What kind of spaceships would the aliens use, if they want to observe us, or we if we want to observe them?

At above the text is the artist David Hardy's vision of the "asteroid Ark", and that kind of spacecraft can be used for observing another civilization in the distant future. Or maybe they are using this kind of stealth-spacecraft for observing the human race on the earth. This kind of spacecraft what is hollowed empty, and then equipped with motors might use for intelligence operations for observing another civilization when the human race will travel to the stars in the distant future.


There have been talking about the asteroid, what is from another star, and going straight thru our solar system. And of course, some people have mentioned, that this asteroid might be the alien spacecraft. This is the thing, what many philosopher and engineer have thought. What kind of spacecraft will the aliens use, if they want to observe another civilization? This question can turn the way, that what kind of spacecraft will the human race use, when we want to observe somebody else?


When we are talking about SETI-program and making contact with another civilization, we must realize, that if the contact maker will come from another star system, must this opponent realize, that it needs the real information of the civilization, what it might want to observe. This is the only way to find out if that fictional interstellar traveler is able to make the contact with another civilization. The reason for observation is that the traveler must be sure, that the opponent is not traitorous, and want to steal or hijack their spaceship.

So the alien might want to use STEALTH-ship in this action. The production of the invincible spacecraft in the space is quite difficult. There is gravity field around every object in the universe, and it will pull the dust around them. But there is one very good way to product the stealth spaceship, what doesn't noticed very easily. This is just putting the motors in the hollow asteroid. The telescopes can't see that the asteroid is actually the spacecraft, what mission is to observe another civilization.
