Another batch of the Starlink space wifi routers launched. https://youtu.be/Yov854ZT1lg?t=1210 shows the 2nd stage's exhaust plume as seen from the launch site. I've never seen this before.
Also, better-than-usual video feed from the ASOG drone ship.
Somehow I miss the Guldens, the Francs, the Schilling, and... especially the Lira. It brought a certain touch to every travel abroad. For the Lira, you had to bring a big wallet... Switzerland has accepted the Euro as payment nearly everywhere. You will lose a few percent, though, but ticket vending...Jump to post
On JWST web site , you see that the hot side of that thing is about +60 °C, but the cold one is about -190 °C. All a Stirling engine does is converting a temperature difference into motion, which in turn could drive a generator. Apart from introducing more movable parts (and thus more failure modes)...Jump to post

I'm already looking for WiFi options in order to watch the launch in spite of a family Christmas dinner. About hundred years ago, there was the so-called Great Debate whether our galaxy was the only one, and as a consequence, whether our galaxy was the entire universe.

My favorite explanation of Lagrange points is simply "Physicists hated the popularity of Kerbal Space Program, and so they invented Lagrange points and the three-body problem." As for why JWST need to circle around the L2 point itself I don't really know, all I know is that this is common ...Jump to post
One cannot infer future stock prices from past ones. A trend that held until today can fail tomorrow. The only sensible thing is fundamental analysis, like analyzing how much knowledge the company has, whether their managers can actually address problems without reprisals, and knowing which forces a...Jump to post

Crude oil and natural gas are not only fuel, but also very valuable input materials in chemical processes, e.g. in manufacturing fertilizer and plastics. This material does not lose its value, no matter how heavily fossil fuels will be taxed.Jump to post
The Gotland submarine has a Stirling engine, which allows the sub to run quieter and it can submerge for a much longer time (something previously only the nukular subs could do). The Norwegian subs are German-built, and probably the best attack submarines in the world. The German ones are specialize...Jump to post

I tried watching the 1967 version but I don't have the patience for it. Coming off the 2006 film and then going back is rough. Had the same thing with Nightmare on Elm Street. Watched the remake before the original. Oh well, my mistake. That's nothing. The worst thing is watching "Dr. Strangel...Jump to post
It's been said on this thread that the Il-76 has an engine that needs an overhaul every 2,000 hours. That engine, the D-30KP, is a very old design and is not installed on new built Il-76s. New built Il-76s get a completely new engine, the PS-90. https://en.wikipedia.org/wiki/Aviadvigatel_PS-90 Stil...Jump to post
For any given military, the price is rarely the main reason to buy (or not to buy) something. It's rather: How does the plane complement our existing capabilities? And how can the plane be maintained if we're cut off from the manufacturing countries? And sometimes it's just about maintaining develop...Jump to post
The wonderful word of crypto... Some inventive people created a currency related to the Squid Game TV show. One inherent feature of that crypto currency was that you can only buy it, but not sell. This ensured rising prices. In turn, this attracted more buyers. But the biggest red flag was that no o...Jump to post

The science of the gigantic ocean currents goes back and forth on this. I understand there are no adequate mathematical models, and even data is more sparse than needed. Lots of work being done on this, of course. I'm not specialized in climate change, but in science there is usually little debate....Jump to post

I've watched NTTD twice. The first time around I was very sleepy... suffered from insomnia the entire night before.

Financially, it was terribly inefficient. It was a costly prestige project of two governments. But organizing the project and the multinational collaboration among the engineers and manufacturers was a masterpiece. It also led to a lot of useful know-how.
Musk kicked in $50M towards the funding goal for St Judes. Earlier this evening it sounded to me like they were well short of their $200M goal.
