“@nextspaceflight A third is under construction”

“@DJSnM @doug_ellison @dsfpspacefl1ght Under consideration. We’ve already stretched the upper stage once. Easiest part of the rocket to change. Fairing 2, flying soon, also has a slightly larger diameter. Could make fairing much longer if need be & will if BFR takes longer than expected.”

“@DavideDF_ @doug_ellison @dsfpspacefl1ght Side boosters landing on droneships & center expended is only ~10% performance penalty vs fully expended. Cost is only slightly higher than an expended F9, so around $95M.”

“@AngryPackOMeese @dlxinorbit @doug_ellison @dsfpspacefl1ght Of course :)”

“@AngryPackOMeese @dlxinorbit @doug_ellison @dsfpspacefl1ght Maybe that plan works out, but I will seriously eat my hat with a side of mustard if that rocket flies a national security spacecraft before 2023”

“@dlxinorbit @doug_ellison @dsfpspacefl1ght That was three years ago, before ULA cancelled all medium versions of Delta IV. Future missions have all Delta fixed costs piled on, so their cost is now $600M+ for missions contracted for launch after 2020. Nutty high.”

“@doug_ellison @dsfpspacefl1ght Both exhaust velocity (Isp) and mass ratio drive the rocket equation. Also thrust/mass matters a lot for Oberth effect. Delta upper stage Isp is good, but mass ratio and thrust are not.”

“@doug_ellison @dsfpspacefl1ght The performance numbers in this database are not accurate. In process of being fixed. Even if they were, a fully expendable Falcon Heavy, which far exceeds the performance of a Delta IV Heavy, is $150M, compared to over $400M for Delta IV Heavy.”

“Customs problem solved! https://t.co/6D0Fbm8NFI”

“Or maybe “Temperature Enhancement Device””

“Apparently, some customs agencies are saying they won’t allow shipment of anything called a “Flamethrower”. To solve this, we are renaming it “Not a Flamethrower”.”

“@TheTeslaShow Early access build and especially Dev build are feature-rich, but the features aren’t reliable enough yet”
