Detailed explanation-1: -A Large Area Soft X-ray Spectrometer (CLASS), a payload on-board Chandrayaan-2 Orbiter, has detected solar proton events which significantly increase the radiation exposure to humans in space, the Indian Space Research Organisation has said.

Detailed explanation-2: -SPE event was seen by NASA’s Geostationary Operational Environmental Satellite (GOES) satellite orbiting around Earth. However, the CME event was not detected by GOES. Chandrayaan-2 Large Area Soft X-ray Spectrometer (CLASS) on-board Chandrayaan-2 Orbiter detected SPE due to an M5.

Detailed explanation-3: -Chandrayaan-2 is an Indian mission to send an orbiter, lander, and rover to the Moon. The lander crashed in the Moon’s southern hemisphere in 2019. The orbiter is mapping the Moon’s topography, investigating the surface’s mineralogy and elements, studying the lunar exosphere, and looking for signatures of water ice.

Detailed explanation-4: -Chandrayaan-1, India’s first mission to Moon, was launched successfully on October 22, 2008 from SDSC SHAR, Sriharikota. The spacecraft was orbiting around the Moon at a height of 100 km from the lunar surface for chemical, mineralogical and photo-geologic mapping of the Moon.

Detailed explanation-5: -ISRO scientists used Mangalyaan to probe the solar corona, while Chandrayaan instruments picked up solar activity. Chandrayaan recorded events that instruments in Earth orbit did not register because of the Earth’s magnetic field. ISRO scientists used the Mars Solar Conjunction to investigate the corona of the Sun.
