First 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 first instrument to observe the global environment in the Japanese Experiment Module "KIBO" onboard the International Space Station (ISS).

The atmosphere protects Earth

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. SMILES was jointly developed by the National Institute of Information and Communication Technology (NICT) and the Japan Aerospace Exploration Agency (JAXA).
