最新报道:According to Bijie.com and BlockBeats, on August 23rd, SpaceX CEO Elon Musk stated that building a fully reusable orbital rocket is one of humanity's most challenging engineering problems to date, even more challenging than landing on the moon, which is why it remains unsolved. He expressed cautious optimism that Starship will achieve full reusability next year. Another key technology, orbital refueling, is relatively simple and, with luck, could be realized next year. By then, human consciousness and life will be able to extend to other planets and even stars.
