Could you detect a stealth aircraft like B2 or F117 if it's dumb enough to fly directly in front of radar dish at close range? (as much as it basically blocks the entire scanning beam emitted from that radar) If it's so, does it mean the "stealth" part only effective at long range radar scan?

Does a spacecraft DeltaV change vector is affected by the direction of the nozzle or the direction of gas that's expelled from that nozzle? I mean, if we outfit the spacecraft engine nozzle with target-type thrust reverser, the moment the thrust reverser deflector doors deployed, the thrust reversal (theoretically) takes effect and the doors block the expelled gas in the end of the engine. In this case the gas passes through the inner surface and travels frontward to provide force opposite to the heading of the spacecraft. Assuming the spacecraft is on stable orbit, should the craft:
A. DeltaV increases (velocity change in respect of gas expelled from nozzle)
B. DeltaV decreases (velocity change in respect of gas deflected frontward)
C. No change (velocity change of nozzle gas is counteracted by deflected gas)
Assume the reverser able to reverse 100% of gas from the nozzle, which one is going to happen?

I have a space elevator design, but I haven't test it due to the insufficient performance of my computer. It is unable to transport stuff from ground level to orbit, but still able to launch rocket from it's summit (I haven't tested how it behaves though). Here's what I've planned:
1. This plan requires Physics range extender mod. Also, Extraplanetary launch pad mod (build rockets on another celestial body by using on-site mining). It takes the advantage of the ore mining feature for building rockets. Additionally it also requires Vessel mover mod (move and spawn vessel-in game) if the elevator is going to be placed elsewhere (even on another planet). This last one is optional, though without it, it's restricted to default runway or launch pad
2. The plan uses the exploit that fairings can be built infinitely long and it will act as a single rigid entity (no structural instability on fairing no matter how large and how long it is). The elevator is divided into 3 components: ground level, connecting tether and orbital facility
3. The ground level consists of a series of drills, batteries, radiators, ore tanks, anything required for mining operation. This will be the main ore mining facility for building rockets on the elevator's summit. On the top of the ground level facility, is a fairing that extends all the way beyond the atmosphere. To keep the whole thing stable, the launch clamps are attached on the fairing, not the ground facility (the facility hangs under the fairing, mining ore while the fairing itself is supported by launch clamps)
4. The connecting tether is a fairing that extends all the way beyond kerbin's atmosphere (70km high). I haven't found a way to directly edit the fairing length by simply typing the number instead of building it manually (which is time consuming), but an extremely long fairing is a rigid structure that counts as a single entity, making it very good for long structural element
5. The orbital facility consists of habitation modules, solar arrays, labs, comms array and stuff that you would attach to space stations. It must be symmetrical to keep whole thing balanced. It provides power for ground level facility and also houses the manufacturing module of extraplanetary launch pad and it's spawn point on top center. Basically, since the whole elevator counted as a single craft, the elevator works by mining the resource on ground level, then using it to build rockets that spawns at orbital facility (so in essence, while it's unable to send stuff physically from the ground, it does send the resource mined from the ground to be used on the orbit)
Feel free to comment about it

If we compare between medieval-era cannon (On the variety that can be towed around like WW2 PaKs AT gun, using spherical cannonball roughly the size of softball) against modern anti-material rifle (assuming the caliber is 12.7 mm, pointy round), shooting at target 100 meters away, assuming the shot hits the target dead-on, will the size and mass of spherical (non-pointy) shape of cannonball compensates for it's low velocity and focused impact of modern rounds?

For nuclear thermal plasma jet rocket concept, first, we need to evaluate the feasibility of nuclear engine itself. Nuclear propulsion for aircraft has already tested during cold war by US and USSR using their nuclear aircraft program, with the aim to create a strategic bomber using the very air itself as propellant for unmatched operational range. Both program didn't have a promising result, with different reason from each side.
For US, the main problem is the crew shielding, since a nuclear reactor and associated equipment for cooling and radiation shielding is very heavy, greatly limiting the bomb load capacity, and also reducing it's maximum speed. Another is the maintenance problem since the maintenance of nuclear engines are very demanding compared to normal aircraft engine. USSR managed to get away with the issue of radiation shielding by shielding the crew instead of the reactor, but this makes the aircraft much more radioactive than US, and thus requires regular decontamination operation to keep it usable. I've written an article about this maintenance difficulties in this forum, please take a look (it's a very interesting read):
Ultimately, the programs did not produce a promising result as the shielding and maintenance problems plagued the prototypes, and once the practical ICBM came into service, the operational range of nuclear aircraft becomes a moot point since it does not justify the environmental disaster the nuclear aircraft caused if it's shot down as well as placing the crew at risk during the mission just to send a couple of nuclear bombs compared to ICBM method. With the reasons above, both projects are scrapped. As such, the full potential of nuclear aircraft itself is still not fully understood yet

