Landsat 9号卫星就位进行封装

Inside the Integrated Processing Facility at Vandenberg Space Force Base in California, the Landsat 9 spacecraft is moved into position for encapsulation on Aug. 16, 2021. The two halves of the United Launch Alliance (ULA) payload fairing will surround and encase Landsat 9 to protect it during launch atop the ULA Atlas V rocket.

Landsat 9 will launch on the Atlas V rocket from Space Launch Complex 3 at Vandenberg in September of this year. The launch is being managed by NASA’s Launch Services Program based at Kennedy Space Center, America’s multi-user spaceport.

The Landsat 9 satellite, managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, will continue the nearly 50-year legacy of previous Landsat missions. It will monitor key natural and economic resources from orbit. The satellite will carry two instruments: the Operational Land Imager 2, which collects images of Earth’s landscapes in visible, near infrared and shortwave infrared light, and the Thermal Infrared Sensor 2, which measures the temperature of land surfaces. Like its predecessors, Landsat 9 is a joint mission between NASA and the U.S. Geological Survey.

2021年8月16日,在加利福尼亚州范登堡空军基地的综合处理设施内,Landsat 9号卫星移动到位以进行封装。联合发射联盟(ULA)有效载荷整流罩的两半将包围和封装Landsat 9号卫星,以在ULA宇宙神Ⅴ号运载火箭上发射时保护它。

Landsat 9号卫星将于今年9月在范登堡的3号航天发射场用宇宙神Ⅴ号运载火箭发射。这次发射由NASA的发射服务项目管理,该项目位于美国的多用户航天中心肯尼迪航天中心。

由位于马里兰州格林贝尔特的美国国家航空航天局戈达德太空飞行中心管理的Landsat 9号卫星,将延续过去近50年的Landsat卫星任务。它将从轨道上监测关键的自然和经济资源。这颗卫星将携带两个仪器:操作陆地成像仪2号,收集可见光、近红外和短波红外光下的地球景观图像;以及热红外传感器2,测量陆地表面的温度。与其前身一样,Landsat 9号卫星是NASA和美国地质调查局的一项联合任务。
