Of course, however we should remind you that energy donations from other members on the current planet will be deleted and cannot be recovered.

When cancelling research on a planet, it will lose any energy it has received and the energy won't be transferred to the next planet you choose. If you're sure you want to change to a new planet, go to Walkr > Menu > Social, tap the planet that you're researching and tap X in the message box that appears. You will then be able to select another "hungry" planet to research.
