Description
Falcon 9 Full Thrust: Densification and Barge Landings. Eric Berger describes how, following a 2015 failure, SpaceX developed the Falcon 9 Full Thrust, version 3.0/4.0. Driven by the Mars vision, they adopted densification—chilling liquid oxygen to boost density and increase payload efficiency by 10 to 12 percent. Crucially, they focused on landing the booster vertically on a moving barge, skipping steps in the reusability process. This challenge required redesigned Merlin engines and advanced avionics, leading to several learning failures as they tried to figure out how best to line up the rocket with the ship. Guest: Eric Berger.
