The EnVision candidate mission to the ESA\u2019s Cosmic Vision Programme consists of a low-altitude orbiter to investigate geological and atmospheric processes. The gravity experiment aboard this mission aims to determine Venus\u2019 geophysical parameters to fully characterize its internal structure. By analyzing the radio-tracking data that will be acquired through daily operations over six Venusian days (four Earth\u2019s years), we will derive a highly accurate gravity field (spatial resolution better than ~170 km), allowing detection of lateral variations of the lithosphere and crust properties beneath most of the geological features. The expected 0.3% error on the Love number k2, 0.1\u00b0 error on the tidal phase lag and 1.4% error on the moment of inertia are fundamental to constrain the core size and state as well as the mantle viscosity.<\/jats:p>","DOI":"10.3390\/rs13091624","type":"journal-article","created":{"date-parts":[[2021,4,21]],"date-time":"2021-04-21T21:25:10Z","timestamp":1619040310000},"page":"1624","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Determination of Venus\u2019 Interior Structure with EnVision"],"prefix":"10.3390","volume":"13","author":[{"given":"Pascal","family":"Rosenblatt","sequence":"first","affiliation":[{"name":"Laboratoire de Plan\u00e9tologie et G\u00e9odynamique, UMR-CNRS6112, Universit\u00e9 de Nantes, 44300 Nantes, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8670-8410","authenticated-orcid":false,"given":"Caroline","family":"Dumoulin","sequence":"additional","affiliation":[{"name":"Laboratoire de Plan\u00e9tologie et G\u00e9odynamique, UMR-CNRS6112, Universit\u00e9 de Nantes, 44300 Nantes, France"}]},{"given":"Jean-Charles","family":"Marty","sequence":"additional","affiliation":[{"name":"CNES, Space Geodesy Office, 31401 Toulouse, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5584-492X","authenticated-orcid":false,"given":"Antonio","family":"Genova","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering, Sapienza University of Rome, 00184 Rome, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,21]]},"reference":[{"key":"ref_1","unstructured":"Ghail, R., Wilson, C.F., Widemann, T., Titov, D., Bruzzone, L., Helbert, J., Vandaele, A.-C., Marcq, E., Dumoulin, C., and Rosen-Blatt, P.
