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."
人類正準備幾十年來首次飛出近地軌道，這次的訪問不會很快。長期居住在月球已提上日
程，歐洲太空總署 (ESA) 正在尋找在月球上建造我們所需設施的方法，而無需將大量材
料拖到月球上。它的調查產生了一個奇怪的小實驗。歐空局與樂高合作，使用一點超稀有
的隕石塵埃製作了一套「太空磚」。
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.
太空磚看起來像標準的 8x2 樂高積木，但您可以近距離看出一些不同之處。儘管距離天
體很近，但地球上的月球風化層卻很少。美國太空總署擁有阿波羅時代的數百磅材料，但
最近的任務只收集了微小的樣本。歐空局團隊設計了一種解決方案，使他們能夠在不接觸
月球塵埃的情況下製造可測試的太空磚。秘密成分是一顆來自北非的 45 億年前的隕石。
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.
拋開樂高積木不談，我們在這裡真正討論的是一種稱為原位資源利用（有時稱為 ISRU）
的太空探索方法。任務可以利用目的地可用的材料來節省時間和金錢，而不是從地球帶來
所有東西。例如，隱藏在月球隕石坑「冷阱」內的冰沉積物可以為太空人提供燃料、可呼
吸的空氣和飲用水。科學家也探索了利用月球風化層和火星土壤作為建築材料的方法。
對策，太空磚。
"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.
歐空局科學官員艾丹·考利 (Aidan Cowley) 表示：「從來沒有人在月球上建造過任何結
構，因此我們不僅要弄清楚如何建造它們，還要弄清楚用什麼來建造它們，因為我們不能
隨身攜帶任何材料。

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.
隕石碎片（上圖）具有大的圓形顆粒（球粒）和較小的金屬薄片。這種材料與一種稱為聚
丙交酯的熱塑性塑膠和模擬月球風化層混合。 ESA 使用這種混合物 3D 列印出受樂高啟
發的太空磚。團隊表示，他們的實驗磚塊的工作原理與地面版本非常相似。它們具有工作
“離合器動力”，即微小螺柱和管子牢固互鎖的能力。這讓團隊可以修補不同的結構來測
試仿月球磚塊的機械強度。
"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."
「眾所周知，現實世界的科學家和工程師有時會用樂高積木來嘗試想法，」歐空局品牌和
合作夥伴辦公室主任 Emmet Fletcher說。 “歐空局的太空積木是激勵年輕人的好方法，
並向他們展示遊戲和想像如何在太空科學中發揮重要作用。”
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.
如果您想近距離觀察太空磚，今年夏天您可能有機會。從本週開始，您將能夠在多個樂高
地點看到其中的 15 塊積木，包括丹麥的樂高之家、美國購物中心（明尼蘇達州）的樂高
商店、第五大道樂高商店（紐約）、和迪士尼泉樂高商店（佛羅里達州）。該展覽將於
9 月 20 日之前在所有參展地點展出。
