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…
On the Origin and Thermal Stability of Arrokoths and Plutos Ices
C. M. Lisse, L. A. Young, D. P. Cruikshank +30
We discuss in a thermodynamic, geologically empirical way the long-term nature of the stable majority ices that could be present in Kuiper Belt Object 2014 MU69 after its 4.6 Gyr r…
Cometary ions detected by the Cassini spacecraft 6.5 au downstream of Comet 153P/Ikeya-Zhang
Geraint H. Jones, Heather A. Elliott, David J. McComas +5
During March-April 2002, while between the orbits of Jupiter and Saturn, the Cassini spacecraft detected a significant enhancement in pickup proton flux. The most likely explanatio…
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…
The solar nebula origin of (486958) Arrokoth, a primordial contact binary in the Kuiper belt
W. B. McKinnon, D. C. Richardson, J. C. Marohnic +26
The New Horizons spacecraft's encounter with the cold classical Kuiper belt object (486958) Arrokoth (formerly 2014 MU69) revealed a contact-binary planetesimal. We investigate how…
Color, Composition, and Thermal Environment of Kuiper Belt Object (486958) Arrokoth
W. M. Grundy, M. K. Bird, D. T. Britt +46
The outer Solar System object (486958) Arrokoth (provisional designation 2014 MU) has been largely undisturbed since its formation. We study its surface composition using da…
Overview of initial results from the reconnaissance flyby of a Kuiper Belt planetesimal: 2014 MU69
S. A. Stern, J. R. Spencer, H. A. Weaver +11
The centerpiece objective of the NASA New Horizons first Kuiper Extended Mission (KEM-1) was the close flyby of the Kuiper Belt Object KBO) 2014 MU69, nicknamed Ultima Thule. On 1…
The Lyman-α Sky Background as Observed by New Horizons
G. Randall Gladstone, Wayne R. Pryor, S. Alan Stern +22
Recent observations of interplanetary medium (IPM) atomic hydrogen Lyman-α (Lyα) emission in the outer solar system, made with the Alice ultraviolet spectrograph on New Horizons (N…
The New Horizons Kuiper Belt Extended Mission
S. A. Stern, H. A. Weaver, J. R. Spencer +2
The central objective of the New Horizons prime mission was to make the first exploration of Pluto and its system of moons. Following that, New Horizons has been approved for its f…
The Puzzling Detection of X-rays From Pluto by Chandra
C. M. Lisse, R. L. McNutt, S. J. Wolk +17
Using Chandra ACIS-S, we have obtained imaging Xray spectrophotometry of the Pluto system in support of the New Horizons flyby on 14 July 2015. 174 ksec of observations were obtain…
Plutos interaction with its space environment: Solar Wind, Energetic Particles & Dust
F. Bagenal, M. Horányi, D. J. McComas +23
The New Horizons spacecraft carried three instruments that measured the space environment near Pluto as it flew by on 14 July 2015. The Solar Wind Around Pluto instrument revealed…
The Pluto system: Initial results from its exploration by New Horizons
S. A. Stern, F. Bagenal, K. Ennico +148
The Pluto system was recently explored by NASA's New Horizons spacecraft, making closest approach on 14 July 2015. Pluto's surface displays diverse landforms, terrain ages, albedos…
