How about Hydrogen electrolysis? The fuel cell efficency shouldnt matter to much since they need heat during the night anyway. And hydrogen is usefull for lots of other stuff...

Definetly, but wait for the 8. october. AMD will present their new CPUs there, and its highly likely that the new ones will eclipse Intels most recent offerings, as even their current generation is on par and there are rumors of about 15% increase in IPC.

It didnt even rip at the welds, realy impressive.

Thats no problem. The PSU can deliver 360W of 12V, thew GPU needs about 125W, the CPU including RAM and Mainboard will stay below 125W. Even with the other devices you wont reach more than 300W under full load.

Do i understand correctly that the SAOCOM 1B booster will land at LZ-1 and the one from Starlink on the barge?

Regarding testing vacuum engines in normal atmosphere: This is how they do it. If i understand that correctly the engine exhaust "sucks out" ambient air from the diffuser, creating a lower pressure within. The picture from one of the coolest blogs ive ever read: https://blogs.nasa.gov/J2X/ Sadly the J2X engine was shelved among the clusterlove of SLS developement...

https://en.wikipedia.org/wiki/Pioneering_Spirit_(ship) Something like this?

I remember seeing them a long time ago, so not new.

I guess not, thats why they are testing them...

Its extremly annoying to see this stuff only in videos. Its mostly still images, only people are moving a bit. Is there a summary with just pictures somewhere?

Thats a mean burn for Lockheed Martin and Airbus, who both operate their own launch vehicles

It seems realy strange they just went for some bitcoins. Having access to such high level Twitter accounts would open way bigger possibilities. It just starts at stock market manipulation, e.g. Elon Musk "announcing" that Tesla is being bought by Apple and them confirming it. When it comes to political twitter accounts (especialy Trumps) there is great potential to cause real life violence.

The i7 is the most limiting factor here, but even upgrading to the fastest currently available CPU wouldnt bring you a noticable benefit.

It seems that US unions are bad at doing their job. In Germany unions are powerful counters to the employers, at least in more skilled jobs where most of the employes are in a union. They usualy ensure high wages, good working conditions, help with legal battles and make sure that workers arent simply another resource for the company but also have power over the decisions, especialy when it comes to laying of workforce. Sometimes the power of the unions come at a cost, for example if pilots or traindrivers go on strike and cripple a whole country to fight for higher wages/better conditions for a small fraction. But imho thats a small price to pay...

I guess it wont get much better than this...

Did you install the correct graphics driver for it? Edit: This one: https://www.amd.com/de/support/apu/amd-ryzen-processors/amd-ryzen-3-desktop-processors-radeon-vega-graphics/amd-ryzen-3-0

You could try to save some money with buying a used GPU or CPU, there should be lots of Ryzen 1000/2000 available since a lot of people upgraded to an 3000 series one. Similary with RX 470/480/570/580.

Not realy, large partcounts will mostly stress the CPU. But even high end PCs are not able to launch something like in your last picture smoothly... There is also a Demo of KSP which is quite old (Version 1.0), you could try that. Not sure where to find it, though.

@Hoozemans Im not sure if you can check the current clockspeed of the CPU during KSP on a Mac, you would need some kind of overlay for that and i have no idea if that stuff is possible on a Mac. But that i9 isnt much slower in single-core speed than even the fastest desktop CPUs, its only possible that it throttles due to bad cooling in the laptop. So if there is no throtteling you wont get a noticable gain with even an i9-10900k since that runs only about 10% faster...

From what i know you would need to install Linux on it first, assuming you have an x86 CPU. But even then it will be realy slow since Chromebooks come with the slowests CPUs available, often a dual core Atom one. You could try the demo before a purchase, but i doubt you will have any fun with this.

When Dragon decoupled the camera was "backwards" compared to the second stage burn. This confused me for a few seconds, it looked like we saw a Dragon that just decoupled its trunk together with the second stage. That would have been realy embarrasing...

Scott Manley has the invite link to the Discord channel in his Youtube channel info, so i guess its open to anyone.

After playing with the simulator im wondering about the actual accuracy of the Dragon 2 when it comes to velocity changes. A Draco thruster delivers 400N, the whole Dragon 2 including cargo has a mass of about 15t. I guess for translation you need two thrusters at once, so 800N/15000kg = 0,05m/s^2. Im sure a burst can be shorter than 2 seconds, so IRL they will have smaller increments than 0,1m/s as in the simulator. Does anyone know whats actualy the shortest burst of such RCS thrusters and thus the smalles possible speed change?

Either Crew-Dragon became realy cheap or the budget of that movie breaks the record of currently 379m$...
