"We needed to set rocket technology on a path of rapid improvement. In the course of trying to put together Mars Oasis, I had talked to a number of people in the space industry and got a sense of who was technically astute and who wasn’t. So I put together a team, and over a series of Saturdays I had them do a feasibility study about building rockets more efficiently. It became clear that there wasn’t anything to prevent us from doing it. Rocket technology had not materially improved since the ’60s—arguably it had gone backward! We decided to reverse that trend."
