This project is in honor of my son, Lorenzo, who had half a heart but filled ours full. Whenever I find a heart, I see Lorenzo in the world. Thank you for contributing the hearts you find and their meaning. Let's link up the whole world, one heart at a time.
• The Who: Commander Chris Hadfield
• The Where: Orbiting Earth on ISS
• The Link: "Seven billion hearts, but I can see only one. #ValentineFromSpace"
* With an extra special thank you to Bekki Lyon for sending this heart in my direction!
