The moon is one of the largest natural satellite in the solar system, with a quarter of the diameter of the Earth.
As small as it is, gravity is also smaller than Earth. The moon's gravity is only one-sixth of the Earth, so a person weighing 60 kilograms on Earth is only 10 kilograms when he goes to the moon. The acceleration due to gravity is also small, increasing the speed by 9.8 meters per second when an object falls to the ground on Earth, but by about 1.6 meters per second on the moon. Because of this, even the same object falls six times slower than the Earth. Therefore, if you jump in place from the moon, you can jump higher and fall more slowly. If you look at the video taken from the moon by the astronauts of the Apollo program, you can see the balloon jumping up and going down slowly like a little bit.
There is no atmosphere on the moon. Because gravity is small, the moon cannot hold the gaseous molecule that forms the atmosphere. So there is no sound or wind on the moon. Sound needs a "Medium" with molecules that can transmit energy, such as air, water, and metal. However, no atmosphere on the surface of the moon acts as a medium, so no sound can be heard. There is no air to move, so there is no wind.
As such, the moon's environment is very harsh for life So why do people continue to study and explore the moon? The most fundamental reason is curiosity. The moon was a grateful lighthouse that lit up the night path for mankind for many years and a frightening mystery. But the moon exploration is too huge to be driven only out of curiosity. The reason why advanced countries invest huge budgets, the latest technologies and manpower in lunar exploration is because, above all, exploration of the moon is a matter of pride in science and technology. To get to the moon, you must have good performance Launch Vehicles, the latest technology must be applied to help you live safely in space, and the ability to calculate accurately moving long distances.
In a word, lunar exploration is a "Comprehensive art" that combines all the science and technology of a country. Therefore, success in exploring the moon is a testament to how high the country's science and technology are.
I am working on building the Lunar Space Elevator Infrastructure.
I'm not an expert, but I don't think this is an absurd plan. All the little things that go into the artwork combine to create a masterpiece. Pay attention to our plan and join in, it will be all material.
A New Intern at LiftPort
Hello, I am Byungik Jung. I am working as an intern at LiftPort. I majored in aviation information and communication engineering. After graduating from Kyungwoon university, I worked at the Korean Air Command Center as a Network operator. I maintained and monitoring Korean Airline communication network equipment like Router, Switch, VPN monitoring network performance, resolve technical issues. I am participating in the WEST program which is an International Education Exchange program in Korea. The WEST (Work, English Study, Travel) program is a Government-funded overseas program to support university students(youth).
My goal is to develop my core competency and global insight through language and internship training in the U.S.
I started working here after two months of language training in San Diego, CA. It's only been a week, so both Tacoma and LiftPort are still unfamiliar to me. However, LiftPort’s leader Michael is helping me adapt to the LiftPort and Tacoma quickly. In the first week at LiftPort, I spent time adjusting to the new environment and making plans. In the meantime, I studied how to use the project management program "Smartsheet" and took classes through Webinar. The most impressive activity was getting an overview of LiftPort's various activities directly from Michael. For example, I've learned a lot about the process and goals of the projects, the systems we're building at EML-1 points, the role of satellites, and so on. I can't wait to do some works at the aerospace company. I will do my best to improve my company's project.
My fixed task is to post a blog every week. I want to create a variety of interesting blogs and get people interested in aerospace. I think this is our goal and a way to promote our project more widely.
I am going to post the blogs every week because we are finding someone who is having the same plans with us, and will change the world. I think this is important work for our projects. I'm so happy to take this important role.
