Yeah, only LOX is really super cooled. I think there were other silly mistakes in the webcast like them saying it will use multiple engines to land etc.


Falcon 9 v1.1:


LOX: ~ -180C

RP-1: ambient, ~ 21C


Falcon 9 Full Thrust:


LOX: -206C (~9.9% density increase versus v1.1)

RP-1: -6.6C (2.6% density increase v1.1)


Angara:


LOX: -180C

RP-1: -15C (density increase 3.4% vs ambient 21C)


So they could go even colder for RP-1 but not a whole lot of difference. LOX is where the big gains can be made and that is what they did.


Not official yet but there is a possibility for an attempt tomorrow.
