Tomorrow brings the second episode of Star Trek: Discovery’s second season, and today we’ve got more to preview from “New Eden,” bringing Jonathan Frakes back to the director’s chair!

First, in case you missed it, the episodic trailer which arrived last night via Netflix’ social media feeds:

Today, CBS has revealed a number of new photos from tomorrow’s episode, which features the Discovery crew encountering a seemingly unexpected human colony along their voyage.

Here’s the breakdown:

A new signal appears, prompting Stamets’ emotional return to the mycelial network and leading Burnham, Pike and Owosekun to a pre-warp planet, where they face a complex ethical dilemma.

Tilly’s overeagerness lands her in trouble but when the planet – and Discovery’s landing party – are threatened, her curiosity may be the one thing that can save them.

Along with the photos and trailer, CBS also shared this montage video of director Frakes on the Discovery set — returning after his first stint on the show last season — while his fellow Next Generation co-star Marina Sirtis visited the production back in May, which Mary Wiseman previewed last year.

Finally, new Discovery captain Anson Mount shared some personal photos from the set on Twitter today, showcasing the first time he — and his dog Mac — got to sit in the captain’s chair.
