By now, you’ve likely heard about the passing of actor Leonard Nimoy, 83, best known for his role as Spock, the Vulcan with a heart, in the cult TV series "Star Trek."

Chances are you first read word of his death on Facebook or Twitter, as tributes trended, including #RIPLeonardNimoy, #livelongandprosper and #LLAP.

Perhaps one of the most touching came from NASA, who thanked him for inspiring their work. Attached was a photo from September 17, 1976, which pictures Nimoy and other members of the "Star Trek" cast in front the Space Shuttle Orbiter Enterprise, named after the famed U.S.S. Enterprise from the show.

According to NASA, the ship (the real life one) was supposed to be named the Constitution, but to change the name – and they won.

NASA’s Twitter tribute is fitting for an actor who was active on social media himself. Earlier this month he commented on the terrible winter his hometown was having.

Nimoy died Friday of chronic obstructive pulmonary disease at his Los Angeles home with family at his side, said his son, Adam Nimoy.
