The lava tube was discovered in 1913.

熔岩洞于1913年被发现。

These streams are coming from the ceiling of the lava tube and above us is the rainforest.

这些小溪是从熔岩的天花板上流下来的，我们头上的是雨林。

The findings suggest there could be hundreds of pits on the moon and thousands of lava tubes.

该研究结果表明，月球上可能有数百个月坑和数千个熔岩洞。

As the island gets bigger and bigger, right, there`s lava tubes, kind of, you know, build on each other.

随着岛屿越来越大，就会有层层叠叠的熔岩管道。

Researchers examined radar measurements by NASA's Lunar Reconnaissance Orbiter, and compared the results with lava tubes on Earth.

研究人员检查了美国航空航天局月球轨道勘测器的雷达测量结果，并将结果与地球上的熔岩洞进行了比较。

The pit, like the more than 200 others discovered there, was created by the collapse of a lava tube.

与那里发现的其他200多个月坑一样，这个月坑由熔岩洞塌陷而形成。

Lava tubes on Earth are usually up to 15 metres wide and can run for several kilometres.

地球上的熔岩管通常最宽可达 15 米，绵延数公里。

These roots are coming from the ceiling of the lava tube, and above is rainforest.

这些树根来自熔岩管的天花板，上面是热带雨林。

There are lava tubes as well, where the top of a lava flow cooled and formed a tunnel through which lava could flow for long distances.

还有熔岩管道井，岩浆流顶部冷却后形成一个通道，使得岩浆可以在里面长距离流动。

It's flowing quickly from Hawaii's Kilauea Volcano, raising through a lava tube and splashing into the Pacific.

它从夏威夷的基拉韦厄火山快速流动，通过熔岩管上升并溅入太平洋。

One interesting idea is to use lava tubes — underground caverns created by ancient lava flows, where the top of the flow cooled and created a roof.

一个有趣的想法是使用岩浆管道——由古代熔岩流在地下形成的洞穴，在那里的熔岩流冷却形成了一个屋顶。

Hard-shell or inflatable structures may not provide the radiation protection that we need, and living underground in lava tubes doesn't quite support direct surface exploration on the planet.

硬壳或充气结构可能无法提供我们所需的 防辐射保护层，住在地下的熔岩管道里不太利于我们对 星球表面的直接探索。

The wind can also carve out caves. You often see these in deserts. There are caves in lava tubes too.

风也可以开凿出洞穴。你经常在沙漠中看到这些。熔岩管中也有洞穴。

" One of the first big hurdles there is proving that they [the lava tubes] are structurally sound, " says Mr Martin.

“其中一个首要的大障碍是证明它们 [熔岩管] 在结构上是合理的， ”马丁先生说。

The best option, it concluded, would be to build the entrance where a wall of the lava tube had naturally collapsed open.

它得出的结论是，最好的选择是在熔岩管壁自然坍塌的地方建造入口。

Another issue is whether the lava tube's ceiling would be fully airtight, and if not, how to seal it to prevent leaks.

另一个问题是熔岩管的天花板是否完全密封，如果不是， 如何密封以防止泄漏。

The first step would likely involve robots and 3D printers constructing covered habitats from lunar soil, or building shelters inside caves formed by lava tubes from the moon’s volcanic past.

第一步可能涉及机器人和 3D 打印机用月球土壤建造有盖的栖息地，或者在月球火山过去的熔岩管形成的洞穴内建造避难所。

Rather than simply situating a Moon base inside a lava tube—domes and shiny buildings and all—they suggested that a section of such a tube could be pressurised with breathable air.

他们并没有简单地将月球基地放置在熔岩管内——圆顶和闪亮的建筑物等等——他们建议可以用可呼吸的空气对熔岩管的一部分进行加压。

First discovered during the Apollo programme, these lunar lava tubes are a legacy of when Earth's nearest celestial neighbour was geologically hyperactive, with streams of boiling basaltic magma bursting from the interior to flow across the Moon's surface as lava.

在阿波罗计划期间首次发现，这些月球熔岩管是地球最近的天体邻居在地质上过度活跃时留下的遗产，沸腾的玄武岩岩浆流从内部爆发， 以熔岩的形式流过月球表面。

To find out, he and Dr Benaroya built a computer model to simulate the integrity of a relatively small lava tube in the Moon's Oceanus Procellarum (Ocean of Storms), which was photographed by the Indian Chandrayaan-1 lunar probe 15 years ago.

为了找到答案， 他和 Benaroya 博士建立了一个计算机模型来模拟月球 Oceanus Procellarum（风暴之海）中相对较小的熔岩管的完整性，这是 15 年前由印度月船一号月球探测器拍摄的。
