NASA astronaut Terry Virts on Saturday paid tribute to "Star Trek" actor Leonard Nimoy, tweeting a photo of him performing the famous Vulcan salute from space.
The gesture was invented by Nimoy and popularized by the 1960s show. It was accompanied by the spoken phrase, "Live long and prosper."
At the time of publication, Virts' tweet had already received more than 22,000 retweets.
Nimoy died Friday of end-stage chronic obstructive pulmonary disease at his Los Angeles home, with family at his side, said his son, Adam Nimoy. He was 83.
