'Star Trek' fans are going to love this one.

It's been 54 years since the original 'Star Trek' debuted on TV. Thus CBS All Access are launching an all-day celebration of the entire franchise.

The special occasion will include panels from cast members across its series and a marathon of specially selected episodes.

Now unfortunately the marathon portion is only available to viewers in the US.

But the eight panels for the different 'Trek' series are free to viewers worldwide.

You can watch them at the 'Star Trek' website from 8 p.m. (or 12 p.m. PT/3 p.m. ET) on September 8th.

The panels will include:

  • 'Star Trek: Discovery' - features Sonequa Martin-Green and David Ajala (who is joining the show for Season 3); and co-showrunner and executive producers Alex Kurtzman and Michelle Paradise.
  • 'Star Trek: Strange New Worlds' (the new 'Discovery' spin-off series announced in May) - features Anson Mount, Rebecca Romijn and Ethan Peck; executive producers Akiva Goldsman and Henry Alonso Myers; and co-executive producers Akela Cooper and Davy Perez.
  • 'Star Trek: Enterprise' - features Scott Bakula, Linda Park, John Billingsley, Dominic Keating, Anthony Montgomery and Connor Trinneer.
  • 'Star Trek: Deep Space Nine' - featuress Terry Farrell, Alexander Siddig, Armin Shimerman, Nana Visitor, Cirroc Lofton; and executive producer Ira Steven Behr.
  • 'Star Trek' (the original series) - features George Takei and the CEO of Roddenberry Entertainment, Rod Roddenberry (the son of 'Star Trek' creator Gene Roddenberry).
  • New animated series 'Star Trek: Lower Decks' - features voice cast Tawny Newsome, Jack Quaid, Noël Wells and Eugene Cordero; and series creator, showrunner and executive producer Mike McMahan.

  • 'Star Trek: The Next Generation' and its sequel series 'Picard' - features Patrick Stewart and Jonathan Frakes.

Along with the event, a pub quiz will run on Twitch at midnight (or 4 p.m. PT / 7 p.m. ET).

'Star Trek' emojis will debut on Twitter and there'll be a flash sale of 'Trek' merchandise.

The hashtag #StarTrekUnitedGives will be trending during the event.

For every one who tweets it, CBS All Access will donate $1 to organisations that promote social justice and scientific advancements (such as the NAACP Legal Defense and Educational Fund, and the Equal Justice Initiative).

Other virtual fan events that have been hosted of late include Warner Bros.' DC FanDome: Hall of Heroes.