In Disney's Atlantis: The Lost Empire, the movie features the Ulysses, a Steampunk submarine the size of roughy two aircraft carriers that can dive as deep as the Mid-Atlantic Ridge. In real life, a submarine of that size cannot dive that deep because the high pressure underwater would cause their hulls to implode (The bigger the ship, the more pressure it has to deal with). The Ulysses would have trouble getting even that deep because its steampunk engine would consume all interior oxygen if it dove underwater, and as a result the crew would all die of asphyxiation. Real-life diesel submarines exist, but ordinarily they can only use their diesel engines at or near the surface where they use a snorkel to draw in air. For completely submerged operation, most submarines use electric engines powered by batteries, but this greatly limits their submerged range
Another one is from Waterworld, who manages to multiply the stupidity, by having a fore-and-aft rigged Trimaran that is powered by wind so reliable the main character felt it wise to build a giant wind turbine on his mast. God only knows what would happen if the wind ever went slack and the sail slumped back into the turbine.
Yet another one from The Hunt for Red October: During one scene a torpedo is dropped by a helicopter on a submarine, but then remotely detonated by the helicopter's mothership prior to impact in order to fake the destruction of the sub. This is in reality impossible. The torpedo depicted in the movie is a US Mk 46, and once you have put one in the water (assuming it's working correctly) it will search for and then chase after its target until it either detonates or runs out of fuel. The film also portrays the caterpillar drive as making the submarine ultra-quiet because the propellor isn't moving. In reality a nuclear submarine's biggest noise source are the cooling pumps on the reactor. Real life diesel-electric sub is far quieter because they can totally shut down everything onboard for total stealth, with the tradeoff being a reduced underwater operating duration, unlike on nuclear sub, where you had to run the cooling pumps for the reactor to keep it cooled or risk of turning it into molten slag

In preparation of upcoming Breaking Ground DLC, a variety of exploration vehicle is being tested. This one is a massive flying base, The Flying Fox, equipped with science lab, crew quarters, and cargo bay for rovers. It's intended to go to faraway places and unpacked into a science base once it's landed, and can be repacked again to fly into another destination
Another one is a two-man exploration craft, The Buzzing Mosquito is a tiny jet equipped with nuclear thermal jet, giving it infinite range, perfect for those science contracts
And the last, one of the fish in the ocean is unlike the others... The Albacore is a two-man submersible suited for underwater exploration and science

Aside from them taking issue with the term "dark side" (I have no issue with it, as long as you understand what we mean by it), I think, given enough lead time, they'd get a probe up there to watch. Without enough lead time, not much.
Yeah I know that the term "Dark side" is rather incorrect compared to "Far side" (Since that side still receives sunlight). Anyway, the last time there's a large-scale event involving impact on celestial body in solar system is during Shoemaker-Levy-9 comet impact with Jupiter. My next question is, what kind of scientific data that can be gained from observing impacts? Just curious

If there's an asteroid detected on collision course not on earth, but the dark side of the moon (with the debris small enough to not pose a hazard on earth reentry, basically a spectacle), how the world's scientific community will react?

Want to send a message to the whole Earth that you're awesomely powerful, and probably egotistic and evil, too? Just fire up your biggest space laser cannon or longest-range missiles and use them to deface the Moon by blasting your face or INSERT YOUR MESSAGE HERE onto it. After all, the Moon has no weather or pesky tourists to mess it up... so any mark left on it, even if it's just etched into the dust, will probably remain there until the Moon itself is destroyed. Your message will be set in stone, pardon the cliché. It doesn't have to be the Moon. Any sufficiently large and prominent landmark will do. In a pinch, you can use graffiti, as long as it's large graffiti; but lasers, or missiles carving are more stylish. The next logical would be stating your demand to humanity. If they refuse, blow up a chunk of the moon to "persuade" them

Made 2 new mini-submarine
This one is a prototype for mini-sub with much more powerful engine
It's succesfully tested, but tests shows that it's incredibly difficult to control because it's engine is too powerful. It's currently being redesigned, no name has been given yet
________________________________________________________________________________________________________________________________
The second one is a mini-sub with 2 crew capacity, officially named "Big Tadpole"
It's 50% more expensive than Little Tadpole and more complex, but offers more crew capacity, faster speed and more maneuverability. How maneuverable? From this...
To this...

Made an improved version of my observation aircraft. Now it becomes even more bulbous than before
Some changes includes the modifications to tail assembly, different engine, and tweaking the wings' positions
Four nuclear thermal engine allows it to fly indefinitely, befitting it's role as an observation aircraft to reach faraway places
Due to it's extremely bulbous appearance, it's officialy named "Swollen Tick"

Interesting topic here. Personally, in terms of spaceship design, I prefer functionality over aesthetic. A research ship might be nothing more than centrifugal habitation pod with sensors and gizmos sticking out of the hull. An interplanetary relay is nothing more than a radar dish with thrusters, a space gun is literally just a gun with thrusters around it. It seems appealing to me when the spaceship is nothing more than a necessary life support components, habitation pods, thrusters and a variety of junk bolted around it
