- The Indian Space Research Organisation (ISRO) has received no signals from the Chandrayaan-3 mission’s Vikram lander and Pragyan rover.
- All the modules of the mission are solar powered and were designed to last for just one lunar day or about 14 days on Earth.
- The mission’s electronics were not designed to withstand the extreme nighttime conditions on the Moon.
- The temperature drops well below minus 200 degrees Celsius near the lunar south pole where the lander and rover are.
- The Russian Luna-25 mission had a plutonium radioisotope device, which can be thought of as a kind of nuclear battery.
- It may help to generate heat that can keep instruments within an operable temperature.
- The Vikram Lander and Pragyan Rover have no such provisions.
