Chandrayaan-3, the spacecraft launched on July 14, is now approaching the moon's surface after completing about two-thirds of its journey. Over the past three weeks, ISRO has skillfully adjusted its orbit through five maneuvers, gradually distancing it from Earth. The "slingshot move" executed on August 1 was a significant step that redirected the craft towards its lunar destination.
Tomorrow, a crucial maneuver called the Lunar Orbit Injection (LOI) is scheduled for approximately 7 pm on August 5. This intricate operation will be executed when Chandrayaan-3 is closest to the moon's surface, known as perilune.
ISRO has confirmed that India's third lunar mission is in excellent condition, and they plan to attempt a soft landing on the moon's surface on August 23.
The entire journey from launch to entering the moon's orbit will take around 33 days. Once landed, the spacecraft will be operational for one lunar day, equivalent to roughly 14 Earth days.
Chandrayaan-3 is equipped with an array of electronic and mechanical subsystems to ensure a safe and gentle landing. These include navigation sensors, propulsion systems, guidance, control mechanisms, two-way communication antennas, and other onboard electronics. Moreover, the spacecraft features mechanisms for releasing a rover for surface exploration.
The mission's primary objectives are to achieve a secure and soft landing on the moon, deploy the rover for surface exploration, and conduct in-situ scientific experiments. The approved budget for Chandrayaan-3 is Rs. 250 crores, exclusive of the launch vehicle's cost.
