MARSWRF Prediction of Entry Descent Landing Profiles: Applications to Mars Exploration
Zorzano, María-Paz; Fonseca, Ricardo Morais; Martín-Torres, Javier
In this paper we use the Mars implementation of the Planet Weather Research and Forecasting model, MarsWRF, to simulate the Entry, Descent and Landing (EDL) vertical profiles from six past missions: Pathfinder, Mars Exploration Rovers Opportunity and Spirit, Phoenix, Mars Science Laboratory Curiosity rover, and ExoMars 2016 (Schiaparelli), and com…
Retrieval of Chemical Abundances in Titan's Upper Atmosphere From Cassini UVIS Observations With Pointing Motion
Gao, Peter; Fan, Siteng; Li, Cheng +3 more
Cassini/Ultraviolet Imaging Spectrograph (UVIS) Far-UV observations of stellar occultations at Titan are well suited for probing its atmospheric composition and structure. However, due to instrument pointing motion, only 5 out of tens of observations have been analyzed. We present an innovative retrieval method that corrects for the effect of poin…
A Robust Ground-to-Image Transformation Algorithm and Its Applications in the Geometric Processing of Linear Pushbroom Images
Geng, Xun; Xu, Qing; Lan, Chaozhen +1 more
Linear array cameras are widely used in the fields of aerial and space remote sensing. The ground-to-image transformation plays a significant role in the geometric processing procedures of linear pushbroom images, which is time-consuming due to multiple iterative calculations. Moreover, the detectors of the linear array may exhibit a curved shape …
Introducing a New Inventory of Large Martian Landslides
Crosta, G. B.; Frattini, P.; Valbuzzi, E. +1 more
Landslides have been observed in different terrestrial environments and also on planets, satellites, and asteroids. Long runout landslides are strongly dependent on the initial mass position, material and slope path properties, topographic relief, and presence of volatiles. Therefore, landslides represent a means for the description of rock proper…
The Web-Based Interactive Mars Analysis and Research System for HRSC and the iMars Project
van Gasselt, S.; Gwinner, K.; Michael, G. G. +9 more
Web-based planetary image dissemination platforms usually show outline coverage of available data and offer querying for metadata as well as preview and download. While the usual form of presenting multiorbit data sets is to merge the data into a larger mosaic, for change detection purposes it is essential to maintain the individual images as an i…
