From the result of the latest research, Juno will explode in 200 years, in that time, the droo civilisation will not exist, the inner planet of the Juno system will be burned up by Juno. So the United Government has stared funding the Wandering Droo Program, there will be steps:
1-Build Droo engines and underground cities, there will be engines around the Equator and in North Hemisphere, the engines around the equator will stop Droo from rotating, and this will cause tsunamis.
2-Push Droo to orbits will higher AP, this will last for years.
3-Push Droo to Tydos and use gravity assist to push Droo out of Juno System, and head to the destnation.
4-Wandering, this will last hundreds years, Droo will glide at 1% of light speed.
5-Breking, when at the destination system, we'll break Droo into orbit, and everything will become normal.
Requirement-A lot of money to build these engines, also a capable destination.
