RTGs need plutonium 238. I've read even US doesn't have a lot available. The Europa Clipper will be using solar panel for example. India could also use batteries and a standby mode during the 14 days without sunlight. But any extra weight would add to the launch cost. Maybe in future missions as they get confident with successful landing, they will have bigger lander that can survive the lunar night. Even the early Mars rovers from NASA were tiny and solar powered (ie Sojourner in 1997.) |
