@PaigeANjax -340 F in this case. Deep cryo increases density and amplifies rocket performance. First time anyone has gone this low for O2.187 retweets 588 likes -

@Robotbeat@elonmusk@lukealization may have to change seal materials at that point. Viton can go to -15F but it may be de-rated.0 retweets 2 likes -

@sgreen364@Robotbeat@elonmusk@lukealization I'm now convinced it has more to do with keeping the viscosity up.0 retweets 0 likes -

@Robotbeat@lars_0 it should be all about cost and reliability. Improving performance if it hurts the others two FOMs is counterproductive.1 retweet 0 likes - View other replies

@rocketrepreneur@Robotbeat@lars_0 But you also need enough performance to reliably pull off reusability, or it's for naught.1 retweet 0 likes - View other replies

@AscendingNode@Robotbeat They already had enough performance for reliable reusability.0 retweets 0 likes - Show more
