Glastar

Several potentially deadly asteroids and meteors were detected on radar heading towards planet Earth, threatening life on the planet. The countries had to come up with a plan to create a manned spacecraft strong enough and with a laser powerful enough to destroy these asteroids. Your mission is to destroy these asteroids heading towards planet Earth (or Mars).
