The American space agency NASA recently launched its powerful Space Launch System (SLS) rocket and Orion spacecraft on a test mission to fly around the moon.
美国宇航局最近发射了强大的太空发射系统 (SLS) 火箭和猎户座飞船，执行绕月飞行测试任务。
 
The launch marked the first flight for SLS, which NASA describes as the most powerful rocket ever built. The project has faced years of delays and is running billions of dollars over budget.
此次发射标志着 SLS 的首次飞行，NASA 将其描述为有史以来最强大的火箭。该项目已面临多年延误，并超出预算数十亿美元。
 
Now that the rocket has launched and successfully deployed its spacecraft, we are taking a closer look at the mission NASA says is the first step in returning astronauts to the moon.
现在火箭已经发射并成功部署了航天器，我们正在仔细研究 NASA 所说的第一个任务使宇航员重返月球的一步。
 
Artemis
 
The SLS mission is part of NASA's Artemis program, which aims to land Americans on the moon by the mid-2020s. It would be the first moon landing by astronauts since NASA's Apollo 17 mission in 1972. The next crew to land on the moon is expected to include the first woman and the first person of color.
SLS 任务是 NASA Artemis 计划的一部分，该计划的目标是在 2020 年代中期让美国人登上月球。这将是自 1972 年美国宇航局阿波罗 17 号任务以来宇航员首次登月。预计下一位登陆月球的宇航员将包括第一位女性和第一位有色人种。
