prapti_mittal@istrac.gov.insolar-system-astronomyplanetary-science Chandrayaan-2, India’s second mission to the Moon was launched by GSLV-MK-III in July 2019. Mission carries 13 scientific payloads on Orbiter. Orbiter is presently orbiting moon under 100km x 100 km circular orbit. The data collected from the instruments from the orbiter will be received, processed and archived in Indian Space Science Data Center (ISSDC) for dissemination and use by scientific community in India and abroad. The data from Chandrayaan-2 instruments should be archived in such a way that they are easily accessible by Internet through simple interfaces being used elsewhere for similar kind of missions. TMC-2 (Terrain Mapping Camera) is one of the scientific instrument hosted on the Chandrayaan-2 Orbiter. The instrument is passive electro-optical imaging camera operating in visible-panchromatic band (500-800nm), comprising three optical sensors Fore, Nadir and Aft placed with angles of +25 deg, 0 deg and -25 deg to have three stereo views of the same target as spacecraft moves along the track. PDS4 is the de facto international standard for long term archival of planetary science data.TBDhttp://voparis-tap-sandbox.obspm.fr/tableinfo/tmc.epn_coreGeneralUniversityResearchAmateurIsServedByPADC TAP Server on voparis-tap-sandbox.obspm.fr TAP servicehttp://voparis-tap-sandbox.obspm.fr/taptmc Chandrayaan-2, India’s second mission to the Moon was launched by GSLV-MK-III in July 2019.
