John Glenn Memorialized with 'Godspeed' Radio Hail Turned Hashtag

The same phrase that hailed John Glenn's historic launch into space more than 50 years ago became a social media hashtag on Thursday (Dec. 8), marking the astronaut's final departure from Earth. "#GodspeedJohnGlenn," read the tweets, status notes and photo captions as the news spread that John Glenn had died at the age of 95. "Very sad to hear about the passing of John Glenn, last of the Original 7 American astronauts," wrote Mark Polansky, a former astronaut, on Twitter.
