Buzz Aldrin Sends Message in Epic Stonehenge Pic It's 'get your ass to Mars' By Arden Dier, Newser Staff Posted Mar 18, 2015 10:07 AM CDT 19 comments Comments Buzz Aldrin sends a message to Mars in this photo taken at Stonehenge. (Twitter/James O. Davies) (Newser) – Buzz Aldrin may have just topped his selfie from space. While visiting Stonehenge on Sunday, the 85-year-old astronaut and second man to walk on the moon channeled Superman to pose for an epic tourist photo, in which he opens his jacket to reveal a shirt reading, "Get your ass to Mars." Aldrin shared the photo on his Twitter account with the hashtag #GYATM and the caption, "I decided to send a message to the cosmos." The BBC reports it's all part of his campaign to boost interest in further space exploration. Apparently after receiving several questions about the photo, a rep for English Heritage, the charity in charge of caring for Stonehenge, confirms the snapshot is indeed real. The rep says Aldrin was at the ancient landmark for a "private visit for him and his family. We were told about it a week or so ago and everyone was very excited about meeting him." She says Aldrin was particularly interested in "where we hide the aliens." Aldrin has been spotted wearing the Mars shirt in the past in support of his ShareSpace Foundation, which backs science, technology, engineering, arts, and math education, USA Today reports. CNN points out Aldrin has previously expressed his support for a "permanent presence on the planet Mars," noting, "The moment to begin could be on the occasion of the 50th anniversary of Apollo 11's touchdown on the moon" in 2019.
