SpaceX: Elon Musk tem bons motivos para usar motores menores em seus foguetes

Ryan Whitwam:
He (Musk) describes the advantage to this design in computer terms. In the past, mainframe systems would serve many clients, but everyone was out of luck if that single mainframe went down. Today, the services we use online are powered by many smaller computers, so a given service remains operational even if some individual computers fail. It’s the same with the Falcon Heavy. The rocket can compensate for a few engine failures — it can even reach orbit with as many as six dead engines. SpaceX plans to continue using large numbers of small engines in its rockets. The company’s next generation Big Falcon Rocket (BFR) will sport 31 engines.
Nos próximos 2-3 anos veremos um teste completo do BFR semelhante ao que foi feito com o Falcon Heavy no último dia 6/2. Esta próxima geração é destinada a desafios maiores como voos cislunares (espaço entre a Terra e a Lua) e pelo deep space com destino à Marte. O BFR pode ser o primeiro dos foguetes da SpaceX certificado para transporte de humanos.
