Overview

The Space Weather Laboratory performs research and analysis of the physical processes underlying space weather. It conducts space-based, ground-based, theoretical, and modeling studies of the chain of events that triggers space-weather effects of interest to NASA, other U.S. government agencies, and the general public. Laboratory staff lead the development of space environment projects and missions, and provide project scientists for NASA flight missions with space weather applications. The Laboratory communicates NASA research results to the scientific community, various space weather interests, and the general public.
