At San-Diego Comic Con the first trailer for Star Trek: Discovery Season 2 made its debut. At a panel moderated by Tig Notaro--who also plays new character Reno in Season 2--and attended by executive producers Alex Kurtzman and Heather Kadin, the crew of the USS Discovery were shown beginning a brand new voyage.

Anson Mount joins the show as Captain Christopher Pike and has taken command of the ship under orders from Starfleet. During the panel it was also confirmed that beloved Star Trek character Spock will be seen in the season, and he is even a focal point in the narrative. Season 2 is set to begin airing in January 2019, but there will be four short films called "Short Treks" that will begin releasing from September.
