"The White House is providing fresh details of a major satellite program that administration officials call poised to reveal vital information about climate change and extreme weather events.

Why it matters: Known as the "Earth System Observatory," the program consists of at least five satellites to be launched through 2029 that will enhance, or in some cases revolutionize, the capabilities of the space agency's existing fleet of Earth-observing satellites.

Details: In an interview with Axios on Monday, NASA Administrator Bill Nelson said the upcoming satellite constellation will look at everything from aerosols — tiny particles in the atmosphere that are a major source of uncertainty in climate models — to sea level rise."
