LONDON, March 17 (UPI) -- American astronaut Buzz Aldrin appeared in a viral photo at Stonehenge to send a message to humanity: we need to get to Mars.
Looking up to the heavens with the ancient landmark in the background, Aldrin wore his famous "Get your ass to Mars" shirt.
Aldrin has stated the need to not only visit but colonize the Red Planet. The shirts are sold by his non-profit ShareSpace foundation which promotes science, technology, engineering and math, or STEM, education.
The shirt is available in a variety of styles on the ShareSpace website.
