Recently, SpaceX CEO Elon Musk shared important insights on the development process of reusable orbital rockets. He believes that developing a fully reusable orbital rocket is one of the most challenging problems in the history of human engineering, with difficulties even greater than that of the lunar landing program. This also explains why the technology has not yet been fully mastered.

Musk stated that he is cautiously optimistic about the Starship achieving full reusability next year. In addition, he mentioned another key technology - orbital refueling. Compared to reusable rockets, the implementation difficulty of orbital refueling technology is lower. Musk expects that if everything goes well, this technology is also likely to make breakthroughs next year.

It is worth noting that the breakthroughs in these two technologies will open a new chapter for humanity's exploration of space. Musk looks to the future, stating that once these technologies are realized, human consciousness and life could potentially extend to other planets, and even to distant star systems.

This vision not only reflects SpaceX's ambitions in the field of aerospace but also reveals the opportunities and challenges that future space exploration may face. With the continuous advancement of technology, humanity seems to be getting closer to realizing the dream of interstellar travel. However, to truly achieve this goal, many technical difficulties and challenges still need to be overcome.

Elon Musk's remarks have once again sparked public interest and discussion about space exploration. Whether it is fully reusable orbital rockets or orbital refueling technology, they will open the door to interstellar travel for humanity. We look forward to the realization of these groundbreaking technologies and the profound impact they will have on human civilization.
