6.Chandrayaan-3 Right now

Learn all about Chandrayaan-3, India’s upcoming lunar mission aimed at furthering our understanding of the moon. Discover the mission objectives, launch plans, and the scientific advancements that Chandrayaan-3 promises, as we embark on this exciting journey of exploration and discovery.

Chandrayaan-3

The launch of Chandrayaan-3 took place on 14 July 2023, at 2:35 pm IST and lunar injection of 100 km circular polar orbit was completed successfully as part of phase one. The lander and rover are expected to land near the lunar south pole region on 23 August 2023.

Purpose:- Chandrayaan-3 Getting a lander to land safely and softly on the surface of the Moon. In-site scientific observation making scientific experiments on the chemical and natural elements, soil, water, etc. available on the surface of the Moon to better understand and practice the composition of the Moon. Interplanetary refers to the development and demonstration of new technologies required for missions between two planets.

The propulsion module will carry the lander and rover configuration till 100 km lunar orbit. It is a box-like structure with one large solar panel mounted on one side and a large cylinder on top (the Intermodular Adapter Cone) that acts as a mounting structure for the lander. In addition to the lander, the module carries a payload called Spectro-polarimetry of Habitable Planet Earth (SHAPE) to study the spectral and polarimetric measurements of Earth from the lunar orbit.

Lander:- The lander for Chandrayaan-3 will have only four throttle-able engines, unlike Vikram on Chandrayaan-2 which had five 800 Newtons engines with a fifth one being centrally mounted with a fixed thrust.[citation needed] Additionally, the Chandrayaan-3 lander will be equipped with a Laser Doppler Velocimeter (LDV).[23] The impact legs are made stronger compared to Chandrayaan-2 and increased instrumentation redundancy. ISRO is working on improving the structural rigidity and adding multiple contingency systems.[24]

The lander will carry three payloads:

  1. Chandra’s Surface Thermophysical Experiment (ChaSTE) will measure the thermal conductivity and temperature of the lunar surface.
  2. Instrument for Lunar Seismic Activity (ILSA) will measure the seismicity around the landing site.
    Langmuir Probe (LP) will estimate the plasma density and its variations.

Rover:

Chandrayaan-3 Rover
Chandrayaan-3 Rover Overview:

Six-wheeled design, Weight of 26 kilograms (57 pounds), Range of 500 meters (1,640 feet).
Scientific instruments including cameras, spectrometers, and a drill..
Expected lifespan of one lunar day (14 Earth days).
Communication with the lander and ground control team in India.

The Chandrayaan-3 Rover is expected to make a number of important scientific discoveries, including:

The composition of the lunar surface
The presence of water ice in the lunar soil
The history of lunar impacts
The evolution of the Moon’s atmosphere
The Chandrayaan-3 Rover is a major step forward for India’s space program. It is a testament to the country’s growing technological capabilities, and it is sure to make significant contributions to our understanding of the Moon.

Launch:
Chandrayaan-3 was launched on 14 July 2023, at 2:35 pm IST as scheduled, from Satish Dhawan Space Centre in Srihari Kota, Andhra Pradesh, India. The spacecraft has been effectively placed in the trajectory it will take to reach the moon. The distance between the Earth and the moon is approximately 384,400 kilometers. It is anticipated that the Chandrayaan-3 mission will achieve a soft landing on the lunar South Pole region on either 23 or 24 August.

Choosing the month of July for the launch of Chandrayan 3 was a special move because of a calculation made by ISRO regarding the closeness of Earth and Moon

Funding of Chandryaan-3:
In December 2019, it was reported that ISRO requested the initial funding of the project, amounting to ₹75 crore (US$9.4 million), out of which ₹60 crore (US$7.5 million) will be for meeting expenditure towards machinery, equipment and other capital expenditure, while the remaining ₹15 crore (US$1.9 million) is sought under revenue expenditure head.

Confirming the existence of the project, ISRO’s former chairman K. Sivan stated that the estimated cost would be around ₹615 crore (equivalent to ₹721 crore or US$90 million in 2023).
