A solar eclipse will be occurring on August 21, 2017, and to commemorate the event, the United States Postal Service is issueing a special Total Eclipse of the Sun postage stamp. The Orlando Science Center will be one of the exclusive locations in the country to unveil the stamp design, at an informal presentation on Thursday, July 13.
Stamp-users (stampers? mailers?) will be able to change the image on the stamp using their thumb, from eclipse to a moon, or vice versa, made possible with thermochromic ink. The image is based on a photograph taken by Fred Espenak, taken on March 29, 2006 in Jalu, Libya.
After the event, attendees will be able to experience a presentation on eclipses at the Science on a Sphere and visit the Our Planet exhibition.
