[0x04] Making Life Multi-planeta

Launch Rate | 发射率

When you seriously consider the idea of establishing a self-sustaining base on Mars or the Moon or elsewhere, you ultimately need thousands of ships and tens of thousands of refilling operations. This means you need many launches per day. In terms of how many landings are occurring, you need to be looking at your watch, not your calendar.

当你认真考虑在火星、月球或者其他星球上建立自给自足的外星基地（self-sustaining base）时，你会发现最终需要数千艘飞船和上万次补给（refilling operations）。这意味着你每天都要发射很多艘火箭。说到这（in terms of），那么会有多少次着陆呢？我想你需要看表而非看日历了。（也就是说非常频繁）

So while SpaceX's launch rate is quite high by conventional standards, it is still a very small launch rate compared to what will
ultimately be needed.

虽然按照过去的标准（by conventional standards）SpaceX的发射率相当高了，但对于最终目标来说（compared to what will ultimately be needed）还差得很远。
