We (@NASAhistory, @Georgetown & @NJIT) are seeking paper proposals for our 2022 symposium, "The History of NASA and the Environment." We welcome papers exploring NASA’s interest in, responses to, exploration of, and impact upon environments on Earth and other planetary bodies.
10h
**CALL FOR PAPERS** NASA has always had our eyes on the sky, but our heart has never left Earth. As James Fletcher, said, "Virtually everything we do...helps in some practical way to improve the environment of our planet and helps us understand the forces that affect it."
