Let’s Reckon Time Together

Bill Nye • March 20, 2013

The EarthDial project was born in 2004, and we’re bring it back again for the Curiosity mission. It’s a sundial visually reminiscent of the MarsDials, but exactly ten times as big. We encourage you to set up your own EarthDial, rig up a webcam, and post the images. In the coming weeks, we’ll coordinate the EarthDials from around the world, just as we did for a few years after the Spirit & Opportunity landings. It’s a remarkable project that can engage individuals, classrooms, or entire schools. The price of webcams has come way down in recent years. So, we’re hopeful that several readers of this blog will give it a try.
