The science process for selecting the landing site for the 2020 Mars rover
Golombek, Matthew P.; Wilson, Sharon A.; Grant, John A. +3 more
The process of identifying the landing site for NASA's Mars 2020 rover began in 2013 by defining threshold mission science criteria related to seeking signs of ancient habitable conditions, searching for biosignatures of past microbial life, assembling a returnable cache of samples for possible future return to Earth, and collecting data for plann…
MarsSI: Martian surface data processing information system
Poulet, F.; Quantin-Nataf, C.; Leyrat, C. +10 more
MarsSI (Acronym for Mars System of Information, https://emars.univ-lyon1.fr/MarsSI/, is a web Geographic Information System application which helps managing and processing martian orbital data. The MarsSI facility is part of the web portal called PSUP (Planetary SUrface Portal) developed by the Observatories of Paris Sud (OSUPS) and Lyon (OSUL) to…
ESA's Planetary Science Archive: Preserve and present reliable scientific data sets
De Marchi, G.; Besse, S.; Vallat, C. +15 more
The European Space Agency (ESA) Planetary Science Archive (PSA) is undergoing a significant refactoring of all its components to improve the services provided to the scientific community and the public. The PSA supports ESA's missions exploring the Solar System by archiving scientific peer-reviewed observations as well as engineering data sets. Th…
On the relationship between surface pressure, terrain elevation, and air temperature. Part I: The large diurnal surface pressure range at Gale Crater, Mars and its origin due to lateral hydrostatic adjustment
Newman, Claire E.; Richardson, Mark I.
The daily variation of surface pressure observed by the Curiosity Rover Environmental Monitoring Station (REMS) is both significantly larger than observed at other landing sites on Mars and larger than simulated for the Curiosity site by global circulation models (GCM). Mesoscale numerical models are able to simulate the large REMS daily pressure …
Estimate of the water flow duration in large Martian fluvial systems
Di Achille, Gaetano; Mancarella, Francesca; Orofino, Vincenzo +1 more
The presence of ancient fluvial systems on Mars, known as valley networks, is considered one of the most compelling evidence that liquid water was once stable on the planet's surface.
To understand the formation mechanisms of these valleys and to acquire information on the ancient climatic conditions of the planet, we determined the formation…The LatHyS database for planetary plasma environment investigations: Overview and a case study of data/model comparisons
André, N.; Fedorov, A.; Budnik, E. +19 more
We present the Latmos Hybrid Simulation (LatHyS) database, which is dedicated to the investigations of planetary plasma environment. Simulation results of several planetary objects (Mars, Mercury, Ganymede) are available in an online catalogue. The full description of the simulations and their results is compliant with a data model developped in t…
Massive stereo-based DTM production for Mars on cloud computers
Tao, Y.; Muller, J. -P.; Sidiropoulos, P. +5 more
Digital Terrain Model (DTM) creation is essential to improving our understanding of the formation processes of the Martian surface. Although there have been previous demonstrations of open-source or commercial planetary 3D reconstruction software, planetary scientists are still struggling with creating good quality DTMs that meet their science nee…
The Multi-Temporal Database of Planetary Image Data (MUTED): A web-based tool for studying dynamic Mars
Jaumann, R.; Hiesinger, H.; Bernhardt, H. +4 more
Multi-temporal spacecraft observations are key to detect and understand surface changes and time-critical processes on Mars. Since the 1970s, the number of orbital observations of Mars has increased to over one million images. The observations have revealed that the surface of Mars is changing due to exogenic processes, including eolian activity, …
Automatic Coregistration and orthorectification (ACRO) and subsequent mosaicing of NASA high-resolution imagery over the Mars MC11 quadrangle, using HRSC as a baseline
Muller, Jan-Peter; Sidiropoulos, Panagiotis; Watson, Gillian +2 more
This work presents the coregistered, orthorectified and mosaiced high-resolution products of the MC11 quadrangle of Mars, which have been processed using novel, fully automatic, techniques. We discuss the development of a pipeline that achieves fully automatic and parameter independent geometric alignment of high-resolution planetary images, start…
PSUP: A Planetary SUrface Portal
Gondet, B.; Poulet, F.; Quantin-Nataf, C. +9 more
The large size and complexity of planetary data acquired by spacecraft during the last two decades create a demand within the planetary community for access to the archives of raw and high level data and for the tools necessary to analyze these data. Among the different targets of the Solar System, Mars is unique as the combined datasets from the …
