Robert Zubrin
Robert Zubrin (; born April 9, 1952) is an American aerospace engineer, author, and advocate for human exploration of Mars. He is also an advocate for U.S. space superiority, writing that "in the 21st century, victory on land, sea or in the air will go to the power that controls space" and that "if we desire peace on Earth, we need to prepare for war in space." He and his colleague at Martin Marietta, David Baker, were the driving force behind Mars Direct, a proposal in a 1990 research paper intended to produce significant reductions in the cost and complexity of such a mission.
