About the NASA Disasters Program

The Disasters Applications area promotes the use of Earth observations to improve prediction of, preparation for, response to, and recovery from natural and technological disasters. Disaster applications and applied research on natural hazards support emergency preparedness leaders in developing mitigation approaches, such as early warning systems, and providing information and maps to disaster response and recovery teams.

This month on EO Kids, we're looking at the history of viewing Earth from space, from Explorer 1 to our modern constellations of satellites. In this issue, learn about how NASA began watching Earth's weather and how satellite imaging of hurricanes has evolved over 60 years. Plus, build your own liquid-fueled fizzy rocket with your own team of engineers.
