This is South Korea's newest satellite, the Chollian-2B - the world's first geostationary satellite that can monitor the atmospheric environment.
After seven years of development, the satellite was finally unveiled at the Korea Aerospace Research Institute on Thursday.
The major mission of the Chollian-2B is to monitor the atmosphere and the ocean environment.
It will observe the path of fine dust from the Korean Peninsula and its neighboring countries while collecting data on more than 20 kinds of air pollutants.
"By providing satellite data in real timewe can monitor air pollutants entering our country, especially fine dust. Therefore, we expect the accuracy of the forecast for fine dust to be increased quite a bit."
The Chollian-2B can also monitor the oceanic environment with a resolution four times greater than the Chollian-1, which was launched in 2010.
The satellite will help minimize damage from red or green tides by tracking ocean movements in real time.
What's even more remarkable about the Chollian-2B is that the entire process - designing, assembling and testing - was done using Korean technology.
"The most important parts in a satellite are computers and softwareand all these components have been localized."
The Chollian-2B will be moved to the Guiana Space Center in early January and the launch is expected to take place around mid-February.
