July 20 marks the 50th anniversary of the first moon landing. To commemorate the occasion, the U.S. Postal Service is releasing two new forever stamps. The first features a photo of Buzz Aldrin in his spacesuit on the surface of the moon, while the second is a shot of the moon in the night sky, with the Apollo 11 lunar module landing site in the Sea of Tranquility marked with a yellow dot. An image of the lunar module itself will be included on the selvage of the stamps, which will be released later this year.
