为未来的阿耳忒弥斯月球任务启动RS-25引擎测试

NASA conducted its fourth RS-25 single-engine hot fire test of the year on May 20, 2021, a continuation of its seven-part test series to support development and production of engines for the agency’s Space Launch System (SLS) rocket on future missions to the Moon. The engine was fired for more than 8 minutes (500 seconds) on the A-1 Test Stand at Stennis Space Center, the same amount of time RS-25 engines need to fire for launch of the SLS rocket.

As part of the Artemis program, NASA will land the first woman and the first person of color on the Moon and establish sustainable exploration in preparation for missions to Mars. SLS and NASA’s Orion spacecraft, along with the commercial human landing system and the Gateway outpost in orbit around the Moon, are NASA’s backbone for deep space exploration.

美国国家航空航天局于2021年5月20日进行了今年的第四次RS-25单引擎热火测试，这是其七部分测试系列的延续，以支持NASA太空发射系统（SLS）火箭在未来的月球任务中的引擎开发和生产。发动机在斯坦尼斯航天中心的A-1试验台上点火超过8分钟（500秒），与发射SLS火箭所需的RS-25发动机点火时间相同。

作为阿耳忒弥斯计划的一部分，NASA将让第一位女性和第一位有色人种登陆月球，并建立可持续探索，为火星任务做准备。SLS和NASA的猎户座飞船，以及商业载人着陆系统和绕月轨道的门户前哨站，是NASA进行深空探索的支柱。
