Question

Write any 5 achievements of Chandrayan-1

Answer 1

Hint: Chandrayan -1, the country’s first-ever moon mission was the very first quest to the moon, which had put India on a pedestal of global space research.

Complete step-by-step answer:
1. The moon mission discovered the presence of water molecules in the lunar soil and the presence of ice at the polar regions .
2. The data collected through the microwave sensor of Chandrayaan 1 detected a good amount of past tectonic activity on the lunar surface.
3. The mineral content on the lunar surface was mapped through Moon Mineralogy Mapper and the presence of iron was confirmed ,along with changes in rock composition.
4. Understanding the thermal environment in lunar orbit which will help in achieving better performance in future.
5. Establishment of processors for collaboration with other space agencies.


Additional Information :
Extra points
1. Successful maneuvering for orbit around earth and moon.
2. First lunar mission with international participation to a large extent .
3. Successful operation to inject the Spacecraft into lunar orbit requiring high precision maneuver and planning.

More about chandrayan-1
The probe hit the moon’s crater which resulted in ejecting subsurface soil, which could be utilized for analysing lunar water ice. The location of the impact was named as ‘Jawahar Point’ as a symbolic gesture.

Interestingly, the terrain mapping camera on-board Chandrayaan 1, recorded images of the landing site of the US spacecraft Apollo 15, besides producing around 70, 000 three-dimensional images.
Signature of subsurface ice layers in permanently shadowed regions near the lunar north pole, preserved lava tube that may provide the site for future human habitation is some of them.

Note: Elaborative questions like this are better answered in points. Most evaluators prefer to the point answers.
