Chandrayaan-3: ISRO Completes Rocket Assembly, Final Tests Awaited for Launch

The Indian Space Research Organisation (ISRO) has completed the assembly of the Chandrayaan-3 rocket and is now preparing for the final round of tests before the anticipated launch. The spacecraft, including the indigenous lander module, propulsion module, and rover, is fully integrated, and the payload faring has also been completed. The launch is expected to take place between July 12 and July 19.

Here are the key points:

Key Points	Explanation
Rocket assembly status	Completed, with final tests pending
Expected launch date range	July 12 to July 19
Mission objectives	Develop and demonstrate technologies for interplanetary missions, analyze the lunar surface chemically, and perform experiments on the moon’s surface
Launch site	Satish Dhawan Space Centre, Sriharikota
Assembly location and preparations	UR Rao Satellite Centre (URSC) in Bangalore; assembly completed and sent to Sriharikota for launch
Chandrayaan programme background	Chandrayaan-1 launched in 2008 and successfully inserted into lunar orbit; Chandrayaan-2’s lander crash-landed on the moon’s surface in 2019 due to a software glitch

 

Rocket Assembly Completed:

The assembly of the Chandrayaan-3 rocket has been finished, and only the final round of tests remains.

Final Tests and Launch Schedule:

The rocket will undergo final testing before being moved from the vehicle assembly building to the second launchpad next week. The launch date is likely to be July 13, within the window of July 12 to July 19. ISRO Chairman S Somnath mentioned that they aim for an early launch within this timeframe.

Mission Objectives:

Chandrayaan-3 aims to develop and demonstrate new technologies required for interplanetary missions. The lander will possess the capability to softly land on a designated lunar site and deploy the rover, which will conduct in-situ chemical analysis of the lunar surface. Both the lander and the rover will carry scientific payloads to perform experiments on the moon.

Launch Site and Configuration:

Chandrayaan-3 will be launched from the Satish Dhawan Space Centre in Sriharikota. The propulsion module will carry the lander and rover configuration to a 100km lunar orbit.

Payload Assembly and Preparations:

The assembly process for Chandrayaan-3’s payloads started in May to ensure adherence to the planned launch date in July. The assembly was conducted at ISRO’s UR Rao Satellite Centre in Bangalore, followed by transportation to the Sriharikota space port for the launch.

Background on Chandrayaan Programme:

The Chandrayaan programme is an Indian space exploration initiative by the Indian Space Research Organisation (ISRO). It focuses on lunar exploration and includes various missions aimed at studying the Moon’s surface, composition, and its origin.

Here are some key points about the Chandrayaan programme:

1. Chandrayaan-1: The Chandrayaan-1 mission was launched on October 22, 2008. It was India’s first lunar mission and the first spacecraft to discover water molecules on the Moon’s surface. The mission also confirmed the presence of high amounts of helium-3, a potential fuel for future nuclear fusion.

2. Chandrayaan-2: Chandrayaan-2 was India’s second lunar mission and was launched on July 22, 2019. It consisted of an orbiter, a lander named Vikram, and a rover named Pragyan. The objective of the mission was to further explore the Moon’s surface and attempt a soft landing near the lunar south pole. However, the lander lost communication with ground control and the mission was partially successful, but it still provided valuable data.

3. Objectives: The Chandrayaan programme has several objectives, including mapping the lunar surface, studying the Moon’s mineralogy and geology, analyzing the lunar exosphere (thin atmosphere), and investigating the presence of water ice in the permanently shadowed regions of the Moon.
