Episode 120: Thermal Protection Systems

We have all seen the heat of atmospheric reentry depicted a thousand times in movies and TV shows, but how do we actually protect spacecraft from that danger? Taylor and Andrew sit down with Nate Olson, an aerospace engineer at NASA's Johnson Space Center, to explore the history of thermal protection systems. Nate unpacks the science of surviving atmospheric entry from the simple blunt-body design that made reentry physically possible, to the ~300,000 honeycomb cells hand-caulked with Avcoat on Apollo. We also touch on modern events like the Artemis I heat-shield anomaly and where he believes the technology could be headed.
