Busan has successfully launched 'BusanSat,' the first ocean-observation micro-satellite developed by a Korean local government, marking the start of a data-driven administrative era based on ocean-space convergence. The launch is seen as more than a space project, signaling a shift in the industrial landscape of Korea's maritime capital toward a data-centered model.
The city said Tuesday that BusanSat was launched aboard SpaceX's Falcon 9 rocket from Vandenberg Space Force Base in California on Monday local time. The satellite separated normally in orbit at an altitude of 615 kilometers about two hours after liftoff and established its first contact with a ground station in Punta Arenas, Chile, the same day, entering a stable initial operation phase.
BusanSat is a 12-kilogram, 12U-class (20×20×30 centimeters) micro-satellite jointly developed by the city of Busan, the Korea Astronomy and Space Science Institute, and Nara Space Technology. For the next year, it will collect data on marine fine dust and atmospheric conditions over Busan Port, the west coast of the Korean Peninsula, and the Pacific Ocean. The satellite is equipped with a polarization camera (Polcube) capable of analyzing fine dust particle characteristics beyond the limitations of conventional optical cameras, significantly enhancing observation precision.
The technology is an Earth-observation adaptation of equipment used on Danuri, Korea's first lunar orbiter, and can simultaneously analyze pollutants on the ocean surface and in the atmosphere. With the ability to penetrate cloud layers, the satellite is expected to substantially improve the accuracy of climate change research and air quality forecasting.
Busan plans to build an 'ocean-plus-space' fusion data ecosystem on the back of the launch. The city intends to use the collected data directly to address urban challenges such as port operations, air quality policy, and marine fine dust response, while partnering with research institutes and companies to create new industries.
The city also plans to advance data analysis and application technologies through cooperation with global research organizations, including NASA, and to accelerate the formation of a 'data-based maritime industry cluster' by opening the data to local universities and companies.
"The BusanSat launch is the starting point for Busan, Korea's maritime capital, to directly secure data through space technology," Acting Busan Mayor Kim Kyung-deok said. "We will connect the observation data to climate change response and the development of new marine industries, taking the city's competitiveness to the next level."
