[USA, Cape Koneveral = Joint Reporting Report, USA] With long-term goals such as rare resources harvesting, countries around the world are exploring space exploration. It is a great opportunity for Korea with a willingness to expand.
Lee Sang-ryul, Director of the Korea Aerospace Research Institute, is an acid witness of Korea's space exploration research that drafted the 2008 Dal probe development. He served as the head of the moon exploration business and wrestled with the shortage of fuel shortages and found a breakthrough.
On the 5th, when Danuri was successfully launched, Lee met with a joint reporter at the Cape Koneverall launch site in the United States. He said, The universe area of the Republic of Korea will be expanded until the moon, 380,000 kilometers away from Earth.
The following is a question and answer with the director.
Q. What is the sense of success in Danuri?
A. You can have taken the first step toward the moon. There is a long journey to fly about four and a half months by the month. As designed with the trajectory fertilization maneuver, it must go beyond the gateway to enter the moon track. In addition, it is operated in the moon orbit for more than one year, and all six mounts are fully successful to achieve their goals.
However, it is expected that the Korea's first moon exploration mission will be successfully performed as the coincidence has been focused on research and development.
Then, Korea becomes the seventh moon exploration in the world. In the meantime, domestic space development has been around 600 km of orbit and orbit about 36,000 km, but through this mission, the space area of Korea will be expanded to the month of about 380,000 km away from the earth.
Q. Is the BLT orbit a rare flight trajectory?
A. This is the first time that Korea flies out of the earth's orbit. The BLT trajectory is not a normal orbit. It was an inevitable trajectory because it was inevitably selected because it had to save the fuel, but it was a considerable adventure and burden to calculate the flight of this distance in space as the maximum flight distance reached about 6 million kilometers.
Researchers discussed the night, meeting, calculating, and again. The first BLT trajectory design took seven months. At that time, I really suffered a lot. The result was successful as much as I tried. From the US Aerospace Office (NASA), 'It has achieved great achievements in this field. There is no part to be modified because it is very good. ' Since then, it took about two years to design the final trajectory design, including the trajectory.
In the process of going to the moon, the operation and inspection for normal operation, such as solar panels and antenna deployment, will be performed and modified up to nine trajectory for about four and a half months. It's the first time to try, but I expect successful results because the accumulated satellite technology has been concentrated.
Q. What is the meaning of cooperation with NASA in the United States?
A. NASA's shadow cam was installed through an international agreement with the United States. We carry shadow cam, and NASA provides Danuri's satellite data through the Shim Woo-ji-guk, which can communicate with Danuri.
Collaboration with these space powers is an important shortcut to the Shimwoo Exploration Bureau, which departs late like us. This is because it is an opportunity to secure a lot of technology in a short time.
In addition, this project will expand the opportunity to participate closely with the Artemis Project, the US manned space exploration plan. It was a great opportunity for Korea with the first step into space exploration and willingly expand in the future.
Q. In addition to Korea, there is a country that conducts the moon exploration this year. Why is the moon exploration again in the spotlight?
A. This year, not only Korea, but also India, Japan, and the United Arab Emirates are preparing to launch the moon probe. According to the US Strategic International Study Institute (CSIS), 106 lunar orbits and moon-related projects are currently underway in 19 countries and European space (ESA).
Fifty years ago, the moon exploration was one-time and the final goal was. But now, in the moon, it is changing to a goal that can continue to build a base where humans can stay long-term and mining resources.
In particular, as the existence of water was confirmed in the moon's Antarctica, the value of the moon was even greater. This is because it can not only obtain drinking water from the moon, but also decompose water to produce oxygen and hydrogen, use it for survival, and use it as a fuel such as a rocket to go to a farther planet such as Mars.
There are only dozens of rare resources that have been revealed in the moon. Among them are helium 3 and rare earths. Unlike the earth, which is protected by the solar wind due to a thick atmosphere and a powerful magnetic field, it is estimated that there will be a helium 3, which is about 1.1 million tons of helium. Rare earth is essential for manufacturing electronics such as smartphones, electric vehicles, and TVs, but it is a strategic resource with limited production sites on Earth.
Q. How is the moon landing plan ready?
A. The goal is to launch the moon lander as our projectile by 2031. Currently, it is promoting the mission and design of the moon lander.
The development of the next-generation projectile to send a lander to the moon should also be promoted. The next-generation projectile plans to develop a two-stage projectile with five 100t-class engines and two 10t engines. A total of 1.9 trillion won is expected to be invested by 2031. Preliminary feasibility studies are currently underway, and if they pass, they will begin in earnest from 2024. The next-generation projectile can shoot a 1.8t moon probe.
