Scott Tilley, space enthusiast and expert in Chandrayaan-3 and Luna-25, discusses ISRO's success, the mystery behind Luna-25, challenges of finding evidence, and the limitations of the Deep Space Network.
The success of India's Chandrayaan-3 mission showcases the country's efficiency and practicality in lunar exploration, emphasizing the importance of precision landing and throttleable engines for lunar landers.
The lack of transparency and independent verification of Russia's Luna-25 mission raises concerns about its credibility and adherence to principles of open exploration, highlighting the need for transparency in space missions.

Chandra and 3 Lunar Mission
The Indian mission, Chandra and 3, successfully landed on the moon. The mission was carried out transparently, with minor discrepancies like rounding numbers for timing purposes. The spacecraft was oriented to maximize power generation and demonstrated the Indian Space Program's efficiency and practicality. The mission, conducted on a budget, showcased precision landing and the importance of throttleable engines for lunar landers. The spacecraft's solar panels were carefully positioned to optimize power generation. The mission's success demonstrated India's calculated and careful approach to lunar exploration.
Luna 25 Lunar Mission
The status of the Russian Luna 25 mission remains unclear. Despite claims from the Russian government, there is no independent evidence to confirm its arrival at the moon. The last independent observation of the mission was near Earth, and subsequent communication attempts have been unsuccessful. This raises questions about whether Luna 25 actually reached its intended destination. The lack of transparency and independent verification is concerning, as it goes against the principles of open exploration and undermines the mission's credibility.
Deep Space Network Challenges
The Deep Space Network (DSN) is facing challenges in terms of infrastructure, budget, and availability. During the Artemis 1 mission, the DSN experienced strain due to the cubesats flown alongside the main mission. The DSN's limited assets and high demand from various missions can lead to inefficiencies and conflicts in scheduling. To address these issues, alternative approaches could be considered, such as using smaller aperture assets for certain missions, developing dedicated lunar communication networks, and encouraging commercial companies to build their own communication infrastructure. These measures would help alleviate the strain on the DSN and ensure efficient and reliable communication for future deep space missions.

ISRO on X: “Beyond Borders, Across Moonscapes: India's Majesty knows no bounds!. Once more, co-traveller Pragyan captures Vikram in a Snap! This iconic snap was taken today around 11 am IST from about 15 m. The data from the NavCams is processed by SAC/ISRO, Ahmedabad.”
Scott Tilley 🇺🇦 on X: “I have been asked repeatedly about #Luna25. Thus far I have no independent observations of the mission to share. That is not without extensive trying to observe it. So why am I not detecting anything? 🧵⬇️”
