Oxygen isotope fractionation in the Martian atmosphere induced by CO photolysis and O formation
Tatsuya Yoshida, Shohei Aoki, Hiromu Nakagawa +8
The enrichment of heavy isotopes of volatile elements in the Martian atmosphere indicates that Mars lost a large portion of its atmosphere through escape to space. Recent atmospher…
Anatomy of Empirical Transit Spectra of Mars based on TGO/NOMAD
Shohei Aoki, Yuka Fujii, Hideo Sagawa +10
Transit spectroscopy is a powerful tool for probing atmospheric structures of exoplanets. Accurately accounting for the effects of aerosols is key to reconstructing atmospheric pro…
A case study on the impact of interplanetary coronal mass ejection on the Martian O(1S) 557.7 nm dayglow emission using ExoMars TGO/NOMAD-UVIS observations: First Results
Aadarsh Raj Sharma, Lot Ram, Harshaa Suhaag +6
We report, for the first time, the impact of an interplanetary coronal mass ejection (ICME) on the recently discovered O(S) 557.7 nm dayglow emission in the Martian atmosphere.…
Planetary Exploration Horizon 2061 Report, Chapter 3: From science questions to Solar System exploration
Véronique Dehant, Michel Blanc, Steve Mackwell +31
This chapter of the Planetary Exploration Horizon 2061 Report reviews the way the six key questions about planetary systems, from their origins to the way they work and their habit…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
Machine Learning for automatic identification of new minor species
Frederic Schmidt, Guillaume Cruz Mermy, Justin Erwin +9
One of the main difficulties to analyze modern spectroscopic datasets is due to the large amount of data. For example, in atmospheric transmittance spectroscopy, the solar occultat…
No evidence of phosphine in the atmosphere of Venus by independent analyses
Geronimo Villanueva, Martin Cordiner, Patrick Irwin +24
The detection of phosphine (PH3) in the atmosphere of Venus has been recently reported based on millimeter-wave radio observations (Greaves et al. 2020), and its re-analyses (Greav…
Strong variability of Martian water ice clouds during dust storms revealed from ExoMars Trace Gas Orbiter/NOMAD
Giuliano Liuzzi, Geronimo L. Villanueva, Matteo M. J. Crismani +12
Observations of water ice clouds and aerosols on Mars can provide important insights into the complexity of the water cycle. Recent observations have indicated an important link be…
Virtual European Solar & Planetary Access (VESPA): a Planetary Science Virtual Observatory cornerstone
S. Erard, B. Cecconi, P. Le Sidaner +21
The Europlanet-2020 programme, which ended on Aug 31st, 2019, included an activity called VESPA (Virtual European Solar and Planetary Access), which focused on adapting Virtual Obs…
Methane on Mars: New insights into the sensitivity of CH4 with the NOMAD/ExoMars spectrometer through its first in-flight calibration
Giuliano Liuzzi, Geronimo L. Villanueva, Michael J. Mumma +9
The Nadir and Occultation for MArs Discovery instrument (NOMAD), onboard the ExoMars Trace Gas Orbiter (TGO) spacecraft was conceived to observe Mars in solar occultation, nadir, a…
EnVision: understanding why our most Earth-like neighbour is so different
Richard Ghail, Colin Wilson, Thomas Widemann +9
This document is the EnVision Venus orbiter proposal, submitted in October 2016 in response to ESA's M5 call for Medium-size missions for its Science Programme, for launch in 2029.…
Multilayer modeling of the aureole photometry during the Venus transit: comparison between SDO/HMI and VEx/SOIR data
C. Pere, P. Tanga, Th. Widemann +4
The mesosphere of Venus is a critical range of altitudes in which complex temperature variability has been extensively studied by the space mission Venus Express (Vex) during its e…
