This thread is meant to explain and discuss why stealth technology does not work in space on the whole, as it does underwater or in Earth like atmosphere via various methods. It will also debunk claims by scifi shows such as that 'powering down' will make you appear as drifting space junk in a debris field to avoid being caught by the fuzz. It will also discuss alternative methods to use, all flawed however.
We are detecting them over time. The asteroids would be the same temperature as space I would presume seeing as they have no power plant and have been floating there for billions of years, or perhaps those asteroids in between the sun and Earth atm are blocked out by its radiance. And I'm not talking about stealth in atmosphere, I'm talking about space. Of course stealth in atmosphere works, we see it works very well, but it itself is not undetectable. Space is very different.
The longer it takes you to reach your target, even as a drifting chunk of rock, the more chances you will be detected. If you plan to reach your target quickly, relatively at least, you need propulsion, which can be detected.
And a craft operating in space is very different.
Your picking at straws here, the article is meant to be taken in as a whole, other wise one can say you can achieve stealth via one means when the next paragraph down explains why you cannot use that method itself.
Radios are not the one and only problem, it is part of the article not the entire basis the article expounds on a variety of methods. However if you want to communicate you most likely going to use a radio unless some other method presents itself, and if you use it your sending out a signal, which can be detected. And I would also conclude that the power source for your electronics would show up your vessel quite nicely against the background of space, along with the propulsion.
By space has no temperature I mean almost anything is hotter.
Doesn't matter, the engine burn could be detected from AU's away and a trajectory potentially calculated. If you fire again to change course, you can be seen again. And again, the heat of the probes energy source will show up like 'the red dot ' on a white casmir sweater.russ_watters said:I guess it depends on the specifics of the motion -- probes launched these days go months or years between engine burns.
russ_watters said:"Easily"? No. Again, if such other methods worked well, we would already have found every asteroid in our vicinity instead of being surprised when mountain-sized asteroids pass nearby. Not to mention our stealth bombers and fighters would be a waste of money.

Again, atmospheric stealth is not perfect. http://www.telegraph.co.uk/news/ukn...lephone-masts-can-detect-stealth-bombers.htmlLike they've done against stealth in the atmosphere...?

I see a lot of problems with the article. One glaring example:
Our stealth aircraft have an ingenious method of making their radios undetectable: they turn them off.

Yes, they are the payload. They are inert projectiles.mfb said:Yes but they do not have payload on their own.
I explained this already, firing them, whether chemically or electromagnetically, will cause potential detection. The projectiles will carry residual heat from the firing process. The chemical explosive will cause a heat bloom out of the barrel. A rail gun needs power, and therefore a power plant.mfb said:What would heat them?
By space has no temperature I mean almost anything is hotter.
Relative to energy weapons in particular. And yes there is a limit to speed in space, C. In order to reach relativistic velocities with projectiles, you are going to need a massively long coil gun with many many segments and a lot of power.mfb said:Slower relative to what?
There are no absolute speeds in space.
Your missing the point, the question is not about the speed of anything in this matter. Its about detection.mfb said:A slow projectile relative to its source can be fast relative to its target.
Right, and detection does not necessarily = defense. It is a stage of defense, but not a pure defense. If you were tied and chained to a railway and felt the train coming that means you detected it, but can you do anything about it?mfb said:Right, but we were discussing detection to defend against it.
