Images sent by Chandrayaan-1 indicate possible impact of Earth's atmosphere on Moon

 

  • Images show that Moon maybe rusting at poles. Also, Chandrayaan-1 data indicates that Moon's poles are home to water.
  • Since surface of Moon is known to have iron-rich rocks, and not water and oxygen, NASA believes that atmosphere might be partly responsible for the same.

About Chandrayaan-1:


  • Launched in 2008. It carried 11 scientific instruments built in India, USA, UK, Germany, Sweden and Bulgaria.
  • Payloads from India: Terrain Mapping Camera, Flyper Spectral Imager, Lunar Laser Ranging Instrument, High Energy X - ray Spectrometer, Moon Impact Probe.
  • Payloads from abroad: Chandrayaan-1 X-ray Spectrometer, Near Infrared Spectrometer, Sub keV Atom Reflecting Analyzer, Miniature Synthetic Aperature Radar, Moon Mineralogy Mapper, Radiation Dose Monitor.
  • It aimed at conducting chemical and mineralogical mapping of the entire lunar surface for distribution of mineral and chemical elements.

Key findings: 


  • Detected water in vapour form in trace amounts, 
  • To confirmed Ocean Magma Hypothesis, 
  • To detected x-ray signals during weak solar flares thus indicating presence of magnesium, aluminium, silicon and calcium on lunar surface.
  • Union Minister of State for Space informed that launch of Chandrayaan-3 may take place in early 2021.
