Future Exploration of Venus: International Coordination and Collaborations

Résumé

The many scientific questions about Venus and its increasing relevance for understanding Earth are resulting in a growing interest in the further exploration of Venus. The Venus Exploration Analysis Group has compiled goals and objectives for understanding Venus with input from the global Venus community through workshops and meetings. These goals require a prolonged, and multiple mission strategy with a program for astrobiology exploration of Venus that will be valuable for habitable exoplanets also as VEXAG advocates. Due to the thick highly acidic cloud cover and the high temperatures and pressures at the surface, Venus requires a multi-pronged approach to scientific exploration with orbiters, atmospheric platforms, descent probes, and surface stations or landers. Even a large flagship class mission will be unable to obtain all the required observations. The recent discovery of phosphine in the atmosphere elevates the astrobiology interest in exploring Venus. To achieve a better understanding of Venus which may have been the first habitable planet will require a sustained effort. We suggest that challenges presented by the high cost of large missions and competition with other exploration targets can be overcome through international collaborations. Such collaborations can present challenges due to institutional or national policies in the allocation of budgets or resources and priorities. However, Cassini/Huygens was an exemplary collaboration between NASA and ESA for exploring Saturn and Titan; additionally two Mars collaboration are underway: ESA-Russia for TGO and NASA-ESA for Sample Return.[2]. Despite delays, the NASA-ESA collaboration for the exploration of the Jupiter system is now moving forward with launches of the JUICE and Europa Clipper missions later this decade. We expect that collaborations will continue and be valuable, if not essential, for advancing Venus science.
