Why super-cooled fuel?
Anyone know what is the rationale for supercooled fuel? Obviously you get a higher density, so more energy packed in a given size of tank. But it adds complexity and trouble. Why not increase the diameter of the rocket instead? Is it because they already have a proven mechanical design and are "stretching" it to the limit, or is it because the extra aerodynamic drag caused by a larger diameter rocket would be a significant loss?
