Episode notes
First Portable Antiprotons Demonstrated Safely
- CERN transported 92 antiprotons in a Penning trap across their facility, proving antimatter can be moved safely for remote precision experiments.
- Even total annihilation of those particles would release ~10^-8 joules—negligible energy comparable to a mosquito in flight.
Watching Artemis II With Kids And Teaching Launch Basics
- Jay Novella described watching the Artemis II launch with his kids, standing by the TV and teaching them countdowns, CapCom beeps, and orbital mechanics.
- He emphasized human spaceflight's emotional impact and that Orion provides ~330 cubic feet habitable volume, like two minivans inside.
Toilet Failure And Fix On Artemis II Elicits Cheers
- During Artemis II, Christina Cook reported a toilet fan failure; Mission Control guided a fix and they celebrated when she reported 'the toilet is go for use.'
- The crew nicknamed their Orion capsule 'Integrity' and joked about 'donating fluid' with procedure guidance.
