Korea’s first moon probe, Danuri, is ready to fly to the moon.
Danuri, who finished the final inspection ahead of the launch in August, appeared in the media at Daejeon Korea Aerospace Research Institute. The solar cell panel for supplying power and all six mountains for the moon observation have been loaded and ready.
Danuri will be transferred to Cape Koneveral Air Force Base, Florida, USA, on July 5, and will be launched on August 3 at 8:20 am (Korea time) on the Falcon 9 rocket of the American space company SpaceX.
Although the schedule may be partially adjusted depending on the site situation such as the weather, there is no special situation in the launch schedule. It was imminent when Korea went out of the atmosphere of the earth and went to another celestial body.
■ Danuri Launch Preparation Last Finish
Danuri recently completed the completion of the launch site by testing whether it can be persistent in the space environment such as cryogenic, high temperature and electromagnetic waves, and installing a surface multi-layered thin film insulation (MLI) to prevent damage caused by the rapid change in the universe. On the 2nd, the previous review meeting was completed to confirm that the launch site was possible.
Danuri satellite is currently waiting in Hang-Woo after all preparations. You can see major equipment such as the unprecedented solar cell panels, golden shadow cam, and pole cam. Researchers in the dustproof suit were diligently traveling around the satellite.
After the launch of the satellite, the satellite operation center, which collects and analyzes the data and controls the movement of the satellite, has completed the operation. On a large screen that takes up the entire wall, the number of simulations showing Danuri’s speed, position and orbital is constantly returning. After the launch of the satellite, 60 people sit in front of the monitor with a lot of people and analyze the data from the satellite and the board.
The Satellite Operation Center is linked to the 35-meter-sized Shim-sang-san Telecommunication Anthena (KDSA) installed in Yeoju to form a satellite ground system.
Kim Dae-kwan, head of the Hang Woo-yeon Dal exploration business, said, We are not only the first month exploration, but also a challenging attempt in that we have embodied high levels in small satellites.
■ Initial communication within 1 hour after launch, 4 months to enter the moon track
Danuri will depart from Hang Woo-yeon on a special container on the 5th of next month and will be transferred to the launch site at Incheon International Airport. The container originally tried to recycle what he wrote when he was transferred to Cheonrian No. 2 satellite, but he had to create a newly created Ukrainian Antonov, which could transport this large cargo in the aftermath of the Ukrainian war.
After 40 minutes of launch on August 3, Danuri is divided into sixth of the satellites in Falcon 9, followed by a solar panel. One hour later, he attempts to communicate with the Shimwoo Network antenna in Canberra, Australia. If this communication is successful, Danuri’s data begins to enter the control room of Hang Woo Yeon in earnest.
Danuri, who is out of the atmosphere, starts a 1560,000 km journey for four and a half months, aiming to settle the moon on December 16. Danuri uses a liver between planetary gravity, drawing a large trajectory, and operating a ballistic lunar transfer (BLT).
If you go to the moon along the 380,000 km straight path, you can arrive in 3-4 days, but using the BLT method can reduce fuel consumption by 25%. It was also considered that it could reduce fuel to carry other boards, and to move long distances and build flight know-how.
Danuri reaches out near the moon and reduces the speed five times and narrows the track and enters the final observation orbit. Danuri performs a monthly observation mission for one year, drawing a circular orbit that passes through the moon polar region at 100 km above the moon.
■ 6 boarding body for moon observation
Stable in the observation track, the moon exploration begins in earnest. Danuri is equipped with six high-tech observation equipment, including the permanent shaded camera ‘shadowcam’ developed by the US NASA and the high-resolution camera ‘Luti’ developed by Hang Woo-yeon.
Shadow Cam is a high-precision camera that is attracting attention because you can see the moon’s polar shadow area that has not been observed because it does not light throughout the year. It can be observed if there are water or resources in the polar area. NASA plans to use this information for the landing location of ‘Artemis Mission’, which is being promoted in 2024.
Ruti is a high-resolution camera developed by Hang Woo-yeon. It is a precision terrain observation equipment to properly shoot the surface of the moon with a different environment from the earth.
There are also gamma rays for exploration of moon surface resources and magnetic fields for studying the cause of moon creation. The Gwangsiya Polarization Camera is expected to be the first to shoot the polarizing video on the back of the moon, which can analyze the influence of the moon surface particles and spacecraft. In addition, there is a space internet installation, which will be the first opportunity to demonstrate the Internet communication.
■ Will it be a stepping stone to enter the heartworm?
Danuri performs the observation mission through the moon around 12 times a day a day. These data are shared with scientists around the world to contribute to space research.
After a year, the amount of fuel remaining will be determined to extend the mission. If the fuel is enough, there is a possibility of modifying the track and performing other missions. On the contrary, if the fuel falls, it will be dragged into the gravity of the moon after three months. Hang Woo-yeon is preparing for five scenarios in preparation for the end of the year.
In the process of developing and launching Danuri, it is also possible to secure more space exploration technology by cooperating in various ways such as NASA and BLT type, location tracking, and shadow cam.
As Korea is already working with the Artemis Mission, space cooperation has been discussed at the recent summit with the US. It is expected that space cooperation between the two countries will be resilient and will help long-term tasks such as exploration of heart.
Lee Sang-yeon, director of Hang Woo-yeon, said, This month’s track line will be an opportunity for us to go out to be a deep cumbers. said.
