3) EGU2022 ABSTRACT SUBMISSION OPEN | 3-8 April 2022 | Vienna, Austria and Gather Online hybrid format
a) Session PS4.1: Paving the Way to the Decade of Venus
Please consider submitting an abstract to session PS4.1: Paving the Way to the Decade of Venus
https://meetingorganizer.copernicus.org/EGU22/session/42854
Convener: Moa Persson; Co-convener: Thomas Widemann
Session scope: In June 2021, NASA and ESA selected a fleet of three international missions to planet Venus. 28 years since the Magellan orbital radar mapping mission, and 37 years since the last Venera/VeGa landing, Venus remains our enigmatic neighbour. Shrouded by its dense atmosphere, the surface is only studied from space at radar frequencies and in a limited number of near-infrared spectral windows. Many significant questions remain on the current state of Venus, suggesting major gaps in our understanding of how our nearest planet's evolutionary pathway diverged from Earth's. Did Venus ever have an ocean, how and when did greenhouse conditions develop, and to what degree do volcanic eruptions still affect the surface and atmosphere today? Comparing the interior, surface and atmosphere evolution of Earth and Venus is essential to understanding what processes have shaped our own planet. This is particularly relevant in a decade where we expect hundreds of Earth- & Venus-size exoplanets to be discovered. The session will address how these new missions will better understand Venus’ early evolution and past and present habitability.
Abstracts are due 12 Jan. 2022, 13:00 CET

4) Le spectrographe à haute-résolution HIRES pour l’ELT passe en phase B
HIRES est un instrument de deuxième génération de l’ELT. L’instrument est un spectrographe à haute-résolution (R = 100,000 et R = 150,000), avec aussi un mode IFU-SCAO. Il couvre le visible et le proche infra-rouge, exactement de 0.35 à 1.8 microns. Le design de phase A a laissé l’espace permettant une étude pour étendre vers la bande K.
HIRES est un instrument polyvalent qui peut apporter des résultats clefs pour la caractérisation des exoplanètes, pour la physique théorique, pour la cosmologie, pour la physique stellaire. C’est le seul instrument qui a la possibilité de répondre à deux ambitieuses questions qui ont motivé la construction de ce grand télescope : la détection de signatures de vie dans des exoplanètes semblables à la Terre, et la détection directe de la re-acceleration cosmique. Mais HIRES est un instrument qui couvre des intérêts scientifiques divers : transient extragalactiques, caractérisation des étoiles froides, étude des abondances du deutérium, recherche et caractérisation d’étoiles primitives, mesures des variations de la température du CMB, étude des disques protoplanétaires, recherche de trous noirs de petites masses, étude de la réionisation de l’univers,…
Ayant terminé avec succès la phase A en Mars 2018, le projet HIRES est maintenant soutenu par l’ESO pour ses travaux de phase B qui commenceront officiellement début 2022. Actuellement, 5 instituts français sont engagés dans le projet : l’IPAG (contact : Xavier Bonfils), LAGRANGE (contact : Andrea Chiavassa), l’IRAP (contact : Pascal Petit), le LUPM (contact : Julien Morin) et le LAM (contact : Isabelle Boisse, représentante française à l'executive board).

5) Survey about the DIVA+ database of High contrast Imaging, hosted in europe (Marseille-Grenoble DC service)
Dear Colleagues,
The goal of the DIVA database (https://cesam.lam.fr/diva/) is to distribute reduced high contrast imaging data from several published exoplanet surveys (VLT-SPHERE / Naco, HST, Keck, etc.).
We would like to upgrade DIVA (to DIVA+) in the coming year by including a growing number of exoplanet and disk direct imaging surveys in homogeneous format, and by offering dedicated tools (rich query access, V.O. access, orbital fitting, completeness analysis, combined with RVs, interferometry, etc.).
If you are interested by this kind of data, please fill the survey :
https://sondage.osupytheas.fr/index.php/497529
We have designed this poll for both users and non-users of high-contrast imaging instruments (observers, modelers and theoreticians).
Your answers to this survey will allow to improve our services and implement new
functionalities based on your real needs.
DIVA+ is a service of the SPHERE / CeSAM - Data Center. In case you already filled in June 2021, the survey about SPHERE-DC, please do consider this poll as a complementary effort (on the Database side).
Best Regards,
Hervé Le Coroller
on behalf of the LAM-CeSAM and SPHERE Data Center team.
6) NASA ROSES-21 Amendment 39: C.26 EnVision VenSAR Science Team | Proposal Due Date Jan 20, 2022
EnVision is a mission to Venus being developed under the European Space Agency's (ESA) Cosmic Vision program. NASA is contributing the Venus Synthetic Aperture Radar (VenSAR) to the mission through a project implemented at NASA's Jet Propulsion Laboratory (JPL). VenSAR will characterize structural and geomorphic evidence of multi-scale processes that shaped the geological history of Venus as well as characterize current volcanic, tectonic, and sedimentary activity. Up to 2 VenSAR Science Team (VeST) members are expected to be from institutions located in ESA member states with support from their own national institutions. Proposals from non-U.S. institutions will be reviewed to the same standards as proposals from U.S. institutions.
Proposers should have knowledge and experience in radar studies of Venus, including radiometry, altimetry and instrument calibration. In addition, the overall team will have the required experience to understand the synergistic, multidisciplinary potential of VenSAR observations when combined with those of the complete EnVision instrument payload.
Deadline for submission of proposals following notification of intent (NoI) is January 20, 2022
