Recently in science, we are studying about astronomy, and us humans have made great scientific discoveries of space. But many of us might wonder, ‘why do we we explore space?’ By learning the whole reason of why us humans explore space, would lead to a better understanding of our galaxy and the universe surrounding us.
The reason why we explore space is pretty simple. It is because us humans are ambitious and curious about the unknown space, we push ourselves to boundaries, and breaking them, creating new technology that would let us continue exploring further. As NASA agrees, “Humans are driven to explore the unknown, discover new worlds, push the boundaries of our scientific and technical limits, and then push further.” It is human nature to be curious and explore something we don’t know, and because of these curiosity and ambitiousness, it has affected our planet by advancing the technology and have provided us many benefits. And of course, these explorations have brought in new knowledge and ideas of space.
When NASA has started exploring the space, they were challenged to create an advance systems and technology to be able to explore beyond the low-Earth orbit, and extend their discoveries to translunar space, near-earth asteroids and mars. Low-earth orbit is an orbit that extends from earth’s surface at sea level to an altitude of 400 and 1000 miles. It is a satellite system that is used for telecommunication, and communicating datas. To overcome this challenge, they have created a International Space Station which serves as a space laboratory for human health, material research and more. It was first created as a test bed, for testing out NASA’s new technology. International Space Station are now helping the astronauts to stay healthy and fit for exploring the unknown.
Today, the some exploration has extended over to the translunar space. Translunar space is the expanse surrounding the Earth-moon system, areas extending far beyond the moon orbit. Exploring in translunar space would mean exploring outside the protection of Earth’s magnetic field, which would bring in new experiences and knowledge. Magnetic fields are the areas where an object exhibits magnetic influence. Magnetic object could be attracted or pushed away by these fields. Earth also has a magnetic field, as earth is filled with molten iron, which would push away radiations and particles such as solar wind, reducing the damage for us. Extending space exploration to translunar space could be dangerous, but it also bring benefits for us earth. As NASA states, “Operating in translunar space, NASA can research galactic cosmic radiation–potentially the most threatening element to humans exploring deep space–and develop mitigation strategies that may also lead to medical advancements on Earth.” Us humans would be able to gather new informations about the galactic cosmic radiation and reduce the damage for us humans, and possibly creating more advanced medicals. Exploring the further unknown would bring so much benefits as well as discovering what surrounds us.
The exploration not only extends to translunar space, but also to asteroids and mars. Asteroids are believed that they were formed early in our solar system’s history, possibly about 4.5 billion years ago. By studying these near-earth asteroids, it would help us discovered the materials from the solar nebula. As NASA comments that these discoveries would lead to possible answers for compelling questions such as ‘how did the solar system form and where did the Earth’s water and other organic materials such as carbon come from?’. By investigating the asteroids would not only help us understand the history of space, but also be able to predict the future impacts on earth and reduce them. Mars, are also popularly investigated by explorers and scientists. Many scientist have discovered that Mars has a similar history to Earth’s, and many are investigating if life exists beyond earth and on Mars.
One of the biggest reason why humankind are so passionate about exploring the unknown space, is due to our curiousness and our ambitions, and the new discoveries and informations about the space could be used to improve earth through technology, medical, and even connections between different countries. As NASA agrees, “Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.” Exploring space can be very dangerous, and number of explorers has died from accidents in space. Yet it affects the world environmentally and socially, affecting the world positively and improving for better. Environmentally, it would improve our planet, as more advanced technology and advance medicals are created for exploring the space, making the world more innovated and improving the environment we are surrounded by. Socially, the unknown of space would bring many scientists and explorers around the world together, sharing knowledge and ideas between them, creating a connection or a bond with different countries. Why do we explore? Not only we are curious about it, but it also bring many benefits and advantages for us.
