Chandrayaan-3 Landing Highlights: What Chandrayaan-3's Vikram Lander And Pragyan Rover Will Do On The Moon
Chandrayaan 3 Moon Landing Live: Chandrayaan-3 successfully landed on the Moon on August 23, 2023, at 6:04 pm IST, making India the first country to softly land a spacecraft on the Moon’s south pole.
Background
Chandrayaan 3 Landing Live Updates: Chandrayaan-3, India’s third lunar exploration mission, is set to land on the lunar south pole on August 23, 2023, at 6:04 pm IST, making India the first country to softly land a spacecraft on the Moon’s south pole. The entire country is full of “energy and excitement” because Chandrayaan-3’s landing will be a historic touchdown. The Indian Space Research Organisation (ISRO) made several changes to the Vikram lander in order to avoid the mistakes that occurred during the landing of Chandrayaan-2.
Chandrayaan-3 is almost identical to Chandrayaan-2, except that Chandrayaan-2 included an orbiter, but Chandrayaan-3 is not carrying an orbiter.
Chandrayaan-3 Landing Live: How Chandrayaan-3 Is Different From Chandrayaan-2
To ensure the success of Chandrayaan-3, ISRO has implemented a series of design and capability changes in the Vikram lander, aiming for strategic enhancements that increase the likelihood of a successful landing on the Moon's south pole. These modifications to Vikram's design are geared towards achieving a safe lunar landing. Key adjustments involve reinforcing the landing legs, enhancing sensors, optimizing the solar array, upgrading software capabilities, refining engine throttling, and fine-tuning engine configuration.
In contrast to Chandrayaan-2's Vikram, which was equipped with five 800 Newton engines, the Vikram lander of Chandrayaan-3 features four throttleable engines. ISRO has integrated a Laser Doppler Velocimeter for precision in guiding the autonomous landing manoeuvre. Additionally, the landing legs have been bolstered for increased strength, and a redundancy mechanism has been introduced to ensure autonomous landing even in the event of complete sensor and engine failure.
A throttleable engine offers the advantage of adjustable thrust. The incorporation of redundancy means that supplementary components, which may not serve a functional purpose, have been included to safeguard an autonomous landing should sensors and engines experience failure. The Laser Doppler Velocimeter is a specialized sensor integrated into the lander. It functions by gauging the frequency of light scattered by minuscule particles in a fluid to measure instantaneous fluid velocities. For Vikram, this sensor will determine the velocity of the lunar atmosphere.
The sensors onboard Chandrayaan-3's Vikram have been upgraded to be more advanced and responsive compared to those on Chandrayaan-2's lander. This enhancement equips the lander to make quicker and more informed decisions during the crucial landing phase.
