NASA’s Roman Space Telescope: Falcon Heavy Side Boosters Begin Return

搭载NASA南希·格雷丝·罗曼空间望远镜（Nancy Grace Roman Space Telescope）的SpaceX猎鹰重型运载火箭上的两个侧助推器已与中心芯级分离。

The two side boosters on the SpaceX Falcon Heavy carrying NASA’s Nancy Grace Roman Space Telescope have separated from the center core.

在发射后约2分24秒关闭发动机后，助推器在几秒钟后分离并执行了翻转机动，以调整姿态进行返回。它们的返回点火随后开始，预计持续时间略超过一分钟。

After shutting down their engines at about 2 minutes, 24 seconds after launch, the boosters separated seconds later and executed a flip maneuver to orient themselves for their return. Their boost back burns began shortly afterward and are expected to last just over one minute.

SpaceX猎鹰重型运载火箭的中心芯级继续为第二级和罗曼空间望远镜的旅程提供动力。主发动机关机计划在T+3分51秒进行，随后是级间分离和第二级Merlin Vacuum发动机的点火。

The SpaceX Falcon Heavy’s center core continues powering the second stage and Roman on its journey. Main engine cutoff is planned for T+3 minutes, 51 seconds, followed by stage separation and ignition of the second-stage Merlin Vacuum engine.

侧助推器计划在T+7分40秒左右降落在卡纳维拉尔角（Cape Canaveral）太空军基地的发射场附近。请通过NASA+及多个平台观看直播。

The side boosters are scheduled to land near the launch site at about T+7 minutes, 40 seconds, at Cape Canaveral Space Force Station. Watch live on NASA+ and a variety of platforms.
