Perhaps one of my more favorite anime titles lately is “Space Brothers”. A story of two brothers whose encounter with an UFO spurs them to become astronauts. This series follows the two brothers through their trials and tribulations on the way to becoming astronauts. With collaboration from JAXA and NASA, this series as a feel of greater accuracy.
There is the occasional bit of language, but not much. That being said, I would recommend this a great drama / science (future) show. Good to get ones feet wet with in anime of you like long running story arcs.
This show can be seen in its current season as well as prior episodes at Crunchyroll.com.
