[Nuri Rocket 4th Launch] NGMSAT-3: From Space Environment Research to Space Bio Demonstration

Two Scientific Experiments Combined on a Single Satellite for the First Time

The Next-Generation Medium-Sized Satellite No. 3 (NGMSAT-3), which will be launched into space alongside the fourth launch of the Nuri rocket, is regarded as a multipurpose research platform. It will conduct precise observations of the space environment, including auroras, the ionosphere, and Earth's magnetic field, while simultaneously carrying out space medicine experiments.

As the impact of solar activity has increased-evidenced by the recent observation of mid-latitude auroras and communication disruptions overseas due to solar flares-the importance of monitoring the space environment has grown further. This satellite will play a key role in securing data to respond to these changes.

The First Case of Combining Space Environment Observation and Space Medicine Experiments

The aurora and airglow observation instrument (ROKITS) mounted on NGMSAT-3 fills in observational gaps around midnight and captures high-resolution images of auroral expansion and energy influx. The observation equipment (IAMMAP) developed by KAIST, which simultaneously measures ionospheric plasma and magnetic field changes, provides precise data to analyze the causes of space environment disturbances such as communication failures and GPS errors. These instruments will be used to track the energy flow from the solar wind to the magnetosphere and ionosphere, serving as a foundation for enhancing satellite operational stability and space weather forecasting capabilities.

NGMSAT-3 is also equipped with the "BioCabinet," which performs cell culture and 3D bioprinting in a microgravity environment. Developed by a research team at Hallym University, this device is the first domestic system capable of conducting independent space life science experiments without passing through the International Space Station. For this mission, it will observe the differentiation and tissue formation processes of cardiac stem cells and tonsil-derived stem cells. The goal is to identify the characteristics of cellular changes in the space environment and establish a foundation for regenerative medicine and space medicine research.

Kang Kyungin, Director of the Space Science and Exploration Division at the Space Agency, stated, "The BioCabinet is significant as it marks the first attempt at a space medicine experiment using a Korean satellite," adding, "We will continue to expand research utilizing microgravity, in addition to observing the space environment."

The fourth launch of the Nuri rocket is expected to serve as a starting point for Korea to expand its scope from space environment research to space medicine experiments, as it will be the first case where scientific observation and space medicine demonstration are conducted simultaneously on a single satellite.
