Science opportunities with solar sailing smallsats
Slava G. Turyshev, Darren Garber, Louis D. Friedman +25
Recently, we witnessed how the synergy of small satellite technology and solar sailing propulsion enables new missions. Together, small satellites with lightweight instruments and…
Spitzer's Solar System Science Legacy: Studies of the Relics of Solar System Formation & Evolution. Part 1 - Comets, Centaurs, & Kuiper Belt Objects
Carey Lisse, James Bauer, Dale Cruikshank +15
In its 16 years of scientific measurements, the Spitzer Space Telescope performed a number of ground breaking and key infrared measurements of Solar System objects near and far. Ta…
White Paper on Improvements to the NASA Research and Analysis Proposal and Review System
Paul K Byrne, Christina R. Richey, Julie C. Castillo-Rogez +1
We review some key issues pertaining to NASA's Research and Analysis programs, and offer recommended actions to mitigate or resolve these issues. In particular, we recommended that…
Disk-Integrated Thermal Properties of Ceres Measured at Millimeter Wavelengths
Jian-Yang Li, Arielle Moullet, Timothy N. Titus +2
We observed Ceres at three epochs in 2015 November and 2017 September and October with ALMA 12-meter array and in 2017 October with the ALMA Compact Array (ACA), all at ~265 GHz co…
Ceres' opposition effect observed by the Dawn framing camera
Stefan E. Schröder, Jian-Yang Li, Marc D. Rayman +12
The surface reflectance of planetary regoliths may increase dramatically towards zero phase angle, a phenomenon known as the opposition effect (OE). Two physical processes that are…
Search for Dust Emission from (24) Themis Using the Gemini-North Telescope
Henry H. Hsieh, Yoonyoung Kim, Alan Fitzsimmons +1
We report the results of a search for a dust trail aligned with the orbit plane of the large main-belt asteroid (24) Themis, which has been reported to have water ice frost on its…
The Reclassification of Asteroids from Planets to Non-Planets
Philip T. Metzger, Mark V. Sykes, Alan Stern +1
It is often claimed that asteroids' sharing of orbits is the reason they were re-classified from planets to non-planets. A critical review of the literature from the 19th Century t…
Surface Albedo and Spectral Variability of Ceres
Jian-Yang Li, Vishnu Reddy, Andreas Nathues +21
Previous observations suggested that Ceres has active but possibly sporadic water outgassing, and possibly varying spectral characteristics in a time scale of months. We used all a…
Delivery of dust grains from comet C/2013 A1 (Siding Spring) to Mars
Pasquale Tricarico, Nalin H. Samarasinha, Mark V. Sykes +7
Comet C/2013 A1 (Siding Spring) will have a close encounter with Mars on October 19, 2014. We model the dynamical evolution of dust grains from the time of their ejection from the…
A Search for Satellite around Ceres
A. Bieryla, J. Wm. Parker, E. F. Young +5
We conducted a satellite search around the dwarf planet 1 Ceres using Hubble Space Telescope and ground-based Palomar data. No candidate objects were found orbiting Ceres in its en…
The Dynamical Environment of Dawn at Vesta
Pasquale Tricarico, Mark V. Sykes
Dawn is the first NASA mission to operate in the vicinity of the two most massive asteroids in the main belt, Ceres and Vesta. This double-rendezvous mission is enabled by the use…
The Dust Trail of Comet 67P/Churyumov-Gerasimenko between 2004 and 2006
Jessica Agarwal, Michael Mueller, William T. Reach +3
We report on observations of the dust trail of comet 67P/Churyumov-Gerasimenko (CG) in visible light with the Wide Field Imager at the ESO/MPG 2.2m telescope at 4.7 AU before aphel…
Distribution and properties of fragments and debris from the split comet 73P/Schwassmann-Wachmann 3 as revealed by Spitzer Space Telescope
William T. Reach, Jeremie Vaubaillon, Michael S. Kelley +2
During 2006 Mar - 2007 Jan, we used the IRAC and MIPS instruments on the Spitzer Space Telescope to study the infrared emission from the ensemble of fragments, meteoroids, and dust…
Planetary Science Goals for the Spitzer Warm Era
Carey Lisse, Mark Sykes, David Trilling +6
The overarching goal of planetary astronomy is to deduce how the present collection of objects found in our Solar System were formed from the original material present in the proto…
The formation of Encke meteoroids and dust trail
William T. Reach, Mark V. Sykes, David Lien +1
We observed comet 2P/Encke with the Infrared Space Observatory ISOCAM on July 14, 1997 from a particularly favorable viewing geometry above the comet's orbital plane and at a dista…
