LEGO Bricks: Now Out Of This World

Now the eyes of space explorers are turned once more towards the Moon, there are a whole host of new engineering challenges facing engineers working on lunar missions. One such challenge relates to how any proposed Moon base might be built, and as European Space Agency (ESA) researchers turn their mind to the problem they’ve taken a uniquely European approach. They’ve made some LEGO bricks.

Sadly lunar regolith is in short supply in Europe at the moment, so as a stand-in they’ve ground up a meteorite, mixed the powder with a polymer, and 3D printed their bricks. The LEGO write-up is a little long on frothy writing style and a little short on the science, but it seems that they clutch in exactly the same way as the official bricks from Billund, and can be assembled just as you would a normal set of bricks.

It’s with some regret that we have to concede that Europe’s off-planet outpost won’t be crewed by LEGO people in a base made from LEGO bricks, but we applaud them for doing this as a practical test given the limited supply of starter material. LEGO themselves have snagged some of them to display in a range of their flagship stores, so we hot-footed it down to London to catch some pictures. What we found is a single brick in a glass case, sadly looking very like any other 3D printed brick in a shiny grey medium. It’s probably the most expensive brick in the world though, so we doubt they’ll be available to buy any time soon.

If you’re hungry for more of all things LEGO, we can do no better than suggest a trip to the mother lode, in Billund, Denmark.

Enjoy Totality Every Day With This Personal Eclipse Generator

There have been a couple of high-profile solar eclipses lately, but like us, you probably missed the news of the one that passed over Munich in 2019. And every day since then, in fact, unless you were sitting in a particular spot: the couch of one [Bernd Kraus], who has his very own personal eclipse generator.

We’ll attempt to explain. Living in an apartment with a gorgeous western view of Munich is not without its cons, chief among which is the unobstructed exposure to the setting sun. Where most people would opt for a window treatment of some sort to mitigate this, [Bernd] felt that blotting out the entire view was a heavy-handed solution to the problem. His solution is a window-mounted X-Y gantry that dangles a cutout of the moon in just the right place to blot out the sun. An Arduino uses the time and date to calculate the position of the sun as it traverses the expansive window and moves the stepper motors to keep the moon casting its shadow in just the right place: on his face as he sits in his favorite spot on the couch.

There are a couple of time-lapse sequences in the video below, as well as a few shots of the hardware. We know this isn’t an actual coronagraph, but the effect is pretty cool, and does resemble an eclipse, at least in spirit. And it goes without saying that we applaud the unnecessary complexity embodied by this solution.
