Wondering how NASA science benefits your state? We’ve built an interactive dashboard where you can explore detailed economic impact reports for every U.S. state and the congressional districts they touch. NASA’s science investments reach all 50 states and 77% of congressional

Our next #AskAstrobio guest, Dr. Amber Young, uses climate and photochemical modeling to identify clear signs of life in Earth’s atmosphere—and applies that expertise to develop new strategies for detecting life on distant rocky planets. Join her live Q&A on June 17 at 1pm ET:
