Chennai- India’s moon lander efficiently set its 4 legs softly and safely on the lunar soil on Wednesday night as deliberate, and have become the fourth nation on this planet to realize the feat.

The lander landed close to the South Pole of the moon after travelling about 3.84 lakh km for over 40 days.

With the touchdown, a serious portion of the Rs 600 crore Chandrayaan-3 mission has been realised. The remaining portion is the moon rover rolling down from the lander, shifting round and doing the programmed experiments.

The Chandrayaan-3 spacecraft contains a propulsion module (weighing 2, 148 kg), a lander (1, 723.89 kg) and a rover (26 kg).

According to the Indian Space Research Organisation (ISRO), the moon rover has Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the fundamental composition within the neighborhood of the touchdown website.

On its half, the lander too will perform the duties 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 across the touchdown website; Langmuir Probe (LP) to estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is accommodated for lunar laser ranging research.

The mission lifetime of the lander and the rover is 1 Lunar day or 14 Earth days, ISRO mentioned

The propulsion module has Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to check the spectral and Polari metric measurements of Earth from the lunar orbit.

The lifetime of the payload carried by the propulsion module publish ejection of the lander is between three and 6 months.

The 19 minutes of suspense and pleasure started at 5.45 p.m., as deliberate earlier, and ended at 6.05 p.m. with the lander touching down on the lunar soil.

It could also be recalled that the Vikram lander that was a part of the Chandrayaan-2 mission a few years again had crashed on the moon whereas it was on the final section of touchdown.

The comfortable touchdown is a tough situation because it includes a collection of advanced manoeuvres consisting of tough and nice braking.

Imaging of the touchdown website area previous to touchdown might be completed for locating secure and hazard-free zones.

The powered descent of the lander in a horizontal place started from an altitude of about 30 km at about 5.45 p.m. The computerized touchdown sequence bought activated.

During the tough breaking section the lander’s pace might be introduced down from 1, 680 metres per second to 358 metres per second. The altitude might be introduced down 7.4 km above the moon.

The subsequent section was the altitude maintain section the place the altitude was introduced down to six.8 km.

The officers seated on the Mission Operations Complex at ISRO Telemetry, Tracking and Command Network (ISTRAC), Bengaluru, had their eyes glued to their screens.

The lander’s place modified to vertical and the craft hovered 150 metres over the moon, taking footage and surveying the touchdown zone to determine on a secure touchdown spot.

Then the secure touchdown occurred with two engines on out of the 4.

The main communication channel would be the Mission Operations Complex at ISTRAC, Bengaluru, to Chandrayaan-3 Propulsion Module which in flip would speak to the lander and the rover.

Recently, the moon lander established communication hyperlinks with the Chandrayaan-2 mission’s Orbiter that’s circling the moon since 2019 and thereby having a backup speaking channel.

Meanwhile, the propulsion module of Chandrayaan-3 is continuous to go across the moon for some extra interval with its payload Spectro-polarimetry of Habitable Planetary Earth (SHAPE) doing its job.

The Chandrayaan-3 was put into orbit on July 14 in a copybook fashion by India’s heavy carry rocket LVM3.

The spacecraft accomplished orbiting across the Earth and headed in the direction of the moon on August 1.
