Birth control vaccines have been invented that will prevent doe from having fawns for up to 3 years. [14] These vaccines can be administered by dart or by a shot.
The solar arrays provide power for the aircraft's electric motors, avionics, communications and other electronic systems. Pathfinder also had a backup battery system that can provide power for between two and five hours to allow limited-duration flight after dark. [3]
