Planetes Picture Drama is a short 9 episode "Deleted Scenes" complication. Each episode is 3 minutes long and is in various mediums, but all are pretty much storyboards. Each episode is set in the background of certain episodes in the series and helps to flesh out some of the characters, but it's obvious why they would not include them in the original series.
The majority of them involve the Chief and Lavie in some form, so expect their usual comedic ways from the original series. One in particular has a more serious tone around Hachimaki's situation in the later episodes involving Fee and Yuri, which I enjoyed the most.
It's worth a watch if you were a fan of the original series!
