So the launch cost for that mission was 243 million dollars.

这次任务的发射成本是 2.43 亿美元。

And many analysts say that competition among commercial space travel companies brings launch costs down.

很多分析人士称，商业太空旅行公司之间的竞争降低了发射成本。

So SpaceX is aiming to have a launch cost for Starship on the order of a couple million dollars.

所以 SpaceX 的目标是让星际飞船的发射成本降至几百万美元。

Inflatable space stations are lighter than metal ones, and even small savings in weight make a big difference to launch costs.

充气式空间站比金属材质的空间站更轻，即使是减轻一点重量也会大大降低发射成本。

To launch even the cheapest rockets costs, you know, $10 million or $20 million.

即使是发射最便宜的火箭，也要花费 1000 万或 2000 万美元。

That said, if launch costs could come down and if inexpensive solar panels could utilize more of the Sun’s radiation, space-based solar panels may one day be financially plausible.

也就是说，如果发射成本能够降低，并且如果便宜的太阳能电池板能够利用更多的太阳辐射，天基太阳能电池板有一天可能在经济上是可行的。
