Rocket Girls

Yukari Morita had no clue how far her search would lead her when she made the decision to go for her father, who had vanished in the South Seas. For a high school student to simply go to the Solomon Islands is a significant distance, but Yukari then meets an astronaut from the Solomon Space Association, which has been working to develop a rocket powerful enough to send a man into space. However, SSA director Nasuda discovers that the little Yukari is small enough to fly in a less potent rocket the SSA has already developed! So he makes her a deal: if Yukari accepts to join their crew as an astronaut, the SSA will assist in locating her father. Will Yukari have what it takes to launch on the craziest space mission ever?
