但也存在令人信服的理由支持再度登月，其中包括试图确定月球的年龄。
But there are compelling reasons in favor of another Moon landing too, not the least of which is trying to pinpoint the moon's age.
月球的年龄和阶段都显示你目前的经度和纬度的基础上显示。
Moon age and phase are shown on the display based on your current latitude and longitude.
主屏幕显示当前的月相，月球的年龄，距离，纬度，经度和十二星座。

和在月球的一样，大型撞击陨石坑的范围之广可以显示出火星表面的年龄。
As on the Moon, the extent of large impact cratering serves as an age indicator for the Martian surface.
与月球上相同，那些巨大陨石坑的范围（例如，那些巨大到自形成后尚未被尘埃填满的陨石坑）标志着火星表面的年龄。
As on the Moon, the extent of large impact cratering (i.e. craters too big to have been filled in by erosion since they were formed) serves as an age indicator for the Martian surface.
研究人员说这非常重要，因为月表陨石坑的数量可以帮助他们确定月球表面的年龄和深度数据。
The researchers say that's important because it can help them determine the age and depth of the lunar surface.
