美国国家航天局（NASA）的南希·格雷丝·罗曼空间望远镜（Nancy Grace Roman Space Telescope）于美国东部时间上午7:57与SpaceX猎鹰重型运载火箭的第二级分离，目前正在独立飞行。

NASA’s Nancy Grace Roman Space Telescope separated from the SpaceX Falcon Heavy’s second stage at 7:57 a.m. EDT and is flying on its own.

罗曼空间望远镜在上升段早些时候的上午7:33通过一颗美国国家航天局（NASA）数据转播卫星（data-relay satellite）建立了通信。任务控制人员将继续监测该天文台，因为它正开始前往距离地球（Earth）约100万英里的第二日地拉格朗日点（Lagrange point），即L2的轨道之旅。

Roman established communications through a NASA Tracking and Data Relay Satellite earlier in ascent at 7:33 a.m. Mission controllers will continue monitoring the observatory as it begins its journey toward an orbit around the second Sun-Earth Lagrange point, or L2, about 1 million miles from Earth.

当罗曼空间望远镜开始科学运行后，近空间网络（Near Space Network）将传输其高速科学数据，而深空探测网（Deep Space Network）将继续提供关键的跟踪数据，包括显示地面团队罗曼空间望远镜在太空中位置的精确距离和角度测量值。欧洲空间局（ESA）和日本航天局（JAXA）将分别通过其New Norcia和Misasa地面站（ground station），为罗曼空间望远镜的数据下行链路提供额外支持。

When Roman begins science operations, the Near Space Network will transmit Roman’s high rate science data, while the Deep Space Network will continue providing critical tracking data, including the precise range and angle measurements that show ground teams where Roman is in space. Additional support for downlinking Roman data will come from ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency), through their New Norcia and Misasa ground stations, respectively.

在接下来的30分钟内，罗曼空间望远镜将部署其太阳能电池阵列遮阳罩，该装置既能提供电力，又兼作隔热罩。分离后，四个外侧面板将摆动到位，形成完整的六面板阵列，为该天文台前往L2的旅程提供动力并保持低温。

In the next 30 minutes, Roman will deploy its Solar Array Sun Shield, which provides power and doubles as a thermal shield. After separation, the four outer panels swing into place to form the full six panel array, keeping the observatory powered and cool for the journey to L2.
