4. Innovating for Power and Precision at Sea To increase rocket efficiency, Musk pushed for propellant densification, chilling liquid oxygen to nearly -300°F to fit 10-12% more mass on board. This segment also explores the "Falcon 9 full thrust" version, which was rebuilt for rapid reuse with upgraded avionics and landing legs. A major challenge involved landing boosters on moving barges in the ocean, an aerodynamic feat likened to nine Dixie cups falling from space. These innovations were essential for making spaceflight economically viable by refurbishing and flying rockets multiple times. (4)
