Looking ahead to 2017, it promises to be a busy year for space exploration and development.
The dialogue has shifted from "Should we expand outward into the solar system?" to "How are we going to do it?"
There is also the question of how exploring and developing the solar system will benefit our home planet and the people who choose to remain inhabitants of it.
This is why the Overview Effect is so important. In all of my interviews with astronauts, none of them said we should explore outer space because we needed to abandon the Earth. Rather, all of them seemed to have a renewed concern for the planet and for preserving it.
For this reason, I believe that the question before us is not even "How are we going to do it?" but "How are we going to do it right?"
More on this topic later.
