On June 20, 2017, the US Postal Service issued a first-of-its-kind Total Eclipse of the Sun Forever stamp, which commemorates the August 21 eclipse. On July 2nd, we flew them to the edge of space 105,000 feet above central California. You can have a sheet of 16 stamps for the collector’s price of $89.95. They make great Birthday and Christmas gifts.
These rare temperature-sensitive stamps depict the Moon eclipsing the sun. When the stamp gets cold, the Moon darkens, forming a space-black disk. During our balloon flight on July 2nd, the temperature dropped to -63 C. The Moon darkened in the extreme cold of the stratosphere, then lightened again when the payload parachuted back to Earth, landing on the warm foothills of the Sierra Nevada mountains near Big Pine CA. The recovered stamps are perfectly in tact and continue to change their appearance as intended when exposed to heat and cold.
The Total Eclipse of the Sun stamp is a Forever stamp, which is always equal in value to the current First-Class Mail 1-ounce price.
Each sheet of 16 stamps comes with a unique gift card showing the stamps floating at the top of Earth’s atmosphere. The interior of the card tells the story of the flight and confirms that this gift has been to the edge of space and back again. You will receive the stamps in a black protective envelope that protects the stamps from UV radiation and preserves them for future gift-giving.
