See the Far Side of the Moon: Incredibly Detailed Pictures From Artemis I Orion Close Lunar Flyby

The Earth is seen setting from the far side of the Moon just beyond the Orion spacecraft in this video taken on the sixth day of the Artemis I mission by a camera on the tip of one of Orion’s solar arrays. The spacecraft was preparing for the Outbound Powered Flyby maneuver which would bring it within 80 miles of the lunar surface, the closest approach of the uncrewed Artemis I mission, before moving into a distant retrograde orbit around the Moon. The spacecraft entered the lunar sphere of influence on Sunday, November 20, making the Moon, instead of Earth, the main gravitational force acting on the spacecraft. Credit: NASA

On the sixth day of the Artemis I mission, Orion made a close flyby of the Moon, passing about 81 miles (130 km) above the surface. During the close flyby, Orion’s optical navigation camera captured black-and-white images of craters on the Moon below. Orion uses the optical navigation camera to capture imagery of the Earth and the Moon at different phases and distances, providing an enhanced body of data to certify its effectiveness under different lighting conditions as a way to help orient the spacecraft on future missions with crew.

The Earth and Moon are tidally locked, which means that the Moon spins on its axis exactly once each time it orbits our planet. Because of this, people on Earth only ever see one side of the Moon. In fact, humans didn’t see the lunar far side until a Soviet spacecraft flew past in 1959. This side we never see is known as the “far side of the Moon.” Sometimes it is called the “dark side of the Moon,” which some people consider a misnomer because it gets just as much sunlight as the near side of the Moon. However, “dark” in this case is referring to unknown, rather than a lack of light.

Here are the detailed images of the Moon captured by Orion’s optical navigation camera:
