Chandrayaan 3: Launch Date, Payloads, and More Specifications, Everything You Need to Know About

Discover detailed information about the launch date, payloads, and additional specifications of Chandrayaan 3, India’s upcoming lunar mission set to be launched on 14 July 2023.

India’s third lunar mission, Chandrayaan 3, is being carried out by the Indian Space Research Organisation (ISRO). According to a tweet from ISRO, the mission is scheduled to commence on 14 July 2023. The primary goal of this mission is to achieve the successful deployment of a lander and rover on the lunar surface in the lunar highlands near the South Pole of the moon by August 2023.

Chandrayaan 3, an ISRO mission scheduled for August 2023, aims to demonstrate the entire process of landing and maneuvering on the lunar surface. According to NASA archives, its main objective is to deploy a lander and rover near the Moon’s south pole highlands, showcasing their capabilities in landing and roving. Additionally, the mission will conduct various scientific measurements both on the lunar surface and from orbit.

Chandrayaan 3: When is the Launch Date?

The ISRO has announced that the launch for India’s first attempt to softly land a spacecraft on the lunar surface since the Chandrayaan 2 mission in 2019 is scheduled for July 14, 2023. The mission will commence from Satish Dhawan Space Centre, Sriharikota.

According to ISRO Chairman S.Somanath, the initial launch date was set for July 13 and had a window until July 19, but it was later rescheduled to July 14 at 2:35 PM IST. The Chandrayaan-3 has been transported to Satish Dhawan Space Centre for its final assembly.

What are the components of Chandrayaan?

Chandrayaan 3 is comprised of a Lander Module (LM), a Propulsion Module (PM), and a rover. The LM’s main task is to achieve a gentle landing on the moon’s surface, while the PM will handle propulsion and attitude control throughout the mission. The rover, on the other hand, will be utilized for lunar surface exploration and gathering scientific information.

According to ISRO, the components of Chandrayaan-3 include an indigenous Lander module (LM), Propulsion module (PM), and a Rover. The main goal of this mission is to develop and showcase new technologies essential for interplanetary missions.

Chandrayaan 3 will possess the ability to gently land at a designated location on the moon and release the Rover, which will conduct on-site chemical analysis of the lunar surface while it moves. Both the Lander and the Rover contain scientific equipment to perform experiments on the moon’s surface. Additionally, the primary role of the PM is to transport the LM from its launch vehicle injection to its ultimate lunar orbit of 100 km in a circular polar trajectory, and then detach from the LM.

What are the Payloads of Chandrayaan 3?

The ISRO has listed several payloads for the lander, including the Chandra s Surface Thermophysical Experiment (ChaSTE) for measuring thermal conductivity and temperature, the Instrument for Lunar Seismic Activity (ILSA) for monitoring seismicity at the landing site, and the Langmuir Probe (LP) for estimating plasma density and its changes. Additionally, a passive Laser Retroreflector Array provided by NASA will be used for lunar laser ranging studies. This information pertains to Chandrayaan 3.

“Rover payloads: Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of landing site.”

Here are the terms described briefly: 

Lander Payload:

• ChaSTE: Chandra’s Surface Thermophysical Experiment. This instrument will measure the thermal conductivity and temperature of the lunar surface.
• ILSA: Instrument for Lunar Seismic Activity. This instrument will measure the seismicity of the lunar surface. In its essence, it will measure how much the surface of the moon shakes. 
• Langmuir Probe: This instrument will estimate the plasma density and its variations in the lunar ionosphere.
• Passive Laser Retroreflector Array: This array will be used for lunar laser ranging studies. It will be used to measure the distance between the Earth and the Moon.

Rover Payloads:

• Alpha Particle X-ray Spectrometer: This instrument will identify the elemental composition of the lunar surface.
• Laser Induced Breakdown Spectroscopy: This instrument will identify the chemical composition of the lunar surface.

The primary goal of the mission is to study the lunar surface and collect data on the moon’s geology and composition. These instruments will aid scientists in learning more about the composition, seismicity, and environment of the Moon.

This information will aid in better understanding the Moon’s history and evolution, as well as in identifying potential resources for future human missions to the Moon.

Finally, the launch of Chandrayaan 3 marks a significant milestone in India’s space program. It is a testament to the ISRO team’s hard work and dedication, and it will aid in our understanding of the moon.
