英文摘要	Search for Terrestrial Exo-Planest (hereafter STEP) mission is a latest advanced research project in Chinese Strategic Pioneer Program (SPP) on Space Science. STEP aims at the nearby earth-alike planets detection, comprehensive research on the planetary system and some astrometry research with 1 micro-arcsecond precision in the space, which will get the fruitful achievements in the exo-planetary and astrometry research fields. STEP will take the Space Astrometry technique in the optical band. The FOV is 0.44 degree, based on 1.2m primary and focus length is 50 m. The special metrology technique will be taken to reach 0.5 similar to 1 uas astrometry precision, which will be ideal for terrestrial exo-planets detection.
