The Telescope Array (TA) experiment aims at studying the nature and origin of Ultra-high Energy Cosmic Rays (UHECRs) with energies up to around 10^20 eV. It is located in Utah, USA, and is composed of a ground array of 507 scintillator detectors covering 700 square kilometers and three air fluorescence telescope stations overlooking the array from the periphery. Here I present the recent results of the measurements of UHECR spectrum, anisotropy and composition from TA including the preliminary results at lower energies down to 10^15.6 eV from the TA Low-energy Extension (TALE). And the TA extension plans are also presented.
