Venus In Situ Explorer 4 to be launched in 2024. Of the 12 proposals submitted and reviewed by NASA, three were associated with this theme: two lander proposals, Venus In situ Composition Investigations (VICI) and Venus In Situ Atmospheric and Geochemical Explorer (VISAGE); and the Venus Origins Explorer (VOX), an orbiter whose proponents claimed would achieve similar scientific outcomes. None of the three advanced to the final shortlist. Venus In Situ Explorer The Venus In Situ Explorer (VISE) has been a lander mission concept proposed since 2003 by the Planetary Science Decadal Survey as a space probe designed to answer fundamental scientific questions by
