Chennai: The Indian space agency on Thursday said ChaSTE, ILSA and RAMBHA -- the payloads of the moon lander -- have been turned on. In a tweet, the Indian Space Research Organisation (ISRO) said: “Lander Module payloads ILSA, RAMBHA and ChaSTE are turned ON today (Thursday).” “Rover mobility operations have commenced. All activities are on schedule. All systems are normal,” ISRO said. According to the space agency, on Sunday the propulsion module payload SHAPE was turned on. On Wednesday evening, India’s moon lander -- part of the Chandrayaan-3 missionn -- safely landed on the lunar surface. The Chandrayaan-3 spacecraft comprises a propulsion module (weighing 2,148 kg), a lander (1,723.89 kg) and a rover (26 kg). With the landing, a major portion of the Rs 600 crore Chandrayaan-3 mission has been realised. The remaining portion is the moon rover rolling down from the lander, moving around and doing the programmed experiments. According to ISRO, the moon rover has Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of the landing site. On its part, the lander too will carry out the tasks assigned to it with its payloads: Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure the thermal conductivity and temperature; Instrument for Lunar Seismic Activity (ILSA) for measuring the seismicity around the landing site; RAMBHA Langmuir Probe (LP) to estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is accommodated for lunar laser ranging studies. The mission life of the lander and the rover is 1 Lunar day or 14 Earth days, ISRO said Earlier ISRO had said in another a tweet: "Chandrayaan-3 ...
