P/Schwassmann-Wachmann 1 (SW1) is a highly active object orbiting in the transitional Gateway region (Sarid et al. 2019) between the Centaur and Jupiter Family Comet regi…
A Predicted Dearth of Majority Hypervolatile Ices in Oort Cloud Comets
C. M. Lisse, G. R. Gladstone, L. A. Young +30
We present new, ice species-specific New Horizons/Alice upper gas coma production limits from the 01 Jan 2019 MU69/Arrokoth flyby of Gladstone et al. (2021) and use them to make pr…
The Case for Non-Cryogenic Comet Nucleus Sample Return
Keiko Nakamura-Messenger, Alexander G. Hayes, Scott Sandford +22
Comets hold answers to mysteries of the Solar System by recording presolar history, the initial states of planet formation and prebiotic organics and volatiles to the early Earth.…
Cryogenic Cometary Sample Return
Andrew J. Westphal, Larry R. Nittler, Rhonda Stroud +11
Comets likely formed in the outer regions of the protosolar nebula where they incorporated and preserved primitive presolar materials, volatiles resident in the outer disk, and mor…
Volatile Sample Return in the Solar System
Stefanie N. Milam, Jason P. Dworkin, Jamie E. Elsila +17
We advocate for the realization of volatile sample return from various destinations including: small bodies, the Moon, Mars, ocean worlds/satellites, and plumes. As part of recent…
Small Bodies Tell the Story of the Solar System: A Scientific Rationale for a Multi-Target Small Body Sample Return Program including the Earth-based Laboratory Analysis of Returned Samples
Seth A. Jacobson, Maitrayee Bose, Dennis Bodewits +6
Small bodies are time-capsules of different eras of solar system history from the most primitive materials within the solar system to evolved pieces of larger bodies. A small body…
