It comes to us courtesy of a NASA mission launched in 2009 called the lunar reconnaissance orbiter mission.

这是美国宇航局2009年发射的一项任务，叫做月球勘测轨道飞行器任务。

Researchers examined radar measurements by NASA's Lunar Reconnaissance Orbiter, and compared the results with lava tubes on Earth.

研究人员检查了美国航空航天局月球轨道勘测器的雷达测量结果，并将结果与地球上的熔岩洞进行了比较。

Their tools include NASA's $580 million Lunar Reconnaissance Orbiter and the $3 billion SOFIA Telescope which is mounted to a plane.

探测工具包括美国宇航局耗资5.8亿美元打造的月球勘测轨道飞行器，和价值30亿美元的安装在飞行器上的索非亚望远镜。

Scientists have been studying pictures of the moon's surface from NASA's Lunar Reconnaissance Orbiter, part of a half billion dollar mission that was launched in 2009.

科学家们一直在研究美国宇航局月球勘测轨道飞行器空间站拍摄的月球表面照片，这是2009年启动的一项耗资5亿美元的任务的一部分。

Also, NASA's Lunar Reconnaissance Orbiter – which is currently orbiting the moon – will not be in a position to observe the hit as it happens, the spokeswoman said.

这位女发言人称，此外，美国国家航空航天局目前正在绕月飞行的月球勘测器无法在撞击发生时进行观察。

With the Lunar Reconnaissance Orbiter, scientists looked at moon areas that are always shadowed from the sun and theorized that many of these shadows could be filled with ice.

通过月球勘测轨道飞行器，科学家们观察到了月球上经常被太阳遮住的阴影区域，并发现这些区域可能填有冰。

“I’ve been telling people to go out at night on either Sunday or Monday night to see the supermoon, ” said Noah Petro, who works for NASA’s Lunar Reconnaissance Orbiter mission.

“我一直提醒大家，周日或周一晚间出门观赏超级月亮，”诺亚·佩德罗说道，他是NASA月球侦察轨道飞行器任务的工作人员。

The researchers discovered the annexe by analysing data from the Lunar Reconnaissance Orbiter (LRO), which has been circling the Moon since 2009.

研究人员通过分析自 2009 年以来一直在绕月运行的月球勘测轨道器 (LRO) 的数据发现了这个附属建筑。
