Colonizing mars—An opportunity for reconsidering bioethical standards and obligations to future generations

The exploration and settlement of Mars provides a rare opportunity to reconsider our ethical, political, philosophical, and economic relationships with non-human life (very broadly defined) relatively free of many of the constraints that have framed and limited our analyses throughout our many histories. Manned and robotic exploration throughout and beyond our solar system also fosters reconsideration of our obligations to future generations and allows for expansion of membership in the class that constitutes those generations. This paper argues that the concept of “future generations” should not be limited to Homo sapiens, as currently defined. Opportunities for a higher ethical standard within the context of the discovery of extraterrestrial life are discussed in terms of a thought experiment and mechanisms to allow future generations to be represented in these ethical discussions are suggested.
