The logo for the 50th anniversary of the Apollo 11 moon landing gives a nod to the past with a few elements borrowed from the original Apollo program emblem, and a glimpse into the future with a graphic depiction of NASA’s vision for the next half-century of deep space exploration. The arc through the word “Apollo” represents Earth’s limb, or horizon, as seen from a spacecraft. It serves as a reminder of how the first views of Earth from the Moon – one of NASA’s crowning achievements – forever transformed the way we see ourselves as human beings. It also affirms NASA’s intention to continue pushing the boundaries of knowledge and delivering on the promise of American ingenuity and leadership in space. Credits: NASA/Matthew Skeins
