Reddit 有個版面稱作AMA (ask me anything 問我任何事)，每天都會安排名人或有特殊際遇的人透過網路與網友進行問與答，讓人知道許多名星不為人知的一面，也能藉此了解一些特殊經歷的細節。這是太空人Chris Hadfield 的問答討論串
Chris Hadfield 自介文
我是指揮官Chris Hadfield, 待了太空站五個月，最近剛返回地球。自從於哈薩克著陸後，我到過俄羅斯，美國，加拿大，做了不少醫學測驗，說明會，見了不少人分享我的太空經歷，也辦了簽書會(最近我剛出了一本新書 (An astronaut’s Guide to Life on Earth太空人的地球導覽)。在三次太空之旅以及當了21年的太空人之後，我的生活是忙碌但有趣的，我會盡我所能將一切與大家分享，所以，reddit，問我任何事！
問題二連結
嗨Chris，你翻唱的那首Groud Control to Major Tom (地面中心呼叫指揮官湯姆) 讓我聽了不自覺的開心起來，也不知為啥。謝謝你！歌曲連結 ChrisHadfield回應
不客氣。你們知道為何那首歌會那麼紅嗎? 實在令人百思不解。
網友回應
我猜應該是「太空」的關係。
VASIMR等離子火箭這概念是1977年哥斯大黎加的太空人/科學家 Franklin Chang Diaz 所提出來的，三十多年來科學界不斷地開發研究，使這技術已達接近成熟階段，可以運用在往後的太空計劃中，可望大大提高人類的太空旅行速度達六倍之多。
VASIMR是Variable Specific Impulse Magnetoplasma Rocket的縮寫，意即「可變特定動力磁等離子火箭」，除了運用極為安定的氬氣為燃料之外，它最大的特點就是能運用存在於太空中的電磁波，將其轉換成光能推進的能量，相對地提高了火箭的哩程數。此外，氬氣加熱後不但能轉換成推進能量，還會在火箭周身形成磁場，讓火箭不受放射線腐蝕。
他是近來備受推祟的科學教育家，他的話常被截錄引用出現在熱門的論壇中，現任羅斯地球與太空中心海頓天象館館長；同時也是美國自然史博物館天文物理部的助理研究員。2006年起，他開始主持公共電視網上的科學教育節目《新星-今日科學》（NOVA ScienceNOW），2011年8月5日泰森宣布他承接原由卡爾·薩根主持的節目宇宙大探索（Cosmos: A Personal Voyage）的主持人，該節目於2014年開播後廣受歡迎。
奈爾．德葛拉司．泰森的名言：
科學最棒的是就是不論你喜不喜歡，它都是真的。The good thing about science is that it's true whether or not you believe in it.
問題都不是出在小孩，問題總是出在大人，是他們趕走了小孩的好奇心。他們為數眾多，他們有投票權，他們佔有資源，這就是為什麼我教育的重點放在大人身上。Kids are never the problem. They are born scientists. The problem is always the adults. They beat the curiosity out of the kids. They out-number kids. They vote. They wield resources. That's why my public focus is primarily adults.
我們花了小孩們出生後的第一年教他們走路說話，剩下的時間都叫他們閉嘴坐下，一定是哪裡出錯了。 We spend the first year of a child's life teaching it to walk and talk and the rest of its life to shut up and sit down. There's something wrong there.
不知道並不可恥，真正的問題出在刻意用不理性的思想還有造作的行為去填滿無知所遺留下來的空虛。 ... there is no shame in not knowing. The problem arises when irrational thought and attendant behavior fill the vacuum left by ignorance.
在你腸子底端幾公分的短短的區域裡，住著的細菌(約一千億)比歷史上出生過的人類還要多，但確有很多人不斷地說我們是世界的主宰。 Within one linear centimeter of your lower colon there lives and works more bacteria (about 100 billion) than all humans who have ever been born. Yet many people continue to assert that it is we who are in charge of the world.
很多人常常到老了都還沒發覺，當你想要尋求愛或生命的意義時，意謂著它們可能躲在樹後或藏在石頭底下。生命中擁有最大成功的人都有一個認知，他們在生命裡創造自己的愛，建立自己的價值，產生自己的動能。對我來說，我的動力來自兩個主要思想，今天比昨天更了解這世界，還有就是減輕他人的痛苦，你會訝異這能讓你走得路程有多遠。 The problem, often not discovered until late in life, is that when you look for things like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation.For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And along the way, lessen the suffering of others. You'd be surprised how far that gets you.
我們之間都有關聯。彼此之間生物上的關聯，跟地球間化學上的關聯，還有就是跟宇宙間原子上的關聯。 We are all connected; To each other, biologically. To the earth, chemically. To the rest of the universe atomically.
我很好奇為何我們總是花更多的時間祝賀他人的成功，較少的時間去鼓勵那些失敗的人。 Curious that we spend more time congratulating people who have succeeded than encouraging people who have not.

Consider again that pale blue dot we've been talking about
再看一眼這蒼白的小藍點
Imagine that you take a good long look at it.

Now take it a step further:

Imagine that everything was made just for a single shade of that species,
想像萬物僅是為了某種膚色的人所創造的
or gender,
或是某個性別
or ethnic or religious subdivision.
某個人種某個宗教團體

因此生命的價值還有這脆弱的星球
is then determined only by our own wisdom and courage.
全都繫在我們自己的智慧與勇氣
We are the custodians of life's meaning.

We long for a Parent to care for us,
我們渴望有父母的照料
to forgive us our errors,

But knowledge is preferable to ignorance.

to embrace the hard truth

than a reassuring fable.
忘掉那床邊故事吧
Modern science has been a voyage into the unknown,
現代科學不斷地駛向未知的領域
with a lesson in humility waiting at every stop.
每一個站點都教我們更加地謙卑
Our commonsense intuitions can be mistaken.
我們感觀上的直覺反應總有出錯的時候
Our preferences don't count.
而我們的喜好是微不足道的
We do not live in a privileged reference frame.
我們並非享有特權與殊勝的待遇
If we crave some cosmic purpose,
若真的渴望生命擁有一個宏觀遠大的意義
then let us find ourselves a worthy goal.
那就為我們自己立下個值得追尋的目標吧
then let us find ourselves a worthy goal.
As children we fear the dark. The unknown troubles us. Anything might be out there. Ironically, it's our fate to live in the dark. Head out from the Earth in any direction you choose and, after an initial flash of blue, you're surrounded by punctuated only here and there by the faint and distant stars. Even after we're grown, the darkness retains its power to frighten us. And so there are those who say we should not inquire too closely into who else might be living in that darkness. Better not to know, they say. There are 400 billion stars in the Milky Way galaxy, of this immnse multitude, could it be that our hum drum sun is the only one with an inhabited planet? Maybe. Maybe the origin of life or intelligence is exceedingly improbable. Or, maybe civilizations arise all the time, but wipe themselves out as soon as they are able. Or, here and there, peppered across space, maybe there are worlds, something like our own, on which other beings gaze up and wonder, as we do, about who else lives in the dark. Life is a comparative rarity, you can survey dozens of worlds and find that on only one of them does life arise and evolve and persist. If we humans ever go to those worlds then it will be because a nation, or a consortium of them believes it to be to its advantage, or to the advantage of the human species. In our time, we've crossed the solar system and sent four ships to the stars. But we continue to search for inhabitants. Life looks for life.
