The U.S. Postal Service has launched two sets of “Forever” stamps that depict images from NASA‘s New Horizons Pluto probe as well as photos of the eight planets.
USPS said Tuesday the first-day-of-issue dedication ceremony for the Pluto—Explored! and Views of Our Planets stamps was held at the World Stamp Show-NY 2016.
“In 1991, the Postal Service issued a Pluto: Not Yet Explored stamp that served as a rallying cry for those who very much wanted to explore it,” said David Williams, USPS chief operating officer and executive vice president.
“I’m thrilled that 25 years later, these new stamps recognize that Pluto has indeed been explored by the New Horizons spacecraft and revealed to be a complex and fascinating world,” said Alan Stern, principal investigator for the New Horizons mission.
USPS noted that Antonio Alcala, an art director from Alexandria, Virginia, designed the stamps.
The New Horizons spacecraft flew by the dwarf planet in 2015.
