The LVM-3 rocket carrying the Chandrayaan-3 spacecraft successfully lifted off from the Satish Dhawan Space Centre on July 14 at 14:35.

According to Indian Space Research Organisation (Isro) Chairman S Somanath in Delhi on August 7, the Chandrayaan 3 lunar mission is proceeding as planned towards a soft landing on the Moon later this month at a specific site, but backup plans have been set up to provide a second chance at making a landing in case any technical difficulties arise.

According to him, “our efforts are, however, such that a nominal landing happens on the same day at the same site as has been planned,” he told reporters in the capital.

According to Somanath, the spacecraft’s speed is being reduced in order to lower its orbit around the Moon. On August 6, Chandrayaan 3 was placed into an orbit measuring 170 km by 4,313 km. On August 9, it would be further lowered to an orbit of 100 km by 100 km.

The spacecraft’s sensors and other equipment will then be tested once more before being prepared to land on the surface of the South Pole region of the Moon on August 23 at 5:47 p.m. after descending to an orbit of 100 km x 30 km.

The Satish Dhawan Space Centre, SHAR, successfully launched the Chandrayaan-3 satellite at 14:35 on July 14 aboard LVM-3. The spacecraft is now engaged in two phases, the Earth Bound Phase and the Lunar Bound Phase, of orbital manoeuvres with the goal of entering the moon’s orbit. The spacecraft is now in the phase known as “Earth Bound.”

The components of Chandrayaan-3 include several electronic and mechanical subsystems designed to ensure a gentle and safe landing, including guidance and control systems, propulsion systems, and navigation sensors. There are also mechanisms for the rover’s release, as well as onboard electronics and antennas for two-way communication.

Chandrayaan-3 will cost a total of Rs 250 crore, as approved. Reaching the Moon’s orbit is anticipated to take close to 33 days from the launch date of July 14.

India would become the fourth country in the world to achieve such a monumental technological feat if the soft landing on the Moon’s surface was successful. The successful soft landing is expected to pave the way for further landing missions and other advancements in planetary exploration technology.

Chandrayaan-2’s soft landing on the moon was designed to take place over the course of several phases. A harsh landing was caused by greater velocity at touchdown that were beyond the designed capacity of the lander’s legs as a result of some unforeseen differences in the lander module’s performance.

Improvements to the lander to handle more dispersion, upgrades to the sensors, software, and propulsion systems, full-level redundancies, as well as in-depth simulations and additional testing, have all contributed to Chandrayaan-3 becoming more robust.

In contrast to Chandrayaan-2, Chandrayaan-3 has been built with the ability to handle a wide range of dispersion autonomously in order to accomplish a gentle and safe landing.
