NASA uses Chandrayan’s data to detect water on Moon

Scientists from the US space agency NASA have detected magmatic water under the Moon’s surface. They used the data collected by the Moon Mineralogy Mapper (M3) instrument aboard the Indian Space Research Organisation’s (ISRO) Chandrayaan-1 spacecraft, to remotely detect magmatic water, or water that originates from deep within the Moon’s interior, on the lunar surface.

What is Moon Mineralogy Mapper (M3)?

The Moon Mineralogy Mapper (M3) was one of two instruments that NASA contributed to India’s first mission to the Moon, Chandrayaan-1, launched on October 22, 2008. The instrument was managed by NASA’s Jet Propulsion Laboratory.

M3 imaged the lunar impact crater Bullialdus, which lies near the lunar equator. In 2009, M3 provided the first mineralogical map of the lunar surface and discovered water molecules in the polar regions of the Moon.

Stage set to launch India’s first defence satellite

India’s first defence satellite GSAT-7 dedicated to Navy for maritime security is now set for the launch. The home-built satellite will be crucial as it will overcome Navy’s previous limitations from line of sight and ionospheric effects and will have coverage over India landmass as well as surrounding seas. It will be significant from security and surveillance points of view.

Key features of GSAT-7:
  • Indigenous
  • Cost: Rs 185 crore
  • Launch Cost: Rs 470 crore
  • Geo-stationary communication satellite
  • Carries payloads operating in UHF, S, C and Ku bands.
  • Lift-off mass of 2625 kg, heavy satellite
  • Strengthen Navy’s maritime security ability
  • Overcomes previous limitations from line of sight and ionospheric effects

The satellite will be launched into Geosynchronous Transfer Orbit (GTO) by Ariane-5 VA 215 by European space consortium Arianespacefrom Kourou spaceport in French Guiana.
