Evaluation of short-term temporal evolution of Pluto's surface composition from 2014-2017 with APO/TripleSpec
Bryan J. Holler, Maya D. Yanez, Silvia Protopapa +4
In this work we present the results of a spectral observing campaign of Pluto to search for temporal changes in surface composition on 1- to 3-year timescales. Near-infrared spectr…
New Investigations of Dark Floored Pits in the Volatile Ice of Sputnik Planitia on Pluto
S. Alan Stern, Brian Keeney, Rachael Hoover +5
Sputnik Planitia, Pluto's gigantic ice glacier, hosts numerous scientific mysteries, including the presence of thousands of elongated pit structures. We examine various attributes…
Non-detection of water-ice grains in the coma of comet 46P/Wirtanen and implications for hyperactivity
Silvia Protopapa, Michael S. P. Kelley, Charles E. Woodward +1
Hyperactive comets have high water production rates, with inferred sublimation areas of order the surface area of the nucleus. Comets 46P/Wirtanen and 103P/Hartley 2 are two exampl…
The science case for spacecraft exploration of the Uranian satellites: Candidate ocean worlds in an ice giant system
Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +15
The 27 satellites of Uranus are enigmatic, with dark surfaces coated by material that could be rich in organics. Voyager 2 imaged the southern hemispheres of Uranus' five largest '…
Persephone: A Pluto-System Orbiter and Kuiper Belt Explorer
Carly Howett, Stuart Robbins, Bryan J. Holler +40
Persephone is a NASA concept mission study that addresses key questions raised by New Horizons' encounters with Kuiper Belt objects (KBOs), with arguably the most important being "…
