One of the few people in history to walk on the moon recently became one of the few people in the world to push a big red button in the control center at the Large Hadron Collider. During a visit to CERN on March 1, American astronaut Buzz Aldrin was allowed to dump the beam at the LHC.
Aldrin was in town for an event at CERN's Globe of Science and Innovation and took advantage of the opportunity to get a behind-the-scenes tour of the lab. Before he left, he stopped to chat about his impressions of CERN and large scientific missions in general.
"We're always dealing with trying to explore a little bit further," he said. "I suspect we're only scratching the surface."
