In the last few hundred meters of the descent, a white-light lamp on the probe will illuminate the surface—which is normally a muddy red because the atmosphere absorbs the blue frequencies of sunlight—allowing the DISR to do a spectral analysis of the sur

在最后数百公尺的下降过程中，探测器上的白光灯将照亮地表（地表通常为暗红色，因为大气吸收太阳光中的蓝色频率），让DISR对地表组成进行光谱分析。
