Blast Off!

Luke, Yasmin and Yuri have been stuck on the Buzz Aldrin
spaceship for so long that they can barely remember what living on
polluted planet earth was like! So when the colony finally finds an
earth-like planet that seems safe to land on, they can''t believe their
luck. But when the trio of friends accidentally stumble across an
abandoned alien city, tripping the planet''s self-destruct system in the
process, it seems that all their dreams of leaving life in space behind
are about to go out with a bang. Can they save the planet, or at least
save themselves, before blast off?
