The Radar Altimeter will measure the altitude of the moon impact probe above the lunar surface and qualify technologies for future landing missions.
The video-imaging system which comprises of an analog CCD camera along with a video decoder will acquire images of the surface of the moon from the descending probe. The Mass Spectrometer will measure the constituents of tenuous lunar atmosphere during descent.
