CNN News: 月亮也有陰暗面 并不是壞事

Which of these moons is smallest?

以下哪個(gè)衛(wèi)星是最小的?

Earth’s moon, Saturn’s Titan, Jupiter’s Callisto, or Jupiter’s Ganymede?

地球的衛(wèi)星，土星的土衛(wèi)六，木星的木衛(wèi)四，還是木星的木衛(wèi)三?

Earth’s Moon is not the smallest in our solar system, but it is the smallest on this list, with a diameter of around 2,000 miles.

地球的月亮不是太陽(yáng)系中最小的，但是它是上述名單中最小的，直徑大約2000英里。

AZUZ: Of course, our moon has a dark side, that’s not a bad thing. It’s just the part we never see. And China is planning to send a spacecraft to it later this year.

當(dāng)然，我們的月亮也有陰暗面，這并不是壞事。這只是我們從未見(jiàn)過(guò)的部分。中國(guó)計(jì)劃在今年晚些時(shí)候發(fā)射一艘宇宙飛船。

There’s a big challenge to that, though. There’d be no way to communicate with the craft. The rest of the moon would be in the way, cutting off any signals from earth.

但這是一個(gè)巨大的挑戰(zhàn)。沒(méi)有辦法和飛船溝通。月球的其余部分將會(huì)擋住地球的任何信號(hào)。

So, China took a step toward addressing that this week. It launched a satellite that has a unique mission. It will hang out in the moon’s orbit, if all goes according to plan, and act like a relay station that would allow scientists on earth to communicate with the spacecraft on the far side of the moon.

因此，中國(guó)本周朝著解決這一問(wèn)題邁出了一步。它發(fā)射了一顆具有獨(dú)特使命的衛(wèi)星。如果一切按計(jì)劃進(jìn)行，它將在月球軌道上運(yùn)行，就像一個(gè)中繼站，讓地球上的科學(xué)家能夠與月球遠(yuǎn)端的宇宙飛船交流。

Of course, the satellite has to find its sweet spot first and then the actual lunar lander has to go there afterwards. So, while this is a step toward accomplishing the goal, the mission’s project manager says a number of challenges remain.

當(dāng)然，衛(wèi)星必須先找到它的最佳位置，然后真正的月球著陸器必須隨后到達(dá)那里。因此，盡管這是朝著實(shí)現(xiàn)目標(biāo)邁出的一步，但該任務(wù)的項(xiàng)目經(jīng)理表示，仍存在許多挑戰(zhàn)。

The ultimate aim, according to an official with the China National Space Administration, is to set up a permanent base on the moon that’s run by robots.

中國(guó)國(guó)家航天局的一位官員表示，最終目標(biāo)是在月球上建立一個(gè)由機(jī)器人控制的永久基地。
