New Horizons US Postage Stamp Concept

Explanation: In 2012 the New Horizons mission team announced plans to have a stamp issued by the US Postal Service commemorating the New Horizons spacecraft and its targets, Pluto and Charon. Thousands of people signed a petition, clearing the first step in the USPS approval process. The stamp concept is now under review and consideration before the Citizens' Stamp Advisory Committee.
