Bruce had a long standing interest in planetary exploration and the planning of future missions. His many detailed analyzes of future mission planning at Space Daily reawakened my own interest. When I began this blog, I had hoped that Bruce would be a regular contributor, and he contributed as his health permitted.
Bruce was enthusiastic and committed to seeing planetary exploration continue. He frequently held strong opinions on what the right course would be, and I often learned more from his defense of those explanations than I did from simply reading the factual descriptions of the options.
I never met Bruce, but I came to look forward to his articles and e-mails. His contributions will be missed.
Bruce loved to write about planetary exploration. I can think of no better tribute than to provide links to the major posts he contributed to this blog. You can find many more of his articles at SpaceDaily.
