At a two-day lunar science workshop livestreamed on Facebook and YouTube, marking the completion of two years of the second Moon mission launched on July 22, 2019, ISRO Chairman K Sivan said Chandrayaan-2 data is “national property” and implored the scientific and academia community to utilise the same for furthering science.

Sivan, who is also the secretary of Department of Space, released the science and data product documents from the mission output so far.

One of the sessions discussed payload results of Chandrayaan-2 Large Area Soft X-Ray Spectrometer (CLASS) measures the Moon’s X-ray Fluorescence (XRF) spectra to examine the presence of major elements such as magnesium, aluminium, silicon, calcium, titanium, iron, and sodium. Discussing the science results from it, principal investigator Shyama Narendranath, of CLASS payload stated that it has seen “definite detection of (minor elements) chromium and manganese for the first time (from the lunar surface through remote sensing), which was a surprise as these (elements) are less than one weight percentage on the moon”.

The two elements were detected at few places during intense solar flare events. The presence of the elements on the lunar surface was known so far through soil samples collected during earlier moon missions.

According to a statement from ISRO, the eight payloads onboard Chandrayaan-2 are conducting scientific observations of the Moon by remote sensing and in-situ techniques.
