TITUSVILLE, Fla. — One of Hollywood's biggest stars shined bright Thursday night at Kennedy Space Center to celebrate the 50th anniversary of the Apollo 11 moon landing.

  • George Clooney helped celebrate Apollo 11 50th anniversary
  • Buzz Aldrin wore Omega wristwatch when he walked on moon
  • Astronauts Tom Stafford and Charlie Duke also attended event

The black-tie event with George Clooney involved Omega, the first wristwatch brand to be worn on the moon. The Hollywood leading man is the company's ambassador. 

The first man to walk on the moon — Neil Armstrong — didn't have the watch on his wrist when he stepped onto the powdery surface. He left his watch inside the lunar module as a backup because of a malfunction.

It was crewmate Buzz Aldrin who donned his watch when he walked on the moon July 20, 1969.

"When (President John) Kennedy said we are going to land a man on the moon, the idea, the thought that somehow that could ever be true was absolutely impossible," Clooney said.

Aldrin lives nearby on Florida's Space Coast but was not able to make the event.

Moonwalkers Tom Stafford and Charlie Duke also joined the celebration. Duke manned the Capcom on Apollo 11 and says using the watches during the mission was invaluable.
