Keep in mind that time again in 2021 when a big container ship blocked the Suez Canal and disrupted environment shipping and delivery for a week? Very well, some thing a little like that is enjoying out all over again, this time in the Chesapeake Bay outdoors of the Port of Baltimore, exactly where the MV At any time Ahead ran aground more than a 7 days ago as it was headed out to sea. The good thing is, the mammoth container ship isn’t in rather as narrow a space as her canal-occluding sister ship At any time Specified was previous 12 months, so targeted visitors isn’t practically as impacted. But the recovery procedure is causing a stir, and refloating a ship that was drawing 13 meters when it strayed from the shipping and delivery channel into a muddy-bottomed spot that’s only about 6 meters deep is likely to be really a feat of maritime engineering. Service provider Maritime YouTuber Chief MAKOi has a good rundown of what’s going on, and what will be demanded to get the ship shifting all over again.

With the speed of deep-room exploration growing considerably of late, and with a full slate of missions planned for the future, it was excellent news to listen to that NASA extra yet another antenna to its Deep Space Community. The huge dish antenna, dubbed DSS-53, is the fourteenth dish in the DSN community, which spans 3 websites: Goldstone in California outside the house of Canberra in Australia and in Madrid, where by the new dish was installed. The 34-meter dish will incorporate 8% additional potential to the network that could not sound like significantly, but with the DSN at present supporting 40 missions and with near to that variety of missions planned, each individual minor bit counts. We come across the DSN fascinating, ample so that we did an posting on the procedure a couple of several years back. We also appreciate the insider’s scoop on DSN operations that @Richard Stephenson, one particular of the Canberra operators, delivers.

Does any person know what is up with Benchy? We bought a suggestion the other day that the trusty benchmarking tugboat product has gone lacking from numerous sites. It absolutely sure looks like Sketchfab and Thingiverse have deleted their Benchy data files, even though other web sites however seem to be to enable access. We poked around a little bit but couldn’t get a distinct photo of what’s going on, if everything. If anybody has information and facts, enable us know in the reviews. We positive hope this isn’t some variety of intellectual residence detail, the place you are heading to have to cough up money to print a Benchy.

Talking of IP protections, if you’ve at any time wondered how significantly a business will go to enforce its situation, glimpse no additional than Andrew Zonenberg’s “teardown” of an anti-counterfeiting label that Hewlett Packard makes use of on their ink cartridges. There is a dizzying array of technologies embedded inside what seems to be a straightforward label. In addition to the conventional things, like the minimal cuts that make it hard to peel a tag off 1 item and position it on yet another — frequently employed to thwart “price swapping” retail thefts — there is an virtually holographic location of the label. Zooming in with a microscope, the shade-shifting picture appears to be made from little hexagonal cells that almost glimpse like the pixels in an e-ink show. Zooming in even further more, the pixels supply an even bigger (scaled-down) shock. Get a search, and marvel at the exertion included in creating absolutely sure you fork out prime greenback for printer ink.

And lastly, we obtained a suggestion a few of weeks in the past on a video about jerry cans. If that seems unexciting, halt looking through ideal now — this a single will not access you. But if you’re even marginally interested in engineering layout and navy background, make guaranteed you watch this movie. What is now recognized to the US military as “Can, Gasoline, Navy 5-Gallon (S/S by MIL-C-53109)” and colloquially regarded as the NATO jerry can, began everyday living as the Wehrmacht-Einheitskanister, a 20-liter jug whose design addresses a very long list of technical specs, from the volume of liquid it could include to how the cans would be carried. The primary could provide as a learn class in excellent design and style, and some of the jugs that had been developed in the 1940s are continue to in services and actively sought by collectors of militaria. Low cost knockoffs are out there, of training course, but soon after watching this movie, we’ve developed a style for jerry cans that only the unique will sate.
