Your mission has failed. That much is certain. After all, it's not easy to cross the solar system and find life out there. You find yourself in a space laboratory where your samples have turned out to be worthless. But that's still the minor problem: the left tank of the space lab has a leak and liquid oxygen is leaking out. In 60 minutes everything will explode! You have to reach the space shuttle before then and start the flight back to Earth. Go!
