During our one hour program, Bruce talked about ISDC events in general, then the Toronto location for this year's conference and the conference location, the Hyatt Regency Toronto. ISDC is a multi-track conference with workshops and an excellent exhibit hall. For more information, registration, hotel bookings, visit the ISDC 2015 website, http://isdc2015.nss.org/wordpress. From time to time during our discussion, Bruce mentioned a separate event needing separate registration, The Space Innovation Business Summit (http://isdc2015.nss.org/wordpress/the-space-innovation-business-summit). Bruce also went over the list of the keynote speakers, all of which are listed on the ISDC 2015 website. In fact, I strongly suggest you open the website and follow along with us during our discussion about the event. Bruce also said there would be upwards of 300 students present from around the world as a result of the Space Settlement Contest. Bruce highlighted both India and Romania for their student participation in the contest and ISDC 2015. Listeners asked many conference questions including networking, Q&A sessions, and inquiring if there was both a propulsion track topic and a human factors track topic. Toward the end of our discussion we took a call from Doug regarding EML2, depots, fuel, Mars transportation, etc. If you are planning to attend, remember you need a passport to enter Canada. Reserve early for the hotel, the conference and your transportation. ISDC is a terrific event. If you attend, I want to hear from you about it on The Space Show.
