Chandrayaan-3: India's Next Lunar Mission Set to Launch in mid July

India's space exploration program is set to make a significant leap with the upcoming launch of Chandrayaan-3, the country's third lunar mission. The Indian Space Research Organization (ISRO) has announced that the mission is scheduled to take off in mid-July, with the precise launch date yet to be finalized. Building upon the achievements of its predecessor, Chandrayaan-2, this mission aims to demonstrate India's end-to-end capability in safe landing and roving on the lunar surface. In this article, we will delve into the details of Chandrayaan-3, including its objectives, key components, and the innovative payloads that will be deployed.

Chandrayaan-3: A Follow-on Mission
Chandrayaan-3 is a follow-on mission to Chandrayaan-2, which captured global attention with its ambitious attempt to make a soft landing on the lunar surface. Although the previous mission faced a setback when the lander, Vikram, crash-landed, ISRO remains undeterred in its pursuit of lunar exploration. The primary objective of Chandrayaan-3 is to showcase India's ability to achieve a safe and gentle landing, as well as demonstrate the mobility of the rover on the moon's surface.

Launch Date and Location
The launch of Chandrayaan-3 is scheduled for mid-July, with officials indicating a potential launch window of July 12 or July 13. The launch will take place at the Satish Dhawan Space Centre in Sriharikota, which has been the primary launch site for India's space missions. This state-of-the-art facility, located in Andhra Pradesh, provides the necessary infrastructure and resources for successful space exploration endeavors.

The Landers and Rovers of Chandrayaan-3
Similar to its predecessor, Chandrayaan-3 will consist of a lander and rover configuration. The lander, named Vikram after Dr. Vikram Sarabhai, the father of the Indian space program, will play a crucial role in achieving a successful landing on the lunar surface. The rover, known as Pragyan, will be responsible for conducting a range of experiments and collecting valuable data.

Upgrades and Modifications
To enhance the chances of a successful mission, ISRO has made several upgrades and modifications to the lander and rover for Chandrayaan-3. The lander has been equipped with four motors, a reduction from the previous five motors used in Chandrayaan-2. Additionally, certain software adjustments have been made to ensure optimal performance. Despite these changes, ISRO has decided to retain the names Vikram and Pragyan for the lander and rover, respectively, paying homage to the previous mission's spirit of exploration.

Payloads for Scientific Exploration
Chandrayaan-3 will carry a suite of payloads to conduct scientific observations and gather crucial data from the moon's surface. These payloads are designed to provide scientists with new insights into the lunar environment and contribute to our understanding of the Earth-Moon system. Let's take a closer look at some of the key payloads onboard the mission:

1. Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA)
   The lander will be equipped with the RAMBHA payload, which aims to study the ionosphere and atmosphere of the moon. By analyzing the radio signals emitted by the moon, scientists can gain valuable insights into the composition and characteristics of its atmosphere.
2. Chandra's Surface Thermo physical Experiment (ChaSTE)
   Another important payload on the lander is ChaSTE, which focuses on studying the thermal properties of the lunar surface. By measuring the temperature variations, scientists can better understand the geological processes and composition of the moon's regolith.
3. Instrument for Lunar Seismic Activity (ILSA)
   ILSA is a payload specifically designed to detect and analyze seismic activity on the moon. By studying moonquakes and seismic waves, scientists can gain insights into the moon's internal structure and tectonic activity.
4. LASER Retroreflector Array (LRA)
   The lander will also carry the LASER Retroreflector Array, which is designed to reflect laser beams back to Earth. This payload enables precise measurements of the distance between Earth and the moon, contributing to our understanding of lunar dynamics and orbit.
5. Alpha Particle X-ray Spectrometer (APXS)
   The rover, Pragyan, will be equipped with the APXS payload, which enables the analysis of elemental composition on the lunar surface. By studying the distribution of elements, scientists can gain insights into the moon's geological history and its relationship with Earth.
6. LASER Induced Breakdown Spectroscope (LIBS)
   Another payload on the rover is LIBS, which utilizes laser-induced breakdown spectroscopy to analyze the chemical composition of lunar soil and rocks. This technique provides valuable data on the presence of different elements and minerals on the moon.
7. Spectro-polarimetry of HAbitable Planet Earth (SHAPE)
   A significant addition to Chandrayaan-3 is the SHAPE payload, which aims to study Earth's spectral and polarimetric measurements from the lunar orbit. This sophisticated equipment will provide valuable data on our home planet, enhancing our understanding of Earth's atmosphere and environment.

Objectives of Chandrayaan-3
ISRO has outlined three main objectives for the Chandrayaan-3 mission:

1. Safe and Gentle Landing: The mission aims to achieve a successful landing on the lunar surface, showcasing India's capability in precise and controlled landings.
2. Rover Mobility: Chandrayaan-3 will demonstrate the rover's ability to move on the moon's surface, allowing for extensive exploration and data collection.
3. In-Situ Scientific Observations: The mission will conduct scientific observations directly on-site, enabling researchers to gather valuable data about the moon's environment, composition, and geological processes.

Conclusion
With the upcoming launch of Chandrayaan-3, India is poised to continue its exploration of the moon and contribute to our understanding of Earth's natural satellite. The mission's objectives of achieving a safe landing, demonstrating rover mobility, and conducting in-situ scientific observations highlight India's commitment to pushing the boundaries of space exploration. With upgraded lander and rover configurations and a suite of innovative payloads, Chandrayaan-3 promises to be another milestone in India's space endeavor. As we eagerly await the launch in mid-July, the entire nation anticipates the success of this mission and the valuable insights it will bring.
