"20 to 30 years from first human landing if launch rate growth is exponential," the Tesla co-founder replied. "Assumes transferring ~100k each rendezvous and ~1M total people needed."
“如果发射率呈指数级增长，那么从人类首次登陆算起，需要20到30年，”这位特斯拉的联合创始人回答说。“假设每个集合点移民大约10万人，总共需要大约100万人。”

"Tesla is to protect life on Earth, SpaceX to extend life beyond," Musk said in a separate post.
“特斯拉是为了保护地球上的生命，SpaceX是为了将生命延伸到地球之外，”马斯克在另一篇帖子中说。

He has previously touted the idea of becoming a "multi-planet species," building a city on Mars and sending one million people to the red planet by 2050.
他此前曾鼓吹成为“多星球物种”的想法，即在火星上建立一座城市，并在2050年前将100万人送往这颗红色星球。

Earlier this year, he hinted that a crewed mission to Mars could happen as soon as 2029.
今年早些时候，他暗示载人火星任务最早可能在2029年实现。

"Humanity will reach Mars in your lifetime," he tweeted on July 6.

Images of Mars through robotic emissaries like the Perseverance rover shows a desolate, rocky, dusty and frigid landscape.
通过像“毅力”号探测器这样的机器人使者拍摄的火星图像显示了一个荒凉、多石、多尘和寒冷的景观。

Notably, efforts for NASA's Artemis program – which will eventually be crewed – have faced delays.
值得注意的是，美国国家航空航天局的阿特米斯计划(Artemis)计划——该计划最终将是载人的——已经面临延期。
