双语新闻：美国宇航局想要更快的月球时钟
The American space agency NASA says it wants to come up with an out-of-this-world way to follow time on its own clock for the moon.
美国国家航空航天局(NASA)表示，他们希望想出一种独特的方法，用自己的时钟跟踪月球的时间。
It would not be connected to the different time zones found on Earth. The moon clock would have an entirely different time for the moon.
它不会与地球上的不同时区相连。月球时钟会显示出完全不同的月球时间。
That is because there is less gravity on the moon. So, time moves a little bit quicker compared to Earth. It moves about 58.7 microseconds faster every day.
这是因为月球上的重力较小。所以，与地球相比，时间走得更快一些。它每天快58.7微秒。
White House officials recently told NASA and other federal agencies to work with international agencies to come up with a time system for the moon.
白宫官员最近告诉美国国家航空航天局和其他联邦机构与国际机构合作，提出一个月球时间系统。
Kevin Coggins is NASA's top communications and navigation official. He said, "An atomic clock on the moon will tick at a different rate than a clock on Earth."
凯文·柯金斯是美国宇航局通信和导航部门的高级官员。他说:“月球上的原子钟和地球上的原子钟会以不同的速度滴答作响。”
The last time NASA sent astronauts to the moon, the astronauts wore watches. But back then, timing was not important as it is now with computers, satellites, and communication systems, he said. And he added that those microseconds make a difference when high tech systems work together.
上一次美国宇航局把宇航员送上月球时，宇航员都戴着手表。但他说，在当时，时间并不像现在的计算机、卫星和通信系统那样重要。他补充说，当高科技系统协同工作时，这些微秒就会产生影响。
Last year, the European Space Agency said scientists needs to come up with a single time for the moon, where a day lasts 29.5 Earth days.
去年，欧洲航天局表示，科学家需要为月球制定一个单一的时间，月球上的一天是29.5个地球日。
The International Space Station is in low Earth orbit. It will continue to use coordinated universal time, or UTC.
国际空间站在近地轨道上运行。它将继续使用协调世界时(UTC)。
NASA must decide where the new space time starts. Even Earth's time speeds up and slows down, requiring a unit of time called leap seconds.
NASA必须决定新的时空从哪里开始。即使是地球的时间也会加速和减慢，需要一个叫做闰秒的时间单位。
The U.S. government wants NASA to come up with a proposal for the time system by the end of this year. It hopes NASA will have a final plan by the end of 2026.
美国政府希望NASA在今年年底之前提出一个时间系统的提案。它希望NASA能在2026年底前制定出最终计划。
NASA is aiming to send astronauts around the moon in September of 2025 and land people on the moon one year later.
美国宇航局的目标是在2025年9月将宇航员送到月球周围，并在一年后将人类送上月球。
