Physical Analysis of Bennu Samples Reveals Regolith Production by Collisional Disruption on Near-Earth Asteroids

R. -L. Ballouz, A. J. Ryan, R. J. Macke +25

Owing to the extremely low gravity of small near-Earth asteroids (NEAs), it has been assumed that impact-generated rock fragments escape into space and thus do not contribute to th…

Hypotheses for Triton's Plumes: New Analyses and Future Remote Sensing Tests

Jason D. Hofgartner, Samuel P. D. Birch, Julie Castillo +14

At least two active plumes were observed on Neptune's moon Triton during the Voyager 2 flyby in 1989. Models for Triton's plumes have previously been grouped into five hypotheses,…

Evidence for geologically recent explosive volcanism in Elysium Planitia, Mars

David G. Horvath, Pranabendu Moitra, Christopher W. Hamilton +2

Volcanic activity on Mars peaked during the Noachian and Hesperian periods but has continued since then in isolated locales. Elysium Planitia hosts numerous young, fissure-fed floo…

Climate simulations of early Mars with estimated precipitation, runoff, and erosion rates

Ramses M. Ramirez, Robert A. Craddock, Tomohiro Usui

The debate over the early Martian climate is among the most intriguing in planetary science. Although the geologic evidence generally supports a warmer and wetter climate, climate…

Seismicity on Tidally Active Solid-Surface Worlds

T. A. Hurford, W. G. Henning, R. Maguire +8

Tidal interactions between planets or stars and the bodies that orbit them dissipate energy in their interiors. The energy dissipated drives internal heating and a fraction of that…

The geological and climatological case for a warmer and wetter early Mars

Ramses M. Ramirez, Robert A. Craddock

The climate of early Mars remains a topic of intense debate. Ancient terrains preserve landscapes consistent with stream channels, lake basins, and possibly even oceans, and thus t…

Solar system science with the Wide-Field InfraRed Survey Telescope (WFIRST)

B. J. Holler, S. N. Milam, J. M. Bauer +30

We present a community-led assessment of the solar system investigations achievable with NASA's next-generation space telescope, the Wide Field InfraRed Survey Telescope (WFIRST).…

Towards High-Resolution Mercury Global Topography from MESSENGER Orbital Stereo Imaging - A Prototype Model for the H6 Quadrangle "Kuiper"

Frank Preusker, Alexander Stark, Jürgen Oberst +3

We selected approximately 10,500 Narrow Angle Camera (NAC) and Wide-Angle Camera (WAC) stereo images obtained by the MESSENGER spacecraft during its orbital mission with average re…
