Humanity continues to search for the meaning of its existence by finding ways to travel through the stars.
Space is the final frontier of man. Unfortunately, it has already been more than 30 years since man walked the surface of the moon. For now, all we can do is to speculate and plan in going to Marks. But that’s still better than no plan at all. The blueprint for travelling to other planets, and possibly even through different star systems is still being developed.
In order for humanity to efficiently travel through the cosmos, we first need to find ways in cutting a significant amount of travel time. With this, a highly effective and reliable propulsion system is needed. There are already a few principles and experimental systems that are under development.
Here are some of the most notable ones:
Utilizing Antimatter Particles
For now, particle accelerators are the only ones that can create antimatter. The amount that is created is also too miniscule for it to be usable. A revolutionary technology should first come up for this to happen. It should also be capable of making more antimatter, and then in no time, we’ll be out in the stars searching for new world.
Fusion power is a very reliable propulsion system as it will enable starships to have a seeming infinite source of energy. Unfortunately, scientists are still unable to develop a fusion powered propulsion system that works. This is because controlling the detonation of a series of small fusion bomb explosions is very hard. Our current international nuclear test bans also prohibit it.
In a plasma-powered propulsion system, electrical and magnetic currents are the ones that produce thrust. This is done by accelerating the charged particles in the system. The Ad Astra Rocket Company is pioneering its development. But as of now, everything is still in its experimental stage.
Using Solar Sails
Solar sails are considered to be the most suggested propulsion system for interstellar travel. This catches light particles from the sun to propel it forward. The principle is to have a big-enough solar sail that is capable of catching large amounts of photons. This would then be enough to give thrust to the spaceship without using any fuel.
Final Thoughts on Interstellar Travel
With all of these being said, it is evident that humanity is on the right path. However, the efforts with these experimental systems should be doubled or even tripled. Hopefully, it gets the right funding from the various governments around the world. This is humanity’s only hope for its long-term survival.
