Land-cover change can have profound impacts on the Earth system. Unsustainable land use, driven by urban and agricultural expansion, not only causes important impacts on climate but also leads to ecosystem and environmental degradation.
Close to the end of its mission, the Dawn spacecraft performed high resolution observations of Occator crater at Ceres in order to study its bright points (faculae) at unprecedented detail. These observations establish Ceres as an ocean world.
Recent years have been an exciting time to unravel the mysteries of planetary interiors. A number of ongoing international space missions, ever evolving new technologies and numerical methods, and re-analysis of existing data are allowing us to gain new insights on the internal structures of planetary bodies.
