Showrunner Alex Kurtzman revealed at San Diego Comic-Con that ahead of the new season of Star Trek: Discovery, CBS All Access was dropping four stand-alone episodes that would delve deeper into some of the show's ensemble cast. Now, we have an official premiere date along with our first look at the upcoming episodes!

The first episode of Star Trek: Short Treks drops Thursday, Oct. 4 following by three more in monthly installments. These 10 to 15-minute stand-alone adventures will explore the backstories of characters like the infamous smuggler Harry Mudd (Rainn Wilson), who double-crossed Lorca (Jason Isaacs) and Tyler (Shazad Latif) back in Season 1. Wilson will direct the Mudd-centric episode in addition to reprising the role.

Additional episodes will center on Underground's Aldis Hodge as Craft, a man stranded aboard a deserted ship, a deeper exploration of Saru's (Doug Jones) backstory as Starfleet's first Kelpian and Tilly's (Mary Wiseman) unlikely friendship aboard the U.S.S. Discovery.
