Why SpaceX Really Lands In The Ocean (Physics)

摘要
SpaceX has been landing their boosters on a small drone ship in the middle of the Atlantic ocean for many years now. But, aside from looking cool, why does SpaceX actually land in the ocean? After all, they have to transport the booster all the way back to the coast. If they simply landed at the launch site, they could save millions of dollars every single year in transport costs. Moreover, the ocean is not nearly as stable as land, thus increasing the chances of a failed landing. Despite this though, SpaceX continues to land its boosters in the ocean. The first reason that pops to mind is safety for people down below, and though this does play a role in the decision, the main reason SpaceX continues to land its boosters in the ocean is actually because of physics. This video explains the physics behind why SpaceX chooses to land its boosters in the ocean and the future of booster recoveries.
