The United States Postal Service is now offering a passport to visit space exploration history.

The "Postal Passport to the Galaxy" promises its holder "a journey through space in stamps." The collectible booklet, which is also advertised as the "Sally Ride Folio," was first introduced by the U.S. Postal Service (USPS) on the same day it released a new postage stamp for the first American woman in space.

"Adventure through outer space with this postal passport," the USPS writes on its website, promoting the $25.95 item, "discovering incredible milestones of space exploration." [Giant Leaps: Biggest Milestones of Human Spaceflight]
