Chandrayaan 2 makes exciting new discovery below moon surface. CHACE-2 Onboard Chandrayaan-2 Orbiter makes the First Observations of the Global Distribution of Argon-40 in the Exosphere of Moon Chandrayaan-2 observed Argon-40 in the outer atmosphere of the Moon The Chandra’s Atmospheric Composition Explorer-2 (CHACE-2), a quadrupole mass spectrometer onboard Chandrayaan-2 mission has made the first-of-its-kind observations of the global distribution of Argon-40 in the tenuous lunar exosphere.  These observations provide insight on the dynamics of the lunar exospheric species, as well as on the radiogenic activities in the first few tens of meters below the lunar surface. ‘Exosphere’ is the outermost region of the upper atmosphere of a celestial body where the constituent atoms and molecules rarely collide with each other and can escape into space. Earth’s Moon features a surface-boundary-exosphere. For Moon, different constituents in the exosphere are fed from the surface by a v...

Last month, the distance between Chandrayaan-2 Orbiter and LRO was very low. Indian Space Research Organization (ISRO) said that what changes were made from which this incident Chandrayaan-2_NASA_Lro_were_absolutely_close New Delhi Last month, the strange situation came in front of ISRO when Chandrayaan-2 and NASA's Lunar Riconics Orbitter had come close to collide. Indian Space Research Organization (ISRO) has revealed that Chandrayaan 2 orbit was changed to its polar class to protect NASA's Lunar Riconics Orbiter (LRO) in October. To avoid colliding with NASA's LRO near the North Pole, it was transferred from its polar class last month. Chandrayaan-2_NASA_Lro_were_absolutely_close Last month, the distance between Chandrayaan-2 Orbiter and LRO was very low. The radial separation between the spacecraft will be less than 100 meters and the closest distance will be only 3 km at the above time and the nearest distance will be only 3 km at the above time.
