By sending a scientist to the current planet, the player can gather soil samples that will give various bonuses until the current planet is destroyed. On certain planets, gathering soil samples also has a chance to yield rare minerals.
Scientists take 1 hour to travel to their destination. Planetary research is unavailable while scientists are travelling.
By paying some diamonds, it is possible to instantly send scientists to their destination. The price depends on the remaining travel time and the initial price is 10 diamonds.
When going to the current planet, scientists travel one at a time. When returning from a planet, scientists travel together.
All scientists instantaneously return to the player automatically:
- upon destroying the current planet
- upon entering a Black Hole
In all other instances the scientists will remain on the current planet until the player orders them to return.
