Set in the year 2098, in "Galactic Mission" five school children have won an international competition to visit outer space and journey to the distant star system of Alpha Centauri on the spaceship Argo to find a new home. But right from the start things don't go according to plan -- conflict, malfunctions, mistrust, and running out of fuel all get in their way of trying to enter Alpha Centauri's atmosphere. Will they all make it back alive? Will they discover a new planet with great potential for human life to survive?
