SpaceX dokončila řadu úprav potřebných pro druhý testovací let Starship
12.9.2023, Karel Polívka, aktualita
První testovací let Starship proběhl v dubnu a skončil dálkově spuštěnou explozí. Na základě analýzy dat se pak prováděly úpravy, jejichž dokončení vyžadovala FAA, než bude moci dojít k druhému letu. Elon Musk teď oznámil, že nutné úpravy už byly dokončeny.
V návaznosti na první testovací let Starship v dubnu 2023 požadovala FAA (agentura ministerstva dopravy USA) dokončení řady úprav, které vzešly z interního vyšetřování a analýzy dat SpaceX, než bude možné uskutečnit druhý testovací let. Na jejich seznam se můžete podívat v následující tabulce, nebo na obrázky s jejich seznamem, jež v tomto tweetu zveřejnil Elon Musk.

Celkem jde o 63 položek, ale jen 57 z nich bylo podle FAA nutných dokončit před tím, než bude možné uskutečnit druhý testovací let Starship (zbývajících 6 bude možné realizovat později). To už bylo podle Elona Muska splněno a na startovací plošině tak už čeká další booster Super Heavy (1. stupeň) a Starship na jeho vrcholu (2. stupeň):

Kdy k druhému letu dojde zatím není známé, jelikož teď se čeká na reakci ze strany FAA. Vzhledem k tomu, jak rychle ale SpaceX postupuje, se dá očekávat, že jakmile dá FAA zelenou, proběhne druhý testovací let Starship velmi brzy během následujících dní, jakmile to bude počasí umožňovat.
