You mean you want to place some nuclear-powered missiles (that aren't even designed for spaceflight AFAIK?) with nuclear warheads into orbit and then blow them up on GPS sats? There are probably better ways to disable GPS without violating the Outer Space Treaty, but if you want to... Using an LV performance calculator, quick data from Wikipedia, and guessimation where I didn't immediately find required data, I pressed the data in (assuming the rocket is equipped with a Briz-M third stage) and got results: https://imgur.com/a/jKpoAum So using my Mostly Unreliable Data™ you can launch about 1700 kg into a GPS orbit with an Angara. To be taken with a handful of salt.

Is the Dragon 2 connected to the Canadarm on this picture, or what? Using the Canadarm would technically mean it berthed instead of docking.

The proper name is indeed "mess", either "crew's mess" or "officers' mess"/"wardroom". For space stations, we cannot know yet for sure (most likely will be "mess" just like in ships), although for any foreseeable modular space station design there is no distinct mess module as the typical maniacal mass-saving leads astronauts to eating anywhere they can do that, and the ISS normally has only six crew. Additionally, in zero-g it is not always required to use a table. On the other hand, having at least a partially enclosed space for a mess might help prevent food from getting everywhere, although space food is chosen so that you don't have to clean any breadcrumbs after eating...

Is there some software that would allow me to convert my morse code, made by pressing a key on the keyboard, into a graphics format, like a digital version of a physical machine writing received signals on tape?

For Tylo of Jool... I thought that is impossible to build! I assume it uses mods for propulsion, and its engines or whatever are not located where they are in the actual Star Trek vessel, or otherwise it would have imbalanced thrust problems?

Why do passenger cars usually have a "pushed-in" area on the doors, between the wheels, marked with a red arrow on the picture below? Or, as one might say, "pushed-out" wheel covers relative to the rest of the car's body? Is that good for aerodynamics, or some other weird technical reason, or perhaps just an artistic design trend?

The title of this video is a violation of the second law of thermodynamics. So to build this device, we would have to find an alternate universe.

Hey, nothing wrong with 1 atm of pressure at 320 K -- if you're an balloon fanboy.

Block 5 will still get improved, by the time it gets to 24 hour multi-reuse it might well be called "block 6", however these upgrades are likely going to come out with every launch, so no more revolutionary "blocks".

If a nuclear reactor gets rid of primary loop water (the water in contact with the core), how are radioactive elements typically removed from it?

Anyone knowing other transportation contrivations safer than a car would be appreciated

Space rockets are basically supersonic rc drones This is a target drone converted F-16 (the QF-16), I do not know if it ever flew supersonic operationally but it definitely can still do that: If you mean amateur aircraft without rocket propulsion, the fastest speed according to Guinness World Records is still corresponding to the end-of-ww2/superprop speeds: http://www.guinnessworldrecords.com/world-records/fastest-remote-controlled-jet-powered-model-aircraft-(rc)

[insert politician saying "wrong" meme here] In my definition, half-size screws have half area. ofc I totally agree that 1 screw is harder to cavitate due to blade tip speed E: Thing is, cavitation is not so much dependent on screw area as on tip speed, that has a tendency to create low pressure spots... This just got me a crazy idea... what if you fitted your sub with a huge screw to maximise area relative to tip speed... like wider than your boat
