Which of these moons is smallest?
以下哪個衛(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。這只是我們從未見過的部分。中國計劃在今年晚些時候發(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.
但這是一個巨大的挑戰(zhàn)。沒有辦法和飛船溝通。月球的其余部分將會擋住地球的任何信號。
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,中國本周朝著解決這一問題邁出了一步。它發(fā)射了一顆具有獨特使命的衛(wèi)星。如果一切按計劃進行,它將在月球軌道上運行,就像一個中繼站,讓地球上的科學家能夠與月球遠端的宇宙飛船交流。
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那里。因此,盡管這是朝著實現(xiàn)目標邁出的一步,但該任務的項目經理表示,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.
中國國家航天局的一位官員表示,最終目標是在月球上建立一個由機器人控制的永久基地。
