Episode notes
Surreal Docking Moment On Arrival
- Christina Koch describes docking with the ISS as surreal becoming reality when she first saw the station floating and completed an automated rendezvous.
- She recalls trusting systems and trainers, opening the hatch to friends who would care for them and begin mission work immediately.
Every Minute Preplanned For Science
- Life on the ISS is scheduled in five-minute increments to coordinate complex science and ground teams.
- That precision covers experiments, maintenance, meals and two hours daily exercise as countermeasures to microgravity.
Use Expeditionary Behavior Skills Daily
- Practice expeditionary behavior skills: communicate openly, identify barriers, and balance leadership and followership to keep a small team effective.
- Christina credits this training with preventing human factors from undermining mission science.
