Do you know? The DNA in the human body is stretches to 73 round trips to the Sun from the Earth!

Photonic Propulsion

Hey there! Thanks for tuning with TMC.

It's has been long since I last posted! anyways I am back again with this mind blowing post!
So here's a brief description: ever thought of reaching 1/4 the speed of light? NO, right??! well it might be possible in the near future!

It may sound like a Science Fiction, right? but wait! , don't you think everything we see around us was once a Sci-Fi? The computers , the Internet all those gadgets and the most important of all - ELECTRICITY, which is like the boss of everything.Okay , let's get back to the point.

So, what is PHOTONIC PROPULSION ?  The term sounds like a  photon driven launching system i.e. a mechanism in which the momentum of photons would be used to drive spaceships and rovers through the sea of space  (I will come back to this later) . You might think what the hell am I saying , that's what is , the principle behind such a propulsion system is to reduce the time taken to travel through space and to make the space programs more money efficient. Currently it costs about $10,000 to transport 1kg of anything to LEO( Low Earth Orbit). And around 95% of this cost is of just fuel! , so if we could find a way to eliminate chemical propulsion which requires fuel we could cut down the costs of space missions by a huge amount.

For such a propulsion system we need to build a laser that  could is so powerful that it can accelerate a spacecraft attached to a space sail. The laser should be 10 km wide on each side! and it would require a highly productive solar cell that could trigger the light beam. The space-sail too has its own terms and conditions! it says that it will exist only if it is around 1 micron(1/10000 of a millimetre!!) also it should be strong enough to withstand the fast and furious motion of the spacecraft.

So for now that's it, I will get back to this topic again because needs so much discussion! till then tell me what do you think about such a revolutionising idea that could change the way we used to sail through the universe!!
