Remember that time back again in 2021 when a big container ship blocked the Suez Canal and disrupted planet transport for a week? Nicely, some thing a tiny like that is enjoying out once again, this time in the Chesapeake Bay outdoors of the Port of Baltimore, the place the MV At any time Forward ran aground about a week ago as it was headed out to sea. Fortunately, the mammoth container ship is not in really as slender a space as her canal-occluding sister ship At any time Presented was very last calendar year, so targeted visitors is not virtually as impacted. But the restoration procedure is creating a stir, and refloating a ship that was drawing 13 meters when it strayed from the shipping channel into a muddy-bottomed place that is only about 6 meters deep is going to be rather a feat of marine engineering. Merchant Maritime YouTuber Chief MAKOi has a great rundown of what’s likely on, and what will be demanded to get the ship transferring once more.

With the tempo of deep-house exploration rising considerably of late, and with a complete slate of missions prepared for the foreseeable future, it was good news to listen to that NASA additional another antenna to its Deep Space Network. The enormous dish antenna, dubbed DSS-53, is the fourteenth dish in the DSN network, which spans three sites: Goldstone in California outdoors of Canberra in Australia and in Madrid, exactly where the new dish was mounted. The 34-meter dish will incorporate 8% additional capacity to the network that may possibly not seem like significantly, but with the DSN currently supporting 40 missions and with close to that variety of missions planned, each and every minor little bit counts. We obtain the DSN fascinating, adequate so that we did an post on the program a handful of decades in the past. We also really like the insider’s scoop on DSN functions that @Richard Stephenson, just one of the Canberra operators, offers.

Does any one know what’s up with Benchy? We obtained a tip the other working day that the trusty benchmarking tugboat model has absent lacking from many sites. It guaranteed appears to be like like Sketchfab and Thingiverse have deleted their Benchy information, even though other websites nevertheless seem to enable entry. We poked all-around a bit but could not get a apparent photograph of what’s heading on, if nearly anything. If any one has information and facts, allow us know in the opinions. We guaranteed hope this isn’t some sort of intellectual residence detail, where you’re going to have to cough up funds to print a Benchy.

Speaking of IP protections, if you’ve ever wondered how far a business will go to enforce its place, glance no further than Andrew Zonenberg’s “teardown” of an anti-counterfeiting label that Hewlett Packard employs on their ink cartridges. There’s a dizzying array of systems embedded within what appears to be a easy label. In addition to the common stuff, like the very little cuts that make it difficult to peel a tag off one particular product and spot it on a further — typically used to thwart “price swapping” retail thefts — there is an pretty much holographic location of the label. Zooming in with a microscope, the coloration-shifting picture seems to be designed from small hexagonal cells that virtually seem like the pixels in an e-ink show. Zooming in even even more, the pixels provide an even greater (smaller) shock. Acquire a seem, and marvel at the energy associated in making absolutely sure you spend major dollar for printer ink.

And lastly, we acquired a idea a pair of months back on a video clip about jerry cans. If that appears dull, prevent reading suitable now — this one won’t access you. But if you’re even marginally fascinated in engineering design and armed service historical past, make absolutely sure you view this online video. What is now identified to the US military services as “Can, Gasoline, Navy 5-Gallon (S/S by MIL-C-53109)” and colloquially recognised as the NATO jerry can, started existence as the Wehrmacht-Einheitskanister, a 20-liter jug whose style addresses a extensive record of specs, from the volume of liquid it could comprise to how the cans would be carried. The unique could serve as a learn class in good design, and some of the jugs that ended up constructed in the 1940s are nonetheless in service and actively sought by collectors of militaria. Affordable knockoffs are out there, of study course, but immediately after watching this online video, we have formulated a style for jerry cans that only the initial will sate.
