美国国家航空航天局（NASA）的Nancy Grace Roman太空望远镜从佛罗里达州肯尼迪航天中心成功发射升空2。该望远镜将进行为期100天的旅程，前往距地球约100万英里的位置2，并在发射后约30分钟从SpaceX火箭分离2。
Nancy Grace Roman太空望远镜以1960年代NASA首位首席天文学家Nancy Grace Roman的名字命名2。这台望远镜的视场比哈勃和詹姆斯·韦伯望远镜大100倍2，设计寿命为5年，目标可延至10年2。NASA管理员Nicky Fox表示，该望远镜"可能发现数万个，甚至10万颗新的系外行星"2。
该望远镜的关键科学目标包括探测占宇宙约95%的暗能量和暗物质2，发现和表征系外行星，绘制数十亿星系的分布图，以及研究黑洞等天体2。
NASA has launched the Nancy Grace Roman Space Telescope from Kennedy Space Center in Florida on Sunday morning, beginning a 100-day journey to reach its operational position approximately one million miles from Earth 2. The telescope, named after NASA's first chief astronomer from the 1960s, will separate from its SpaceX rocket about 30 minutes after launch 2.
The Roman Space Telescope represents a significant advancement in astronomical capability, featuring a field of view 100 times larger than both the Hubble and James Webb Space Telescopes 2. NASA Administrator Nicky Fox stated the observatory may discover "tens of thousands, potentially up to 100,000 new exoplanets" 2. With a primary mission lifespan of five years and a target operational life of ten years, the telescope is designed to detect dark energy and dark matter—which comprise approximately 95 percent of the universe—while mapping billions of galaxies, characterizing exoplanets, and studying black holes 2.
