Shatner's (@WilliamShatner) tweet -- notably, he is a Canadian himself, said:
@Cmdr_Hadfield Are you tweeting from space? MBBMBB, by the way, means "My Best, Bill."
Shortly thereafter, Hadfield (@Cmdr_Hadfield), a mechanical engineer and retired colonel in the Canadian Armed Forces, tweeted a response back from the International Space Station (ISS), without even using Uhura (Nichelle Nichols) as an intermediary.
@WilliamShatner Yes, Standard Orbit, Captain. And we're detecting signs of life on the surfaceHadfield will soon become Canada's first space commander. He launched into orbit in December aboard a Russian Soyuz spacecraft. Currently service as a flight engineer on the space station's six-man Expedition 34 crew, in March, he will take command of the ISS' Expedition 35 mission increment.
Officials with the Canadian Space Agency (@csa_asc) were quick to confirm to Shatner that Hadfield was, in fact, tweeting from space, with Shatner responding, "I'm very impressed!"
Shatner and Hadfield have met before -- sort of. The actor posed with a tiny paper version of the astronaut as part of a public outreach program for Hadfield's mission. Hadfield joked about the "meeting," tweeting:
The last time @WilliamShatner and I met was in another dimension - 2D From @csa_asc contest - http://www.asc-csa.gc.ca/eng/missions/expedition34-35/photo-challenge/ …) http://pic.twitter.com/Y7tECNL7These aren't the first tweets from space. Astronaut Mike Massimino was the first to tweet from orbit during the last space shuttle mission to the Hubble Space Telescope.
I'm proud of being Canadian, but after yesterday's twitter conversation am starting to question wearing this red shirt. http://pic.twitter.com/9iss6g0PThose aware of the fate of red-shirted crewmen on TOS are probably laughing. Notably, later series -- "Star Trek: The Next Generation," "Star Trek: Deep Space Nine," etc. etc. -- did not have the same tendency to kill off mostly red-shirted crewmen.
Hadfield is due to return to Earth in mid-May.
