Chandrayaan-3: Everything You Need to Know About India’s Upcoming Moon Mission

Upam Bikash

India is preparing for its next lunar adventure, Chandrayaan-3, which is set to launch on July 14, 2023. The mission will test the ability of the Indian Space Research Organisation (ISRO) to land softly on the Moon and send a rover to explore its surface. Here are some important details and highlights of Chandrayaan-3 that you should know.

What is Chandrayaan-3?

Chandrayaan-3: Everything You Need to Know About

Chandrayaan-3 is a sequel to Chandrayaan-2, which was launched in July 2019 but could not land on the Moon due to a software error. Chandrayaan-3 will have a lander and a rover similar to Chandrayaan-2, but no orbiter. Instead, the mission will use a propulsion module as a relay station between the lander and the Earth.

The propulsion module will also carry a payload called Spectro-polarimetry of Habitable Planet Earth (SHAPE), which will study the light and color of Earth from the lunar orbit.

What are the goals of Chandrayaan-3?

The main goal of Chandrayaan-3 is to show the soft landing skill of ISRO and study the lunar surface with a rover. The mission will also prepare for future partnerships with Japan on a joint Lunar Polar Exploration Mission planned for 2025.

The lander and rover of Chandrayaan-3 will have four scientific payloads each, which will do various experiments and measurements on the Moon. Some of the payloads are:

  • Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA), which will study the electric and magnetic fields near the lunar surface.
  • Chandra’s Surface Thermo physical Experiment (ChaSTE), which will measure the heat flow and temperature change of the lunar soil.
  • Instrument for Lunar Seismic Activity (ILSA), which will detect and analyze quakes and other movements on the Moon.
  • Laser Retroreflector Array (LRA), which will act as a passive target for laser distance measurement from Earth or other spacecraft.
  • Alpha Particle X-Ray Spectrometer (APXS), which will find out the elements present in the lunar rocks and soil.
  • Laser Induced Breakdown Spectroscope (LIBS), which will do on-the-spot chemical analysis of the lunar surface by burning it with a laser beam.

Where will Chandrayaan-3 land?

Chandrayaan-3 will aim for a landing site near the south pole of the Moon, which is very interesting for science because of the water ice and other materials in dark craters. The main landing site is a 4 km x 2.4 km area located at 69.367621 S, 32.348126 E. The lander will separate from the propulsion module after reaching a round orbit of 100 km above the Moon and do a series of steps to land softly.

The rover, named Pragyan, will be inside the lander and will come out after landing. The rover will have a mass of 26 kg and a power of 50 W. It will be able to move at a speed of 1 cm per second and cover a distance of up to 500 m during its mission life of one lunar day (about 14 Earth days).

How can you follow Chandrayaan-3?

You can follow Chandrayaan-3 on ISRO’s Official website where you can find updates, images, videos and other information about the mission. You can also watch the live launch and landing events on ISRO’s YouTube channel or on other media platforms.

You can also support Chandrayaan-3 by sending your messages and wishes to ISRO through their social media handles or by using the hashtag #Chandrayaan3.

Chandrayaan-3 is an exciting and challenging mission that shows India’s talent in space exploration and science. Let us cheer for ISRO and wish them all the best for a successful launch and landing of Chandrayaan-3!
