After originally releasing a Planetes Blu-ray box set back in September 2009, Japanese distributor Bandai Visual opted to bring it out again back in 2016.
They were intending to bring it out in late 2020 but it’s now been set for an April 26th, 2021 release.
The series was originally serialized in Morning magazine back between 2001 and 2004 by Makoto Yukimura, whose other big release is the currently running series Vinland Saga that he began back in 2005.
