A new preview has been released for what looks like a truly Trek-tacular episode of The Big Bang Theory.

CBS has released a new promo clip from “The Bakersfield Expedition,” which will air this Thursday at 8 p.m. The preview scoops the geeky gang decked out in no-holds-barred Star Trek cosplay (and flirting with the fate of redshirts) while Penny, Amy, and Bernadette venture into Stuart’s Comic Book Store of Manliness. Check out the preview right here:

Quick, Leonard! Vulcans are stealing your car!

And though we’ve certainly seen humans of a female persuasion visit the foreign turf of the comic book store before, it will be interesting to see what effect Amy, Penny, and Bernadette manage to have when their mysterious lady powers combine. Lasers set to stun, perhaps?

For a closer look at the boys’ fabulous costumes check out this promo photo below. (Frankly, we’re not sure anyone there is coming in peace.)

Picard in Leonard’s glasses! Howard in some kind of metal… something! And is that Raj?

The official summary for “The Bakersfield Expedition” says:

While the guys take a road trip to a comic book convention dressed as Star Trek: The Next Generation characters, the girls stay home and try to interpret a comic book.

What do you expect in ‘The Bakersfield Expedition’?
