The CALorimetric Eletron Telescope (CALET).
CALET is a high-energy astroparticle experiment planned for a long exposure mission aboard the ISS Station by JAXA, ASI and NASA. The main goal is precision measurements of electrons up to 10 TeV where the shape of the spectrum might unveil the presence of nearby sources of acceleration. Excellent energy resolution and background rejection power allow searching for spectral signatures of dark matter with both electrons and gamma rays. In addition CALET will measure the high-energy spectra and abundance of cosmic nuclei from H to Fe, will detect trans-iron elements up to $Z=40$ and will study the energy dependence of the $B/C$ ratio, below and above 1 TeV/N. Gamma-ray transients will be studied with a dedicated Gamma-ray Burst Monitor (GBM). The main CALET performances and its measurement perspectives will be illustrated.
