Science Friction BONUS | The Challenger Legacy: Q&A
Feb 25, 2026
They answer listener questions about the Challenger disaster, including how the shuttle’s solid rocket booster joints were re‑engineered. They compare shuttle, Saturn V and SLS tradeoffs and discuss commercial versus NASA safety incentives. They cover abort options, inspection limits, how Orion reaches the Moon, launch windows, environmental impacts of rockets, and what space travel actually feels like.

Episode notes
Feynman Demonstrated What Engineers Already Knew
- Richard Feynman's famous cold-water O-ring demo showed reduced pliability at low temperature but Thiokol engineers had already recognised O-ring concerns earlier.
- Feynman illustrated the effect; the engineers had identified the issue during shuttle development.
Few Viable Abort Options After Major Damage
- NASA had multiple abort modes like Abort To Orbit, Trans-Oceanic Abort Landing, and Return To Launch Site, but few good options exist for severe in-flight structural damage.
- Water ditching was judged almost certainly unsurvivable for the shuttle due to its design and high speed.
Spacewalk Inspection On Columbia Was Possible But Problematic
- Columbia missions lacked planned EVAs and full inspection tools, making a spacewalk possible but logistically difficult and ultimately of uncertain benefit.
- The report noted limited cameras, EVA gear and uncertain payoff even if damage was found.
