Why somebody has drawn that figure to the ice? And the writing about the mysterious EM-drive of NASA.

Maybe this is one of the consequences, and that does mean anything, but the image, that is drawn in the ice does look like one of the concept aircraft, which is introduced on the Internet as some kind of study project. So, in my opinion, this image seems like some kind of aerial vehicle, and it is made in purpose.

Are the children made it, and what is the reason, why they have done that kind of thing? Maybe this is only a game, and there is nothing to hide in this case, but those kinds of things are really interesting. Those things are interesting for me, and that's why I took this image. But let's go to think another mysterious thing, what is called as "EM"-drive.

The EM-drive (1)

The idea of "EM-drive".  The idea is to connect the other propellant to the photon rocket. The photons of the photon rocket can be replaced by using some other electromagnetic radiation, like radio- or microwaves. That would allow using another propellant with the photon or some other radiological rocket motor. In this case, the system would boil the propellant and that thing will increase thrust at the lower speed.

Electromagnetic or EM-drive has the same idea with photon motor and the thing is that every kind of electromagnetic radiation has the thrust. But the power of thrust is so weak, that we should accelerate the spacecraft near the speed of light if we would want to use photons as the propellant. That means that the photons would accelerate the craft just in the last period when the craft would reach the speed of 90-99% of the speed of light by using an antimatter drive or something like that.

Only photons can have a specific impulse of the speed of light, but the thrust of the photon rocket is so weak, that the acceleration of the rocket to the near the speed of the light must be done by using some other method. And the photon rocket is an only known system, which can reach the speed, which is near the speed of the light because the rocket cannot cross the speed of the particles, which is going backward.

Of course, there are things like WARP, which are researched, but the thing is that those things are radical, and the only thing, that can send the particles backward by the speed of the light would be photon or radio wave-based rocket motor. And this is the thing, what makes EM-drive so radical.

If we would use microwaves in the EM-drive that thing could use also another propellant like water or hydrogen for giving extra thrust. That thing would make possible to accelerate the speed of the spacecraft also by using some other propellant, and then the craft would be pushed to the speed of light by using micro- or radio waves.
