chandrayaan-3
Ch
Moonayan is on a journey towards the moon. for the latest situation
Chandrayaan-3 is the follow-up mission of Chandrayaan-2, which displays safe landing and end-to-end capacity of roving on the moon surface. This includes lander and rover configuration. It will be launch by LVM3 from SDSC Shar, Sri harikota. The propulsion module will be take the lander and rover configuration up to 100 km lunar orbit. The propulsion module has a spectro-polarimetry of habitable planet meaning (SHAPE) pedestal to study the Earth’s spectral and polar metric measurements from the lunar orbit.
“say, “”But why do we do such missions? What benefit from them?”””
Lander payload: Lunar surface thermoe thermoeological experiments (Chest) to measure thermal conductivity and temperature; a tower to the lunar seismoeological activity (ILSA) to measure seismic conductivity around the landing site; langmoe probe (LP) to predict the plasma density and its diversity. A passive laser retroreflector Array from NASA has been adjusted for lunar laser ranging studies.
Rover payload: Alpha particle X-ray spectrometer (APXS) and laser induced breakdown spectroscope (LIBS) to get the fundamental structure around the landing site.
Chandrayaan-3 includes an Indigenous Lander Module (LM), Propulsion Module (PM) and a Rover, the aim of developing and demonstrating new technologies needed for intergraduate missions. Lander will have the ability to land soft on the specified lunar site and deploy the rover which will do the in-seatoo chemical analysis of the lunar surface during its mobility. Lander and Rover have scientific payments to use on the moon surface. The main task of PM is to take the LM from the launch vehicle injection to the final lunar 100 km spherical polar orbit and separate the LM from PM. In addition, the propulsion module also has a scientific payload as a value amplification which will be operated after the lander module is separated. The launch lauded for Chandrayaan-3 is the LVM3 M4 which will install the integrated module in ~170×36500 km size of aliptic parking orbit (EPO).
The objectives of Chandrayaan-3 are:
Display safe and soft landing on the moon surface
Performing the rover to the moon and tour
use aspirational scientific
There are several advanced technologies in the lander to achieve mission objectives such as,
Ultimeter: Laser and RF based altimeter
Velocimeter: Laser Dopler Velocimeter and Lander Horizontal Velocity Camera
Inertial Measurement: Laser Gayro based inertial reference and accelerometer package
Propulsion system: 800N throttleable liquid engine, 58N etitude thrusters and throttleable engine control electronics
Shipping, Guidance and Control (NGC): Powered Disent Trajectory Design and Associate Software Elements
Detect and Rescue: Lander Detect danger and rescue camera and processing algorithms
landing leg mechanism
To display the above advanced technologies in the earth’s condition, many lander special tests have been planned and successfully completed.
Integrated Cold Test – Performance of integrated sensor and shipping performance testing using helicopters as test platform
Integrated Hot Test – Performance of closed loop performance test with sensors, actors and NGC using tower crane as test platform
The Lander Leg Mechanism Performance test emulates various touch down conditions on a Luner Simulant Test Bed
