Description:

• KSAT 2 (Kagoshima Satellite 2, also named Hayato 2) is a small 1U CubeSat mission developed by the Kagoshima University. It is a modified reflight of the failed KSAT (Hayato) satellite.
• The KSAT-2 satellite will detach at an altitude of about 400 kilometers, according to the plan. It will orbit the Earth at a speed of 8 kilometers per second and send data to the ground for about 150 days before burning up in the atmosphere. Its mission includes measuring densities and distribution of water vapor in the atmosphere, which could help to increase accuracy in forecasting torrential rain.
• The objectives of the mission are:
  • Study on Forecast of Localized Downpour and Tornado - In-orbit experiments of an original observation method of atmospheric water vapor.
  • Take Earth Live Images from Space - Ku-band high-speed data transmission, one shot / a few seconds.
  • Basic Experiments for LEO Positioning Satellites - Frequency and phase synchronization between a ground-base system and a satellite.
  • Orbit Determination Experiments with Radio Interferometer - Essential item for nano-satellite orbiting at very low earth orbit.
  • Satellite Tracking Experiment at Very Low Earth Orbit - Evaluation of Earth's atmosphere to the satellite.
  • Verification of Pantograph-type Extending Boom in Space - The boom was originally designed and is fit for compact satellites.
  • Messages of Encouragement from Space to Japan - Hand-lettered messages and heart warm pictures, especially from children responsible for the future.
