Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
A Stochastic Parameterization of Non-Orographic Gravity Waves Induced Mixing for Mars Planetary Climate Model
Jiandong Liu, Ehouarn Millour, François Forget +2
This paper presents a formalism of mixing induced by non-orographic gravity waves (GWs) to integrate with the stochastic GWs scheme in the Mars Planetary Climate Model. We derive t…
Increased hydrogen escape from Mars atmosphere during periods of high obliquity
Gabriella Gilli, Francisco González-Galindo, Jean-Yves Chaufray +10
It is still unknown how much water has escaped from Mars during its history. Hydrogen escape from Mars's atmosphere probably played a major role in drying the planet, but present-d…
Space Plasma Physics Science Opportunities for the Lunar Orbital Platform -Gateway
Iannis Dandouras, Matt G G T Taylor, Johan de Keyser +26
The Lunar Orbital Platform-Gateway (LOP-Gateway, or simply Gateway) is a crewed platform that will be assembled and operated in the vicinity of the Moon by NASA and international p…
Reflectivity of Venus' dayside disk during the 2020 observation campaign: outcomes and future perspectives
Yeon Joo Lee, Antonio García Muñoz, Atsushi Yamazaki +28
We performed a unique Venus observation campaign to measure the disk brightness of Venus over a broad range of wavelengths in August and September 2020. The primary goal of the cam…
The science case for POLLUX, a high-resolution UV spectropolarimeter onboard LUVOIR
Jean-Claude Bouret, Coralie Neiner, Ana I. Gómez de Castro +9
POLLUX is a high-resolution, UV spectropolarimeter proposed for the 15-meter primary mirror option of LUVOIR. The instrument Phase 0 study is supported by the French Space Agency (…
On the orbital variability of Ganymede's atmosphere
Francois Leblanc, Apurva V. Oza, Ludivine Leclercq +5
Ganymede's atmosphere is produced by radiative interactions with its surface, sourced by the Sun and the Jovian plasma. The sputtered and thermally desorbed molecules are tracked i…
Dusk Over Dawn O Asymmetry in Europa's Near-Surface Atmosphere
Apurva V. Oza, Francois Leblanc, Robert E. Johnson +4
The evolution of Europa's water-product exosphere over its 85-hour day, based on current models, has not been shown to exhibit any diurnal asymmetries. Here we simulate Europa's ex…
Temporal Variability of Waves at the Proton Cyclotron Frequency Upstream from Mars: Implications for Mars Distant Hydrogen Exosphere
Cesar Bertucci, Norberto Romanelli, Jean-Yves Chaufray +6
We report on the temporal variability of the occurrence of waves at the local proton cyclotron frequency upstream from the Martian bow shock from Mars Global Surveyor observations…
Solar wind charge exchange X-ray emission from Mars Model and data comparison
Dimitra Koutroumpa, Ronan Modolo, Gerard Chanteur +3
Aims. We study the soft X-ray emission induced by charge exchange (CX) collisions between solar-wind, highly charged ions and neutral atoms of the Martian exosphere. Methods. A 3D…
