人类能殖民月球吗?

Will We Ever Be Able to Colonize the Moon?

谈到太空殖民
When it comes to space colonization,
火星是现代太空探索的首选
Mars is at the forefront of modern exploration.
但同时 离我们最近的邻居——月球似乎被忽视了
Meanwhile, our nearest celestial neighbor – the Moon – is seemingly overlooked.
这一定程度上是
And that’s, in part,
因为月球不算是一个人类宜居地
because the Moon isn’t exactly a haven for humanity.
月球表面满布死火山
The lunar surface is covered with dead volcanoes,
巨大的陨石坑和可能有毒的灰尘
massive craters and potentially poisonous dust.
而且因为它的外大气层非常稀薄
It’s also constantly bombarded by space rocks raining down on its surface.
月面会持续遭受陨石雨的轰炸
due to its very thin and weak atmosphere known as an exosphere.
最重要的是 这一层极其薄的气体
On top of that, this ultra thin layer of gases
不能提供任何保护以阻挡太阳辐射
doesn’t provide any protection from the sun’s radiation.
但是一些科学家相信并非总是如此
But some scientists believe this wasn’t always the case.
最近美航天局的
Recent NASA findings show
研究表明月球可能曾有过明显的大气层
that there might have been a time when the Moon had a prominent atmosphere,
这使得月球成为外星殖民的有力竞争者
and it could make the Moon a stronger contender for colonization.
人们普遍认为
Billions of years ago,
内太阳系在数十亿年前形成之后
after the formation of the inner solar system, it’s believed that
年轻的行星以及月球受到了
the young planets and the moon were pummeled
太空岩石和行星残余材料的反复撞击
by space rocks and other leftover planet-building material.
该阶段称为后期重轰炸期或LBH
The period known as the Late Heavy Bombardment
人们认为它持续了有数百万年
or LBH, is thought to have lasted millions of years,
这一狂风暴雨时期的撞击痕迹表现为
and damage from this violent period was seen in craters
一些内行星和月球表面的陨石坑
on some of the inner planets and the Moon.
此外 这一时期也触发了一系列的火山喷发
There, the LBH triggered a series of volcanic eruptions.
导致岩浆填满了月球的陨石坑
Lava filled the lunar craters, creating seas that
形成了蔓延月面数百公里的岩浆海洋
stretched for hundreds of kilometers across its surface.
人们认为 在这一时期
During this period, it’s thought that
月球岩浆释放了一些气体或挥发物质
the lunar lava emitted gas components or volatiles
如一氧化碳 硫 氢气和氧气
like carbon monoxide, sulfur, hydrogen andoxygen.
在岩浆蔓的同时
As the lava spread,
这些挥发物质积聚形成了短暂的大气
the volatiles accumulated and formed a transient atmosphere.
人们相信 这一古老的大气层
The ancient atmosphere was believed to
比如今地球的大气层要薄得多
be much thinner than Earth’s current atmosphere,
但却是如今火星大气层厚度的1.5倍
but 1.5 times thicker than Mars’ current atmosphere.
火山喷发持续了约七千万年
The eruptions lasted for about 70 million years,
据估计 在这一时期
and it’s estimated that trillions of
释放的水有几万亿加仑的水
gallons of water was released during this period.
随着大气开始变薄
As the atmosphere started to thin out,
这些挥发物质要么流失在太空中
the volatiles were either lost to space or became
要么成为月面的一部分
part of the surface of the Moon.
研究人员相信
Researchers believe it’s possible that
大量的水可能已经流向了月极
a significant amount of water may have made its way to the lunar poles
并且被永久封冻在月球背面
and could be trapped in permanently shadowed regions.
实际上 美国航天局最新的分析
In fact, NASA’s new analysis
根据阿波罗计划所采集的样本
quantifies a source of volatiles based on
定量研究了那些挥发物质的一个来源
lunar samples collected during the Apollo missions.
而这些挥发物质能够为长期的
And these volatiles could provide key resources –
月球计划和其他任务
like water, air and fuel
提供一些关键的资源 如水 空气和燃料
– for extended moon missions and beyond.
因此 虽然火星仍是太空殖民地的首选
So while Mars is still a frontrunner when it comes to colonization,
但对月球历史及其储水能力的研究进展
revelations about the Moon’s past and its potential presence of water
不断证明 在我们放弃月球之前
continue to prove that there is still a lot more lunar exploration
月球还有很多需要探索的地方
needed before we count the Moon out.
