Martian Ozone Observed by TGO/NOMAD-UVIS Solar Occultation: An Inter-Comparison of Three Retrieval Methods

Aoki, S.; Vandaele, A. C.; Daerden, F. +16 more

The NOMAD-UVIS instrument on board the ExoMars Trace Gas Orbiter has been investigating the Martian atmosphere with the occultation technique since April 2018. Here, we analyze almost two Mars Years of ozone vertical distributions acquired at the day-night terminator. The ozone retrievals proved more difficult than expected due to spurious detecti…

Mars Methane Sources in Northwestern Gale Crater Inferred From Back Trajectory Modeling

Yung, Y. L.; Luo, Y.; Lin, J. C. +3 more

During its first seven years of operation, the Sample Analysis at Mars Tunable Laser Spectrometer (TLS) on board the Curiosity rover has detected seven methane spikes above a low background abundance in Gale crater. The methane spikes are likely sourced by surface emission within or around Gale crater. Here, we use inverse Lagrangian modeling tech…

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…
