Glonass-K launch out of Plesetsk nominal, no Kosmos number yet as far as I see

Exteme TWR in LRPEs was mostly attempted through exotic, high-density propellants. At one point, some madman tried a mercury compound.

The blast doors of Bunker 703 (Special Archives of the Foreign Ministry), Moscow is a 10-ton ferrocrete slab. The fun fact is, actuators (purely mechanical ones in the mid-1950s through to 1981) are located exclusively on the outside of the bunker entryway. Before the addition of an electric motor with buttons on either side, the only way someone from inside the bunker was supposed to open it was with a crowbar. No, the guys that set uo a museum there have no idea why this was the choice made. The gasproof doors (such as the one behind the blast door) are an ordinary hand-operated "quick-acting" design.
Granted, if something on the other side of the blast door was holding it in place, anyone inside was supposed to use the escape tunnels (without full blast doors) into a subway service trunk.

Would the best orbit for an International space station(Not the real one) be polar? It would make it so every country can launch to it.
But is there a relevant country that can't secure access to a launch site as close or closer go the equator than Baikonur?

Is it possible to induce a region-level atmospheric radio wave blackout through ionosphere excitation?
Got a word of mouth Starlink outage 'conspiracy' theory here (that's not limited to Starlink, but claims GSO comm disruption as well).
-
Unfortunately, I didn't communicate the problem to my parents - and they dismissed it as calusses or minor wounds from rocks - until I had a total of 52 warts over both feet, a thumb and an index finger.
That freezing campaign... wasn't fun.

Allow me to derail this absolutely serious discussion with some tomfoolery.
Panorama, satire, October 3rd: "Starlink internet stops working across Ukraine for 'unknown reasons'"
The Financial Times, not satire, October 7th: "Ukrainian forces report Starlink outages during push against Russia"
They do say The Onion and their ilk are the most reliable news sources out there...
SpoilerBack to seriousness, though, the version suggested by Ukranian officials is dubious. Unofficial Russian channels have consistently suggesting against using captured Starlink terminals as anything other than coffee tables - apparently, almost all lost terminals are quickly accounted for, and their Internet access is disabled. A follow-on artillery strike on the guys fiddling with the terminals is optional, but likely.
Instead, Russian sources suggest a local application of Tirada-2 ECM.

What's pushing an Orion drive spacecraft? From what I know, the only reason a nuke will blow things away is because the heat causes air to expand and push objects. But there's no air in space, so the only thing that could be propelling the spacecraft is the small amount of mass in the bomb itself and the light energy.
Ah, you missed a key feature. The Orion drive units are CASABA-HOWITZER shaped nuclear charges firing a blast of hypervelocity tungsten plasma in a cone about 22⁰ wide, aimed at the launching spacecraft.

Mine-resistance ambush-protected vehicles are designed with the titular purposes in mind, complete with a V-shaped hull and as much distance between the wheels and the backsides of the passengers as possible. This makes them rather top-heavy and flip-prone.
Because of that, they get training wheels.

The folks I talked to in English had either Perfect American Midwest accents or Perfect Cambridge British accents. Not kidding. You'd start talking in English to a room full of Germans, and it would be like a convention of Americans and Brits who use odd phrases. Like "I need to go look for a parking." (In American English, you look for a 'parking spot'. 'Parking' is the verb describing what you do as you pull into the spot, or what your grandmother did with boys before she met your grandfather.) Their accents were so good I actually had to confirm they were native German speakers.
Germans are said to get hit with the same sorr of dissonance. Foreign speakers learn the idealized Hochdeutsch and lack the usual regional accents.

Ended up getting a whopping 17 years, starting with first grade and continuing all the way through Masters'. However, I slacked off and very rarely got technical, learning much of the language through sheer emulation of consumed media (hence I'm quite mum on the whole phonetics discussion). The result is some puzzling mixture of American and British, topped by the very detectable Russian accent (especially if I've just "switched gears")... and the general slurriness and excessive speed.

Are you suggesting that starship-centaur is valid?
Centaur-Anything is valid with a proper "corset". After all, all the design work on Shuttle-Centaur was complete.

Why is the centaur used so much in spaceflight? When can I expected the Starship-centaur
RL-10 is good, baloon tanks are light. Why mess with perfection? And all things considered, your question might not be too far out there.

Now, if you would allow me to direct your attention to the draft 2023 federal budget right here:
https://sozd.duma.gov.ru/bill/201614-8
According to Annex 12 (out of the 592 files bundled in with the draft, jeez), page 1904, Roscosmos is allocated 236 bln RUB, vis a vis 191 bln RUB for 2022.
https://spending.gov.ru/budget/grbs/730/
Some say Borisov only took the job on the condition that "his pie" got 30% bigger...

The main engine of the economy is shut off
It's so shut off it's been flooding us with unprecedented amounts of cash (the significant difference between Russian and global rouble-dollar exchange rate was one sign), and OPEC+ is negotiating another supply squeeze deal right in the face of preparations for the vaunted 'price cap' (which is already getting so many caveats added it's going to be a complete joke - simultaneously decreeing that third-party processed Russian oil isn't subject to restrictions and vowing not to sanction violators of the price cap).
Treating either combatant in this war as a house of cards about to collapse has proven to be an abysmal approach.

65th anniversary of Sputnik, and the Ministry of Defence decides to slop6in that it "conducts experiments with other nations' satellites in orbit".

Is Elon Errolovich really that excited about Dmitry Olegovich's likely imminent new job?

but to be totally fair, I don't think cross-range capability has ever been utilized
It hasn't been. But then nor have there ever been a true spaceplane combat sortie mission.
Yet.

How? I thought it was an cool idea, now stealing one of them would make you an very effective car thief.
But I assume main use is to pack cars tighter, double parking just require you to move another car first.Well, for starters, the sign of a car inexplicitly starting to creep across the parking lot is going to get quite a few jaws to drop.
Plus, the first thing I think of at the sight of that thing is a trip to the impound lot.

Bit of a marginal but honest question, but I've stumbled upon the scene of a major thrashing Ian has given to the aircraft at North Perry, FL.
https://yuripasholok.livejournal.com/13963724.html
Wouldn't people either keep their aircraft away from the capital state of hurricanes for the hurricane season, or be close enough to bolter out of there at the first sign of trouble?

The problems are mainly the high construction costs and the deadly consequences of a hull breech. However, the bigger problem is, indeed, the purpose of such a project. We don't have a space problem, as correctly indicated by @Kerbaloid, and even where we do it's cheaper to pack more humans into the available km² (looking at you, American suburbia and certain hyperurbanized Aftican countries). As to food, it's agains not immediately obvious why you'd move people closer to an algae farm rather than just moderately improve logistics.

Storms and anchors and maritime traffic. There'd be a hissy fit if areas of shallow ocean near coastlines of major countires became off-limits for traffic.

-1 (already badly worn) NASA T-shirt. Snagged it on the door handle, tore right through.
But trying to photo the big white cat that's strayed into our driveway was a noble cause.
