Humanity is preparing to move beyond low Earth orbit for the first time in
decades, and it won't be a quick visit this time. Long-term lunar habitation
is on the agenda, and the European Space Agency (ESA) is looking for ways to
build what we need on the Moon without dragging ton after ton of materials up
there. Its investigations have resulted in a quirky little experiment. Using
a bit of ultra-rare meteorite dust, the ESA worked with Lego to create a set
of "space bricks."
人类正准备几十年来首次飞出近地轨道，这次的访问不会很快。长期居住在月球已提上日
程，欧洲太空总署 (ESA) 正在寻找在月球上建造我们所需设施的方法，而无需将大量材
料拖到月球上。它的调查产生了一个奇怪的小实验。欧空局与乐高合作，使用一点超稀有
的陨石尘埃制作了一套“太空砖”。
The Space Bricks look like standard 8x2 Lego bricks, but you can tell
something's different up close. Despite its nearness in celestial terms,
there is very little lunar regolith on Earth. NASA has several hundred pounds
of material from the Apollo era, but more recent missions have only scooped
up tiny samples. The ESA team devised a solution that would allow them to
create testable Space Bricks without access to a pile of moon dust. The
secret ingredient was a 4.5-billion-year-old meteorite from Northern Africa.
太空砖看起来像标准的 8x2 乐高积木，但您可以近距离看出一些不同之处。尽管距离天
体很近，但地球上的月球风化层却很少。美国太空总署拥有阿波罗时代的数百磅材料，但
最近的任务只收集了微小的样本。欧空局团队设计了一种解决方案，使他们能够在不接触
月球尘埃的情况下制造可测试的太空砖。秘密成分是一颗来自北非的 45 亿年前的陨石。
Lego bricks aside, what we're really talking about here is an approach to
space exploration called in situ resource utilization, sometimes called ISRU.
Rather than bring everything from Earth, a mission can utilize the materials
available at the destination to save time and money. For example, ice
deposits hidden inside the "cold traps" of lunar craters could provide
astronauts with fuel, breathable air, and drinking water. Scientists have
also explored ways to use lunar regolith and Martian soil as a building
material. Hence, the Space Bricks.
抛开乐高积木不谈，我们在这里真正讨论的是一种称为原位资源利用（有时称为 ISRU）
的太空探索方法。任务可以利用目的地可用的材料来节省时间和金钱，而不是从地球带来
所有东西。例如，隐藏在月球陨石坑“冷阱”内的冰沉积物可以为太空人提供燃料、可呼
吸的空气和饮用水。科学家也探索了利用月球风化层和火星土壤作为建筑材料的方法。
对策，太空砖。
"No one has ever built a structure on the Moon, so we have to work out not
only how we build them but what we build them out of, as we can’t take any
materials with us," said ESA Science Officer Aidan Cowley.
欧空局科学官员艾丹·考利 (Aidan Cowley) 表示：“从来没有人在月球上建造过任何结
构，因此我们不仅要弄清楚如何建造它们，还要弄清楚用什么来建造它们，因为我们不能
随身携带任何材料。

The meteorite fragments (above) had large rounded grains (chondrules) and
smaller metal flakes. This material was mixed with a thermoplastic called
polylactide and simulated lunar regolith. The ESA used this mixture to 3D
print the Lego-inspired Space Bricks. The team says their experimental bricks
work a lot like the terrestrial versions. They have working "clutch power,"
which is the ability for the tiny studs and tubes to interlock securely. This
lets the team tinker with different structures to test the mechanics of their
imitation Moon bricks.
陨石碎片（上图）具有大的圆形颗粒（球粒）和较小的金属薄片。这种材料与一种称为聚
丙交酯的热塑性塑胶和模拟月球风化层混合。 ESA 使用这种混合物 3D 打印出受乐高启
发的太空砖。团队表示，他们的实验砖块的工作原理与地面版本非常相似。它们具有工作
“离合器动力”，即微小螺柱和管子牢固互锁的能力。这让团队可以修补不同的结构来测
试仿月球砖块的机械强度。
"It's no secret that real-world scientists and engineers sometimes try out
ideas with Lego bricks," said Emmet Fletcher, Head of ESA's Branding and
Partnerships Office. "ESA's space bricks are a great way to inspire young
people and show them how play and the power of the imagination have an
important role in space science, too."
“众所周知，现实世界的科学家和工程师有时会用乐高积木来尝试想法，”欧空局品牌和
合作伙伴办公室主任 Emmet Fletcher说。 “欧空局的太空积木是激励年轻人的好方法，
并向他们展示游戏和想像如何在太空科学中发挥重要作用。”
If you want to get a closer look at the Space Bricks, you might have an
opportunity this summer. Beginning this week, you'll be able to see 15 of
these bricks on display at several Lego locations, including the Lego House
in Denmark, the Lego store in Mall of America (Minnesota), the 5th Avenue
Lego Store (New York), and the Disney Springs Lego Store (Florida). The
exhibit will be present at all participating locations until Sep 20.
如果您想近距离观察太空砖，今年夏天您可能有机会。从本周开始，您将能够在多个乐高
地点看到其中的 15 块积木，包括丹麦的乐高之家、美国购物中心（明尼苏达州）的乐高
商店、第五大道乐高商店（纽约）、和迪士尼泉乐高商店（佛罗里达州）。该展览将于
9 月 20 日之前在所有参展地点展出。
