Last week, the Santa Clara University Markkula Center for Applied Ethics hosted a panel to discuss Challenges Raised by Life in Space. Today on KQED’s radio show The Forum, host Michael Krasney interviews some of those panelists for a national audience. They discuss a range of topics from the value and moral standing of the diversity of potential life elsewhere in the universe, to the modification of extraterrestrial ecosystems to suit human needs, to possible forward contamination of other planets through exploration.
