Speaking of Grant, he is also the educational outreach director for MarsDrive Consortium (MDC), and I have signed up to be a member of the team he is building to spread the word about Mars and space exploration in general. MDC is trying to help individuals and groups to pull together in the effort to become a spacefaring civilization. As the FAQ says
The MarsDrive Consortium (“MDC”) is a group engaged in bringing together like- minded individuals, groups and businesses for the purpose of raising the large scale public support and necessary resources for an actual human mission to Mars within the next 2 decades.I strongly support these goals and will do what I can to help, using Orbiter as one of the tools. To that end, I wrote a short piece on Orbiter for the MDC web site.
