In the year 2063, space travel is feasible and commercially available. As the cheerful Aries Spring arrives at the spaceport to attend a camp on the distant planet McPa, her purse is suddenly snatched by a reckless thief. Luckily, the athletic Kanata Hoshijima is able to retrieve it for her, and Aries soon discovers that he is among the group of teenagers who will be traveling with her on the excursion as team B-5.

Upon arriving at their campsite, the group's trip takes a turn for the worse when a strange sphere of black light sucks them into the vast reaches of outer space. Stranded with seemingly no hope, they find an abandoned ship nearby that provides them with the means to return home. However, they soon discover that they are not as close to their campsite as they initially thought, but are in fact thousands of light-years away from home.

With this realization, the nine members must cautiously manage their resources, maintain their strength, and unite as one to conquer the darkness of space together. While the reason behind their trip's sudden obstruction remains unknown, they nevertheless embark on the treacherous voyage back home aboard their new ship, the Astra.

Around a Hundred years down the line from now, we might have human colonies on habitable far away planets and space travel might be common place. It may seem farfetched right now, but then again, who could’ve imagined the progress in technology humankind has made in the last half a century? While learning about the different planets and galaxies, almost every kid might have had a fleeting dream about going into space and experience what it may be.

Mixed Feelings
Almost one hour long and a wide screen aspect ratio, those were my first impressions of the first episode of this anime. Astra in Space caught my attention from the info of its source material than anything else. A well received shounen oriented sci-fi adventure, and not only that, but it’s also short being only 5 volumes long. With a story that short it seemed that Astra had something that it wanted to accomplish. However as the episodes ticked by i failed to see what it was trying to do with its story or why it was considered good. Sure it is enjoyable, but that’s ...

Kanata no Astra could be an anime that surprised several viewers. In my case, I was bewitched by some episodes until I noticed that the show is mediocre science fiction with several plot flaws and unfinished ideas.

The scenario is good at the beginning; A group of students is drifting in the dark space with only one goal in mind, returning home. I was surprised to the point that I ignored the strange CGI moments when the characters looked like dead puppets in the first episode. I ignored the device created in a few hours that could diagnose if the food is good or bad with ...
