The craft launched Tuesday is
Ładunkiem rakiety był satelita łącznościowy Intelsat 708, który podobno przetrwał katastrofę i został w pewnym stopniu odzyskany przez Chiny, co prawdopodobnie spowodowało wyciek zaawansowanych technologii do tego kraju.

Dziś wydarzyło sie coś ciekawego - Soyuz miał awaryjne wyłączenie silników na platformie. Nic sie nie stało ale to bardzo nietypowa sytuacja. Soyuz jest bardzo niezawodną rakietą i ostatni raz takie coś wydarzyło sie 18 lat temu. Nie wiadomo czy były jakieś uszkodzenia silników. Wstępnie powtórny start jest planowany na jutro.

Why? Because 1) that much carbon fiber costs a lot, and 2) they're big,
I think you guys really don't understand how much it cost to build aerospace structures in this size, these things are not made out of ebay carbon fiber, there are special carbon for aerospace that cost a lot more than your average carbon fiber, these have to be procured, stored in giant freezers, thawed, cut to size, layer up in up to hundreds of layers by hand with

1) ENGINE CLUSTER
Nine SpaceX Merlin 1D engines sit at the bottom of each of the craft's three cores, or boosters. The engines are identical to those on SpaceX's Falcon 9 rocket.
2) FIRST STAGE: THREE ROCKET CORES
Falcon Heavy's first stage consists of three cores. All three cores operate together at liftoff. About T+2:45
@factorys: W zasadzie to nie działa, bo jeszcze nie poleciała. Szczegół ale istotny...
Ruscy ów problem mieli z rakietą N-1 w latach 60.
N-1 miała w pierwszym stopniu ciut więcej silników niż Falcon Heavy (30 vs 27), ale wszystkie silniki były w jednym rdzeniu, a nie rozłożone na trzy. Orurowanie w jednym wielkim rdzeniu było więc bardziej skomplikowane.
Dodatkowo, silniki NK-15 też można uznać za... bardziej skomplikowane od amerykańskich Merlinów. Oczywiście nie jeśli chodzi o elektronikę, ale o rzecz podstawową: cykl spalania (wielostopniowe
