and a great many effective scientific data was obtained. On April 15, 2014, the
lunar lander passed the first lunar eclipse. During the lunar eclipse, the temperature
of instruments and two-phase fluid loops met the design requirements. The typical
temperature changes of the working equipment and fluid loop are shown in Figs. 5.25
and 5.26, where the lowest temperature can be seen before exit of the umbra.
