Twin Spica (ふたつのスピカ / Futatsu no Spica) is a Japanese seinen manga series written and illustrated by Kou Yaginuma. The “realistic, slice-of-life science fiction series” tells the story of a group of Japanese high school students training to become astronauts in the early 21st century after the country’s first human spaceflight launch ends in a disaster that causes many civilian casualties. The series is named after Spica, a binary star system and the brightest star in the constellation Virgo. The manga was adapted into an anime television series by animation studio Group TAC. It premiered on November 1, 2003, on Japan’s NHK BS Hi-Vision satellite service. Twenty episodes of the anime aired until March 27, 2004, when the series concluded prematurely before the manga was completed. Satellite television network Animax has broadcast the anime in multiple regional language releases, including English.
