Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions
Earth and Space Science, Volume 13, Issue 6, June 2026.Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.
