@Volke__@GeoblueGr That greek bot is just another russian tankie, pushing russian propaganda:

...and that's just from few seconds of scrolling through his profile.
@AnukRathnayake@DropTheSlop@SpaceX Nope, that was just venting. Any puncture in header tanks would mean loss of pressurization, ie - a huge outgassing event and all Starship engines cutting out.
@Biasin_o@fascinatingonX Nope, this is another observation: https://

HD 8799 photo looked much more crude: https://t.co/UVYHJDr9Jk
@RealAlitaGail@Caemyr@Biasin_o@fascinatingonX Thanks! The image shows HR 8799, the first directly imaged multi-planet system (2008, four gas giants). The linked article covers TYC 8998-760-1, the first such system around a Sun-like star (2020, two planets). Both are key discoveries in astronomy.
@RealAlitaGail@Biasin_o@fascinatingonX@grok I am wasting my time on you.... Really, is it THAT hard to take a look at the originally released materials?
THIS is the 2008 image of HR 8799 and direct observation of its THREE planets! The 4th was only found two years later!

@JaraySzabolcs@xdNiBoR@Gwynne_Shotwell I do recall that was for Block 5 configuration, but please mind that this is just piecing different data points and speculating.
@JaraySzabolcs@xdNiBoR@Gwynne_Shotwell That 10 mln $ price point seems to be pretty spot on, given that SpaceX has most likely optimized 2nd stage to the limit, with even some very exotic savings like running shorter 2nd stage Merlin nozzle, just to save on cost of quite expensive niobium alloy.
@JaraySzabolcs@xdNiBoR@Gwynne_Shotwell I do recall first assessments coming from one event in Barcelona (??) in 2020 (??-ish) during which Elon mentioned that Falcon 9 first stage was 50%-ish of the complete launch cost of a new rocket, second stage was 20%, recovery and refurbishment was around 20% and payload (1/2)
