Happy First Contact Day! Star Trek fans are being treated to so many exciting reveals — including our first look at Season 4 of Star Trek: DiscoveryThe trailer drop was part of a special virtual event honoring the anniversary of "First Contact Day," in which humans became aware of life on other worlds through a first meeting with the Vulcan race on April 5, 2063 (an event that played out in the movie Star Trek: First Contact).

We knew Discovery would be coming back for Season 4 back in November, when the cast was reported to return to begin production, and the new trailer gives us our first indication of the trials that await Captain Michael Burnham (Sonequa Martin-Green), Saru (Doug Jones) and other DISCO crew members like Paul Stamets (Anthony Rapp) and Sylvia Tilly (Mary Wiseman). The trailer also serves as confirmation that Season 3 newcomers David AjalaBlu del Barrio and Ian Alexander will also be coming back for the fourth season — and teases a very important shot of Book's cat Grudge, a new fan-favorite character.
