NASA's New Horizons Spacecraft Reaches Another Milestone!

 

On April 18 at 12:42 UTC (or April 17 at 8:42 p.m. EDT), New Horizons will reach a rare deep-space milepost -- 50 astronomical units from the Sun, or 50 times farther from the Sun than Earth is. It will be 7.5 billion kilometers from Earth. New Horizons is just the fifth spacecraft to reach this great distance, following the legendary Voyagers 1 and 2 and their predecessors, Pioneers 10 and 11.
