SpaceX CEO Elon Musk on Sunday said that the importance of reusable rockets was crucial for humans to become a multiplanetary civilization amid the billionaire’s Mars colonization goals.
Cannot Become Multiplanetary Without Reusable Rockets
Responding to a post by Tesla Owners Silicon Valley, which shared that SpaceX had reduced costs per kg to orbit by 500x from approximately “$54,500 (Shuttle era) to ~$1,500.”
Musk said that the assessment of a technology lies in calculating how “it improves fundamental metrics,” adding that to achieve multiplanetary status without reusable rockets “is impossible.”
He then drew parallels to the colonial powers reaching America, saying that it would’ve been “impossible to colonize America with expendable boats.”
