The Pluto stamps are of special significance to NASA and the New Horizons team, which placed a 29-cent 1991 “Pluto: Not Yet Explored” stamp on board the spacecraft. On July 14, New Horizons carried the tiny postage stamp on its history-making journey to Pluto and beyond, as members of the mission team celebrated with a large print, striking the words “not yet.”
“The New Horizons project is proud to have such an important honor from the U.S. Postal Service,” said Alan Stern, New Horizons principal investigator from the Southwest Research Institute in Boulder, Colorado. “Since the early 1990s the old, ‘Pluto Not Explored’ stamp served as a rallying cry for many who wanted to mount this historic mission of space exploration. Now that NASA’s New Horizons has accomplished that goal, it’s a wonderful feeling to see these new stamps join others commemorating first explorations of the planets.”
The souvenir sheet of four stamps contains two new stamps appearing twice. The first stamp shows an artist’s rendering of NASA’s New Horizons Pluto flyby spacecraft and the second shows the spacecraft’s enhanced color image of Pluto taken by New Horizons near its closest approach to Pluto.
The view — which is color enhanced to highlight surface texture and composition — is a composite of images from New Horizons Long Range Reconnaissance Imager (LORRI), combined with color data from the imaging instrument Ralph that clearly reveals the now-famous heart-shaped feature stretched across Pluto’s surface; this feature has been named Tombaugh Regio in honor of Pluto’s discoverer, Clyde Tombaugh. Antonio Alcalá of Alexandria, Virginia was the art director for these stamp designs.
“Our stamps articulate the American experience through miniature works of art,” said Acting Stamp Services Director Mary-Anne Penner. “Our diverse stamp topics for 2016 are sure to appeal to everyone, and with the New Year just around the corner, now is a perfect time to get started in stamp collecting. It’s an educational hobby the entire family can enjoy.”
The “Pluto Explored!” stamps will be dedicated in late May of 2016 at the World Stamp Show in New York.

Views of Our Planets
With this pane of 16 Forever stamps, the Postal Service showcases some of the more visually compelling historic, full-disk images of the planets obtained during the last half-century of space exploration. Eight new colorful Forever stamps, each shown twice, feature Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Some show the planets’ “true color” — what one might see if traveling through space. Others use colors to represent and visualize certain features of a planet based in imaging data. Still others use the near-infrared spectrum to show things that cannot be seen by the human eye.

Celebrating the 50th anniversary of the television premiere, the new Star Trek Forever stamps showcase four digital illustrations inspired by the television program: the Starship Enterprise inside the outline of a Starfleet insignia against a gold background, the silhouette of a crewman in a transporter against a red background, the silhouette of the Enterprise from above against a green background, and the Enterprise inside the outline of the Vulcan statue against a blue background. The words “Space…the Final Frontier,” from Captain Kirk’s famous voice-over appear against a background of stars.
