[Elon Musk: Cautiously Optimistic About Starship Achieving Full Reusability Next Year] BlockBeats News, August 23, SpaceX CEO Elon Musk stated that building a fully reusable orbital rocket is one of the most challenging engineering problems humanity has ever faced, even harder than landing on the moon, which is why it has not yet been achieved. 'I am cautiously optimistic about Starship achieving full reusability next year. Another key technology is orbital refueling, which is relatively much simpler. If we’re lucky, it could also be realized next year. At that point, human consciousness and life could extend to other planets and even stars.' (Jin10)
