Chandrayaan-3: India’s Next Lunar Mission
Chandrayaan-3: India’s Third Lunar Mission
Chandrayaan-3 is India’s upcoming lunar mission. The spacecraft was launched from Satish Dhawan Space Center in Sriharikota, India, on July 14, 2023, at 5:05 AM EDT (or 2:35 PM local time). On August 23, 2023, at 8:33 AM ET (or 6:03 PM local time in India), Chandrayaan-3 successfully landed near the south pole of the Moon. This mission is under the supervision of the Indian Space Research Organization (ISRO).
The three primary objectives of Chandrayaan-3 are:
- Safe Surface Landing: The first goal of Chandrayaan-3 is to achieve a safe landing on the lunar surface.
- Demonstrate Rover Operations: The second objective is to demonstrate rover operations.
- Conduct On-Site Scientific Experiments: The third goal is to perform scientific experiments on-site.
The spacecraft includes a propulsion module that is used to transport the Chandrayaan-3 Vikram (lander) and the Pragyan (rover) to the Moon’s south pole. This module then entered a nearly 60-mile (100-kilometer) circular orbit around the Moon. The lander module subsequently separated and attempted a soft landing on the surface, which was successfully achieved on August 23, 2023. The lander and rover will collect scientific data on the lunar surface for approximately 14 Earth days.
- Mission Overview:
- Chandrayaan-3 is an ambitious space mission by the Indian Space Research Organization (ISRO).
- Its primary objective is to explore the Moon and conduct scientific experiments.
- Unlike its predecessor, Chandrayaan-2, which included both an orbiter and a lander-rover combination, Chandrayaan-3 focuses solely on the lander-rover component.
- Launch and Journey:
- On July 14, 2023, Chandrayaan-3 was launched from the Satish Dhawan Space Center in Sriharikota, India.
- It traveled through space to reach the Moon.
- The spacecraft carried the Vikram lander and the Pragyan rover.
- Landing on the Moon:
- On August 23, 2023, the lander successfully touched down near the south pole of the Moon.
- This achievement marked a significant milestone for India’s lunar exploration program.
- The lander is equipped with scientific instruments to study the lunar surface.
- Duration:
- The lander and rover are expected to operate for approximately 14 Earth days (which corresponds to one lunar day).
- During this time, they will collect valuable data about the Moon’s composition, surface features, and environment.
Remember, Chandrayaan-3 represents India’s continued commitment to space exploration and scientific discovery.
Chandrayaan-3, India’s third lunar mission, is equipped with several scientific instruments to explore the Moon’s surface and conduct valuable research. Here are the key instruments onboard:
- Lander Instruments:
- Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA): This instrument studies the Moon’s ionosphere and atmosphere.
- Chandra’s Surface Thermo-physical Experiment (ChaSTE): It measures thermal conductivity and temperature on the lunar surface.
- Instrument for Lunar Seismic Activity (ILSA): ILSA detects moonquakes, providing insights into lunar seismic occurrences.
- Laser Retroreflector Array (LRA): LRA assists in precise distance measurements.
- Rover Instruments:
- Alpha Particle X-Ray Spectrometer (APXS): The rover uses APXS to study the local elemental composition of the lunar surface.
- Laser Induced Breakdown Spectroscope (LIBS): LIBS analyzes surface materials by inducing laser-induced breakdown.
- Propulsion Module Instruments:
- Spectro-polarimetry of Habitable Planet Earth (SHAPE): This instrument is part of the propulsion module.
- Other Details:
- Other Details:
- Mission Life: Chandrayaan-3’s lander and rover are designed to operate for approximately 14 Earth days (equivalent to one lunar day).
- Communication: The lander communicates with the Indian Deep Space Network (IDSN), and the rover communicates with the lander.
- Lander Sensors: These include various sensors for navigation, hazard detection, and altitude measurement.
- Lander Actuators: Reaction wheels and propulsion systems are used for maneuvering.
