La Terra è vista tramontare sul lato opposto della Luna dietro la navicella Orion in questo video catturato il giorno 6 della missione Artemis I da una telecamera sul bordo di uno dei pannelli solari di Orion. La navicella si stava preparando per una manovra Flyby a motore spento che l’avrebbe portata entro 80 miglia dalla superficie lunare, l’approccio più vicino per la missione Artemis I senza equipaggio, prima di spostarsi in una lontana orbita retrograda attorno alla luna. Il veicolo spaziale è entrato nel campo di influenza lunare domenica 20 novembre, rendendo la Luna, piuttosto che la Terra, la principale forza gravitazionale che agisce sul veicolo spaziale. a lui attribuito:[{” attribute=””>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:
