SpaceX vs. China: The Quest for Satellite Internet
SpaceX has more than 1,000 satellites beaming high-speed internet to Earth, but China promises to offer higher speeds with the launch of what it calls the world’s first 6G satellite. Here’s how both are on a quest to build powerful internet networks in space. Photo illustration: Sharon Shiwww.wsj.com
Remember when Trump suggested skipping 5G and going directly to 6G and he was mocked?SpaceX vs. China: The Quest for Satellite Internet

This is a NOV ADS-30Q from Drawworks Hoisting SystemThey appear to be constructing a shed or cage around it too, in case there was any doubt about its permanence:
Curiously, that construction of such exotic buildings and advanced rockets have been accomplished with off-the shelf machinery, materials and tools, used in proper places and situations. Super-heavy-load cranes, stainless steel welding could be used anywhere - and played the crucial roles in the building of most advanced space technology
Either it's for Launchtower crane or this system that catch returning Superheavy
Steampunk rocket !! Well, Steelpunk might be more appropriate... or Steelpuck !
I would be more surprised if they weren't. Many of these groups are for sale.Yet another manifestation of the insanity of the times, I'm afraid. Though I wouldn't be surprised if it ultimately turns out that they were being used by other interests, domestic, foreign, or both.
It's called "astroturfing" i.e., fake grass roots.Yet another manifestation of the insanity of the times, I'm afraid. Though I wouldn't be surprised if it ultimately turns out that they were being used by other interests, domestic, foreign, or both.
Which part are you seeing as a problem specifically?Yes yes, machine there is. But what you have on your FEA analysis depends on mesh geometry whish are sensible to acute angles and elongated portions. Then the delta b/w true and real is aggravated. Add build and weld quality and you are expending something out of a reasonable range where cheap and safe prevails.
The result is a thicker section that would be useful only on the joint but you carry through the entire length of the pipe, often, the frame assembly and a weight increase that you pay as an extra load to carry, in material, shipping and on-site tooling...
All that for a sin(15) extra length...
Example?Many to be honest.
I don't have an answer there. Maybe the person/company doing the design doesn't have a lot of experience with that kind of structure and "it passed FEA so it's good enough". Too many unknowns. Did they do it in house or sub it out? I'd think if you had someone who specialized in that kind of structure they'd have optimized it.
Don't want to scare someone - but these are Martians! They assembled their dangerous tripods in Boca-Chica, and soon start their conquest of the world. Beware of "Heat-Ray" and "Black Smoke".
