Remember watching the first moon landing on July 20, 1969? There’s a new TV audience waiting to hear your memories of that giant leap for (hu)mankind — and an opportunity to win a trip with your kids and grandkids to celebrate the 50th anniversary of Apollo 11’s famous journey.

Grown-up space cadets are invited to submit a photo and their memories of the lunar landing.

The producers of NBC Universal Kids’ Space Racers have launched a nationwide contest for grandparents to tell their Apollo 11 stories.

Space Race LLC is inviting grown-up space cadets to submit a photo and their memories of the lunar landing to www.SpaceRacers.com/Apollo before its July 1 deadline.

The grand prize: a three-day, two-night trip to Orlando, Florida, that covers four people and includes a “One Day Space Adventure” at the Kennedy Space Center Visitor Complex. Additional prizes include telescopes, binoculars and a passel of Space Racers merch.

After the July 1 submission deadline, Space Racers and Kennedy Space Center Visitor Complex choose the 12 most compelling Apollo 11 memories, then turn the voting over to the public until July 8.

If your family’s smallest astronauts would like a trip to Orlando — or a pile of plushies and a chance to share your memories of that historic day — take a shot at this space race.
