SMILES
Global environmental observation from the Japanese Experiment Module, KIBO
The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) is an atmospheric observation sensor of unprecedented high sensitivity with superconducting technology. SMILES is the instrument to observe the global environment in the Japanese Experiment Module "KIBO" aboard the International Space Station (ISS). SMILES was jointly developed by the National Institute of Information and Communication Technology (NICT) and the Japan Aerospace Exploration Agency (JAXA).

SMILES observes the atmosphere that protects the earth
Many cosmic rays and particles harmful to living things travel through space and strike the planet that we live on. The earth’s atmosphere is one of the most important barriers which absorb them and protect life on the earth. In addition, atmospheric environmental concerns such as ozone depletion, global warming and air pollution caused by PM2.5 are becoming serious issues in recent years. There remain many mysteries of the atmosphere that have not been unraveled yet. Highly sensitive data obtained through SMILES observation opens a new issue of atmosphere that protects the earth, the home of humankind. It contributes to global environmental diagnosis.
