Mission: 02 contains the first four chapters of Twin Spica and three additional short stories set in the world of the property.
Where were you when the first International Space Station was scrapped and dropped into Earth's atmosphere? It was Asumi's first day in space school, and she promised Lion she would not cry or be homesick as she will be leaving her quiet seaside town for the big city.
Waiting for her in Tokyo will be a lot of work. She is going to have to go through the rigors of space exploration training at the Tokyo Space School. After hours, Asumi will focus her efforts on homework, when not earning her tuition at the neighborhood Denny's. It is not unccomon to run 20 laps around the campus each day. Follow that up with physics and advance mathematics courses in the classroom. Only to close the night by mapping out the constellations in the southern sky. This is just what she expected the TSS to be, and yet why is it so hard to invision going to space someday? With all of the work she and her classmates are efforting, why does space still feel so far away?
