It's time for the space human exploration advocacy community to get its act together. A change in U.S. Presidents, as will happen this year, almost always leads to a change in American space policy and plans. Whoever is elected this year will set the policy the country will be living with on the 50th anniversary of Apollo 11: July 20, 2019. With that reality in mind, those of us who wish for mankind to make additional "giant leaps" can no longer afford the perpetual bickering amongst ourselves that has characterized the pro-space advocacy community since about the time Neil Armstrong walked on the Moon. It is time for those of us who desire to see humans expand throughout the solar system (and then beyond) to come together, compromise, and unite behind a plan to get us again started down that path. The situation is complicated further by the very vocal disagreement between the “private” versus “public” space development communities; another distraction we cannot afford.
