All activities are on schedule, all systems normal, says ISRO

Chandrayaan-3: In a mission update on Thursday, the Indian Space Research Organisation (ISRO) reported that all Chandrayaan-3 activities are going ahead according to plan and that all systems are operating normally. A day after Chandrayaan-3’s momentous arrival on August 24, 2023, the majority of the Vikram lander’s payloads were activated. Operations for rover mobility have also started. On August 20, the SHAPE payload on the propulsion module was switched “ON.”

Chandra’s Surface Thermophysical Experiment (ChaSTE), Instrument for Lunar Seismic Activity (ILSA), and Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) are the lander’s payloads that have been activated. The Spectro-polimetry of HAbitable Planet Earth (SHAPE) mission is to investigate spectral and polarimetric measurements of Earth from lunar orbit. This implies that SHAPE will examine the Earth’s spectro-polarimetric fingerprints.

The University of Maryland, Baltimore County (UMBC) Observatory describes spectro-polarimetry as a method for polarising light by first dividing the entering light into its distinct colours and then assessing each color’s polarisation separately.

Scientists can investigate the reflected light from exoplanets to evaluate their habitability by understanding the spectro-polarimetric signals of Earth.

In other words, SHAPE will look for exoplanet signs to determine whether or not a planet is livable.

ChasTE’s job is to measure the thermal characteristics of materials on the lunar surface close to the south pole, including their temperature and thermal conductivity.
The purpose of ILSA is to gauge seismic activity near the landing area. RAMBHA is going to study the plasma environment around the Moon.

Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) are the rover’s payloads.
