The Venus In Situ Explorer (VISE) has been a lander mission proposed since 2003 by the Planetary Science Decadal Survey as a space probe designed to answer fundamental scientific questions by landing and performing experiments on Venus.[1] It was a candidate for NASA's New Frontiers program Mission 4 to be launched in 2024. As of 2013 the Principal Investigators are refining and promoting the mission concept.[2] It may use a new atmospheric entry mechanism, a mechanically-deployed aerodynamic decelerator, known as the Adaptive Deployable Entry and Placement Technology (ADEPT).[2]


The study of Venus is essential to understanding the evolution of terrestrial planets, understanding how Venus and Earth diverged, and comprehending when and if planets develop habitable environments.[3] While on the surface, the Venus In Situ Explorer would function for several hours to acquire and characterize a core sample of the surface to study pristine rock samples not weathered by the very harsh surface conditions of the planet. Also, the VISE would determine the composition and mineralogy of the surface.[4][5] The lander would also release a short-lived balloon to measure cloud-level winds.[6]

The science payload would include cameras, spectrometers, a neutral mass spectrometer, a meteorology package, and other instruments to determine mineralogy and surface texture.[3]
