Chandrayaan 3 ISROs Greatest Comeback #chandrayaan3 #chandrayaan2 #failure #isro #success #moon AImystry 2023-08-24 | Chandrayaan 3 is an ISRO (Indian Space Research Organization) mission with the primary objective of putting a lander and rover in the highlands near the south pole of the Moon in the August 2023 timeframe and demonstrating end-to-end landing and roving capabilities. It will also make a number of scientific measurements on the surface and from orbit. It comprises a lander/rover and a propulsion module. The lander/rover will be similar to the Vikram rover on Chandrayaan 2, with improvements to help ensure a safe landing. It will be carried to lunar orbit by the propulsion module which will remain in orbit around the Moon and act as a communications relay satellite. Spacecraft and Subsystems The propulsion module is a box-like structure (modified I-3K structure) with one large solar panel mounted on one side and a large cylinder on top (the Intermodular Adapter Cone) that acts as a mounting structure for the lander. The main thruster nozzle is on the bottom. It has a mass of 2145.01 kg, of which 1696.39 kg is propellant for the MMH + MON3 bi-propellant propulsion system. It can generate 738 W power. Communications is via S-Band and attitude sensors include a star sensor, Sun sensor, and Inertial Reference unit and Accelerometer Package (IRAP). The lander is also generally box-shaped (200 x 200 x 116.6 cm), with four landing legs and four landing thrusters. It has a mass of 1749.86 kg, including 26 kg for the rover, and can generate 738 W using side-mounted solar panels. The lander has a number of sensors to ensure a safe touchdown, including an accelerometer, altimeters (Ka-band and laser), Doppler velocimeter, star sensors, inclinometer, touchdown sensor, and a suite of cameras for hazard avoidance and positional knowledge. Reaction wheels are used for attitude control, and propulsion is provided by a MMH and MON3 bipropellant system with four 800 N throttleable engines and eight 58 N throttleable engines. An X-band antenna is used for communications. The lander carries the rover in a compartment with a ramp for deployment onto the surface. The rover is a rectangular chassis, 91.7 x 75.0 x 39.7 cm in size, mounted on a six-wheel rocker-bogie wheel drive assembly. It has navigation cameras and a solar panel that can generate 50 W. It communicates directly with the lander via Rx/Tx antennas. The lander will carry an instrument called Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure surface thermal properties, the Instrument for Lunar Seismic Activity (ILSA) to measure seismicity around the landing site, the Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) to study the gas and plasma environment, and a passive laser retroreflector array provided by NASA for lunar ranging studies. The rover will carry two instruments to study the local surface elemental composition, an Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS). The Propulsion Module / Orbiter will carry one experiment called the Spectropolarimetry of Habitable Planet Earth (SHAPE) to study Earth from lunar orbit.
