Exploration of the Ice Giant Systems: A White Paper for NASA's Planetary Science and Astrobiology Decadal Survey 2023-2032
Chloe Beddingfield, Cheng Li, Sushil Atreya +9
Ice giants are the only unexplored class of planet in our Solar System. Much that we currently know about these systems challenges our understanding of how planets, rings, satellit…
The Science Case for Spacecraft Exploration of the Uranian Satellites
Richard J. Cartwright, Chloe B. Beddingfield, Tom Nordheim +14
The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus' classical moo…
Evidence for ammonia-bearing species on the Uranian satellite Ariel supports recent geologic activity
Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +6
We investigated whether ammonia-rich constituents are present on the surface of the Uranian moon Ariel by analyzing 32 near-infrared reflectance spectra collected over a wide range…
Initial results from the New Horizons exploration of 2014 MU69, a small Kuiper Belt Object
S. A. Stern, H. A. Weaver, J. R. Spencer +202
The Kuiper Belt is a distant region of the Solar System. On 1 January 2019, the New Horizons spacecraft flew close to (486958) 2014 MU69, a Cold Classical Kuiper Belt Object, a cla…
The Geology and Geophysics of Kuiper Belt Object (486958) Arrokoth
J. R. Spencer, S. A. Stern, J. M. Moore +75
The Cold Classical Kuiper Belt, a class of small bodies in undisturbed orbits beyond Neptune, are primitive objects preserving information about Solar System formation. The New Hor…
Probing the regoliths of the classical Uranian satellites: Are their surfaces mantled by a layer of tiny H2O ice grains?
Richard J. Cartwright, Joshua P. Emery, William M. Grundy +3
We investigate whether the surfaces of the classical moons of Uranus are compositionally stratified, with a thin veneer of mostly tiny H2O ice grains (<= 2 micron diameters) mantli…
