The Artemis II mission hurtles towards re-entry and splashdown. The 13 Minutes crew run through the schedule that includes 28,864 mph, searing heat, 11 parachutes, and 3.9g forces. Long-time Nasa scientist Dr Phil Metzger talks about the issue of AVCOAT – the ablative coating that will shield the capsule’s flat underside. And we also talk about his work at Nasa’s “Swamp Works” where much was studied about building structures on the moon for a moonbase. Season 4 theme music by Hans Zimmer and Christian Lundberg and produced by Russell Emanuel, for Bleeding Fingers Music.
