He's still got it. Legendary astronaut Buzz Aldrin took to Twitter to send "a message to the cosmos" and continue to push for space exploration.

Posing in front of Stonehenge, he stood in full-on Superman stance -- pulling open his button down to reveal a message tee.

His t-shirt reads, "Get your a** to Mars."

Well, okay then, Buzz.

The messaging is all part of his ShareSpace foundation, which encourages innovation among kids in the fields of  science, technology, engineering, arts and math.
