The scene, a single high school girl sits in a classroom, becoming ever more lost as a formula for Hohmann transfer orbits fills the white board. When she complains that some of the numbers are seven digits the instructor points out she has been given a calculator. As she looks at the calculator she's stunned by the number of buttons on it, only to be even more shocked by a realization...
"There's no equals key!"
"Of course not! Don't you know reverse Polish calculation?"
"Of course not!"
"Oh, really?" An all to excited look appears on the instructor's face. "In that case I'll take five minutes to cram its operation into your head. When I'm done with you, you'll never be able to use a regular calculator again. Prepare yourself."
Our vict-- er, high school girl has traveled to the Solomon Islands to search for her father who disappeared years before on her parents honeymoon trip. Meanwhile a Japanese company wants to build a new manned rocket to operate from the islands -- their only problem, their current astronaut (on loan from the JSDF) is about forty kilo's too heavy for their only reliable model's payload capacity -- while our main character is actually a couple kilo's less than that target weight. So a deal is struck. The Solomon Islands Space Agency will use its contacts to help search for the missing father, and she will be their astronaut so they can get a successful launch before the end of the year and keep their funding.
I think I'll be keeping my eyes out for this one on DVD. So what if it's still airing in Japan, somebody go and license it already.
EDIT: D'oh! jeriendhal
points out I never mentioned the title. The anime in question is called Rocket Girls. If there were still a good nearby independent store that carried anime I'd tell them this is on my guaranteed buy list. (Stuck with the chains as the nearby stores, no point telling the staff there, more than likely will be gone in a few weeks let alone by the time this is licensed and released)
