This commemorative postal cover celebrates the Gravity Recovery and Interior Laboratory (GRAIL) mission, a groundbreaking effort to map the Moon’s interior and better understand its formation and evolution.
Launched in 2011 by NASA, the mission used two spacecraft—GRAIL-A and GRAIL-B—flying in formation around the Moon. By precisely measuring changes in the distance between the two probes as they orbited, scientists were able to create the most detailed map ever made of the Moon’s gravitational field. The data helped reveal new insights into the Moon’s internal structure, crust thickness, and geological history.
Featuring mission-themed artwork and a commemorative postal cancellation, this vintage cover captures an important chapter in modern lunar exploration.
A unique collectible for space enthusiasts and collectors interested in lunar science missions and the continuing exploration of the Moon.
