“…The study of Venus-like exoplanets has become increasingly important given the announcement of several future in situ Venus missions like DAVINCI+ (Garvin et al 2022), VERITAS (Cascioli et al 2021), Venera-D (Vorontsov et al 2011;Zasova et al 2019), andEnVision (Widemann et al 2020). The data gathered from these missions will provide invaluable information about Venus, such as updates on the structure and composition of its atmosphere, determining its water-loss history, and compiling a high-resolution map of its surface.…”

Understanding the physical characteristics of Venus, including its atmosphere, interior, and its evolutionary pathway with respect to Earth, remains a vital component for terrestrial planet evolution models and the emergence and/or decline of planetary habitability. A statistical strategy for evaluating the evolutionary pathways of terrestrial planets lies in the atmospheric characterization of exoplanets, where the sample size provides sufficient means for determining required runaway greenhouse conditions. Observations of potential exo-Venuses can help confirm hypotheses about Venus’s past, as well as the occurrence rate of Venus-like planets in other systems. Additionally, the data from future Venus missions, such as DAVINCI, EnVision, and VERITAS, will provide valuable information regarding Venus, and the study of exo-Venuses will be complimentary to these missions. To facilitate studies of exo-Venus candidates, we provide a catalog of all confirmed terrestrial planets in the Venus zone, including transiting and nontransiting cases, and quantify their potential for follow-up observations. We examine the demographics of the exo-Venus population with relation to stellar and planetary properties, such as the planetary radius gap. We highlight specific high-priority exo-Venus targets for follow-up observations, including TOI-2285 b, LTT 1445 A c, TOI-1266 c, LHS 1140 c, and L98–59 d. We also discuss follow-up observations that may yield further insight into the Venus/Earth divergence in atmospheric properties.

“…ExoMars consists of two launches, the 2016 with Trace Gas Orbiter, and the entry and descent demonstrator, and the 2018 with a Rover, and a stationary long-living science platform. All proposals for a Venus mission, national, or with Russian involvement [Vorontsov et al, 2011;Wilson et al, 2012] are not being implemented so far. The lack of national space programs have not prevented from consolidation of efforts in the field of planetary atmospheres in Russia.…”

“…Venera-style landers use only thermal inertia and thermal insulation to keep a central electronics compartment cool, allowing operation times of only hours (see e.g. Venera-D mission, [38]). The principal science payload of a such a lander would include surface imagers and non-contact mineralogical sensors such as a Gamma spectrometer with Neutron activation, capable of measuring elemental abundances of U, Th, K, Si, Fe, Al, Ca, Mg, Mn, Cl [39], and/or Raman/LIBS [40].…”

Venus: key to understanding the evolution of terrestrial planets

In this paper, originally submitted in answer to ESA’s “Voyage 2050” call to shape the agency’s space science missions in the 2035–2050 timeframe, we emphasize the importance of a Venus exploration programme for the wider goal of understanding the diversity and evolution of habitable planets. Comparing the interior, surface, and atmosphere evolution of Earth, Mars, and Venus is essential to understanding what processes determined habitability of our own planet and Earth-like planets everywhere. This is particularly true in an era where we expect thousands, and then millions, of terrestrial exoplanets to be discovered. Earth and Mars have already dedicated exploration programmes, but our understanding of Venus, particularly of its geology and its history, lags behind. Multiple exploration vehicles will be needed to characterize Venus’ richly varied interior, surface, atmosphere and magnetosphere environments. Between now and 2050 we recommend that ESA launch at least two M-class missions to Venus (in order of priority): a geophysics-focussed orbiter (the currently proposed M5 EnVision orbiter – [1] – or equivalent); and an in situ atmospheric mission (such as the M3 EVE balloon mission – [2]). An in situ and orbital mission could be combined in a single L-class mission, as was argued in responses to the call for L2/L3 themes [3–5]. After these two missions, further priorities include a surface lander demonstrating the high-temperature technologies needed for extended surface missions; and/or a further orbiter with follow-up high-resolution surface radar imaging, and atmospheric and/or ionospheric investigations.
