Notaro is tapped to guest-star as Chief Engineer Denise Reso and will be on board the U.S.S. Hiawatha in the sophomore season. Reso is a new character as she has no history in "Star Trek" lore. Fans, however, speculate that the character will be giving some clues at how she comes in contact with the Discovery crew.
It remains to be seen in how many episodes she will appear.
Her casting comes in the wake of the cancellation of her critically-acclaimed Amazon series "One Mississippi". Besides "Star Trek: Discovery", the actress is set to star in upcoming movie "Instant Family".
Notaro will be joining "Marvel's Inhumans" actor Anson Mount, who was recently tapped to star in the new season. Mount, who portrayed Black Bolt on the Marvel series, is set to play the famed Captain Christopher Pike of the U.S.S. Enterprise on "Star Trek: Discovery".
EP Alex Kurtzman previously revealed that the sophomore season would be addressing long-existing fan questions regarding Discovery Cmd. Michael Burnham (Sonequa Martin-Green) and the original "Star Trek" series' Spock's relationship. He, however, assured fans that the introduction of Enterprise would not overshadow the Discovery and its crew.
"The show is called 'Discovery'. It's not 'Enterprise'," Kurtzman said. "So yes, the Enterprise will play a part of season two but it will absolutely not overshadow Discovery. And I think with Enterprise's arrival in the finale we recognize that the audience has a lot of questions about our synchronicity with the original series, which really means or synchronicity with canon."
There is no word about the release date of season 2 of "Star Trek: Discovery".
