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.

What if a materials lab on Earth could screen a hundred alloys a day with little input from the scientist? Taylor and Andrew sit down with Joseph Krause, CEO and co-founder of Radical AI, to dig into what it takes to build a self-driving lab and why most of the field is still missing the hard part. From discovering that flagship SEM and XRD instruments ship with no real data access (and rebuilding their entire OS around the workaround), to MATRIX — their multimodal vision-language model that hones in on a target property in roughly 20 experiments — Joseph walks through the technical bets that got them here. He explains why they're using language-model embeddings to teach Bayesian optimization what "28% titanium" actually means, why "scientific intuition" has to be measured as a delta between human and AI annotations, and why Radical is going all the way to manufacturing instead of licensing compositions — because the real IP, and the only training data that matters, lives on the production floor.

Nominations for the Materials Today Rising Star awards are currently open and close on July 31st. If you know an early career researcher in the fields of materials science and engineering you think deserves recognition you can submit them here. [LINK}

What if you could know which batteries are worth building before you actually build them? Taylor and Andrew sit down with Dr. Qichao Hu, founder of SES AI, to explore how artificial intelligence is reshaping battery discovery and his experience in the field. From his decision to ditch solid state electrolytes and double down on liquid, to building a suite of simulation tools that map molecules all the way up to full cell performance. Dr. Hu lays out how SES went from lithium metal battery startup to offering their hard-won design tools as a platform for the rest of the industry.
