Solaris: A Focused Solar Polar Discovery-class Mission to achieve the Highest Priority Heliophysics Science Now
Donald M. Hassler, Sarah E Gibson, Jeffrey S Newmark +33
Solaris is a transformative Solar Polar Discovery-class mission concept to address crucial outstanding questions that can only be answered from a polar vantage. Solaris will image…
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…
The Search for MeV Electrons 2-45 AU from the Sun with the Alice Instrument Microchannel Plate Detector Aboard New Horizons
B. A. Keeney, M. Versteeg, J. Wm. Parker +14
The Alice UV spectrograph aboard NASA's New Horizons mission is sensitive to MeV electrons that penetrate the instrument's thin aluminum housing and interact with its microchannel…
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…
Interstellar Pickup Ion Observations to 38 AU
D. J. McComas, E. J. Zirnstein, M. Bzowski +9
We provide the first direct observations of interstellar H+ and He+ pickup ions in the solar wind from 22 AU to 38 AU. We use the Vasyliunas and Siscoe model functional form to qua…
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…
Long-Term Trends In The Solar Wind Proton Measurements
Heather A. Elliott, David J. McComas, Craig E. DeForest
We examine the long-term time evolution (1965-2015) of the relationships between solar wind proton temperature (Tp) and speed (Vp) and between the proton density (np) and speed usi…
