STEP aims at the nearby earth-alike planets detection  comprehensive research on the planetary system and some astrometry research with 0.5 uas 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 50m. The special metrology technique will be taken to reach 0.5 uas astrometry precision  which will be idea for terrestrial exo-planets detection. The mission will take the L2 orbit.   The Research of Deep Space Life Exploration Based on Fluorescence 会议论文 International Symposium on Photoelectronic Detection and Imaging 2011 - Space Exploration Technologies and Applications, Beijing, PEOPLES R CHINA, MAY 24-26, 2011 作者:  Shi Hua-yong;  Jiang Yuan-da;  Sun Zhi-bin;  Liu Xue-feng;  Gao Shang-qi 收藏  |  浏览/下载：13/0  |  提交时间：2014/12/15 Deep space life exploration  Fluorescence detection  fiber coupled LED  CCD
