In 2018, the National Academies released Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space. The decadal survey identified key science questions and prioritized observational needs to advance U.S. efforts in Earth science and support critical applications such as climate modeling and weather prediction. In the past few years, the need for actionable data and better scientific information on Earth's interacting systems has increased in urgency, as global climate change accelerates coupled with increasing numbers of extreme weather events.

At the request of NASA, this mid-term assessment evaluates progress and recommends actions to meet decadal survey priorities. This report explores ways that NASA's Earth Science Division can maintain programmatic balance, improve alignment with decadal survey priorities, and prepare for the next decadal survey.
