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."



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.


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.


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.

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.



"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."



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.


9 月 20 日之前在所有參展地點展出。
