ISRO developing tech to keep lunar landers alive for 200 days: Chairman Narayanan
Bengaluru, June 13
India is developing technology that could enable future lunar landers to survive on the Moon for up to 200 days, a significant advancement from the 14‑day operational lifespan achieved by the Chandrayaan‑3 mission, ISRO Chairman V. Narayanan said.
Speaking about the ongoing research in Bengaluru on Saturday, Narayanan said the Indian Space Research Organisation (ISRO), in collaboration with the Department of Atomic Energy (DAE), was working to overcome one of the biggest challenges in lunar exploration - surviving the harsh and prolonged lunar night.
Narayanan said the effort was focused on developing advanced artificial heating systems capable of protecting spacecraft components during the extremely low temperatures experienced on the Moon after sunset.
On August 23, 2023, India created history by becoming the first country to successfully land a spacecraft near the Moon's south pole through the Chandrayaan‑3 mission. However, the Vikram lander remained operational for only one lunar day, or about 14 Earth days, as it relied on solar energy to generate power.
Once the lunar night began, the absence of sunlight and temperatures plunging to extremely low levels made it impossible for the spacecraft's electronic systems to continue functioning.
Narayanan said ISRO and the Department of Atomic Energy were working on artificial heaters, and if successful, future landers could survive for 100 to 200 days instead of only 14 days.
The proposed technology is expected to significantly enhance India's lunar exploration capabilities by enabling spacecraft to endure multiple lunar day‑night cycles. Longer mission durations would allow scientists to conduct extended experiments, collect larger volumes of scientific data and improve prospects for sustained robotic operations on the Moon.
The development could also play a crucial role in supporting future human exploration missions and strengthening India's long‑term ambitions for a sustained presence on the lunar surface.
Narayanan earlier stated that India would need to launch over 200 satellites in the next three years to meet growing national and commercial requirements, calling for deeper participation from private industry, start‑ups and academia in the space sector.
He said India currently had 56 satellites in orbit but required more than 200 satellites in the next three years. He added that ISRO alone could not meet this demand and that the entire space ecosystem needed to work together, noting that there were many opportunities in the sector. He made these remarks at the 10th Industry Connect event organised by IN‑SPACe in Ahmedabad.

Impressive progress from ISRO. The 14-day limit was a major constraint, so extending to 200 days would open up serious scientific opportunities. I hope the heating tech is efficient enough to not drain too much power. This could be a breakthrough not just for India but for global lunar exploration.
ISRO just keeps delivering! From Chandrayaan-3's historic landing to this bold vision for extended lunar survival—our space scientists are truly world-class. The fact that they're working with DAE for artificial heaters shows how Indian institutions are pooling resources for ambitious goals. Proud moment for every Indian! 🌙🔥
This is clever engineering—solving the lunar night problem with artificial heating instead of relying on bulky batteries or RTGs. But 200 days still seems ambitious given the power constraints. I'm curious how they plan to generate enough energy during the day to sustain heaters through such long nights. Still, ISRO has surprised us before.
Great to see ISRO thinking long-term! Surviving 200 days would mean we can do experiments across multiple lunar cycles—collecting data on temperature variations, radiation, and soil behavior over time. This could be vital for future crewed missions. But I hope the budget doesn't get too stretched—we also need more satellites for Earth observation and communication.
I have mixed feelings. On one hand, extending lander lifespan is scientifically valuable. On the other hand, the focus on 200-day survival seems like a luxury when many villages in India still lack reliable electricity. Maybe we should prioritize solving basic problems on Earth before spending crores on Moon heaters? Just a thought.
