Pluto's Surface Mapping using Unsupervised Learning from Near-Infrared Observations of LEISA/Ralph
A. Emran, C. M. Dalle Ore, C. J. Ahrens +3
We map the surface of Pluto using an unsupervised machine learning technique using the near-infrared observations of the LEISA/Ralph instrument onboard NASA's New Horizons spacecra…
Discrepancy in Grain Size Estimation of HO Ice in the Outer Solar System and the Interstellar Medium
A. Emran, V. F. Chevrier
Widespread detection of amorphous and crystalline water (HO) ice in the outer solar system bodies and the interstellar medium has been confirmed over the past decades. Radi…
Uncertainty in Grain Size Estimations of Volatiles on Trans-Neptunian Objects (TNOs) and Kuiper Belt Objects (KBOs)
A. Emran, V. F. Chevrier
We analyze the uncertainty in grain size estimation of pure methane (CH4) and nitrogen saturated with methane (N2:CH4) ices, the most abundant volatile materials on trans-Neptunian…
Thermophysical and Compositional Analyses of Dunes at Hargraves Crater, Mars
A. Emran, L. J. Marzen, D. T. King +1
We analyze thermal emission spectra using the 2001 Mars Odyssey Thermal Emission Imaging System (THEMIS) and the Mars Global Surveyor (MGS) Thermal Emission Spectrometer (TES) to c…
Distribution and habitability of (meta)stable brines on present-day Mars
Edgard G. Rivera-Valentín, Vincent F. Chevrier, Alejandro Soto +1
Special Regions on Mars are defined as environments able to host liquid water that meets certain temperature and water activity requirements that allow known terrestrial organisms…
Voluminous silica precipitated from martian waters during late-stage aqueous alteration
L. Pan, J. Carter, C. Quantin-Nataf +6
Mars' transition from an early "warm and wet" to the "cold and dry" environment left fingerprints on the geological record of fluvial activity on Mars. The morphological and minera…
