Astra Lost in Space is a Japanese manga created by Kenta Shinohara, which was published digitally from May 2016 through December 2017 on Shueisha's Shōnen Jump+ platform. The narrative was collected into five volumes, with an English edition released by Viz Media. An anime adaptation produced by Lerche aired between July and September 2019.

Plot

Taking place in the year 2063, when commercial space travel has become commonplace, nine students attending Caird High School set out on a Planetary Camp to the planet McPa. Soon after their arrival, a mysterious intelligent sphere of light transports them across vast distances in space. They find themselves orbiting an unfamiliar planet, where they discover and restore an abandoned spacecraft, which they name Astra. Their objective becomes to navigate the 5,012 light-years back to Earth. Along their journey, they stop at various alien worlds—each bearing names that are anagrams—to collect necessary supplies and ensure survival. Throughout this expedition, the characters’ personalities unfold more deeply, and the stakes intensify beyond their original mission.
