propellant densification

Lions were never crazy about basic inorganic chemistry, but propellant densification is the latest thing, like any improvement in rocketry, a major event only happening once in a lifetime. Like ion engines, it was something that spent most of our lives in science fiction, taken up & put away through the years. There's no record of it ever going beyond testing. SpaceX did yet another test, with plans to actually use it, someday.

At least the oxygen side will be refrigerated to 1 deg above the point at which it becomes a solid, providing a 7% increase in the amount of fluid mass in the same volume. Someday, maybe the kerosine side will be densified. It has the same effect as fitting a bigger rocket in a smaller space. It doesn't increase the efficiency or the thrust.
