The Indian Space Research Organization (ISRO) said on Friday, October 27 that when Vikram Lander landed on the lunar surface from Chandrayaan, it had blown away about 2.06 tonnes of lunar epiregolith i.e. moon dust. Due to this, a spectacular ejecta halo was formed there. This cloud of dust raised at the landing point (Shiv Shakti Bindu) had spread over an area of about 108.4 square meters. When Vikram Lander of Chandrayaan-3 landed on the surface of the Moon on 23 August 2023, an amazing incident happened. Vikram had removed more than 2 tons of dust and rock fragments from the lunar surface. This created a bright area around the lander. Scientists had also expected this. As Vikram came closer and landed on the lunar surface, it activated its last stage thrusters. Due to this, a large amount of soil or rather the upper surface was removed from the moon’s surface. Scientists are now calling this phenomenon ‘ejecta halo’.
ISRO has shared a document on In which this ejecta appeared as a bright patch around the halo lander.
Vikram Lander, sent to the Moon through India’s Chandrayaan-3 mission, landed near the Moon’s south pole on August 23. After this, Rover Pragyan had sent information related to temperature and minerals on the surface of the Moon.
This information was received from Chandrayaan-3
ILSA payload records earthquake on lunar surface: On August 31, ISRO reported that the Instrument of Lunar Seismic Activity (ILSA) payload mounted on Chandrayaan-3’s Vikram lander has recorded the natural phenomenon of earthquake on the lunar surface. This earthquake occurred on 26 August. ISRO said that investigation into the source of the earthquake is ongoing. LIBS payload confirmed sulfur on the Moon: The second observation sent on August 28 also revealed the presence of sulphur, aluminium, calcium, iron, chromium, titanium on the South Pole of the Moon. There are also manganese, silicon and oxygen on the surface, the search for hydrogen is ongoing.
Pragyan Rover changed its route after seeing a 4 meter crater
On August 27, a 4 meter diameter crater appeared in front of Rover Pragyan. This crater was 3 meters ahead of the rover’s location. In such a situation, the rover was given the command to change the path. Even before this, Pragyan had passed through a small crater about 100 mm deep.
Plasma found on surface, but less dense
The Radio Anatomy of Moon bound Hypersensitive Ionosphere and Atmosphere-Langmuir Probe (RAMBHA-LP) aboard the lander Vikram has discovered plasma at the Moon’s south pole, although it is less dense (sparse).
First observation of Vikram Lander – Temperature around 50 degrees on the surface: ChaSTE payload mounted in Vikram Lander of Chandrayaan-3 has sent the first observation related to the temperature of the Moon. According to ChaSTE i.e. Lunar Surface Thermophysical Experiment, there is a lot of difference in the temperature on the surface of the Moon and at different depths.
This was India’s third mission to the moon, water was discovered in the first mission.
Chandrayaan-1 was launched in 2008. In this, a crash landing of a probe was done in which water was found on the moon. Then in 2019, Chandrayaan-2 reached close to the moon, but could not land. Chandrayaan-3 landed on the moon on 23 August 2023. Chandrayaan-3 also sent the message of reaching the moon safely. Said- ‘I have reached my destination.’
Have Vikram and Pragyan slept forever: No signal sent yet
It’s been almost two months since Vikram Lander and Pragyan Rover landed on the Moon, but both have not yet sent any signal to wake up from sleep mode. What have they achieved so far and what is left; In this position, will Chandrayaan-3 be called completely successful or not?
