NASA的南希·格雷斯·罗曼太空望远镜于8月30日美东时间上午7:26从佛罗里达州肯尼迪航天中心39A发射复合体搭乘SpaceX猎鹰重型火箭升空,开启了这项酝酿多年的任务。这台以NASA首位首席天文学家命名的天文台,设计用于以远超哈勃或詹姆斯·韦布太空望远镜的规模巡视天空,其视场约为哈勃的100倍,同时保持相当的成像清晰度。
猎鹰重型火箭的27台梅林发动机产生超过500万磅推力将火箭推离大气层,罗曼望远镜于发射后31分钟、美东时间上午7:57与火箭上面级顺利分离。望远镜目前正飞向被称为L2的引力稳定点,该点位于地球背向太阳一侧约一百万英里处,罗曼将在那里与韦布望远镜一同运行,其仪器可免受太阳热量和光线影响。
未来几周内,任务工程师将展开罗曼望远镜的太阳能板、校准仪器,并执行中途修正机动以精确调整轨道,随后正式开始科学观测。投入运行后,罗曼预计将绘制数十亿个星系的图谱,利用被称为微引力透镜的技术搜寻数千颗新系外行星,并为研究暗能量和宇宙结构的天文学家每天生成海量数据。
