DENSIFICATION AND THE CRUSHED SODA CAN Colleague Eric Berger. Berger explains the technical leaps required for the "Falcon 9 Full Thrust," specifically the use of densified propellants. By super-chilling liquid oxygen to nearly -300°F, SpaceX increased propellant density by 10-12%, drastically improving payload capacity. This innovation accompanied the challenge of landing boosters on ocean barges. Berger compares the fragility of an unpressurized rocket stage to a soda can, noting how easily they were crushed or exploded during early attempts to land on moving drone ships. These upgrades, including the "Octaweb" engine arrangement, were essential for creating a reusable fleet capable of frequent flight. NUMBER 4
