Yes, if the rocket exhaust velocity is comparable to the escape velocity then the thrust is lost. The Moon now has more atmosphere than it did in the 1950's because the various spacecraft that have visited the moon have added some gas.

Black holes have no upper limit on how much mass they can suck in. There is a problem with how quickly they can suck matter in, if you dump too much matter into black holes at a time it squirts some back out before it reaches the event horizon.

Actually, as a black hole's mass goes up the event horizon radius increases linearly, but the volume goes up by the cube of the radius. So, as you throw more and more matter into a black hole its effective density (based on the event horizon) goes down. Black holes that are billions of solar masses would have a density roughly equivalent to that of air.

You missed something: To deorbit a moon, you would need a shitload of fuel. However, this fuel isn't just present there - it has mass of it's own. In fact, in order to move a moon using fuel, you would have to move the whole system of that moon, fuel, fuel tanks and engines - all adding up to whole mass counter. That means you would need MUCH more fuel to move the moon AND itself, along with tanks and engines, and adding a single engine would mean adding more fuel, because engines, of course, have mass, too. There is another thing, however. By adding so much shit onto the moon, you would greatly increase it's mass, therefore it's gravity. It may be even enough to cancel the orbit and make the moon crash straight into the planet! Who knows? Calculations have to be done.

So you can't deorbit a moon in the game because of game mechanics, but it would be possible in real life yes? In theory at least. If a moon was hit by a rouge planet or a huge comet/asteroid from the right angle, wouldn't that possibly deorbit the moon? Even if it shatters the moon, the force might be enough to slow down the pieces enough for them to rain down on the planet.
@cylelangenhennig6242
@cylelangenhennig6242 10 жыл бұрын
According to my physics class, if something shatters mid-flight, all the pieces will spread out, but if you averaged their distances and masses, the center of mass would still be on the same trajectory. Some pieces might get thrown off track enough to enter the atmosphere or become ejected, but the majority of them will remain in orbit. For something as large as the moon, they would probably eventually come back together due to gravity!
@LarsaXL
@LarsaXL 10 жыл бұрын
But if a moon ran into something of rougly equal mass in a head on collision, wouldn't that slow it down to near standstill? I agree that most impacts would leave what was left of the moon in orbit and it would probably pull itself back into shape eventually. Since orbit needs velocity, slowing an object down puts it in a lower orbit. If a celestial body had no velocity, then the strongest force of gravity (In a moons case, the planet it used to orbit) would just pull the object in a straight line. I agree that this is an extremely unlikely scenario, but it is a big universe and it is not impossible that something like this has happened or will happen. An impact from a large body on a moon could alter the mass of the moon significantly which would, if not totally deorbit it, then at least change its orbit distance.
@cylelangenhennig6242
@cylelangenhennig6242 10 жыл бұрын
Yes it is unlikely, but you're right. If something with equal kinetic energy (could be something less massive but moving much quicker, or equal mass and speed) hit the moon from the opposite direction, it would stop in it's tracks. It might break up a little bit, but some LARGE pieces would fall straight down to earth and would likely destroy all life, if not the entire planet. I could imagine something of that size striking the earth could break up the crust and smash it down into the mantle or something crazy like that!!
@LarsaXL
@LarsaXL 10 жыл бұрын
Let's hope that never happens. And if it does, lets hope it happens to some other planet with no life on it, but still close enough for us to observe. Though any kind of impact on the moon would slightly alter the orbit by adding more mass, or making a small change in velocity. I think. Just like everytime a meteor strikes earth, it adds to the earths mass and gravitational pull by a very small ammount.

Patrick Sparks That is how it works but if i need to explain i will. The amount of force our mythical explosion has is incomprehensible and since moons aren't exactly designed to withstand such forces (after all they're mostly composed of rocks so its not that tough) you will break the moon apart before the explosion can apply all of its force. Picture this: You swing a baseball bat at a pane of glass. The glass breaks and the shards go flying. If you hit the glass 10X harder than that the shards don't really go much farther because most of the force of the swing is wasted due to the glass breaking. It's the same thing with our explosion. Most of the force is wasted because it doesn't hit anything once the moon starts breaking. Making the explosion more powerful won't really help because you will break the moon even more. If the moon were indestructible you might be able to make it work but otherwise, no way. If you still want to argue I will be happy to debate with you.

Based on those numbers, though, it COULD be possible if they were to include an engine that was basically a miniature nuclear weapon with its blast zone somehow reduced to a tiny force trajectory... the Tsar Bomb produced 210 petajoules (that's QUADRILLIONS of Newtons per meter) with a weight of only 27,000 kg (admittedly packed into a tight 8 X 2 meter missile) If that energy could be focused into a single lateral direction, it would be TOTALLY plausible to de-orbit a minor celestial body like a moon.

This sounds like a project for SWDennis. He tends to like using mods that let him scale up part sizes by ridiculous factors. Using those mods (and whatever joint modifying mods he uses) you could probably make a ridiculous enough engine to de-orbit a moon if it weren't on rails.

Scott, try landing on Gilly with 3 Mainsails, and 4500 kiloNewtons of thrust. Try to make the rest of the ship as light as possible, and you must use the engines in "Bursts" so you use action groups to turn on the engines and keep it on full throttle. You must also use mainsails for interplanetary injection and return. dropping stages are okay
