The observation phase of SMILES terminated. The conclusion of the failure investigation about submillimeter-wave local oscillator was reported. (more)
The cause of the discontinuance of the SMILES observation at 08:59:55 of 21th April 2010 (UT) was identified as a failure of submillimeter-wave local oscillator. (more)

SMILES began the test observations from October 10. It was confirmed that all instruments work normally, and expected low noise high quality atmospheric emission spectra ware obtained The initial result of the atmospheric abundance of observation molecule was also obtained.
