CNN News: NASA計(jì)劃向太陽(yáng)發(fā)射首個(gè)航天器

Which of these places is believed to have the highest temperature?
你認(rèn)為以下這些地方哪里的溫度最高？
Is it the sun`s surface, the sun`s corona or atmosphere, Earth`s core, or Mercury`s surface?
太陽(yáng)表層？太陽(yáng)的日冕或者大氣層？地核？又或者是水星表層？
The sun`s atmosphere or corona is thought to be about 300 times hotter than its surface and no one knows why.
太陽(yáng)的大氣層或日冕比其表層溫度高出約300倍。沒(méi)有人知道原因。
But scientists are hoping to get some more information about the sun`s mysterious corona and the rest of the star. NASA is planning to send a spacecraft there on the first mission to fly into the sun`s atmosphere. The outermost part of it anyway.
但是科學(xué)家們希望能得到更多關(guān)于太陽(yáng)神秘的日冕以及太陽(yáng)其他地區(qū)的信息。美國(guó)國(guó)家航空航天局（NASA）計(jì)劃執(zhí)行首個(gè)向太陽(yáng)大氣層進(jìn)發(fā)的任務(wù)——向那里發(fā)射一艘宇宙飛船——盡管是其最外層。
The sun is 93 million miles away from the Earth, and the Parker solar probe is scheduled to orbit the star from a distance of more than 3 million miles. It`s not nearly as hot there as in the sun`s 3 million degree corona. But the spacecraft will still have to endure temperatures of 2,500 degrees, and to do that, it will have a coat of carbon solar shields measuring almost five inches thick.
太陽(yáng)離地球有9300萬(wàn)英里遠(yuǎn)，而帕克太陽(yáng)探測(cè)器計(jì)劃在距離太陽(yáng)300多萬(wàn)英里的地方繞其運(yùn)行。這里的熱度不像太陽(yáng)日冕層溫度達(dá)300萬(wàn)度那么熱。但該航天器仍需忍受2500度的高溫，而且要做到這一點(diǎn)，它需要一層將近5英寸厚的碳化太陽(yáng)能板做盾牌。
The mission costs $1.5 billion. It`s scheduled to launch in the summer of 2018. Scientists hope it will help them better understand solar wind, improve space weather forecasting and learn more about stars in general.
這項(xiàng)任務(wù)耗資15億美元，計(jì)劃于2018年夏季發(fā)射。科學(xué)家希望它能幫助他們更好地了解太陽(yáng)風(fēng)，提高太空氣象預(yù)測(cè)水平，并了解更多有關(guān)太陽(yáng)的信息。
Humans cannot go on the deep space mission. It`s scheduled to last seven years. The spacecraft probably won`t come back to Earth. An expert say it would cost a lot more to send a person into deep space and keep him or her alive in the process than it does to send a spacecraft or even a robot.
人類不能介入執(zhí)行深空探測(cè)任務(wù)。這項(xiàng)計(jì)劃預(yù)計(jì)持續(xù)7年。而且這艘宇宙飛船有可能不會(huì)返回地球。一位專家表示，把一個(gè)人送去深太空并保證他或她在這一過(guò)程中能夠存活，比發(fā)射一個(gè)航天器甚至一個(gè)機(jī)器人耗資要多得多。
