Through the prism of the 8th Digital Earth Summit and within the context of the disastrous 2020, this article addresses some of the issues and challenges that need to be addressed in Digital Earth Vision 2030. Some significant scientific aspects of the Digital Earth development are described and briefly discussed: the problem of providing a satisfactory definition of the Digital Earth and typology of different geospatial visualizations, the ambiguity between the concepts of Digital Earth and Digital Twins, the problems arising from the use of Digital Earth in sustainable development as well as the problem of using Digital Earth for natural and technological disasters prevention and mitigation. Attention is given to the use of Digital Earth in exploring the key challenge of 2020 – the COVID-19 pandemic. The possibility of using the Digital Earth as a tool for fundamental research is declared.
