Could Moon Dust Help Reduce Global Temperatures?

The impacts of climate change continue to mount on human civilization, with warning signs that worse times are yet to come. Despite the scientific community raising an early warning as to the risks of continued air pollution and greenhouse gas output, efforts to stem emissions have thus far had minimal impact. Continued inaction has led some scientists to consider alternative solutions to stave off the worst from occurring.

Geoengineering has long been touted as a potential solution for our global warming woes. Now, the idea of launching a gigantic dust cloud from the moon to combat Earth’s rising temperatures is under the spotlight. However, this very sci-fi solution has some serious implications if pursued, if humanity can even achieve the feat in the first place.

There are plenty of stories floating around about the war in Ukraine, and it can be difficult to sort out which ones are fact-based, and which are fabrications. Stories about the technology of the war seem to be a little easier to judge, and so stories about an inside look at a purported Russian drone reveal a lot of interesting technical details. The fixed-wing UAV, reported to be a Russian-made “Orlan,” looks quite the worse for wear as it’s given a good teardown by someone wearing Ukraine military fatigues. In fact, it looks downright homemade, with a fuel tank made from what looks like an old water bottle, liberal use of duct tape to hold things together, and plenty of hot glue sprinkled around — field-expedient repairs, perhaps? The big find, though, is that the surveillance drone carried a rather commonplace — and cheap — Canon EOS Rebel camera. What’s more, the camera is nestled into a 3D printed cradle, strapped in with some hook-and-loop tape, and its controls are staked in place with globs of glue. It’s an interesting collection of hardware for a vehicle said to cost the Russian military something like $100,000 to field. The video below shows a teardown of a different Orlan with similar results, plus a lot of dunking on the Russians by a cheery bunch of Ukrainians.
