为Artemis测试奠定基础

All eyes are on south Mississippi with this month’s delivery and installation of NASA’s Space Launch System (SLS) rocket’s first core stage to Stennis Space Center for a milestone Green Run test series prior to its Artemis I flight.

The Green Run testing will be the first top-to-bottom integrated testing of the stage’s systems prior to its maiden flight. The testing will be conducted on the B-2 Test Stand at Stennis, located near Bay St. Louis, Mississippi, and the nation’s largest rocket propulsion test site. Green Run testing will take place over several months and culminates with an eight-minute, full-duration hot fire of the stage’s four RS-25 engines to generate 2 million pounds of thrust, as during an actual launch.

本月，NASA 太空发射系统（SLS）的第一个核心阶段交付并安装到斯坦尼斯航天中心，在“阿尔忒弥斯1号”(Artemis I)飞行前进行里程碑式的初次运行测试，所有的目光都集中在密西西比南部。

初次运行测试将是该阶段系统在首飞前的第一次自上而下的综合测试。测试将在位于密西西比州圣路易湾附近的斯坦尼斯B-2试验台进行，同时也是美国最大的火箭推进测试场地。初次运行测试测试将历时数月，最终将在该阶段的四台RS-25发动机上进行为时八分钟的全持续热火试验，最终产生200万磅的推力。
