Kanata no Astra

Description
In the year 2063, travelling through space has become commonplace. Eight students from Caird High School, along with one child, set out for a school camp on a nearby planet. However, the students are then mysteriously transported 5,000 light years away from home, with no way to call for help. Aboard an abandoned spaceship they call the Astra, these nine students slowly try to make their way back and figure out why they were transported in the first place. (from manga)
