NEXTSat 1 () is a multi-purpose microsatellite designed and developed at SaTReC (Satellite Technology Research Center) of KAIST (Korea Advanced Institute of Science and Technology).

The purpose of the NEXTSat 1 mission are:

  • To develop the next-generation small satellite series and new technologies by creating a standardized platform for small satellites based on miniaturization, modularization and standardization.
  • To conduct in-orbit verification of core space technologies that will enhance domestic space capabilities and enhance technological competitiveness for import substitution.
  • To develop space technologies and enhance independent space development capabilities through geo-environmental monitoring and astronomical observation
  • Hands-on and customized development of researchers and scientists through field experience in space technologies and science

The NEXTSat 1 payloads are:

  • Instrument for the Study of Space Storms (ISSS), developed at KAIST to detect plasma densities and particle fluxes of 10 MeV energy range near the Earth
  • NIR Imaging Spectrometer for Star formation history (NISS), developed at the Korean Astronomy and Space Science Institute (KASI), is a passively cooled near-Infra-red spectrometer with 15 cm aperture optics with a spectral coverage of 0.93.8 m
