  • You know the moon, rightthe big space rock humans landed on for the first time 50 years ago?

    你知道月球吧,那顆人類在 50 年前登陸的大大顆外星石頭?

  • Well, astronauts left a lot of stuff behind there.


  • Stuff like used scientific equipment, clothing, food wrappers and, welltheir poop.

    像是用過的科學設備、衣物、食物包裝和 …… 他們的便便。

  • Across all 6 moon landings, Apollo astronauts left 96 bags of human waste on the moon.

    在六次月球登陸的過程,阿波羅太空人總共留了 96 袋人類排泄物在月球上。

  • We're talking poop.


  • Pee.


  • Vomit.


  • It was left behind to save weight for the return trip.


  • Stuffed in big trash baggies, like this one, dropped from Apollo 11.

    它們被裝在像這樣的垃圾袋裡,然後從阿波羅 11 號投下。

  • Inside those bags is a big, unanswered question — a scientific mystery that I want answered: Is there anything alive in that moon poop?


  • I know, I know, this sounds ridiculous.


  • But the answer might help us understand how life started on Earth.


  • And it can help us understand our potential to contaminate other worldslike Marswith our literal s***.

    它也能幫助我們得知,是否有用我們的便便「污染」其他世界 (比如火星) 的可能性?

  • And the answer, it's not too far away.


  • It's lying in wait, nearly 240,000 miles away, on the moon.

    它有待我們發掘,就處於近 39 萬公里之外的月球上。

  • Right here. Thosethis really isn't to scale.

    就在這。那些 —— 好啦這不是等比例模型。

  • What I'm saying is we gotta go back for that s***.


  • Human feces can be disgusting, sure. This is notthis is Play Doh.


  • But it's also teaming with life.


  • Around half of its mass is made up of bacteria, representing some of the 1,000-plus species of microbes that live in our guts.


  • With the moon landings, we took microbial life on Earth to the most extreme environment it has ever been in.


  • And we don't know if it can survive there.


  • In all the ways Earth is so hospitable to life, the moon is not.


  • It does not have a protective magnetic field to deflect the most powerful and damaging cosmic radiation.


  • It doesn't have an ozone layer to absorb the sun's ultraviolet rays.


  • It doesn't have an atmosphere.


  • And the moon is subjected to wild temperature swings over day and night.


  • A lot would have to go right for the microbes to still be alive thereor at least revivable from a dormant state.


  • But there are some scientists who want to go back and check, because there are two really fascinating things that we can learn from this poop.


  • The first has to do with a planet millions of miles away from the moon: Mars.

    第一件事和距離月球幾百萬公里的星球有關 —— 火星。

  • For decades, scientists have wondered if there's life on Marsand they're getting closer to figuring it out.


  • Mars has a thin atmosphere, evidence of flowing water, and a more hospitable environment than the moon.


  • If microbes can survive on the moon, they're even more likely to survive on Mars.


  • So what happens if humans go to Mars and leave their poop there and the microbes in it start to spread?


  • It will be hard to tell what life we find there is Martian and what life we brought with us if we accidentally contaminate the planet with our poop.


  • There's also a bigger question.


  • There's a hypothesis about how life started on Earth, that (it) didn't actually start on Earth at all.


  • That some asteroid or comet, containing some microbes, crashed-landed here and seeded life on the planet.


  • Finding living things in the moon poop could support that hypothesis, because if microbial life can survive on the moon, it can survive on an asteroid, too.


  • And if the hypothesis is true, it can mean life travels across the universe, jumping from planet-to-planet, from asteroid collisions.


  • Here's a wilder thought: Let's say an asteroid comes hurteling by, slams into the moon, and projects the Apollo mission moon poop into the deep reaches of space.


  • Could that seed life in the broader universe?


  • Maybe.


  • So how do we figure out the answer to these great mysteries?


  • Easy.


  • We go back.


  • That's gonna take a lot of work and research and diving into internet clickholes.


  • Bad security for anything you're doing, including a project to go back to the moon, can ruin everything.
