FREE: SC1193 PROJECT MERCURY 1962 MNH Suprise Issued Same Day as Launch - John Glenn First US Man in Space

305 postoffices all over the country released the Project Mercury stamp for sale to the public at 3:30 pm upon the successful splashdown of Astronaut John Glenn Jr,. This stamp was designed and printed in secret and distributed to the 305 post offices. Even these post offices did not know what they had received until word was given to open the packages and put the stamps on sale.

The 1962 4-cent "Project Mercury" stamp marked the first time that the U.S. issued a previously unannounced commemorative stamp at the same time as the event it was issued to honor: John Glenn’s historic Friendship 7 spaceflight.

Fifty years ago today (Feb. 20), John Glenn, the first American to orbit the Earth, relied on ground stations located across the planet to communicate with his control team. But after his Mercury spacecraft, Friendship 7, safely splashed down, it was another type of station that took over tracking his historic mission: U.S. post offices.

For the first and only time in the country's postal history, the United States Post Office Department — since 1971, the U.S. Postal Service — surprised the public with the release of a secret stamp celebrating Glenn's successful mission. The 4-cent "Project Mercury" postage stamp was revealed and immediately put on sale in 305 post offices within an hour of Glenn's triumphant return to Earth at 2:43 p.m. EST (1943 GMT) on Feb. 20, 1962.

Half a century later, collectors are still searching for those first-day-of-issue stamps.


"The U.S. Post Office Department signaled the first orbital flight of a United States astronaut today with the issuance of a commemorative stamp, placed on sale throughout the country on the exact hour Astronaut John Glenn's historic flight was officially completed," the department stated. "It is the first time in history that a previously unannounced commemorative stamp was issued simultaneously with the event it memorializes."
