WESAT was launched aboard the PSLV-C58/XPoSAT Mission as one of the secondary payloads on 1st January, 2024. WESAT aims to inspire more women to participate in the field of aerospace engineering and satellite technology. The mission is a significant milestone in promoting gender diversity and inclusion in the space sector.

Q10. The location of the planned prime landing site for Vikram Lander on Chandrayaan-2 was SLS54, which is located at 70.9S and 22.8E on the Moon. Consider the following statements regarding the selection of the potential landing site.
(i) Visible to Earth for radio communication.
(ii) Water ice has been mapped at the site earlier by Lunar Reconnaissance Orbiter mission.
(iii) Local terrain features such that they dont shadow the site for long durations.
Which of the following statements above is/are correct?
1. ii and iii
2. i and iii
3. i, ii and iii
4. iii only
Answer: Option 2
Solution: The correct answer is Option 2. Statement i: The planned landing site for Vikram Lander was designed to ensure uninterrupted radio communication with Earth, which is crucial for the success of the mission. Statement iii: The selection of the site took into account local terrain features, ensuring that they do not shadow the site for long durations, which could impact operations and power generation. The sites location in the polar region helps in maximizing scientific exploration opportunities, including research on water ice and lunar geology. The mission aimed to achieve a soft landing near the Moons South Pole, a previously unexplored region, marking a significant milestone in space exploration. Statement ii: While water ice has been mapped at the Moons South Pole by missions such as NASAs Lunar Reconnaissance Orbiter LRO, there is no conclusive evidence that it was specifically mapped at the SLS54 site. The Moons South Pole is of great interest to scientists due to the presence of permanently shadowed regions that may harbor water ice, which could be a resource for future lunar missions. Chandrayaan-2: It was Indias second lunar exploration mission, developed by ISRO, comprising an orbiter, a lander Vikram, and a rover Pragyan. Lunar Reconnaissance Orbiter LRO: This NASA mission has been instrumental in mapping the Moons surface and identifying potential resources such as water ice, contributing to the selection of landing sites for future missions. Challenges of Lunar South Pole Landing: The regions rugged terrain and low sunlight angles make landing and operations challenging, requiring precise planning and robust technology.
