Tech ingredients has some interesting videos on microwave crowd control weapons, and how to defeat them. It’s mostly metal mesh in your cloths or a shield.

Moscow repeated that any settlement must address “the root causes of the crisis”

Agreed, we need to get rid of Putin, the root cause.

Ukraine’s infrastructure strikes have been some of their most cost educative, whereas it’s baffling why Russia is investing so many missiles into infrastructure attacks with so little result. Russia would need to offer concessions to induce a mutual infrastructure attack pause, not the other way around. Makes me think it’s a ploy to look like they’re offering something without actually offering anything.

Ukraine helped. Also, they’re taxed at almost exactly their profit to maximize state revenue. It’s not quite state owned, but it’s close.

They tend to sensor criticism of China for one.

That puts it at a 12C charge rate. The question is how the batteries will hold up over time. Does each fast charge cycle make a noticable degradation to the capacity?

If they’re using LFP it’s probably okay, they can usually take higher charge and discharge rates at the cost of lower energy density. But I’d be worried if they’re pushing NMC battery chemistries to 12C, as I think that’d kill the life of the battery.

If you’re using a 50 year time frame, and as much methane leaks as some research suggests, natural gas actually has a higher tons of co2 equivalent per kwh than coal does.

You saying shut down the engines from the ground? The vehicle computer would have a much better understanding of the system than the people on the ground during those first minutes. I’m guessing they just needed to trust their programming at that point.

250 days would be 5 days a week 50 weeks a year, so seems similar to modern schedules.

Wasn’t the original novel just pro fascist, but the movie made it into a ‘pro fascist’ satire? Or am I remembering that wrong?

It’d take a miracle!

One of the reasons I prefer something like the Russell 2000

Is there a way of cropping with default apps on mobile?

Also, I don’t think the engines provide electrical power, that’d be from the batteries.

Edit: yeah, they use helium to spin the turbo pumps, so no electrical generator/motor on raptor.

Two engines exploded, blowing the back of the ship up, causing the ship to tumble, which lead to loss of communication a few minutes later. Abort was absolutely the right call. Saying communications need to be better is like saying you need a better bandaid for your stump of an arm after you blew it off with a grenade.

The communications failed because the ship was spinning faster and faster, and eventually the antenna tracking couldn’t keep up.

As soon as the engines exploded, the mission was dead, so the best thing is to abort, which is what they did.

-The incident highlights significant operational failures, as engine shutdowns should not cause communication loss, indicating a lack of redundancy in systems.

• SpaceX’s pre-flight checks failed to identify potential leaks, suggesting inadequate safety measures or poor execution of checks.

These points are really silly. Two engines exploded causing the ship to tumble. I’m not sure what they think additional communications redundancy would help with at that point.

And how do you indefiy a fuel leak on the ground that hasn’t happened yet? It was caused by vibrations at a resonant frequency that is only reached at a certain fuel level?

• Starship’s design has been criticized for overestimating engine thrust capabilities, limiting its payload capacity to 40-50 tons, which is less than the Saturn V.

Who said that? That’s really silly. And isn’t that payload with full reusability?

Space is hard, it’s literally rocket science. The embarrassing thing is it failed in the same way twice. But finding these resonance issues that only pop up in specific fuel states, makes sense it’s hard to pin down. I think they’ll need to characterize their vib spectrum as fuel burns down, then analyze the harmonics of the hardware and make sure they don’t couple. It isn’t easy, but they should be able to.

Edit: thanks for the summary, I just disagree with the article.

Awesome, thank you, I’m not very familiar with ancient American history.

Maybe they’re taking about qr code pictures?

The top one doesn’t even exist. It was announced 8 years ago now.
