Episode notes
ISS As Science Lab And Symbol
- The ISS is a continuously operating low‑Earth orbit laboratory that has flown for 25 years and inspires globally.
- John Horak frames it as both a scientific platform and an engineering monument to international cooperation.
Microgravity Reveals Hidden Physics
- The ISS lets researchers 'turn gravity down' to microgravity and reveal processes masked on Earth.
- John Horak calls that ability a unique experimental knob unavailable in any ground lab.
Pieces Met Only In Orbit
- John Horak plays archival audio of Zarya's Proton rocket liftoff to illustrate the station's piecemeal assembly.
- He highlights that station modules never met on the ground and were assembled in orbit over many launches.
