ISRO and the Department of Atomic Energy (DAE) are tackling one of the toughest challenges in lunar exploration: surviving the Moon’s freezing nights. During lunar nights, temperatures plunge below –100°C, which quickly disables electronics and batteries. Current landers like Chandrayaan‐3 only operate for about 14 Earth days — one lunar day — because they rely solely on solar power. Once the lander shuts down, no further experiments or communication are possible. ISRO and DAE are jointly develo
