Chandrayaan-3 | Vikram generated halo on landing on moon


Vikram Lander of . Chandrayaan-3 might be seen resting on the floor of the moon on this picture clicked with Pragyan Rover’s navigation digicam.

Chandrayaan-3’s lander module, Vikram, had generated an ‘ejecta halo’ on the lunar floor whereas making the historic landing on the south pole of the moon on August 23. 

According to a brand new examine, Vikram raised lunar mud and generated a vibrant patch round itself when it landed on the moon.

”Chandrayaan-3 Results: On August 23, 2023, because it descended, the Chandrayaan-3 Lander Module generated a spectacular ‘ejecta halo’ of lunar materials. Scientists from NRSC/ISRO estimate that about 2.06 tonnes of lunar epi regolith have been ejected and displaced over an space of 108.4 m² across the landing web site”, ISRO posted on X (previously Twitter).

These findings have been printed in an article titled Characterisation of Ejecta Halo on the Lunar Surface Around Chandrayaan-3 Vikram Lander Using OHRC Imagery, within the Journal of the Indian Society of Remote Sensing on October 26.

“The Vikram lander of the Chandrayaan-3 mission landed near the south pole of the moon on August 23. During the action of descent stage thrusters and the consequent landing, a significant amount of lunar surficial epi regolith material got ejected, resulting in a reflectance anomaly or ejecta halo”, states the summary of the article, authored by Swati Singh, Prakash Chauhan, Priyom Roy, Tapas R. Martha and Iswar C. Das from ISRO’s National Remote Sensing Centre (NRSC), Hyderabad.

The authors added that they in contrast the pre- and post-landing high-resolution panchromatic imagery from Orbiter High-Resolution Camera (OHRC) of the Chandrayaan-2 orbiter, acquired hours earlier than, and after the landing occasion, and characterised this ejecta halo as an irregular vibrant patch surrounding the lander.

“From the mapped and classified, uncorrelated ejecta halo pixels, an approximate areal extent of 108.4 m2 is estimated to have been covered by lunar epi regolith ejecta displaced due to the landing sequence of the Vikram lander. Further, using empirical relations, we estimate that approximately 2.06 tonnes of lunar epi regolith were ejected due to the landing event,” the authors added.

India turned the fourth nation to efficiently land a spacecraft on the moon, and the primary nation to the touch down within the polar area when the Chandrayaan-3’s lander module, with the rover in its stomach, efficiently made a tender landing on the lunar floor on August 23.

Since landing on the moon, Vikram and Pragyan Rover have carried out many in-situ measurements, like affirmation of the presence of sulphur within the area, and detecting the presence of minor parts, amongst different issues.

Vikram additionally achieved a big milestone, because it efficiently undertook a hop experiment when the lander — on command — fired the engines, elevated itself by about 40 cm, and landed safely at a distance of 30-40 cm away.

The lander and the rover went to sleep after the top of 1 lunar day (14 Earth days). Efforts to wake them up haven’t been profitable to this point.
