Just months after the death of Leonard Nimoy, "Star Trek" fans have received more bad news on the health of another of the sci-fi show’s stars.

Nichelle Nichols, 82, who played Lt. Nyota Uhura in the original TV series and films, suffered a mild stroke this week, according to a post on her Facebook page, CNN reports.

“Last night while at her home in L.A., Nichelle Nichols suffered from a mild stroke," said the statement by Zach McGinnis of Galactic Productions, which books Nichols and other actors for public appearances.

"She is currently undergoing testing to determine how severe the stroke was," the statement continued. Please keep her in your thoughts."

Actor George Takei, Nichols' "Star Trek" costar, sent along his best wishes via Twitter: "We don't have any diagnosis on her condition but our thoughts are with her."
