CNN News: 太空探索新任務(wù)

 
Today's edition of CNN 10 gets off the ground with four proposed space missions and they go well beyond the moon and Mars. I'm Carl Azuz at the CNN Center. Thank you for taking the time to watch our show. NASA, the National Aeronautics and Space Administration, has four ideas it's looking at as possible future missions. 
 
今天的CNN 10新聞從四個太空任務(wù)開始，遠(yuǎn)不止于月球和火星。我是卡爾·阿祖茲，這里是CNN中心。謝謝大家觀看我們的節(jié)目。美國國家航空航天局(NASA)對未來可能的任務(wù)有四個想法。

Two of them would focus on Venus. One of them would explore Jupiter's moon Io and one of them would fly by Neptune's moon Triton. I keep saying would because these are just ideas at this point. They'll each be researched by a team over a period of nine months and when the final proposals are made NASA will then decide whether to turn them into actual missions. 

其中兩顆會聚焦在金星上。其中一個將探索木星的衛(wèi)星木衛(wèi)一，另一個將飛越海王星的衛(wèi)星特里同。我一直說會，因為這只是一些想法。它們將由一個團隊花9個月的時間里進(jìn)行研究，當(dāng)最終方案確定后，NASA將決定是否將它們變成實際的任務(wù)。

So what would scientists hope to learn from all this? As far as Venus goes, one thing they're interested in is its atmosphere which is toxic another is the planet's surface which is hot enough to melt lead. Venus' scorching rocky landscape could be mapped. 

那么，科學(xué)家們希望從這一切中得到什么呢?至于金星，他們感興趣的一件事是它的大氣是有毒的，另一件事是它的表面溫度高到足以熔化鉛。金星灼熱的巖石地貌可以繪制成地圖。

Jupiter's moon Io is believed to be the most volcanically active place in our solar system so NASA would like to find out more about the eruptions that happen there. And Triton, a moon that orbits Neptune could also be mapped and studied to see if there are signs of an ocean beneath the moon's surface. 

木星的衛(wèi)星木衛(wèi)一被認(rèn)為是我們太陽系中火山活動最活躍的地方，所以美國宇航局想要進(jìn)一步了解那里發(fā)生的火山噴發(fā)。此外，圍繞海王星運行的衛(wèi)星Triton也可以被繪制成地圖并加以研究，以確定月球表面下是否有海洋的跡象。

None of these missions would involve astronauts. Robotic spacecraft would be doing the traveling and of course all of them would come at a cost. In fact, the teams that are assigned these subjects will each receive $3 million just to come up with their proposals. 
 
這些任務(wù)都不涉及宇航員。機器人宇宙飛船將進(jìn)行旅行，當(dāng)然所有的旅行都是有代價的。事實上，分配給這些任務(wù)的團隊每個人都將獲得300萬美元來實現(xiàn)他們的建議。

If any of those are approved for missions, space.com says each one would be limited to a price of $500 million but that doesn't include the costs of launching the spacecraft and supporting it while it's in space. And for reference, the Juno mission alone from developing the spacecraft to getting it off the ground to processing all of its information was more than $1 billion. NASA could choose to give two of these new missions the green light. 
 
space.com說，如果其中任何一項被批準(zhǔn)用于太空任務(wù)，每一項的價格將被限制在5億美元，但這還不包括發(fā)射航天器和在太空中支持航天器的費用。作為參考，僅僅朱諾號的任務(wù)，從開發(fā)宇宙飛船到讓它離開地面，再到處理所有信息，就花費了超過10億美元。NASA可以選擇批準(zhǔn)其中兩項新任務(wù)。
