Episode list

Yukari Morita visits the Solomon Islands during summer vacation to search for her missing father, who disappeared on her mother's honeymoon. Meanwhile, the Solomon Islands Space Association's latest rocket has another launch failure. If they don't succeed soon, their budget will get canceled.

Nasuda offers to help Yukari search for her father while she works for him as an astronaut. Her acceptance is followed by embarrassing medical examinations, continuous training, live-fire weapons training, and the discovery she has to wear a 3 millimeters thick spacesuit.

Tests of the new rocket fuel go consistently and catastrophically wrong, but the director hides the events from Yukari and Matsuri. With Matsuri now an astronaut trainee, Yukari attempts to gain weight and show a poor attitude in order to be kicked off the program.

Yukari decides to take a hands-on attitude to her job, and gains entry to the capsule construction site.

Yukari's mother arrives and sets the agenda for the upcoming launches. Yukari and Matsuri are introduced to the media ahead of the first launch, which is repeatedly delayed.

Yukari's capsule suffers a serious problem. Matsuri is launched in another rocket to provide some extra oxygen as the ground crew tries to determine a solution.

Akane Miura, a top student at the school, provides vital help in preserving the goldfish. As Yukari has fulfilled her promise of going into space once, she plans to go back to school just as Akane expresses a desire to go to space.

Akane starts astronaut training, but she fails a number of physical tests.

Yukari is heartbroken at hearing that Akane left the training program, but the director and the rest of the SSA staff are actually hiding the truth from her.

The space shuttle Atlantis is preparing to launch the Pluto probe Orpheus, but they lose a vital part within the tight confines of the probe and are unable to extract it. The SSA begins planning a rescue mission using their new two person capsule named Mangosteen.

Yukari and Akane begin their mission to the Atlantis to extract the part.

Yukari and Akane reach the Orpheus, but the return trip may be too much for the Mangosteen.
