On July 15, northern Maine will host the fastest run ever performed by humans: at “light speed” (186,000 miles per second) along the Maine Solar System Model. The run is being held in honor of the NASA New Horizons spacecraft which, after a nine-year voyage, will fly past and study Pluto in mid-July during the close encounter. As the first post-flyby images are returning to Earth at the speed of light on the morning of July 15, groups of runners will simulate the photo signal by running from Pluto to Earth along the Maine Solar System Model through the various small towns and villages in the rural northeast corner of the United States along U.S. Route 1.
