Which of the following best describes Ejecta halo, which was recently ...
Recently, the Indian Space Research Organisation (ISRO) revealed that the "Chandrayaan-3 Lander Module generated a spectacular 'ejecta halo' of lunar material.
- The Vikram lander of the Chandrayaan-3 mission landed near the south pole of the moon.
- 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”.
- Scientists from ISRO estimate that about 2.06 tonnes of lunar epi regolith were ejected and displaced over an area of 108.4 m² around the landing site.
- Ejecta halo is an irregular bright patch surrounding the lander.
- Significance:
- This discovery sheds light on the behaviour of lunar materials during such events.
- It opens up new avenues for research and understanding lunar geology.
What is Regolith?
- It is a blanket of unconsolidated, loose, heterogeneous superficial deposits covering solid rock.
- Epiregolith is lunar rocks and soil, or regolith, or Moon dust.
Hence option (a) is the correct answer.
