You are a brilliant pilot, and was chosed to an special mission: Protect our Planet of asteroids rain. Use your ability for destroy the asteroids as long you can.
To keep you defending as long as possible, our engineering team equiped the spaceship with electric engine, so, you don't need come back for fuelling, but, keep close to the sun to charge the battery, but pay attention to the temperature, the closer to the sun, the hotter it will get. If it exceeds 90%, the ship will be damaged.

Good Luck!
