In this second of two episodes from the 2026 NASA Innovative Advanced Concepts (NIAC) Symposium at Wichita State University, Sarah Al-Ahmed talks with researchers developing the propulsion and life support technologies that could open up new frontiers in deep space exploration.

First, Artur Davoyan, associate professor at the University of California, Los Angeles, discusses Coilable Stacked Solar Sails, a new sail architecture that could enable fast missions to the outer planets and interstellar space. Then, James Bickford of Charles Stark Draper Laboratory introduces TFINER, the Thin Film Isotope Nuclear Engine Rocket, a project that generates thrust from the natural decay of radioactive thin films, enabling rendezvous with interstellar objects and missions to the solar gravitational focus. Finally, Alvaro Romero-Calvo, assistant professor at Georgia Tech, and Theo St. Francis, graduate researcher in Georgia Tech's Low-Gravity Science and Technology Lab, discuss their concept, Breathing Beyond Earth, a pump-free oxygen production system for long-duration space missions to Mars. Plus, Bruce Betts, chief scientist of the Planetary Society, joins Sarah for What's Up, with a look ahead to the launch of JAXA's Martian Moons Exploration mission, MMX.
