At the same time, we are pleased to give you information regarding  ISRO to launch Chandrayan – 3 on July 14: India’s third lunar exploration mission and other facts. To know more, please keep reading the entire article till the end.

About ISRO to Launch Chandrayaan 3 on July 14: India’s Third Lunar Exploration Mission

Chandrayaan-3, India’s third lunar exploration mission, will launch on July 14 at 2.35 p.m. from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, based on a previous announcement by ISRO Director S Somanath and if all goes well, it will land on the moon on August 23. The equations used to determine the date depend on when the moon will rise in the sky, but if it is delayed, we will have to postpone the landing until September.

India’s third Chandrayaan moon mission aims to send a rover to explore and conduct scientific experiments on the moon’s surface, following Chandrayaan-2’s difficulties. With a budget of around Rs. 615 crore, the mission advances India’s lunar exploration and science advancements.

Chandrayaan-3 mission investigates the lunar surface electromagnetic environment, elemental composition, seismicity, and thermophysical properties, completing tests to survive vibrations during launch.The Chandrayaan-3 mission is the follow-up to Chandrayaan-2, which was launched on July 22, 2019, and spent 48 days travelling to the moon. Vikram, a lunar lander, crashed on the moon’s surface on September 6, 2019, ending the mission.

The Chandrayaan-3 mission’s lander has been redesigned with four motors and software modifications, replacing the previous lander and rover. ISRO’s decision on keeping the names is unknown.Chandrayaan-3’s SHAPE instrument upgrades payload for analyzing lunar orbit Earth spectral and polarimetric readings.

ISRO has defined three primary aims for the Chandrayaan-3 mission, according to reports. These objectives include landing safely and gently on the Moon, demonstrating the rover’s mobility on the lunar surface, and conducting on-site scientific studies.

The heaviest Geosynchronous Launch Vehicle (GSLV) will be used to launch the Chandrayaan-3 mission. The 3,900-kilogram spacecraft will be packed into the payload fairing of the GSLV Mk-III rocket, known as the “Bahubali” of rockets, and will launch from the Satish Dhawan Space Centre in Sriharikota to escape Earth’s gravity.

The GSLV-Mk III rocket, used for the Chandrayaan-2 launch, has a liquid core stage, high-thrust cryogenic upper stage, and two solid strap-on boosters, capable of launching 8,000 kg payloads into low Earth orbit and GSAT series satellites.

What is Chandrayaan-3

 A continuation of Chandrayaan-2 aims to showcase India’s lunar exploration capabilities and gather valuable data. It uses scientific instruments to study the lunar environment, including thermophysical properties, seismicity, plasma environment, and elemental composition near the landing site.

The Moon’s Science and it’s Research

Chandrayaan-3 mission focuses on the “Science of the Moon” with the lander and rover instruments, while an experimental instrument analyzes Earth’s spectro-polarimetric signatures from lunar orbit.

Goals of the mission

Chandrayaan-3 lander module performs a soft landing, deploys the rover, and conducts in-situ chemical analysis on the lunar surface.

Propulsion module’s role

The propulsion module transports the lander module to a circular polar orbit above the lunar surface, separating from it and carrying a scientific payload.

Key points of Chandrayaan 3

  • S. Somanath is the Indian Space Research Organization’s chairman, 
  • Bengaluru is the organization’s headquarters.
  • On August 23 or 24, the Chandrayaan-3 lander will be scheduled to soft-land.
  • The primary goal of ISRO was to make Chandrayaan-3’s landing safe and soft.
  • After landing, the rover will emerge. It has six wheels.
  • India’s Third Lunar Mission, Chandrayaan-3, Builds on the Legacy of Chandrayaan-1 and Chandrayaan-2
  • Successful Moon Landing and Rover Deployment Are Goals of Chandrayaan-3
  • The countdown to the July 14, 2023 launch of Chandrayaan-3 has begun.
  • Budgeted at $615 million for an ambitious lunar mission, Chandrayaan-3
  • Exploring the Moon: Chandrayaan-3 to Examine the Moon’s Characteristics and Makeup
  • Chandrayaan-3, the follow-up mission to Chandrayaan-2, is continuing in its predecessors’ footsteps.
  • Chandrayaan-3 Is Expected to Offer Important Insights for Unlocking Lunar Secrets

Chandrayan -3 budget 

India’s Chandrayaan 3 budget, estimated at ₹615 crores, demonstrates its commitment to lunar exploration. The budget includes cutting-edge spacecraft, rocket technology, and rigorous testing procedures, aiming to push the boundaries of scientific innovation.
