In Washington he has participated in debates on space policy, veterans’ issues, public safety and science-based decision making, bringing his technical and service background to legislative work.

Advocacy, writing and public roles

Kelly has co-founded and supported organizations focused on gun safety, public health and community recovery, particularly following the 2011 shooting that seriously injured his wife. He is also an author and public speaker, contributing essays and books on his life, spaceflight and civic engagement.
