CHANDRAYAAN-3. The Indian space mission ended 15 days after its arrival on the Moon, A look back at the discoveries and results of a mission already carried out historical.
On August 23, 2023, India struck hard by landing its first space probe on the Moon, becoming the fourth in the world. me nation &agrav; achieve this feat. The landing of Chandrayaan-3 took place in the region of the South Pole of the Moon, a region that is difficult to access and highly coveted. eacute;e of our natural satellite. After two weeks of exploration and scientific measurements, the Vikram lander and the Pragyan rover had been completed. put to sleep &agrav; the approach of lunar night.
During his short period of activity &agrav; On the surface of the Moon, Pragyan was not idle. Indeed, the rover had time to travel around a hundred meters, take a few photographic shots, take temperature measurements and ;eacute;rent analyzes of the soil which revealed some surprises for scientists. The precious data thus collected was used for the purposes of the collection. transmitted à the mission's scientific team before the machines are put on standby. Let's take stock of the progress of the mission and its outcomes. covered.
Who discovered the Chandrayaan-3 mission on the Moon ?
The multiple measuring instruments equipped with the lander and the rover of the Chandrayaan-3 mission made it possible to carry out some analyzes of the lunar soil. The discoveries thus made represented a considerable scientific contribution and have been the opportunity for a few surprises.
À Using the probe and thermal sensors that equip the lander, the mission's scientists discovered that the temperature dropped very sharply. quickly in the first centimeters of the lunar soil. This temperature thus rose from 60°C on the surface to 60°C at the surface. -10°C à 8 centimeters deep.
The Pragyan rover had also studied the composition of the lunar soil, thus confirming for the first time the presence of sulfur which could be the result of lunar activity. past tectonics of the Moon. The measurements carried out also indicated the presence of other compounds such as aluminum, iron, chromium as well as titanium.
What are the photos taken by the Chandrayaan-3 probe?
As the space probe orbited the Moon before landing, Chandrayaan-3 captured, With the help of his camera, a series of photos published by the Indian Space Agency. We can see the hidden side of the Moon and its multiple craters:

Shortly after his first laps on the lunar soil, Pragyan had immortalizedé its first crater, a dangerous relief 4 meters in diameter. The machine had to turn back to take a safer route.

Chandrayaan-3 is a space probe designed by the Indian Space Agency, ISRO, whose launch took place on 14 July 2023. Consisting of a lander which landed gently &agrav; the surface of the Moon and a rover that descended from the landing module to the Moon. Using an inclined ramp, this probe achieved several discoveries during its mission which began in August 2023.

To lead à its mission, the Chandrayaan-3 probe embarked various instruments. The lander was notably equipped with a camera, a seismometer to study the surface of the Moon as well as several tools allowing it to carry out certain measurements and to analyze the lunar atmosphere. For its part, the rover had two spectroscopes allowing it to ;éstudy the chemical nature of lunar soil as well as several cameras. This probe succeeded Chandrayaan-2 which crashed into the surface of the Moon in July 2019.
Wù had landed the Chandrayaan-3 probe on the Moon?
For the landing of the Chandrayaan-3 probe, ISRO had selected a site that lies between the craters Manzinus C and Simpelius N. This place is located not far from the South Pole of the Moon, a very rugged region dotted with craters and reliefs where the maneuver is particularly difficult at high altitudes. achieve. Before reaching its landing zone, the probe had achieved several orbits around the Moon and then began its descent.
What were the objectives of the Chandrayaan-3 mission?
The Vikram lander, which means "valor” in Sanskrit, was charged with to study the surface of the Moon. To do this, he had to take an interest in its seismic and thermal characteristics, its geology as well as the gases that make up its thin atmosphere. For its part, the Pragyan rover meaning "wisdom" in Sanskrit, weighing 26 kg, had to concentrate his efforts on the study of the composition of the soil from a point of view chemical and mineralogical.
