Chandrayaan-2 is India’s second lunar exploration mission, following the successful Chandrayaan-1 mission. It was launched by the Indian Space Research Organisation (ISRO) with the goal of expanding scientific understanding of the Moon. Here are key details about Chandrayaan-2:
Launch Date:
-
- Chandrayaan-2 was launched on July 22, 2019, from the Satish Dhawan Space Centre (SDSC) in Sriharikota, India.
Components:
-
- The mission comprised three main components: an orbiter, a lander named Vikram, and a lunar rover named Pragyan. The orbiter, which continues to orbit the Moon, carries scientific instruments to study the lunar surface and atmosphere.
- The Vikram lander was designed to make a soft landing on the lunar surface near the south pole, carrying instruments to study the lunar terrain.
- The Pragyan rover was intended to explore the lunar surface, analyze soil samples, and conduct experiments.
Mission Objectives:
-
- Chandrayaan-2 aimed to explore the southern polar region of the Moon, which was not extensively studied by previous missions.
- Scientific goals included studying the lunar topography, mineral composition, exosphere, and searching for water ice.
Soft Landing Attempt:
-
- While the orbiter successfully entered lunar orbit, the Vikram lander lost communication during its descent, and a planned soft landing attempt was unsuccessful. Despite the setback with the lander, the orbiter continued its scientific observations.
Orbiter’s Contributions:
-
- The Chandrayaan-2 orbiter continued to study the Moon’s surface and gather valuable data. It has made significant contributions to lunar science, including detecting lunar water and mapping lunar topography.
Chandrayaan-2 demonstrated India’s capability to launch and execute complex lunar missions. The orbiter continues to function well and has extended its mission life, providing ongoing data for lunar research. Despite the lander’s unsuccessful attempt, Chandrayaan-2 has paved the way for future lunar exploration missions by India and contributed to global lunar science efforts.
Chandrayaan-2 experienced a setback with the Vikram lander during its descent to the lunar surface. The mission had the ambitious goal of making a soft landing near the Moon’s south pole, a region that had not been explored in detail by previous missions. The incident occurred during the early hours of September 6, 2019, when Vikram was just about 2.1 kilometers above the lunar surface.
Here is a summary of the failure:
Communication Loss:
-
- During the final stages of the descent, as Vikram approached the lunar surface, communication with the lander was lost. The loss of signal occurred around 2.1 kilometers above the Moon.
Impact Analysis:
-
- Subsequent analysis suggested that the Vikram lander deviated from its intended trajectory and made a hard landing on the lunar surface. The impact site was identified, and efforts were made to analyze data from the orbiter to understand what happened.
Orbiter Continues Mission:
-
- Despite the setback with the lander, the Chandrayaan-2 orbiter continued its mission successfully. The orbiter, equipped with scientific instruments, has been orbiting the Moon and providing valuable data for lunar research.
Investigation:
-
- After the incident, ISRO initiated an investigation to understand the cause of the communication loss. The analysis involved reviewing telemetry data, simulations, and other relevant information to identify the factors that led to the failure.
While the soft landing attempt with the Vikram lander was not successful, Chandrayaan-2 as a mission was not considered a complete failure. The orbiter has continued to function well, and its extended mission life has allowed for ongoing lunar observations and scientific research. The experience gained from Chandrayaan-2 has contributed to ISRO’s knowledge and will likely inform future lunar exploration endeavors.
