Recall that time back in 2021 when a substantial container ship blocked the Suez Canal and disrupted planet shipping and delivery for a week? Well, anything a tiny like that is enjoying out yet again, this time in the Chesapeake Bay exterior of the Port of Baltimore, wherever the MV At any time Forward ran aground in excess of a 7 days back as it was headed out to sea. The good news is, the mammoth container ship isn’t in rather as slender a space as her canal-occluding sister ship Ever Given was last calendar year, so site visitors isn’t almost as impacted. But the restoration procedure is producing a stir, and refloating a ship that was drawing 13 meters when it strayed from the transport channel into a muddy-bottomed area that’s only about 6 meters deep is heading to be fairly a feat of marine engineering. Service provider Maritime YouTuber Chief MAKOi has a excellent rundown of what is heading on, and what will be necessary to get the ship relocating all over again.

With the speed of deep-place exploration rising dramatically of late, and with a full slate of missions prepared for the potential, it was good information to hear that NASA extra a further antenna to its Deep Space Community. The huge dish antenna, dubbed DSS-53, is the fourteenth dish in the DSN network, which spans 3 web sites: Goldstone in California outside of Canberra in Australia and in Madrid, where the new dish was set up. The 34-meter dish will add 8% a lot more potential to the network that might not sound like considerably, but with the DSN presently supporting 40 missions and with shut to that selection of missions planned, every single very little little bit counts. We obtain the DSN intriguing, more than enough so that we did an report on the program a number of yrs back. We also enjoy the insider’s scoop on DSN functions that @Richard Stephenson, one particular of the Canberra operators, offers.

Does any one know what’s up with Benchy? We acquired a idea the other day that the trusty benchmarking tugboat product has absent missing from several internet sites. It confident seems like Sketchfab and Thingiverse have deleted their Benchy documents, even though other web-sites still appear to be to enable access. We poked all over a bit but could not get a very clear image of what is going on, if just about anything. If anyone has details, let us know in the responses. We confident hope this is not some variety of mental assets thing, where you’re heading to have to cough up income to print a Benchy.

Talking of IP protections, if you’ve ever wondered how far a firm will go to enforce its posture, search no even more 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 inside of what appears to be a easy label. In addition to the conventional stuff, like the small cuts that make it complicated to peel a tag off just one item and put it on yet another — frequently made use of to thwart “price swapping” retail thefts — there’s an nearly holographic region of the label. Zooming in with a microscope, the colour-shifting impression seems to be built from little hexagonal cells that just about seem like the pixels in an e-ink show. Zooming in even further more, the pixels supply an even larger (lesser) shock. Acquire a search, and marvel at the hard work associated in generating confident you fork out top rated dollar for printer ink.

And ultimately, we got a tip a few of months back on a movie about jerry cans. If that sounds unexciting, quit studying suitable now — this a single will not attain you. But if you’re even marginally interested in engineering design and military services history, make confident you observe this video clip. What is now recognised to the US army as “Can, Gasoline, Navy 5-Gallon (S/S by MIL-C-53109)” and colloquially identified as the NATO jerry can, begun lifestyle as the Wehrmacht-Einheitskanister, a 20-liter jug whose style and design addresses a extensive record of specifications, from the quantity of liquid it could comprise to how the cans would be carried. The original could provide as a master course in very good design, and some of the jugs that were being built in the 1940s are still in company and actively sought by collectors of militaria. Low-priced knockoffs are out there, of course, but following looking at this video, we have formulated a flavor for jerry cans that only the authentic will sate.
