The mysteries of space beyond Earth have captivated humanity since the first space exploration, and the imagination of extraterrestrial life on other planets. Space exploration has provided extremely valuable data for planetary scientists, allowing them to investigate the intrinsic nature of Solar System bodies, such as what other planets would look like, what their atmospheres are composed of, and whether there are any life forms. While past observations and in-situ measurements are extremely valuable, the results have raised essential questions. For example, why is the Earth the only planet with liquid water on its surface and life in the Solar System? What would the future be of the Earth? In recent decades, the discovery of exoplanets with a tremendously broad range of conditions around various central stars has created an exciting new avenue of research.

In this talk, I will introduce the effort led by the Institute for Basic Science (IBS) in Korea to understand Earth’s twin in our Solar System: Venus. IBS is preparing a long-term Venus monitoring project, the CLOVE project, which will acquire novel long-term data on reflectivity and its polarization from a series of low-Earth orbit CubeSats using four selected wavelengths. The first CLOVE CubeSat (CLOVESat-1) will be launched in 2026. CLOVESats will be operating together with ESA/EnVision, NASA/DAVINCI, and NASA/VERITAS. IBS has been in close communication with KASA (우주항공청) since 2025 regarding the future Venus exploration planning.
