Abstract The dual spacecraft mission BepiColombo is the first joint between European Space Agency (ESA) and Japanese Aerospace Exploration (JAXA) to explore planet Mercury. was launched from Kourou (French Guiana) on October 20th, 2018, in its packed configuration including two spacecraft, a transfer module, sunshield. cruise trajectory long journey into inner heliosphere, it includes one flyby of Earth (in April 2020), Venus 2020 August 2021), six Mercury (starting before orbit insertion...
Titan's polar surface is dotted with hundreds of lacustrine depressions. Based on the hypothesis that they are karstic in origin, we aim at determining efficiency dissolution as a landshaping process Titan, comparative planetology perspective Earth reference. Our approach based calculation solutional denudation rates and allow inference formation timescales for topographic depressions developed by chemical erosion both planetary bodies. The model depends solubility solids liquids, density...
Abstract BepiColombo has a larger and in many ways more capable suite of instruments relevant for determination the topographic, physical, chemical mineralogical properties Mercury’s surface than carried by NASA’s MESSENGER spacecraft. Moreover, BepiColombo’s data rate is substantially higher. This equips it to confirm, elaborate upon, go beyond MESSENGER’s remarkable achievements. Furthermore, geometry orbital science campaign, beginning 2026, will enable make uniformly resolved...
Abstract Thanks to the Cassini–Huygens mission, Titan, pale orange dot of Pioneer and Voyager encounters, has been revealed be a dynamic, hydrologically shaped, organic-rich ocean world offering unparalleled opportunities explore prebiotic chemistry. And while revolutionized our understanding each three “layers” Titan—the atmosphere, surface, interior—we are only beginning hypothesize how these realms interact. In this paper, we summarize current state Titan knowledge discuss future...
ABSTRACT Titan’s atmosphere is opaque in the near-infrared due to gaseous absorptions, mainly by methane, and scattering aerosols, except a few “transparency windows.” Thus, composition of surface remains difficult access from space still poorly constrained. Photochemical models suggest that most organic compounds formed are heavy enough condense build up at liquid solid states over geological timescales. Acetylene (C 2 H ) net production predicted be larger than any other compound C has...
Abstract In 13 years, infrared observations from the Visual and Infrared Mapping Spectrometer onboard Cassini provided significant hints about spectral geological diversity of Titan's surface. The analysis (IR) signature units enables constraining surface composition, which is crucial for understanding possible interactions between interior, surface, atmosphere. Here we investigate a selection areas in equatorial regions, imaged by Cassini's instruments, exhibit an apparent transition...
Purpose of the study: Work addiction risk is a growing public health concern with potential deleterious health-related outcomes. Perception work (job demands and job control) may play major role in provoking employees. We aimed to explore link between outcomes using framework job-demand-control model. Methods: Data were collected from 187 out 1580 (11.8%) French workers who agreed participate cross-sectional study WittyFit software online platform. The self-administered questionnaires Job...
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission explore one the most exciting bodies in Solar System, Saturn largest moon Titan. Titan, a "world with two oceans", is organic-rich body interior-surface-atmosphere interactions that are comparable complexity Earth. Titan also few places System habitability potential. remarkable nature was only partly revealed by Cassini-Huygens and still holds mysteries requiring complete exploration using...
Background Psychosocial well-being, which assesses emotional, psychological, social, and collective could help measure risk duration of sick leave in workers. Objective This study aims to build a structural equation model psychosocial well-being index based on 10 factors investigate its association with leave. Methods Data workers using Wittyfit was collected 2018. (job satisfaction, atmosphere, recognition, work-life balance, meaning, work organization, values, workload, autonomy, stress)...

The ESA Planetary Science Archive (PSA) hosted at the European Space Astronomy Centre (ESA/ESAC) is a multi-mission archive currently supporting ten planetary missions, from missions beyond their post-operations phase to being operated. data are archived following NASA Data System (PDS) Standard (version 3 or 4, depending on mission). Missions in operations within cruise phase, such as ExoMars Trace Gas Orbiter (TGO), BepiColombo, and JUICE, PDS4 format follow concept of operational...
Abstract During the first flyby of BepiColombo composite spacecraft at Mercury in October 2021 ion spectrometers observed two intense spectral lines with energies between 10 and 70 eV. The persisted also larger distances from were again lower intensity during cruise phase March 2022 second third as a single band. composition indicates that water is dominant gas source. outgassing causes to charge up negative potential −50 V. distribution energy signal depends on low electron fluxes around...
Objectives Work-related stress is a major concern. One of the best performing models Job Content Questionnaire (JCQ) Karasek, assessing job demand and control using 18 items. However, JCQ long complex. Visual Analogue Scales (VASs) are easy to use quick implement. VASs have been validated assess pain occupational stress; however, not evaluated. Therefore, we aimed validate VAS compared with items JCQ. Design We implemented cross-sectional observational study, by administering self-reported...
Morbidity before retirement has a huge cost, burdening both public health and workplace finances. Multiple factors increase morbidity such as stress at work, sedentary behavior or low physical activity, poor nutrition practices. Nowadays, the digital world offers infinite opportunities to interact with workers. The WittyFit software was designed understand holistic issues of workers by promoting individualized changes workplace.
The James Webb Space Telescope (JWST), scheduled for launch in 2018, is the successor to Hubble (HST) but with a significantly larger aperture (6.5 m) and advanced instrumentation focusing on infrared science (0.6–28.0 μm). In this paper, we examine potential scientific investigation of Titan using JWST, primarily three four instruments: NIRSpec, NIRCam, MIRI, noting that NIRISS will be complementary. Five core themes are identified: (1) surface (2) tropospheric clouds (3) gases (4)...
Abstract Explosive volcanism on the surface of planet Mercury is visible through pyroclastic deposits that surround morphologic features often identified as vent. Those are known faculae. The understanding explosive provides important information Mercury's geological, thermal, and volcanic history. Observations by MESSENGER spacecraft used to analyze in detail spectral properties 14 selected faculae with aim their chemical physical properties. Scientific observations obtained MASCS...
