Unveiling the Future of Space Exploration: Innovations in Solar Sailing with Carbon Nanotubes
First Things First: Story of How are We Going That Looooooong Road to Space
Behold, the audacious spectacle of humanity employing colossal contraptions, the mighty rockets, to transcend the very boundaries of Earth! These “mammoth marvels” demand even more colossal fuel tanks to conquer escape velocity (this is a term in physics which is used to explain the necessary velocity in order to escape from the gravitational attraction). Sometimes we change the fuel to have more efficiency but even by changing it, still we have a BIG fuel tank problem. Because we cannot store enough fuel on rockets to travel interplanetary. Thus, we are currently developing new alternative technologies like electrical combustion or spin launch but they cannot be enough to reach enough speed with small amounts of energy.
Since, in the quest for exploring the vastness of outer space, one major obstacle that scientists and engineers face is the issue of fuel consumption. Traditional space missions heavily rely on conventional fuels, such as liquid hydrogen, to achieve the necessary speed and escape Earth’s orbit. However, this reliance on fuel poses significant challenges when it comes to interplanetary travel.
Think, how beatiful can it be if we have another alternative that can solve these problems. Wait! WE HAVE…
“O Captain, my Captain!” Walt Whitman metophorically says to call his ship, to call his captain. People were sailing through the eternal oceans and seas back then. When we found the end of them, we started to think beyond the limits we see. In addition, humanity loves to use it’s old methods for brand new areas such as space. So, there comes a “magical” part with the space sailing concept. Especially, when CNTs integrate to the solar sails, they add more emission and efficiency to the magic.
Why Ought We Embrace Solar Sailing’s Noble Course?
The limited capacity of spacecrafts to carry fuel becomes a major hindrance in their ability to reach higher speeds and cover longer distances. A large portion of the fuel is consumed during the escape from Earth’s gravitational pull, leaving little room for additional fuel that could be used for propulsion in outer space.
In an era of burgeoning possibilities, where the realms of science and technology converge, the arcane yet promising art of solar sailing, emboldened by the integration of carbon nanotubes, stands as a beacon of innovation. As we delve into this captivating journey, we shall unearth the intricate synergy between advanced materials and celestial propulsion, ushering in a new dawn of space exploration. Join me as we embark on a voyage to fathom the profound significance of these pioneering developments, illuminating the path to the future of cosmic exploration.
Wait, What is Solar Sailing Actually?
Think of a GIANT blue kite and you are flying it in a very windy day. It will rise and move untill the wind stops. It can even go vertically up or down if you let it to do. So, what if your giant blue kite has no rope and it starts to go up. It will pass through the atmosphere (yes, our kite is fireproof) and eventually it will not stop because there is nothing that can obstruct it by friction. Moreover, we can make our wind by using laser to direct it on the way we want. Unfortunately we have come to the end of our kite’s story. It is time to dive in SOLAR SAILS story. Kites have a lot in common with solar sails in moving principals. Luckily, solar sails do not need wind to fly!
Recent History of Space Sailing Theory
Space sailing (or solar sailing) was a theory when it was started to have been worked on at the beginning. The idea was belonging to the Johannes Kepler at first. His observations on comets which were leaving their star trails around the Sun. Then, James Clerk Maxwell’s electromagnetic fields theory proved the light(photon) pressure concept. Moreover, this concept became a topic for science fiction books as well. Arthur C. Clarke, wrote the “Sunjammer”, a short story about race between solar sails which use radiation pressure.
The theory became reality in 2006 when NASA’s Glenn Research Center actually prepared a solar sail-NanoSailD. This solar sail launched succesfully to the Earth orbit in 2011. This mission showed that solar sail technology can measure and collect data faster and more accurate. Another benefit of using solar sail is, getting rid of nearly 8000 pieces of space debris caused by launch. Basically, solar sailing have good impacts on not only after launching process but also launching process itself.
Space Sailing is changing the rules for exploring the space. In basic terms, spaceship uses the electrophotonic particles and photons from solar winds or Earth’s surface. This new method unlocks the potential for interplanetery missions to be faster and to have lower costs from alternative space travel methods. Solar sails have extended sails which capture the momentum of light from source. One of good things of solar sailing is, the “source” can be a concentrated laser based on Earth or they can use stars’ -mostly Sun’s for us- light. Solar sails utilize sunlight as a means of propulsion, harnessing the energy from photons emitted by the Sun. By deploying large reflective sails that capture and reflect sunlight, spacecrafts can generate thrust without relying solely on traditional fuels.
Solar sails offer several advantages over conventional propulsion systems. They eliminate the need for carrying excessive amounts of fuel, enabling spacecrafts to travel longer distances with greater efficiency. Additionally, solar sails provide continuous acceleration as long as they are exposed to sunlight, allowing for gradual but steady increases in speed over time.
