NASA小行星樣本含碳和水 可助了解地球生命如何孕育
NASA's 1st asteroid sample is rich in carbon and water, OSIRIS-REx team finds
OSIRIS-REx 團隊發(fā)現(xiàn) NASA 的第一個小行星樣本富含碳和水
The initial glimpses of the off-Earth material are very promising.
對地外物質(zhì)的初步觀察是非常有希望的。
It looks like Bennu was indeed the right target for NASA's first-ever asteroid sample-return mission.
看起來貝努確實是美國宇航局首次小行星樣本返回任務(wù)的正確目標。
That mission,?OSIRIS-REx, delivered pieces of the 1,650-foot-wide (500 meters) Bennu to Earth?late last month. NASA gave the world its first look at the sample today (Oct. 11) during a live webcast event, which also provided a rundown of the first analyses performed on the off-Earth material.
上個月末,OSIRIS-REx 任務(wù)將 1,650 英尺寬(500 米)的 Bennu 碎片運送到地球。 NASA 在今天(10 月 11 日)的一次網(wǎng)絡(luò)直播活動中向全世界首次展示了該樣本,同時還提供了對地外材料進行的首次分析的概要。
Those very early scientific returns are promising, showing that Bennu is rich in both water and carbon-containing compounds, mission team members said.
任務(wù)小組成員說,這些早期的科學回報是有希望的,表明貝努富含水和含碳化合物。
"The OSIRIS-REx sample is the biggest carbon-rich?asteroid?sample ever delivered to Earth and will help scientists investigate the origins of life on our own planet for generations to come," NASA Administrator Bill Nelson?said in a statement today.?
NASA 局長 Bill Nelson 在今天的一份聲明中表示:“OSIRIS-REx 樣本是迄今為止運送到地球的最大的富碳小行星樣本,將幫助科學家們研究我們星球上的生命起源,為子孫后代提供幫助?!?/p>
"Almost everything we do at NASA seeks to answer questions about who we are and where we come from," Nelson added. "NASA missions like OSIRIS-REx will improve our understanding of asteroids that could threaten Earth while giving us a glimpse into what lies beyond. The sample has made it back to Earth, but there is still so much science to come — science like we've never seen before."?
“我們在 NASA 所做的幾乎所有事情都是為了回答有關(guān)我們是誰以及我們來自哪里的問題,”尼爾森補充道。 “像奧西里斯-雷克斯這樣的美國宇航局任務(wù)將提高我們對可能威脅地球的小行星的了解,同時讓我們一睹小行星之外的情況。樣本已經(jīng)返回地球,但仍有很多科學成果——像我們一樣的科學”以前從未見過?!?/p>
