At the Satish Dhawan Space Centre in Sriharikota on Wednesday (July 05,2023.), the Indian Space Research Organization successfully paired the brand-new heavy lift launch vehicle LVM3 with the encapsulated assembly that contained the Chandrayaan-3 spacecraft. In order to demonstrate end-to-end capability in safe landing and roving on the lunar surface, Chandrayaan-3 is a follow-on mission to Chandrayaan 2. The national space agency with its headquarters in Bengaluru posted a tweet stating that “the encapsulated assembly containing Chandrayaan-3 is mated with LVM3 today at Satish Dhawan Space Centre, Sriharikota.” The Chandrayaan-3 mission, according to ISRO, Space Craft will launch between July 13 and July 19. We are meaning to send off it on July 13”, an ISRO official said. In order to investigate the thermophysical properties of the lunar regolith, lunar seismicity, the lunar surface plasma environment, and elemental composition in the vicinity of the landing site, the Chandrayaan-3 mission carries scientific instruments.
According to officials at ISRO, while the scope of these scientific instruments on the lander and rover would fit the theme of “Science of the Moon,” another experimental instrument will study the Earth’s spectro-polarimetric signatures from lunar orbit, which would fit the theme of “Science from the Moon.” The crucial tests that confirmed the spacecraft’s ability to withstand the harsh vibration and acoustic environment that it would encounter during its launch were successfully completed by the Chandrayaan-3 spacecraft in March of this year. Because the Chandrayaan-3 spacecraft, which will be launched by LVM3 (Launch Vehicle Mark-III) (previously referred to as GSLV Mk III), is a composite of three modules—propulsion, lander, and rover—these tests were particularly challenging.
The drive module, which has Spectro-polarimetry of Livable Planet Earth (SHAPE) payload to study the ghastly and polarimetric estimations of Earth from the lunar circle, will convey the lander and wanderer arrangement till 100 km of the lunar circle. The payloads of the lander are: Chandra’s Surface Thermophysical Trial’ to gauge the warm conductivity and temperature; ‘ Instrument for Lunar Seismic Activity, which is used to measure the area around the landing site’s seismicity; furthermore ‘Langmuir Test’ to gauge the plasma thickness and its varieties.
The US space agency National Aeronautics and Space Administration’s (NASA) passive Laser Retroreflector Array can also be used for lunar laser ranging research. The payloads of the rover are: Alpha Molecule X-beam Spectrometer’ and ‘Laser Prompted Breakdown Spectroscopy’ for determining the essential sythesis nearby the arrival site. The lander will have the capacity to delicate land at a predefined lunar site and convey the wanderer which will do in-situ substance examination of the lunar surface throughout its versatility. The primary function of the propulsion module is to separate and transport the lander module from the injection stage of the launch vehicle into its final 100 km circular polar orbit on the moon. In addition, it was noted that the propulsion module has a single scientific payload as a value addition that will operate following the lander module’s separation.
