He's also been a strong advocate of funding space focused organizations though an extension of the tax credits presently provided to the Canadian mining industry, as outlined in my June 20th, 2010 article "Mining as a Model for the Commercial Space Industry."
More recently, Chapman has been involved with the American Institute of Aeronautics and Astronautics (AIAA) San Fransisco chapter and presented at the February 8th, 2012 small payload tech talks on the topic of "Technology Opportunities Related to Mineral Exploration & Mine Operations on the Moon and Mars."
It's well worth checking out and a nice counterpoint to his earlier presentation on "Our Cosmic Journey: The Importance of Mineral Exploration, Discovery and Development" which was presented in October 2010 to the Royal Astronomical Society of Canada.
But it's also worth noting that Chapman makes his presentation from the perspective of a "mechanic, welder and mining engineer" who, over a period of decades, also managed to turn himself into one of the largest mineral land owners in British Columbia.
This reminds me just a little bit of other "crazy people" like another John Chapman (who they named the Canadian Space Agency headquarters after), or Albert Fia (who designed the first Black Brant rocket for Bristol Aerospace) or John Carmack (who founded Armadillo Aerospace) or Richard Branson (who owns Virgin Galactic) or Elon Musk (who founded Space Exploration Technologies) or even Guy Laliberté (the entrepreneur, philanthropist, poker player, space tourist and current CEO of Cirque du Soleil) who each used their time and efforts to help promote or build space focused business ventures.
We should be encouraging these activities. For example, here's a recent Laurentian University presentation covering much the same topic.
