Earlier this year at San Diego Comic Con, Star Trek: Discovery Executive Producer Alex Kurztman announced that the series would have its return to streaming preceded by four stand-alone digital shorts based in the same time period as Discovery and featuring familar characters from the show. The fan base has been anticipating when these shorts would be scheduled. Yesterday, CBS All Access announced the first of the shorts will be released in two weeks on Thursday, October 4. The other digital shorts will be released on the first Thursday of November and December 2018, and January 2019.
Each of the stories will feature a character we were introduced to during Season One, giving us more insight into them and possibly about the themes explored in Season Two. We will experience story centered around Ensign Tilly (Mary Wiseman), Saru (Doug Jones) and Harry Mudd (Rainn Wilson), as well as one short that will introduce a new character named Craft played by actor Aldis Hodge. Craft is expected to play some part in the story arc for this season.

The premiere release dates and detailed descriptions of all four are as follows:
