NASA's Nuclear-Powered Mars Mission and Ngogo Chimps: What Space Propulsion and Intergroup Conflict Teach Us

In this Science Magazine podcast, Sarah Crespi guides listeners through two major stories: NASA’s plan, announced for 2028, to demonstrate nuclear-electric propulsion for a Mars mission using a fission reactor and helicopter-like Skyfall payloads to probe subsurface ice and potential landing sites; and Erin Sandow’s account of a decades-long division within the Ngogo chimpanzee population in Kibale National Park, Uganda, whose polarized groups engage in lethal intergroup aggression. The episode situates Artemis 2’s lunar flyby in the broader context of space exploration and competition. The discussions cover technical challenges, bureaucratic red tape, and the potential for social dynamics to illuminate human conflict and cooperation.

Overview

In this Science Magazine podcast, two major topics anchor the conversation: NASA’s nascent plan to launch a nuclear-powered Mars mission in 2028 and the Ngogo chimpanzee conflict observed over decades in Kibale National Park, Uganda. Freelance science journalist Hannah Richter explains that the mission would demonstrate nuclear-electric propulsion, a long-standing idea that could shorten travel times in the solar system and reduce fuel mass on board. Erin Sandow describes a striking intergroup polarization in a large chimpanzee community, where two neighboring groups shift from coexistence to lethal raids, offering a model to think about human conflict in new ways.

"It's essentially a 60 year dream that if this mission goes as planned, can come to fruition in only two years." - Hannah Richter
