been identified. The Oriental Basin region of the Moon was mapped, and it indicates abundance of iron-bearing minerals such as pyroxene. In 2018 it was announced that M3 infrared data had been re-analyzed to confirm the existence of water across wide expanses of the Moon's polar regions. Mapping of Apollo landing sites ISRO announced in January 2009 the completion of the mapping of the Apollo Moon missions landing sites by the orbiter, using multiple payloads. Six of the sites have been mapped including landing sites of Apollo 15 and Apollo 17. Image acquisition The craft completed 3,000 orbits acquiring 70,000 images of the lunar surface, which is quite a record compared to the lunar flights of other nations. ISRO officials estimated that if more than 40,000 images have been transmitted by Chandrayaan's cameras in 75 days, it worked out to nearly 535 images being sent daily. They were first transmitted to Indian Deep Space Network at Byalalu near Bangalore, from where they were flashed to ISRO's Telemetry Tracking And Command Network (ISTRAC) at Bangalore. Some of these images have a resolution of down to , providing a sharp and clear picture of the Moon's surface, while many images sent by some of the other missions had only a 100-metre resolution. For comparison, the Lunar Reconnaissance Orbiter Camera has a 0.5 meter resolution. On 26 November, the indigenous Terrain Mapping Camera, which was first activated on 29 October 2008, acquired images of peaks and craters. This came as a surprise to ISRO officials because the Moon consists mostly of craters. Detection of X-Ray signals The X-ray signatures of aluminium, magnesium and silicon were picked up by the C1XS X-ray camera. The signals were picked up during a solar flare that caused an X-ray fluorescence phenomenon. The flare that caused the fluorescence was within the lowest C1XS sensitivity range. Full Earth image On 25 March 2009 Chandrayaan beamed back its first images of the Earth in its entirety. These images were taken with the TMC. Previous imaging was done on only one part of the Earth. The new images show Asia, parts of Africa and Australia with India being in the center. Orbit raised to 200 km After the completion of all the major mission objectives, the orbit of Chandrayaan-1 spacecraft, which had been at a height of from the lunar surface since November 2008, was raised to . The orbit raising
