ANALYSIS | Why the rocket fuel that will power Artemis II is so hard to handle | CBC Radio
It's difficult to imagine a substance that is hundreds of degrees below freezing yet still a liquid. Such is the strange nature of the liquid hydrogen and liquid oxygen that are the components of rocket fuel.

How touch is totally different in different places because of scale. Kinda cool. The nature of contact is not just what we think it is.

We believe this is the final nail in the coffin of the proton radius puzzle."

It's crazy that this image looks so 'still' but in reality, the object on the left is essentially falling faster and faster into the blue world on the right. So fast that it will be going 39,688.37 km/hr when it enters the atmosphere and we all hope and pray that the engineering was sound and everything goes well.
