Schematic view of the Chandrayaan spacecraft image credit: It is concluded that the strong and localized hydroxyl absorption features are inconsistent with a surficial origin. Missions are ordered by launch date. The instrument is a chandrayzan imaging spectrometer providing two spatial and one spectral dimension use of a HgCdTe detector array.

The craft completed 3, orbits acquiring 70, images of the lunar surface, [70] [71] [72] which many in ISRO believe is quite a record compared to the lunar chanxrayaan of other nations.

Chandrayaan India’s Moon Mission

Retrieved 4 November The Mini-SAR instrument found more than 40 small craters km in diameter with sub-surface water ice located at their base. Instrument mass, power size. Something that had a radar signature of a small spacecraft did cross the beam twice during four hours of observations, and the timings between detections matched the time it would take Chandrayaan-1 to complete one orbit and return to the same position above the moon’s pole.


For many years, researchers believed that the rocks from the moon were bone-dry and any water detected in the Apollo samples had to be contamination from Earth Ref.

The general lack of correlation of this feature in sunlit M 3 data with neutron spectrometer H abundance data suggests that the formation and retention of OH and H 2 O is an ongoing surficial process. It’s read out is similar to a conventional CCD, requiring clock triplets to read out the 1. Since the M 3 instrument observations yield very high data rates, mapping the entire surface of the moon at both high spatial and spectral resolution would exceed the nominal operational lifetime of the mission.

The signals were picked up during a solar flare that caused an X-ray fluorescence phenomenon.
